• Implemeting web-based autocomplete for structured input

  - by ravigad

  I am looking to implement web-based autocomplete for structured commands. So, for example, suppose I was trying to implement a web-based Windows command line with autocomplete, in such a case I would want to suggest all the available commands, then, once a user selects a command, all the options for that command, then if a user enters a switch (say '-' dash or '/' slash) then offer all the switches for that command and all the relevant values that can follow, and so on. All from the same text input box. If you have used version 4.0 of JIRA, I am thinking of something similar to the JQL search input box that they have implemented. I have not managed to find any tutorials that look at this scenario end-to-end (which is a shame, because it would be great to see more applications that do this). What I am looking for is some guidance on the steps needed to implement this solution: Do you have any experience implementing such a solution and if so what components did you use? Would you use a framework such as ANTLR to provide the available options to the end user? If not what would do? Sorry for raising such a general question, but my main problem is working out how the pieces fit together as opposed to, say, how to do autocomplete or how to parse/tokenize an input command...

• Detecting when a cell's detail-disclosure button has been clicked (when using a custom cell XIB)

  - by Gloria

  1 if (cell == nil) 2 { 3 [[NSBundle mainBundle] loadNibNamed:@"TVCell" owner:self options:nil]; 4 cell = tvCell; 5 self.tvCell = nil; 6 } There's some code from an Apple example of using your own "custom cell XIB" to create cells in a UITableView. It appears to work... but I think I would do better to actually UNDERSTAND what is being done there. Why isn't line #3 assigning the value TO something? cell = [[NSBundle mainBundle] loadNibNamed:@"TVCell" owner:self options:nil]; (In fact, cell and tvCell aren't being used at all.) Why is line #4 assigning using tvCell when nothing has been put it in at all, yet? Why is line #5 nulling out the tvCell that I need? Why is "@property (nonatomic, assign) IBOutlet UITableViewCell *tvCell;" using assign, not retain? About the only thing I can't get working correctly is when I put a disclosure-button on my custom cell XIB. Is there a way for me to detect when the user has clicked on it? (Hopefully, without using 100s of TAGs.)

• ajax checkbox filter

  - by user1018298

  I need some help with a checkbox filter I am working in. I have four groups of checkboxes (type, vehicle, availability, price) and I would like to filter the content on the page based on the user's input. I can get the filter working OK but I am having issues with the groups. I can only seem to match one checkbox from each group rather than all checkboxes from each group. For example, a visitor can select 1 option in group 1, all options in group 2, 1 option in group three and 1 option in group 4. I am using ajax to build an SLQ query to return the correct filtered results from my database. here is my code: $('div.filters').delegate('input:checkbox', 'change', function() { var type = $('input.exp_type:checked').map(function () { return $(this).attr('value'); }).get().join(','); var vehicle = $('input.vehicle_type:checked').map(function () { return $(this).attr('value'); }).get().join(','); var avail = $('input.availability:checked').map(function () { return $(this).attr('value'); }).get().join(','); var price = $('input.price:checked').map(function () { return $(this).attr('value'); }).get().join(','); //alert($options); $.ajax({ type:"POST", url:"filtervouchers.php", data:"type="+type+"&vehicle="+vehicle+"&avail="+avail+"&price="+price, success:function(data){ $('.results').html(data); } });//end ajax }) and the php code: $type = mysql_real_escape_string($_POST['type']); $vehicles = mysql_real_escape_string($_POST['vehicle']); $avail = mysql_real_escape_string($_POST['avail']); $price = mysql_real_escape_string($_POST['price']); if ($type != '') { $sql2 = " AND exp_type IN ($type)"; } if ($vehicles != '') { $sql3 = " AND vehicle_type LIKE '%$vehicles%'"; } if ($avail != '') { $sql4 = " AND availability LIKE '%,' $avail% ','"; } if ($price != '') { $sql5 = " AND price_band IN ($price)"; } Can this be done using jquery?

