  • Generate switch cases in php from an array?

    - by mopsyd
    Is it possible to generate the cases for a switch in php using an array? Something like: $x=array( 0 => 'foo', 1 => 'bar', 2 => 'foobar' ); $y='foobar' switch($y) { foreach($x as $i) { case $x: print 'Variable $y tripped switch: '.$i.'<br>'; break; } } I would like to be able to pull the case values from a database and loop through them with a while() loop.

  • the use of private keyword

    - by LAT
    Hi everyone I am new to programming. I am learning Java now, there is something I am not really sure, that the use of private. Why programmer set the variable as private then write , getter and setter to access it. Why not put everything in public since we use it anyway. public class BadOO { public int size; public int weight; ... } public class ExploitBadOO { public static void main (String [] args) { BadOO b = new BadOO(); b.size = -5; // Legal but bad!! } } I found some code like this, and i saw the comment legal but bad. I don't understand why, please explain me.

  • android: getting rid of "warning: unmappable character for encoding ascii"

    - by Lo'oris
    I'm compiling using android tools without eclipse. I compile launching "ant debug" from command line. I have found many many instructions around the web about how to remove with annoying warning, but I haven't been able to make any of them work. I've tried -D option, I've tried randomly tweaking build.* files, I've tried exporting an environment variable... nothing. I guess some of these methods just don't work, and some others would work but I've been doing them incorrectly. Anything is possible and I can't stand it any more: any advice on how to do it?

  • addslashes and addcslahes

    - by theband
    I was seeing today the addslashes and addcslashes in php.net, but did not get the point on what is the difference between them and what are the characters escaped in these two. <?php $originaltext = 'This text does NOT contain \\n a new-line!'; $encoded = addcslashes($originaltext, '\\'); $decoded = stripcslashes($encoded); //$decoded now contains a copy of $originaltext with perfect integrity echo $decoded; //Display the sentence with it's literal \n intact ?> If i comment the $decoded variable and echo $encoded, i get the same value which is in the original string. Can anyone clearly explain me the difference and use of these two.

  • [MAC] Using a proxy for NSURLConnection

    - by SideSwipe
    Is there any way to get the content of a webfile (namely a .html Document) using a proxy, which is not defined in the system settings? I know that NSURLConnection is the right way to download a web file into a variable and not into a file (for which we should use NSURLDownload), but I don't find an way to use a proxy for it. Are there some inofficial APIs, Librarys or Classes or such I could use for what I want to do? I'm not that pro in Mac Programming, so im searching for something more or less simple to do for me plz.

  • that, self or me — which one to prefer in JavaScript?

    - by Török Gábor
    While coding JavaScript sometimes you store the reference of object this in a local variable for different purposes (to set proper scope, to help code obfuscators, etc.). There are coders who prefer aliasing this to that to make it obvious its intention. Other guys use self since it's pointing to the object itself. I even saw source codes where me held the reference and it still makes sense. Certainly there are other ones. Which one should I prefer? Is there a convention on which to use or is it only the matter of taste.

  • PhotobucketNet photo upload

    - by n1tr0
    I have a problem with PhotobucketNet user login(I need user to login so I can upload a picture from HDD to his Photobucket account). Photobucket photobucket = new Photobucket("myapikey", "myapisecret"); photobucket.LaunchUserLogin(); // the problem happens here photobucket.RequestUserToken(); If I call RequestUserToken() it will happen immediately, so I'll get a crash cause user didn't logged in, and there is no event that's been raised after user logs in. Is there some variable(bool or something else) that I can check to see if user logged in - maybe to put it in a loop with timer? Also is their a way to know if user canceled logging in? I know that timer isn't a good solution, so if anyone has anything better as an idea, I'm open for any suggestions...

  • How to suppress a MongoDDException when proxy can't find a referenced document

    - by Madarco
    We are using Symfony2/DoctrineOdm/MongoDB and when we do: if ($doc.referenceOne != null) { ... } and the $doc.referenceOne contains a MongoDbRef that point to a deleted/lost document, the Doctrine Proxy object raises a MongoDBException. It is possible to tell the Proxy return null instead of raising the exception? Detailed Explanation: Our document: class User { /* @MongoDB\ReferenceOne( ... ) */ private $photo; } If $photo contains a MongoDbRef, but the document is lost/deleted, when we do if ($user.photo) { ... } doctrine will raise a MongoDBException: The "Proxies\DocumentPhotoProxy" document with identifier "4fd8b3ef732bafab7b000000" could not be found We want to suppress the exception since our application can handle null values in that variable. (we could simply log that error, while the exception propagate to a 500 page and disrupt our service)

  • Should member variables of global objects be made global as well?

