  • Pronunciation of programming structures (particularly in c#)

    - by Andrzej Nosal
    As a non-English speaking person I often have problems pronouncing certain programming structures and abbreviations. I've been watching some video tutorials and listening to podcasts as well, though I couldn't catch them all. My question is what is the common or correct pronunciation of the following code snippets? Generics, like IEnumerable<int> or in a method void Swap<T>(T lhs, T rhs) Collections indexing and indexer access e.g. garage[i], rectangular arrays myArray[2,1] or jagged[1][2][3] Lambda operator =>, e.g. in a where extension method .Where(animal => animal.Color == Color.Brown) or in an anonymous method () => { return false;} Inheritance class Derived : Base (extends?) class SomeClass : IDisposable (implements?) Arithemtic operators += -= *= /= %= ! Are += and -= pronounced the same for events? Collections initializers new int[] { 4, 5, 8, 9, 12, 13, 16, 17 }; Casting MyEnum foo = (MyEnum)(int)yourFloat; (as?) Nullables DateTime? dt = new DateTime?(); I tagged the question with C# as some of them are specific to C# only.

  • Error returning Ajax in IE7

    - by GuiPereira
    Hi everybody! It's my first question here. First of all, sorry for my 'not perfect' english... I'm developing an ASP.NET MVC application with AJAX. I have the following code in the View: <% using(Html.BeginForm(null, "Home", FormMethod.Post, new{id="formcpf"})){ %> <p> <input name="tipo" type="radio" value="GeraCPF" /> CPF <input type="radio" name="tipo" value="GeraCNPJ" /> CNPJ </p> <p> <input type="submit" id="sbmt" value="Gerar" /> <br /><br /> <span id="lblCPF" class="respostaBG"></span> </p> <%} % and the following Javascript to call an Ajax request: $(document).ready(function() { $("form#formcpf").submit(function(event) { $(this).attr("action", $("input[@name='tipo']:checked").val()); event.preventDefault(); hijack(this, update_sessions, "html"); }); }); function hijack(form, callback, format) { $.ajax({ url: form.action, type: form.method, dataType: format, data: $(form).serialize(), success: callback }); } function update_sessions(result) { $("#lblCPF").html(result); } in Firefox and Chrome works fine, but in IE7 sometimes returns the value into the label, sometimes not. I have to keep submiting to get the return. Anyone could help?

  • Phonegap bluetooth plugin not working

    - by user2907333
    First time poster here , so I'm sorry if this question is asked incorrect or if there are any issues. I'm working on a phonegap app for which I need to be able to set up a bluetooth connection between a tablet (android in this case) and a Win CE PC. Currently i'm trying to get the bluetooth part to work on the tablet and i'm using the plug in you can find at https://github.com/tanelih/phonegap-bluetooth-plugin And for the momemt I'm just trying to enable and disable the Bluetooth on the device. In my bluetoothpage.js file i'm using the following method window.bluetooth.prototype.enable(bluetoothTestSucces(),bluetoothTestFail()); The bluetoothTestSucces and bluetoothTestFail functions just show an alert, nothing else. And if i understand the working of phonegap plugins correctly this uses the following code in my bluetooth.js file Bluetooth.prototype.enable = function(onSuccess, onError) { exec(onSuccess, onError, "Bluetooth", "enable", []); } which calls private void enable(JSONArray args, CallbackContext callbackCtx) { try { _bluetooth.enable(); callbackCtx.success(); } catch(Exception e) { this.error(callbackCtx, e.getMessage(), BluetoothError.ERR_UNKNOWN); } } in my BluetoothPlugin.java file. And if the java file returns Succes bluetoothTestSucces() is used and if the java file returns an error bluetoothTestFail() is used. But for some reason it runs both and does not turn on bluetooth on my device. I'm almost certain I've forgotten a link to a file or have linked it wrong somewhere. But I've followed the instructions that were included in the plugin. I've included the Bluetooth permission in my AndoridManifest file which is located in the root directory of my app I've included the plugin in my config.xml file which is located in res/xml I've required the plugin after the deviceready event as follows document.addEventListener("deviceready", onDeviceReady, false); function onDeviceReady() { window.bluetooth = cordova.require("cordova/plugin/bluetooth"); } Could anyone tell me how to fix this or what i've done wrong? thanks Martijn PS: I'm sorry for any language errors, English isn't my native language. edit: forgot to include some code

