• Remote connect to mysql?

  - by chobo2

  Hi I don't use php or mysql but I am trying to upgrade a phpbb board I got but the one click installer forgot to install some stuff in the database so I can't upgrade to the newest version till I add the missing stuff. So I need to do a remote connect to mysql database but I am not sure how to do this or what software I need(free, and very easy to setup I don't want to spend much time on this). I don't really want to use phpmyadmin since I don't want to start setting up a virtual directory and whatever else it needs to be installed. Like I said I don't do php or mysql I just choose it since in my hosting package it was one click to install phpbb and I had a mysql database free. Thanks

• Converting files to blob to save in database

  - by jimbo

  I have an old user site that we are currently updating. The site's users have previously uploaded profile pics that are stored in a directory. I am now wanting to keep these profile images in the database, (easy to backup all data) but am having trouble working out how to do it. There are a lot of tutorials talking about do ing this from files that have just been uploaded and using the tmp name etc, but how can I re-create with files that have already been uploaded? I have looked into $data = file_get_contents($filename); Which seems to create a binary file, but doesn't seem to save in database with: mysql_query("UPDATE profiles SET company_logo = mysql_real_escape_string('".$data."') WHERE id = 1 ") or die(mysql_error());

• problem with live function

  - by Dirty Bird Design

  I had this working to spec, until the specs changed. This function is now brought in via ajax .load. Easy enough to bring it in and I have all my other functions on the page that is brought in working in the parent page except this one: $("#CME").hide(); $(function() { $("#CME1, #CMEQL, #CBT1, #CBTQL, #NYM1, #CMX1").live("change", function(){ var checkBoxes = $("#CME1, #CMEQL, #CBT1, #CBTQL, #NYM1, #CMX1").filter(":not(:checked)"); if(checkBoxes.length == 0){ $("#CME").slideDown("fast"); } else { $("#CME").slideUp("fast"); } }); the div "#CME" is not hidden and the .live('change', function () { isn't working. I have other similar .live functions that are working and structured the same. How do I bind the initial $(function() with .live and why isn't the .hide() working? });//CME

• Showing and hidding a DIV

  - by user1741568

  I'm in the process of building a gallery for my public art pieces. I was wondering if there was an easy way to show and hide a div? I only want the concept text to be seen on the first page of the following link: http://www.gerardtonti.com/PresentTense/PresentTense.html Right now I have the concept in a div called "concept" set to absolute positioning. Is there also a way for the text to conform relative to the size of the window like the background image? I've also tried using an iframe and colorbox instead of a div but had no idea how to make the iframe visible only on the first slide as well. Wether using an iframe or div, I was wondering if it was possible to hide either on the frames that follow the first slide. Any help would be greatly appreciated. Thank you, Gerry

• collapsing a UITableView

  - by Sage Washabaugh

  Hey everyone I made a UITableView in my app and when a cell is touched it expands the problem I am having is it does not collapse no matter what I have tried, I'm sure its something easy i just cant figure it out the only time it does collapse is when it another cell is tapped.

• Replace an element name while retaining the attributes with jquery

  - by geckomist

  I'm trying to create a jquery setup where all instances of <i> are changed to <em>. It's easy enough to do with: $("i").each(function(){ $(this).replaceWith($('<em>' + this.innerHTML + '</em>')); }); But what I am having trouble figuring out is how to change all the <i> tags but retain each ones individual attributes. So if I have <i style="background-color: #333;" alt="Example" title="Example">Example Text</i> I would like it to change to <em style="background-color: #333;" alt="Example" title="Example">Example Text</em> Thanks for any help!

• Any dynamic database frontend tool from which you can update directly?

  - by Enjoy coding

  Hi Gurus, This is with reference to this question where I got one tabular report format. I need to update the user entered values correctly back to the same table rows. I am in the process of doing this by using general form post data methods by using some logics which I think will not be easy to maintain. So, just out of curiosity, Is there a front end creator javascript libraries or frameworks which can create the front end for any query's resultset and updates the corresponding rows when the user updates them from front end. This need not have all the full functionality, any one usable, customizable thing will reduce the code maintenance problems. I have googled for some javascript libraris for this but not able to get which will be suitable. Please suggest any useful tools. My environment is Mysql, PHP, JQuery, XAMPP server on Windows. Is JQuery provides one. Thanks in advance.