• Wrong label for a nodereference in Drupal content-type

  - by MPD

  We have a content-type built using CCK. One of the fields is a node reference. The node picker is using a view to build the options. A few days ago, everything was working well. Today, it looks like all node reference fields using views to populate the selection options are displaying the wrong label. Every single label in the option is ``A'', but the actual node number is correct. The form actually works, just the labels are incorrect. We have tried just about every combination of edit/save, disable/enable, reboot, clear cache, clone the view, rebuild the view, new view, etc, but we still have a big list of As. If we create a brand new content type with a brand new node reference field, we get the problem. Through some backup/restore exercises, we have determined that the problem is actually in the database and not in the code. We can restore our last good backup, but we will lose a decent amount of work we have put into other parts of the database. We enabled mysql query logging, and the view is actually being called properly, but we cannot track down where the problem is creeping in after that (unraveling the CCK / Views / Drupal plumbing is a challenge). The install was build with latest stable versions as of April. The problems referred to in http://drupal.org/node/624422 is similar, but our code versions include the patches mentioned. Any ideas would be appreciated. Thanks.

• How can I make the storage of C++ lambda objects more efficient?

  - by Peter Ruderman

  I've been thinking about storing C++ lambda's lately. The standard advice you see on the Internet is to store the lambda in a std::function object. However, none of this advice ever considers the storage implications. It occurred to me that there must be some seriously black voodoo going on behind the scenes to make this work. Consider the following class that stores an integer value: class Simple { public: Simple( int value ) { puts( "Constructing simple!" ); this->value = value; } Simple( const Simple& rhs ) { puts( "Copying simple!" ); this->value = rhs.value; } Simple( Simple&& rhs ) { puts( "Moving simple!" ); this->value = rhs.value; } ~Simple() { puts( "Destroying simple!" ); } int Get() const { return this->value; } private: int value; }; Now, consider this simple program: int main() { Simple test( 5 ); std::function<int ()> f = [test] () { return test.Get(); }; printf( "%d\n", f() ); } This is the output I would hope to see from this program: Constructing simple! Copying simple! Moving simple! Destroying simple! 5 Destroying simple! Destroying simple! First, we create the value test. We create a local copy on the stack for the temporary lambda object. We then move the temporary lambda object into memory allocated by std::function. We destroy the temporary lambda. We print our output. We destroy the std::function. And finally, we destroy the test object. Needless to say, this is not what I see. When I compile this on Visual C++ 2010 (release or debug mode), I get this output: Constructing simple! Copying simple! Copying simple! Copying simple! Copying simple! Destroying simple! Destroying simple! Destroying simple! 5 Destroying simple! Destroying simple! Holy crap that's inefficient! Not only did the compiler fail to use my move constructor, but it generated and destroyed two apparently superfluous copies of the lambda during the assignment. So, here finally are the questions: (1) Is all this copying really necessary? (2) Is there some way to coerce the compiler into generating better code? Thanks for reading!

• .htacces Rewrite Rule to Keep .php File Extensions

  - by user2672112

  I'm upgrading my static website that had .php extensions on the content pages. I've created my own simple cms which will start retrieving data from mysql database from now on, keeping the url structure same as the old once. The cms has get function to retrieve url structure from the database. Overall it started working fine with .html when i tested. But when i change the .html extension to .php in my .htaccess code the content pages starts reflecting "Internal Server Error. The server encountered an internal error or misconfiguration and was unable to complete your request." Here is my .htaccess code which i've used: RewriteBase / Options +FollowSymLinks RewriteEngine On RewriteRule ^([^?]*).php$ content.php?pid=$1 Perhaps there is a conflict, here is the code with .html extension that actually works fine. RewriteBase / Options +FollowSymLinks RewriteEngine On RewriteRule ^([^?]*).html$ content.php?pid=$1 So basically, content pages with .html are working & .php are not working. But i need my content pages to be with .php Please help. Thanks in advance... :)