  • Facelet does not convert formatted currency correctly

    - by c0d3x
    Hi, I have the follwing code inside a facelet page: <h:inputNumber value="bean.property"> <f:convertNumber type="currency" /> </h:inputNumber The converter is because there can be a kind of default value inside the input field, which comes from the bean property. Everything is rendered correctly. The value inside the input field is rendered with an "€" character (e.g. "1.453 €". When I submit the form there comes an error up: "nameOfInputField" konnte nicht als ein Geldbetrag erkannt werden '304,00 â¬' In english it is some like: "nameOfInputField" could not be regognized as an amount of money '304,00 â¬' Please have a look at the "€" character. It seems to be printed as "â¬". While it was rendered correctly before submitting the form, now it looks like "â¬" inside the error message and inside the input field. All pages are encoded in UTF-8. What is the reason for this error? How can fix it? Thanks in advance

  • javascript plugin - singleton pattern?

    - by Adam Kiss
    intro Hello, I'm trying to develop some plugin or/*and* object in javascript, which will control some properties over some object. It will also use jQuery, to ease development. idea This is in pseudocode to give you an idea, since I can't really describe it in english with the right words, it's impossible to go and use google to find out what I want to use (and learn). I will have plugin (maybe object?) with some variables and methods: plugin hideshow(startupconfig){ var c, //collection add: function(what){ c += what; }, do: function(){ c.show().hide().stop(); //example code } } and I will use it this way (or sort-of): var p = new Plugin(); p .add($('p#simple')) .add($('p#simple2')) .do(); note I'm not really looking for jQuery plugin tutorials - it's more like usage of singleton pattern in document in javascript, jQuery is mentione only because it will be used to modify dom and simplify selectors, jQuery plugin maybe just for that one little function add. I'm looking for something, that will sit on top of my document and call functions from itselft based on timer, or user actions, or whatever. problems I don't really know where to start with construction of this object/plugin I'm not really sure how to maintain one variable, which is collection of jQuery objects (something like $('#simple, #simple2');) I would maybe like to extedn jQuery with $.fn.addToPlugin to use chaining of objects, but that should be simple (really just each( p.add($(this)); )) I hope I make any sense, ideas, links or advices appreciated.

    Hello,I just want to create plugin that will when visitor(user,visitor,...) visit some post,remember what post,and to increment counter of that post,I wrote this code,but sometimes,counter is incremented,even post isn't viewed,or post with other Id is added to a table.Can someone help me with this,please.I know that there are plugins for this that I'm trying to do,but still want to write this plugin. function IncrementPostCount($the_content) { global $post; global $wpdb; if(($post->post_status == 'publish') && (int)$post->ID) { if(is_single()) { // just for single post - not for page $postID = (int)$post->ID; $postTitle = urlencode($post->post_title); $postLink = urlencode(get_permalink($post->ID)); $oneRow = $wpdb->get_row("SELECT * FROM wp_postovi WHERE postAjDi='$postID'"); if(empty ($oneRow)) { $postCounter = 1; $data_array = array( 'readnTimes' => $postCounter, 'linkPost'=>$postLink, 'TitlePost'=>$postTitle, 'postAjDi'=>$postID); $wpdb->insert('wp_najcitaniji_postovi', $data_array); } else { $postCounter = intval($oneRow->readnTimes) + 1; $data_array = array('readnTimes' => $postCounter); $where_array = array('postAjDi'=>intval($oneRow->postAjDi)); $wpdb->update('wp_postovi',$data_array,$where_array); } return $the_content; } return $the_content; } } add_filter('the_content','IncrementPostCount'); Sorry on my bad english,tnx in advance.