    - by David Wong
    I'm developing plugins in Eclipse which mandates the use of singleton pattern for the Plugin class in order to access the runtime plugin. The class holds references to objects such as Configuration and Resources. In Eclipse 3.0 plug-in runtime objects are not globally managed and so are not generically accessible. Rather, each plug-in is free to declare API which exposes the plug-in runtime object (e.g., MyPlugin.getInstance() In order for the other components of my system to access these objects, I have to do the following: MyPlugin.getInstance().getConfig().getValue(MyPlugin.CONFIGKEY_SOMEPARAMETER); , which is overly verbose IMO. Since MyPlugin provides global access, wouldn't it be easier for me to just provide global access to the objects it manages as well? MyConfig.getValue(MyPlugin.CONFIGKEY_SOMEPARAMETER); Any thoughts? (I'm actually asking because I was reading about the whole "Global variable access and singletons are evil" debates)

  • Constant Assigment Bug in Ruby?

    - by aronchick
    We caught some code in Ruby that seems odd, and I was wondering if someone could explain it: $ irb irb(main):001:0> APPLE = 'aaa' => "aaa" irb(main):002:0> banana = APPLE => "aaa" irb(main):003:0> banana << 'bbb' => "aaabbb" irb(main):004:0> banana => "aaabbb" irb(main):005:0> APPLE => "aaabbb" Catch that? The constant was appended to at the same time the local variable was. Known behavior? Expected?

  • How do I replace "this" in Java with something that works.

    - by Luke Alderton
    I'm looking to get the showGUI() method work, the compiler says "this" is not a static variable and cannot be referenced from a static context, what would I use to replace "this"? I've tried test.main (test being the package it's in). The reason I'm using the static method showGUI() is because I need the method to be called from another static method, as well as the startup() method. Below are my two main classes. public class Main extends SingleFrameApplication { @Override protected void startup() { showGUI(); } @Override protected void configureWindow(java.awt.Window root) { } public static Main getApplication() { return Application.getInstance(Main.class); } public static void main(String[] args) { launch(Main.class, args); } public static void showGUI() { show(new GUI(this)); } } public class GUI extends FrameView { public GUI(SingleFrameApplication app) { super(app); initComponents(); } private void initComponents() { //all the GUI stuff is somehow defined here } }

  • what's called after returning from presentModalViewController / dismissModalViewControllerAnimated:

    - by Reinhard
    to show a modal uiview out of my mainView I use: [self presentModalViewController:myController animated:YES]; and in MyController I close that view with: [self dismissModalViewControllerAnimated:YES]; But how can I know in the mainView that the modal was finished (to redraw my table)? Currently I set a local variable to YES in my mainView after starting the modal view an react on viewWillAppear: [self presentModalViewController:myController animated:YES]; _reloadTableData = YES; -(void)viewWillAppear:(BOOL)animated { [super viewWillAppear:animated]; if (_reloadTableData) { _reloadTableData = NO; [_tableView reloadData]; } } Is there a better way to do so ?

  • How to code the set method of a Map with another Map as value?

    - by Nazgulled
    I normally do this to set a new Map to a private variable: public static void setListaClausulas(Map<String, Clausula> nvLista) { listaClausulas = new TreeMap<String, Clausula>(nvLista); } I suppose this is ok to set a new copy of the nvLista and all it's members and not a reference, is it? But now I have a Map inside another Map and I'm doing this: public static void setListaClausulas(Map<String, Map<String, Clausula>> nvLista) { listaClausulas = new TreeMap<String, Map<String, Clausula>>(nvLista); } Is this the correct way to do it or do you recommend something else? What I want is to set a new copy of nvLista (and all it's elements) and not copy just the reference.

  • How do you extend a Ruby module with macro-like metaprogramming methods?