• Doxygen including methods twice doc files

  - by Maarek

  I'm having this issue where doxygen is adding the method twice in the documentation file. Is there a setting that stops auto-generation of documentation for methods within the .m file. For example in the documentation I'll see something like whats below where the first definition of + (Status *)registerUser is from the header XXXXXX.h file where the second is from XXXXXX.m. Header documentation : /** @brief Test Yada Yada @return <#(description)#> */ + (Status *)registerUser; Output: + (Status *) registerUser Test Yada Yada. Returns: <#(description)#> + (Status *) registerUser <#(brief description)#> <#(comprehensive description)#> registerUser Returns: <#(description)#> Definition at line 24 of file XXXXXX.m. Here are the build related configuration options. I've tried playing with them. EXTRACT_ALL with YES and NO... Hiding uncodumented Members and Classes. #--------------------------------------------------------------------------- # Build related configuration options #--------------------------------------------------------------------------- EXTRACT_ALL = NO EXTRACT_PRIVATE = NO EXTRACT_STATIC = NO EXTRACT_LOCAL_CLASSES = YES EXTRACT_LOCAL_METHODS = NO EXTRACT_ANON_NSPACES = NO HIDE_UNDOC_MEMBERS = YES HIDE_UNDOC_CLASSES = YES HIDE_FRIEND_COMPOUNDS = NO HIDE_IN_BODY_DOCS = NO INTERNAL_DOCS = NO CASE_SENSE_NAMES = NO HIDE_SCOPE_NAMES = NO SHOW_INCLUDE_FILES = YES FORCE_LOCAL_INCLUDES = NO INLINE_INFO = YES SORT_MEMBER_DOCS = YES SORT_BRIEF_DOCS = NO SORT_MEMBERS_CTORS_1ST = NO SORT_GROUP_NAMES = NO SORT_BY_SCOPE_NAME = NO

• Codeigniter .htaccess not working in subdirectory

  - by xzdead

  I have this codeingniter project structure webRoot | |/application | | | |/controllers | | | |/admin | |/public | | | |/admin | | | | | |/css | | |/img | |/css | |/img And this is my .htacess file, located in /public. I use this in every local project running xampp: <IfModule mod_rewrite.c> RewriteEngine On RewriteBase / RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^(.*)$ index.php/$1 [L] </IfModule> <IfModule !mod_rewrite.c> # If we don't have mod_rewrite installed, all 404's # can be sent to index.php, and everything works as normal. # Submitted by: ElliotHaughin ErrorDocument 404 /index.php </IfModule> It works fine in localhost, but doesn't work in a dreamhost server. I always get "no input file specified". So after searching the web and trying lots of combinations, the best I got is this .htaccess file: Options +FollowSymLinks RewriteEngine On RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^ index.php [L] With this one, if I go to http://development.mydomain.com - I see the codeigniter welcome page But if I go to: http://development.mydomain.com/admin - I see the directory listing of /public/admin and doesn't execute the controller in /application/controllers/admin Again, if I go to: http://development.mydomain.com/admin/admin - I see the private area, it executes the controller and goes to the default controller defined in routes, "dashboard" This works fine too: http://development.mydomain.com/admin/dashboard I have set in my config file: $config['index_page'] = ''; $config['base_url'] = ''; $config['uri_protocol'] = 'AUTO'; I think that whatever is wrong in my .htaccess is causing other path issues I have with my project. Any help would be great. Thanks to all in advance EDIT: I removed this line: RewriteCond %{REQUEST_FILENAME} !-d because admin directory exists, that's why I see the public directory listing. But now I see the codeigniter welcome page when I go to http://development.mydomain.com/admin So now my .htaccess file looks like: Options +FollowSymLinks RewriteEngine On RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^ index.php [L] #RewriteRule ^(.*)$ /index.php?/$1 [L] I also tried with the commented RewriteRule but I get the same result.

• nullable bool is being passed to the controller null all the time regardless of the value

  - by user1807954

  I'm trying to pass a nullable bool to my controller. But when I pass the bool value from my view to the controller, it's being passed null all the time regardless of the value it has in my view. Here is my view: @model Cars.Models.Car @using (Html.BeginForm("Index", "Home", FormMethod.Post, new { id = "CategoryFormID"})) { <label>Convertible:</label> <input type="checkbox" id="ConvertibleID" name="convertible"/> <button type="submit" name="submit" value="search" id="SubmitID">Search</button> } And my controller: [HttpPost] public ActionResult Index(bool? convertible){ var cars = from d in db.Car select d; if (convertible.HasValue) { cars = cars.Where(x => x.Convertible == convertible); } return View("SearchResult", cars); } I also have other fields such as drop down lists and text fields, but they're being passed flawless. Any help would be really appreciated. Update: Thank you for your fast responds. However, I did try giving it a value="True" as you guys suggested. There is only 2 options now: null and true. But my intention is to use nullable bool to have three options: null (when user doesn't touch the checkbox), true(checked) and false(unchecked). I know it sounds not smart and silly, but I'm just trying to figure out how nullable bool is working, and what is the intention of having such a thing in C# (I'm new with C#). I was wondering if it is possible to do so with just checkbox and without the use of dropdownlist or radio buttons.