  • Simple multilingual CMS?

    - by Christoffer
    Hi, I have been searching for a while now for a dead simple CMS with multi-language support. The ideal candidate is very lean and offers the possibility to set up different languages for different domains. It's OK if the language support is provided by a plugin/extension. For example I want example.com to point to English and example.fr should be French. With different URI-mappings for SEO. It can be developed in either of PHP, Ruby or Python and has to be open source. Any tips? Thank you EDIT / MORE DETAILS What I want is a CMS that is as simple to use and grasp for a client as Radiant is, but with tabs on each resource that can translate articles to different languages. Languages have to be able to use multiple domains, one for each language. I want to easily use the same article for more than one language as well as have articles (e.g. blog posts or news stories) that are only connected to one language. The CMS should be very light in core functionality (like Radiant, unlike Drupal/Joomla) but be easily extendable with plugins.

  • Cache of Objects or OutPut in View ? Wich is better ?

    - by Felipe
    Hi everybody, I have an ecommerce working in ASP.Net MVC. i'm using Caching to improve more performace in my pages and it's working fine. I'd link to know what is more performative, for example, I can set OutPutCache in my views and and use this cache for all page OR I could get my List of Products in controller, put it on cache (like the code below) and send it to View to render for the user??? private IEnumerable<Products> GetProductsCache(string key, ProductType type) { if (HttpContext.Cache[key] == null) HttpContext.Cache.Insert(key, ProductRepository.GetProducts(type), null, DateTime.Now.AddMinutes(10), Cache.NoSlidingExpiration); return (IEnumerable<Products>)HttpContext.Cache[key]; } public ActionResult Index() { var home = new HomeViewModel() { Products = GetProductsCache("ProductHomeCache", ProductType.Product) Services = GetProductsCache("ServiceHomeCache", ProductType.Service) }; return View(home); } Both works fine, but I'd like to know what is suggested to improve more performace ? Or is there others way to do it better ? PS: sorry for my english! thanks all... Cheers

  • Removing specific XML tags

    - by iTayb
    I'd like to make an application that removes duplicates from my wpl (Windows PlayList) files. The wpl struct is something like this: <?wpl version="1.0"?> <smil> <head> <meta name="Generator" content="Microsoft Windows Media Player -- 11.0.5721.5145"/> <meta name="AverageRating" content="55"/> <meta name="TotalDuration" content="229844"/> <meta name="ItemCount" content="978"/> <author/> <title>english</title> </head> <body> <seq> <media src="D:\Anime con 2006\Shits\30 Seconds to Mars - 30 Seconds to Mars\30 Seconds to Mars - Capricorn.mp3" tid="{BCC6E6B9-D0F3-449C-91A9-C6EEBD92FFAE}" cid="{D38701EF-1764-4331-A332-50B5CA690104}"/> <media src="E:\emule.incoming\Ke$ha - Coming Unglued.mp3" tid="{E2DB18E5-0449-4FE3-BA09-9DDE18B523B1}"/> <media src="E:\emule.incoming\Lady Gaga - Bad Romance.mp3" tid="{274BD12B-5E79-4165-9314-00DB045D4CD8}"/> <media src="E:\emule.incoming\David Guetta -Sexy Bitch Feat.

How can I remove specific media, in case of duplicates? Thank you very much.

  • What's your preferred pointer declaration style, and why?