• Is there anything wrong with taking immediate actions in constructors?

  - by pestaa

  I have classes like this one: class SomeObject { public function __construct($param1, $param2) { $this->process($param1, $param2); } ... } So I can instantly "call" it as some sort of global function just like new SomeObject($arg1, $arg2); which has the benefits of staying concise, being easy to understand, but might break unwritten rules of semantics by not waiting till a method is called. Should I continue to feel bad because of a bad practice, or there's really nothing to worry about? Clarification: I do want an instance of the class. I do use internal methods of the class only. I initialize the object in the constructor, but call the "important" action-taker methods too. I am selfish in the light of these sentences.

• Where do I put my php files to have Xampp parse them?

  - by CDeanMartin

  I finished installing Ubuntu 10 for netbooks, and XAMPP. The XAMPP website tutorial made it very easy to install, then left me high and dry. Everything works, but I have no idea where to put my handwritten php files. After a few hours of googling, and trying to understand the file explorer, I realized I have no idea where anything is in ubuntu. For an answer, please don't just tell me "go to "X" directory. I won't know how to navigate there. I also did a file search for htdocs with no luck.

• Simple php statement, I can't get it to work!

  How to get $schedule = true and $schedule = true to work??? I know this is easy and I'm overlooking something simple! else { if($schedule){ $where[] = 'date > '.(time() + $config_date_adjust * 60 - 432000); } else{ $where[] = 'date < '.(time() + $config_date_adjust * 60); } $schedule = false; } else { if($schedule2){ $where[] = 'date > '.(time() + $config_date_adjust * 60 - 86400); } else{ $where[] = 'date < '.(time() + $config_date_adjust * 60); } $schedule2 = false; }

• Dynamic SQL Rows & Columns...cells require subsequent query. Best approach?

  - by Pyrrhonist

  I have the following tables below City --------- CityID StateID Name Description Reports --------- ReportID HeaderID FooterID Description I’m trying to generate a grid for use in a .Net control (Gridview, Listview…separate issue about which will be the ‘best’ one to use for my purposes) which will assign the reports as the columns and the cities as the rows. Which cities get displayed is based on the state selected, and is easy enough SELECT * FROM CITIES WHERE STATEID=@StateID However, the user is able to select which reports are being generated for each City (Demographics, Sales, Land Area, etc.). Further, the resultant cells (City * Report) is a sub-query on different tables based on the city selected and the report. Ie. Column Sales selected yields SELECT * FROM SALES WHERE CITYID=@CityID I’ve programmed a VERY inelegant solution using multiple queries and brute-forcing the grid to be created (line by line, row by row creation of data elements), but I’m positive there’s got to be a better way of accomplishing this…? Any / all suggestions appreciated here as the brute force approach I’ve gotten is slow and cumbersome…and this will have to be used often by the client, so I’m not sure it’ll be acceptable in it’s current implementation.

• Rendering field data as a link in Ruby on Rails...

  - by bgadoci

  Ok, I think this is probably an easy question but for the life of my I can't figure it out. I have created a table called ugtags and in that table I have two columns (beyond the basics), 'name' and 'link'. I am trying to allow a user to add a link to a page. Ideally they would enter the link title (name) and the url (link) and in the view it would display the title as a link to the url that was entered in the link column. I there a way to do it by simply affecting the <%= link_to h(ugtag.name) %> code?

• Disallow typing of few of characters e.g.'<', '>' in all input textboxes using jquery

  - by Ismail

  How do I achieve this:- When user types character like 'abcd' and then '>'(an invalid character for my application), I want to set the text back to 'abcd'. Better if we can cancel the input itself as we do in winforms application. This should happen when user is typing and not on a click of button. I want this to be applied on all text boxes in my web page. This will be easy if the solution is jQuery based. May be something which will start like this. $("input[type='text']")

• Is there any declare for toggle() that if its open do this, closed to that?