• Speed comparison - Template specialization vs. Virtual Function vs. If-Statement

  - by Person

  Just to get it out of the way... Premature optimization is the root of all evil Make use of OOP etc. I understand. Just looking for some advice regarding the speed of certain operations that I can store in my grey matter for future reference. Say you have an Animation class. An animation can be looped (plays over and over) or not looped (plays once), it may have unique frame times or not, etc. Let's say there are 3 of these "either or" attributes. Note that any method of the Animation class will at most check for one of these (i.e. this isn't a case of a giant branch of if-elseif). Here are some options. 1) Give it boolean members for the attributes given above, and use an if statement to check against them when playing the animation to perform the appropriate action. Problem: Conditional checked every single time the animation is played. 2) Make a base animation class, and derive other animations classes such as LoopedAnimation and AnimationUniqueFrames, etc. Problem: Vtable check upon every call to play the animation given that you have something like a vector<Animation>. Also, making a separate class for all of the possible combinations seems code bloaty. 3) Use template specialization, and specialize those functions that depend on those attributes. Like template<bool looped, bool uniqueFrameTimes> class Animation. Problem: The problem with this is that you couldn't just have a vector<Animation> for something's animations. Could also be bloaty. I'm wondering what kind of speed each of these options offer? I'm particularly interested in the 1st and 2nd option because the 3rd doesn't allow one to iterate through a general container of Animations. In short, what is faster - a vtable fetch or a conditional?

• Can JQuery.Validate plugin prevent submission of an Ajax form

  - by berko

  I am using the JQuery form plugin (http://malsup.com/jquery/form/) to handle the ajax submission of a form. I also have JQuery.Validate (http://docs.jquery.com/Plugins/Validation) plugged in for my client side validation. What I am seeing is that the validation fails when I expect it to however it does not stop the form from submitting. When I was using a traditional form (i.e. non-ajax) the validation failing prevented the form for submitting at all.... which is my desired behaviour. I know that the validation is hooked up correctly as the validation messages still appear after the ajax submit has happened. So what I am I missing that is preventing my desired behaviour? Sample code below.... <form id="searchForm" method="post" action="/User/GetDetails"> <input id="username" name="username" type="text" value="user.name" /> <input id="submit" name="submit" type="submit" value="Search" /> </form> <div id="detailsView"> </div> <script type="text/javascript"> var options = { target: '#detailsView' }; $('#searchForm').ajaxForm(options); $('#searchForm').validate({ rules: { username: {required:true}}, messages: { username: {required:"Username is a required field."}} }); </script>

• IE8 ignores jQuery UI 'dialog' minHeight and height settings

  - by Kev

  I'm using jQuery 1.4.4 with jQueryUI 1.8.7 to display a modal dialog box. I'm having a problem where IE8 renders a scrollbar and appears to ignore the minHeight and height options in all the many different combinations I've tried them in. In Chrome 8 and Firefox 3.6 my dialogue looks like: In IE 8 it looks like: The markup and script looks like: <a id="create" href="#">Create New Thing</a> <div id="dlg-create-thing" title="Create new thing?"> <form name="create-thing-form" id="dlg-create-thing-form"> <p style="text-align:left"> <span>Name: <input id="thingName" name="thingName" maxlength="12" size="30" /></span> <br /><br /> <b>Thing options:</b><br /><br /> <input type="radio" id="option1" name="theoptions" value="0" checked="checked" />Use this option<br /> <input type="radio" id="option1AndMem" name="theoptions" value="1" />Use this other option </p> </form> </div> <script type="text/javascript"> $(function () { $("#dlg-create-thing").dialog({ autoOpen: false, resizable: false, width: 500, modal: true, minHeight: 280, buttons: { "Create": function () { /* do stuff */ }, "Cancel": function () { /* do other stuff */} } }); $("body").delegate("a[id='create']", "click", function () { $("#dlg-create-thing").dialog('open'); return false; } ); }); </script> How can I fix this (preferably in a nice browser agnostic way, but I'd settle for anything)?