    - by Owen
    I know this is about as bad as it gets for "religious" issues, as Jeff calls them. But I want to know why the people who disagree with me on this do so, and hear their justification for their horrific style. I googled for a while and couldn't find a style guide talking about this. So here's how I feel pointers (and references) should be declared: int* pointer = NULL; int& ref = *pointer; int*& pointer_ref = pointer; The asterisk or ampersand goes with the type, because it modifies the type of the variable being declared. EDIT: I hate to keep repeating the word, but when I say it modifies the type I'm speaking semantically. "int* something;" would translate into English as something like "I declare something, which is a pointer to an integer." The "pointer" goes along with the "integer" much more so than it does with the "something." In contrast, the other uses of the ampersand and asterisk, as address-of and dereferencing operators, act on a variable. Here are the other two styles (maybe there are more but I really hope not): int *ugly_but_common; int * uglier_but_fortunately_less_common; Why? Really, why? I can never think of a case where the second is appropriate, and the first only suitable perhaps with something like: int *hag, *beast; But come now... multiple variable declarations on one line is kind of ugly form in itself already.

  • Let multiple highcharts charts appear automatically from mysql data

    - by martini1993
    I have the following problem. I want to make multiple Highcharts webcharts appear automatically based on the data from the database. Let's say we have the following database: ___________________________________________________________________ | | | | | | | | Year | Month | ID | Name User | Wins | Losses | |_______|___________|______|_______________|____________|__________| | 2013 1 21 Tony Stark 3 12 | | 2013 1 52 Bruce Wayne 5 4 | | 2013 1 76 Clark Kent 9 5 | |__________________________________________________________________| (This database is an example, there are a lot more rows in the real database.) And i have the following query: SELECT a.year AS year1, a.month AS month1, a.id AS id, a.name AS nameuser, a.wins AS wins, a.losses AS losses FROM Sales a WHERE a.month = 1 AND a.year = YEAR(NOW()) With this, it is very easy to hardcode a chart with Highcharts. But what I want is that there has to be a webchart per user. So instead of a single webchart with all the users in it, I want multiple charts next to each other based on the data from the database. So instead of this: http://jsfiddle.net/CWSb6/ I want this (But then next to each other): http://jsfiddle.net/DReMD/ It has to be generated automatically with php and mysql. So if there is a new user starting this month, and the new user is saved in the database, the page automatically displays the new user with the related web chart. I find this very hard to accomplish and I need some help to get to the right direction for the solution. Many thanks in advance! (Sorry for my bad english.)

  • Optimization headers for UITableView?

    - by Pask
    I have an optimization problem for the headers of a table with plain style. If I use the standard view for the table (the classic gray with titles set by titleForHeaderInSection:) everything is ok and the scrolling is smooth and immediate. When, instead, use this code to set my personal view: - (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section { return [self headerPerTitolo:[titoliSezioni objectAtIndex:section]]; } - (UIImageView *)headerPerTitolo:(NSString *)titolo { UIImageView *headerView = [[[UIImageView alloc] initWithFrame:CGRectMake(10.0, 0.0, 320.0, 44.0)] autorelease]; headerView.image = [UIImage imageNamed:kNomeImmagineHeader]; headerView.alpha = kAlphaSezioniTablePlain; UILabel * headerLabel = [[[UILabel alloc] initWithFrame:CGRectZero] autorelease]; headerLabel.backgroundColor = [UIColor clearColor]; headerLabel.opaque = NO; headerLabel.textColor = [UIColor whiteColor]; headerLabel.font = [UIFont boldSystemFontOfSize:16]; headerLabel.frame = CGRectMake(10.0,-11.0, 320.0, 44.0); headerLabel.textAlignment = UITextAlignmentLeft; headerLabel.text = titolo; [headerView addSubview:headerLabel]; return headerView; } scrolling is jerky and not immediate (sliding the finger on the screen does not match an immediate shift of the table). I do not know what caused this problem, maybe the fact that every time the method viewForHeaderInSection: is called, the code runs to create a new UIImageView. I tried many ways to solve the problem, such as creating an array of all the necessary view: apart from more time spent loading at startup, there is a continuing problem of low reactivity of the table. 've Attempted by reducing the size of UIImageView positioned from about 66 KB to 4 KB: not only has a deterioration in quality of colors (which distorts a bit 'original graphics), but ... the problem persists! Perhaps you have suggestions about it, or know me obscure techniques that enable me to optimize this aspect of my application ... I apologize for my English, I used Google for translation.