  - by Dejan.S

  Im doing some jquery stuff with toggle(), I'm doing different actions depending on if the current div is closing or showing, i know i can easy check if a div hasClass() or is(':visible') for what i want to do, but I'm thinking maybe there is somehow that i can reduce the amount of code or just do it more efficient? like declare the toggle() with two functions that this is for when its showing and this is for when its closing, is this possible? hope you get what i mean? like this, or check a jsfiddle $('#click_me').on('click', function() { $('#contain').toogle('blind', 300, function (){ alert('open'); }, function (){ alert('close'); }); });

• Is there a point creating a site using XSLT

  - by webwise

  Is this technology still popular? I want to make a website which automatically transforms XSLT files. It should work like this: When a user accesses the site, a single handler would accept his request and then find a suitable XML for it (according to the URL requested) and transform it using its attached XSL file. I want to do this in order to make it easy to update the site using plain XML files (instead of using a full-fledged & expensive CMS system). What do you say? good idea? bad idea? anyone has a recommendation? Thanks!

• How to make a div float in and scroll with the center of page?

  - by Murvinlai

  So, I work on a Facebook FBML App. What I want is simple. Just have a div shows in the center of the page, and scroll with the page. i.e. always in the center. It would be easy with normal JS. I just use the pageYOffset However, in Facebook using FBJS, I am not sure what I should use. It doesn't have getPageYOffset().. and I tried getScrollTop().. it doesn't seem the right thing. So, anyone knows how?

• db optimization - have a total field or query table?

  - by Dorian Fife

  I have an app where users get points for actions they perform - either 1 point for an easy action or 2 for a difficult one. I wish to display to the user the total number of points he got in my app and the points obtained this week (since Monday at midnight). I have a table that records all actions, along with their time and number of points. I have two alternatives and I'm not sure which is better: Every time the user sees the report perform a query and sum the points the user got Add two fields to each user that records the number of points obtained so far (total and weekly). The weekly points value will be set to 0 every Monday at midnight. The first option is easier, but I'm afraid that as I'll get many users and actions queries will take a long time. The second option bares the risk of inconsistency between the table of actions and the summary values. I'm very interested in what you think is the best alternative here. Thanks, Dorian

• Get PropertyInfo from property instead of name

  - by Sam

  Say, for example, I've got this simple class: public class MyClass { public String MyProperty { get; set; } } The way to get the PropertyInfo for MyProperty would be: typeof(MyClass).GetProperty("MyProperty"); This sucks! Why? Easy: it will break as soon as I change the Name of the Property, it needs a lot of dedicated tests to find every location where a property is used like this, refactoring and usage trees are unable to find these kinds of access. Ain't there any way to properly access a property? Something, that is validated on compile time? I'd love a command like this: propertyof(MyClass.MyProperty);

• MySQL sorting: NULL to the end & use index? Not possible?

  - by Vojto

  Hello fellow experts, I have a huge table and I want simple sorting. It could be so easy. I could just create an index and do some really fast sorting thanks to that index. But my client wants to put NULLs to the end, which is complicates the whole situation. Instead of simple: SORT BY name ASC I have to do SORT BY name IS NULL ASC, name ASC. That would be ok, but it because of that my index is useless, and the sorting is very slow. I don't know if there's a way to solve this problem, but if there is one, I desperately ask for help. :'(

• How to call a function from a shared library?

  - by Frank

  What is the easiest and safest way to call a function from a shared library / dll? I am mostly interested in doing this on linux, but it would be better if there were a platform-independent way. Could someone provide example code to show how to make the following work, where the user has compiled his own version of foo into a shared library? // function prototype, implementation loaded at runtime: std::string foo(const std::string); int main(int argc, char** argv) { LoadLibrary(argv[1]); // loads library implementing foo std::cout << "Result: " << foo("test"); return 0; } BTW, I know how to compile the shared lib (foo.so), I just need to know an easy way to load it at runtime.

• How to get the app a Django model is from?

  - by e-satis

  I have a model with a generic relation: TrackedItem --- genericrelation ---> any model I would like to be able to generically get, from the initial model, the tracked item. I should be able to do it on any model without modifying it. To do that I need to get the content type and the object id. Getting the object id is easy since I have the model instance, but getting the content type is not: ContentType.object.filter requires the model (which is just content_object.__class__.__name__) and the app_label. I have no idea of how to get in a reliable way the app in which a model is. For now I do app = content_object.__module__.split(".")[0], but it doesn't work with django contrib apps.