• C Language preprocessing doubt

  - by khanna_param

  Hi, There are different kind of macros in C language, nested macro is one of them. Considering a program with the following macro define HYPE(x,y) (SQUR(x)+SQUR(y)) define SQUR(x) (x*x) using this we can successfully complile to get the result. My question:- As we all know the C preprocessor replaces all the occurrence of the identifiers with the replacement-string. Considering the above example i would like to know how many times the C compiler traverses the program to replace the macro with the replacement values. I assume it cannot be done in one go. Thanks.

• RadioGroup onCheckedChanged function won't fire

  - by user1758088

  First time/long time. My app keeps track of restaurant servers' shift sales to help them budget. In the activity that displays past shifts, I've created a RadioGroup under the ListView so the server can choose lunch, dinner, or both. I've implemented RadioGroup.onCheckedChangeListener, but onCheckChanged never gets called. I also tried an anonymous inner class as listener, same result. I tried to copy/modify code from this answer: http://stackoverflow.com/a/9595528 ...but when I added the @Override to the callback function, the Eclipse compiler gave me an error (not warning) that the method must override a superclass, and the quick fix was to remove the override. I'm pretty sure the signatures are correct, as they were made with Eclipse's autocomplete and implement methods facilities. I then followed instructions to move my java compiler from 1.5 to 1.6, and none of the above listed behavior seemed to change. Here's the code I thing is relavent: public class DataActivity extends ListActivity implements OnCheckedChangeListener{ RadioButton rbBoth; RadioButton rbDinnerOnly; RadioButton rbLunchOnly; @Override public void onCreate(Bundle savedInstanceState){ super.onCreate(savedInstanceState); setContentView(R.layout.database); ... final RadioGroup rgGroup = (RadioGroup)findViewById(R.id.DataRadioGroup); rbBoth = (RadioButton)findViewById(R.id.RadioBoth); rbDinnerOnly = (RadioButton)findViewById(R.id.RadioDinnerOnly); rbLunchOnly = (RadioButton)findViewById(R.id.RadioLunchOnly); rgGroup.setOnCheckedChangeListener(this); populateAllShifts(); } ... public void onCheckedChanged(RadioGroup group, int checkedId) { rbLunchOnly.setText("Click!"); Toast.makeText(getApplicationContext(), "Lunch Only", Toast.LENGTH_LONG).show(); if(group.getCheckedRadioButtonId() == R.id.RadioBoth){ populateAllShifts(); return; } if(group.getCheckedRadioButtonId() == R.id.RadioLunchOnly){ populatLunchShifts(); return; } if(group.getCheckedRadioButtonId() == R.id.RadioDinnerOnly){ populateDinnerShifts(); return; } } There is a ListView in this class with a custom adapter, but if my understanding and my XML are correct, the RadioGroup should be outside of the list: <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/llDataLayout" android:weightSum="5" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical"> <ListView android:layout_weight="4" android:layout_width="fill_parent" android:id="@android:id/list" android:layout_height="wrap_content"></ListView> <RadioGroup android:layout_weight="1" android:id="@+id/DataRadioGroup" android:orientation="horizontal" android:layout_height="wrap_content" android:layout_width="fill_parent"> <RadioButton android:text="Lunch and Dinner" android:textSize="10dp" android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="@+id/RadioBoth"/> <RadioButton android:text="Dinner Only" android:textSize="10dp" android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="@+id/RadioDinnerOnly"/> <RadioButton android:text="Lunch Only" android:textSize="10dp" android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="@+id/RadioLunchOnly"/> </RadioGroup> </LinearLayout> Any ideas out there?