    - by Ian Terrell
    Consider the following extension (the pattern popularized by several Rails plugins over the years): module Extension def self.included(recipient) recipient.extend ClassMethods recipient.class_eval { include InstanceMethods } end module ClassMethods def macro_method puts "Called macro_method within #{self.name}" end end module InstanceMethods def instance_method puts "Called instance_method within #{self.object_id}" end end end If you wished to expose this to every class, you can do the following: Object.send :include, Extension Now you can define any class and use the macro method: class FooClass macro_method end #=> Called macro_method within FooClass And instances can use the instance methods: FooClass.new.instance_method #=> Called instance_method within 2148182320 But even though Module.is_a?(Object), you cannot use the macro method in a module: module FooModule macro_method end #=> undefined local variable or method `macro_method' for FooModule:Module (NameError) This is true even if you explicitly include the original Extension into Module with Module.send(:include, Extension). How do you add macro like methods to Ruby modules?

    - by jomblo
    I'm learning CRUD in codeigniter. I have table name "posting" and the coloumns are like this (id, title, post). I successed to create a new post (both insert into database and display in the view). But I have problem when I delete my post in the front-end. Here is my code: Model Class Post_Model extends CI_Model{ function index(){ //Here is my homepage code } function delete_post($id) { $this->db->where('id', $id); $this->db->delete('posting'); } } Controller Class Post extends CI_Controller{ function delete() { $this->load->model('Post_Model'); $this->Post_Model->delete_post("id"); redirect('Post/index/', 'refresh'); } } After click "delete" in the homepage, there was nothing happens. While I'm looking into my database, my records still available. Note: (1) to delete record, I'm following the codeigniter manual / user guide, (2) I found a message error (Undefined variable: id) after hiting the "delete" button in the front-end Any help or suggestion, please

  • Ext.Button handler config option

    - by ppecher
    someClass = Ext.extend(someClassB, { _someFunctionC{ someButton = new Ext.button({ handler: function () { this._onClick('click'); } }), _onClick(someMessage){ Ext.Msg.alert(someMessage); } } } _onClick eats one parameter; in the above code you put in the 'click' event because you want _onClick to be executed after the user clicks on the button. However, how do you specify this specific 'click' registration AND pass in a local variable as the _onClick parameter at the same time? As an aside, why do you even have to specify 'click', when the API states that handler always pertains to a click? Is this additional information not unnecessary?

  • How to write a regular expression for "everything between X and Y" for use with preg_replace

    - by pg
    I want to take a variable called $encoded_str and and remove cd1, CD1 and anything between the first 'l' and the last blank space. So for example "lp6 id4 STRINGcd1" would return "STRING". I'm using PHP 4 for now so I can't use str_ireplace, I have this: $encoded_str=str_replace('CD1','',$encoded_str); $encoded_str=str_replace('cd1','',$encoded_str); $encoded_str=preg_replace('X','',$encoded_str); I've RTFM for preg_replace but am a bit confused. What should I replace the X with and can you suggest a decent introductory primer for writing regular expressions?

  • MySQL Limiting a query to one consistent value

    - by Lucas Matos
    My current query returns a table like: +------------+ value1 | .... value1 | .... value2 | .... value3 | .... +------------+ I want: +------------+ value1 | .... value1 | .... +------------+ I want to only receive all rows with the first value. Normally I would do a WHERE clause if I knew that value, and I cannot use a LIMIT because each value has a different number of rows. Right now My query looks like "SELECT u.*, n.something, w.* FROM ... AS u, ... AS n, ... AS w WHERE u.id = n.id AND w.val = n.val AND u.desc LIKE '%GET REQUEST VARIABLE%';" This works great, except I get way too many rows and using PHP to do this ruins code portability and is superfluous.

  • Why did I get a 400 Bad Request when getting a page with PHP Curl?

    - by user307272
    Hi, I was trying to access a page using curl. I could access it perfectly using the browser and using "static" strings as the URL, like: $url = "http://www.example.com/?q=1234" But when I tried to access the page using a variable in the URL string like: $url = "http://www.example.com/?q=$param" I got a 400 error code. I checked out on the web and found some comments here in this stackoverflow thread: Then, just for curiosity I did the following: $url = "http://www.example.com/?q=" . trim($param); and it worked! And no, $param did NOT contain any spaces. To me, it seems that it can be some encoding error, but I really can't find an explanation for it. Does anyone here in stackoverflow know what it can possibly be? Thanks in advance :)