• c++ protected pointer member to the same class and access privileges

  - by aajmakin

  Hi, Example code is included at the bottom of the message. I'm puzzled about the protected access specifier in a class. I have define a class node which has a protected string member name string name; and a vector of node pointers vector args; Before I thought that a member function of node could not do args[0]-name but a program that does just this does compile and run. However, now I would like to inherit this class and access the name field in one of the args array pointers from this derived class args[0]-name but this does not compile. When I compile the example code below with the commented sections uncommented, the compiler reports: Compiler output: g++ test.cc -o test test.cc: In member function 'void foo::newnode::print_args2()': test.cc:22: error: 'std::string foo::node::name' is protected test.cc:61: error: within this context Compilation exited abnormally with code 1 at Thu Jun 17 12:40:12 Questions: Why can I access the name field of the node pointers in args in class node, because this is what I would excpect from a similarly defined private field in Java. How can I access those fields from the derived class. Example code: #include <iostream> #include <vector> using namespace std; namespace foo { class node; typedef std::vector<node*> nodes; class node { public: node (string _name); void print_args (); void add_node (node* a); protected: nodes args; string name; }; } foo::node::node (string _name) : args(0) { name = _name; } void foo::node::add_node (node* a) { args.push_back(a); } void foo::node::print_args () { for (int i = 0; i < args.size(); i++) { cout << "node " << i << ": " << args[i]->name << endl; } } // namespace foo // { // class newnode : public node // { // public: // newnode (string _name) : node(_name) {} // void print_args2 (); // protected: // }; // } // void foo::newnode::print_args2 () // { // for (int i = 0; i < args.size(); i++) // { // cout << "node " << i << ": " << args[i]->name << endl; // } // } int main (int argc, char** argv) { foo::node a ("a"); foo::node b ("b"); foo::node c ("c"); a.add_node (&b); a.add_node (&c); a.print_args (); // foo::newnode newa ("newa"); // foo::newnode newb ("newb"); // foo::newnode newc ("newc"); // newa.add_node (&newb); // newa.add_node (&newc); // newa.print_args2 (); return 0; }

• Can anyone recommend a payment processing script or service that is as (nearly?) as convenient and c

  - by Jason Livesay

  I have been going through all of the different PayPal integration options and trying to decide which will be the best one for this particular application. I realized that I really want to give users a few options for payment. For example, it might be more convenient to enter their credit card information rather than being sent over to PayPal, or they may have already setup their Google Checkout and so want to use that. So that brings me fairly quickly to the realization that maybe I don't want to program one or two or three API integrations myself and I should look at some shopping cart software. However, we really don't need a whole shopping cart -- we will have a specific form and some other custom coding and the only part of the shopping cart we would really use would be the checkout page to handle accepting payment/integrating with PayPal/Google Checkout/Authorize.net. I like how simple eJunkie makes things and the fact that it accepts PayPal and Google Checkout and Authorize.net. The problem is that the Add To Cart buttons aren't going to cut it. I need to be able to programmatically enter items into the cart. Maybe I can just use an open source PHP shopping cart and skip the store front somehow.

• How would I include open source library in my iPhone application?

  - by greypoint

  I have found an existing open source library that I would like to include in my iPhone project (the unrar source code found here: http://www.rarlab.com/rar_add.htm ). I have compiled this source as a linked library on my Mac with "make lib" which creates the libunrar.so file just fine. These are the makefile settings for that target: lib: WHAT=RARDLL lib: $(OBJECTS) $(LIB_OBJ) @rm -f libunrar.so $(LINK) -shared -o libunrar.so $(LDFLAGS) $(OBJECTS) $(LIB_OBJ) Obviously I can't use this on iPhone but I imagine I should be able to compile with different options to make a static library that I can use. Do I: Compile it on the Mac with different make options then drag the resulting library (some kind of .a ?) into my xcode project? or Drag all of the source code into my xcode project and create special targets of some kind to create it? or Something else entirely different? I've been working on solving my unrar problem for a couple of weeks now and I believe using this library will give me the best results but I just don't know the final steps to make use of it. Thanks for all advice.

• Issue with the Entity Manager and phpunit in Symfony 2

  - by rgazelot

  I have an issue with my Entity Manager in phpunit. This is my test : public function testValidChangeEmail() { $client = self::createAuthClient('user','password'); $crawler = $client->request('GET', '/user/edit/30'); $crawler = $client->submit($crawler->selectButton('submit')->form(array( 'form[email]' => '[email protected]', ))); /* * With this em, this work perfectly * $em = $client->getContainer()->get('doctrine.orm.entity_manager'); */ $user = self::$em->getRepository('MyBundle:User')->findUser('[email protected]'); die(var_dump($user->getEmail())); } and this is my WebTestCase which extends original WebTestCase : class WebTestCase extends BaseWebTestCase { static protected $container; static protected $em; static protected function createClient(array $options = array(), array $server = array()) { $client = parent::createClient($options, $server); self::$em = $client->getContainer()->get('doctrine.orm.entity_manager'); self::$container = $client->getContainer(); return $client; } protected function createAuthClient($user, $pass) { return self::createClient(array(), array( 'PHP_AUTH_USER' => $user, 'PHP_AUTH_PW' => $pass, )); } As you can see, I replace the self::$em when I created my client. My issue : In my test, the die() give me the old email and not the new email ([email protected]) which has registered in the test. However in my database, I have the [email protected] correctly saved. When I retrieve my user in the database, I use sefl::$em. If I use the $em in comments, I retrieve the right new email. I don't understand why in my WebTestCase, I can access to the new Entity Manager...

• Show only div of the product hovering in category grid with jQuery

  - by Dane

  On Magento, I'm trying to get avalable attributes per product in a new div (show/ hide onmouseover) as soon as I hover a product. Unfortunately, my jQuery code opens every div with the same name. I think, I need to do it with jQuery(this) but I tried it in a 1000 different ways, and it won't work. Maybe, somebody here can help me with a better code. jQuery(function() { jQuery('.slideDiv').hide().data('over', false); jQuery('#hover').hover(function() { jQuery('.slideDiv').fadeIn(); }, function() { // Check if mouse did not go over .dialog before hiding it again var timeOut = setTimeout(function() { if (!jQuery('.slideDiv').data('over')) { jQuery('.slideDiv').fadeOut(); clearTimeout(timeOut); } }, 100); }); // Set data for filtering on mouse events for #hover-here jQuery('.slideDiv').hover(function() { jQuery(this).data('over', true); }, function() { jQuery(this).fadeOut().data('over', false); }); }); The PHP just prints the attributes needed. <a href="#" id="hover">Custom Attributes</a> <div class="slideDiv"> <?php $attrs = $_product->getTypeInstance(true)->getConfigurableAttributesAsArray($_product); foreach($attrs as $attr) { if(0 == strcmp("shoe_size", $attr['attribute_code'])) { $options = $attr['values']; print "Größen:<br />"; foreach($options as $option) { print "{$option['store_label']}<br />"; } } } ?> </div> I added the script to [new link] http://jsfiddle.net/xsxfr/47/ so you can see there, that it is not working like this right now :(.

• Have ASP page call save function anytime the user tries to navigate away from page

  - by Breander

  What I have is an input page with a bunch of dynamically created textboxes for the user to input data. The textboxes are dynamically created because the number that are needed are not known until the user selects some options on the page. So what I need to have happen is if the user tries to either A) navigate away from the page or B) select different options bringing up new textboxes. Anything the user may have typed into the textboxes needs to automatically be saved to the database. Like they clicked on the save button on the page. This doesn't sound like a vary smart way to do things or even an easy way to do things but this is the requirement I have been given. No message just save to the database. I have looked into things like onbeforepageunload javascript but that mostly tries to stop the user from navigating away I can't call any code behind code from it. Any help is appreciated. Note : The number of the texboxes with data can be any where between 20 and 500. Yes very crazy but not my idea.

• Alternate colors on click with jQuery

  - by Jace Cotton

  I'm sure there is a simple solution to this, and I'm sure this is a duplicate question, though I have been unable to solve my solution particularly because I don't really know how to phrase it in order to search for other questions/solutions, so I'm coming here hoping for some help. Basically, I have spans with classes that assigns a background-color property, and inside those spans are words. I have three of these spans, and each time a user clicks on a span I want the class to change (thus changing the background color and inner text). HTML: <span class="alternate"> <span class="blue showing">Lorem</span> <span class="green">Ipsum</span> <span class="red">Dolor</span> </span> CSS: .alternate span { display : none } .alternate .showing { display : inline } .blue { background : blue } .green { background : green } .red { background : red } jQuery: $(".alternate span").each(function() { $(this).on("click", function() { $(this).removeClass("showing"); $(this).next().addClass("showing"); }); }); This solution works great using $.next until I get to the third click, whereafter .showing is removed, and is not added since there are no more $.next options. How do I, after getting to the last-child, add .showing to the first-child and then start over? I have tried various options including if($(".alternate span:last-child").hasClass("showing")) { etc. etc. }, and I attempted to use an array and for loop though I failed to make it work. Newb question, I know, but I can't seem to solve this so as a last resort I'm coming here.

• WP7 help with menu effects

  - by MattMacdonald

  Kinda new to Silverlight and have some experience with WPF but I'm doing a project with a group for a class making a game for WP7. I am currently in charge of the menu system for the game and I had a few ideas for "flashy" menu transitions. I got some going for the main menu but I wanted to do something cool for the options submenu. Anyway my idea is to either fashion an expander or to have sort of a variation of a dialog box. But the way I envisioned it would be in either case the menu items blur but are still visible while the expanded menu is displayed or while the dialog is active. If I'm being confusing sorry :) but think of Windows 7 glass effect on the menu while other options are available. What I'm getting at is I want to give this a shot but I have no idea how I would go about doing something like this. Could anyone point me in the right direction or outline some key steps for me to build off? I tried finding something like this on Google but no such luck.

• JavaCard monitoring folder

  - by GxG

  I want to write a two way application: applet for javacard and an application in C#. I've got the C# covered but i want to know if with JavaCard i can monitor a folder on the memory and how would i go about doing that. I have a shared folder let's call it temp in which i want to store buffer information between the simulated smartcard and the C# application. The C# application will only read from that folder and display the information, but also it will write requests towards the smartcard. For example i simulate entering the PIN for the card. The applet will write a file containing available options and the C# application will read that file and display those options; from the C# app i will chose and option and write a request file in the same folder. This is when the smartcard which is monitoring that folder will read the request and issue a response. Can i make the smartcard monitor that folder? I was thinking of using encrypted XML files for the request/response operations. But simple .txt files are good to. I am limited to using JavaCard v2.2.1, and every operation has to be encrypted/decrypted. (with the ciphering i have no problem)

• How can flash call jquery function in its event

  - by user2955639

  I want jquery to do something during some of the events when an audio is playing. So I'm coding a function like this <script> $.fn.playMedia = function(options){ var opts = $.extend({}, { swfSrc: '' timeUpdated: function(currentTime){}, startPlay: function(){}, endPlay: function(){} }, options); return $(this).each(function(){ // call flash to play the media whose src is opts.swfSrc // Is it possible that flash can call the js functions(opts.timeUpdate, opts.startPlay and opts.endPlay) at each time of the event is triggered? }); }}; </script> // Usage <div id="player"></div> <script> $('#player').playMedia({ swfSrc: '/path/song.mp3', timeUpdated: function(currentTime){ comsole.log(currentTime); } }); </script> I'm a totally layman of flash, I just guess this works. Hope someone could tell me how to make up a swf file for this jquery function. Or is there any existing jquery plugin which does this thing but can re-design apperance flexibly. Thank you very much!

• Unexpected token ILLEGAL with jQuery

  - by Bram Vanroy

  So, I have a website with an autoFontSize script (Got it from stackoverflow, but slightly edited it too loop over each div with that specific class) (function ($) { $.fn.textfill = function (options) { this.each(function () { var fontSize = options.maxFontPixels; var ourText = $('h2 a', this); var maxHeight = $(this).height(); var maxWidth = $(this).width(); var textHeight; var textWidth; do { ourText.css('font-size', fontSize); textHeight = ourText.height(); textWidth = ourText.width(); fontSize = fontSize - 1; } while ((textHeight > maxHeight || textWidth > maxWidth) && fontSize > 16); }); return this; }; })(jQuery); $(document).ready(function () { $('.fotonode.fotopagina').textfill({ maxFontPixels: 30 }); });? And a (simplified) HTML structure: <div class="fotonode fotopagina"> <h2><a href="#">Testing Title</a></h2> </div> For some reason this doesn't work (neither locally nor live) BUT it does work on JSfiddle: http://jsfiddle.net/Yb9yj/ I read somewhere that this can cause problems. I copied the code from jsfiddle to my file, so maybe I have (unintentionally) copied some white spaces that shouldn't be there or something. I don't know. But how can I solve this then?