  • Looking for fast, minimal, preferrably free disc cloning software [closed]

    - by Dave
    We have to test our application installation and functionality on many Windows operating system versions and languages (XP, Vista, Win7; English, Spanish, Portuguese, etc; 32-bit & b4-bit.) While we can do much of this in virtual machines, we have noticed that VM's sometimes hide problems, or raise false bugs. So, we need to do "bare metal" OS installation for much of our testing. I have been using Acronis True Image for the past year, and am not impressed. It often gives random errors which require a reboot, and is really slow. For example, when trying to restore an image, it goes through a "Locking partition" cycle about three times (once after you click OK on each step of the wizard), each of which can take 5 minutes to complete. This all happens BEFORE it actually starts the image copy, which is sometimes quick (3-5 minutes), sometimes long (hours). The size of all of our images are roughly the same, so that is not related. So, anyway, I'm looking to switch to something else: I only need very basic functionality--just creating images of entire discs, and then restoring those images onto the exact same hard drive at a later date. That's it. I'm not opposed to paying for a good piece of software, but if there is something free out there that does the job well, that would be a preference. My OS on which the imaging software would run is Windows Vista, but a bootable media (into a Linux flavor) would be fine also, as long as its quick to use and reliable. Recommendations? (Also, moderators, if this should be a CW, I'll be happy to mark it as such; unclear about the rules there.)

  • Magic Methods in Python

    - by dArignac
    Howdy, I'm kind of new to Python and I wonder if there is a way to create something like the magic methods in PHP (http://www.php.net/manual/en/language.oop5.overloading.php#language.oop5.overloading.methods) My aim is to ease the access of child classes in my model. I basically have a parent class that has n child classes. These classes have three values, a language key, a translation key and a translation value. The are describing a kind of generic translation handling. The parent class can have translations for different translation key each in different languages. E.g. the key "title" can be translated into german and english and the key "description" too (and so far and so on) I don't want to get the child classes and filter by the set values (at least I want but not explicitly, the concrete implementation behind the magic method would do this). I want to call parent_class.title['de'] # or also possible maybe parent_class.title('de') for getting the translation of title in german (de). So there has to be a magic method that takes the name of the called method and their params (as in PHP). As far as I dug into Python this is only possible with simple attributes (_getattr_, _setattr_) or with setting/getting directly within the class (_getitem_, _setitem_) which both do not fit my needs. Maybe there is a solution for this? Please help! Thanks in advance!

  • What is the most efficient/elegant way to parse a flat table into a tree?

    - by Tomalak
    Assume you have a flat table that stores an ordered tree hierarchy: Id Name ParentId Order 1 'Node 1' 0 10 2 'Node 1.1' 1 10 3 'Node 2' 0 20 4 'Node 1.1.1' 2 10 5 'Node 2.1' 3 10 6 'Node 1.2' 1 20 What minimalistic approach would you use to output that to HTML (or text, for that matter) as a correctly ordered, correctly intended tree? Assume further you only have basic data structures (arrays and hashmaps), no fancy objects with parent/children references, no ORM, no framework, just your two hands. The table is represented as a result set, which can be accessed randomly. Pseudo code or plain English is okay, this is purely a conceptional question. Bonus question: Is there a fundamentally better way to store a tree structure like this in a RDBMS? EDITS AND ADDITIONS To answer one commenter's (Mark Bessey's) question: A root node is not necessary, because it is never going to be displayed anyway. ParentId = 0 is the convention to express "these are top level". The Order column defines how nodes with the same parent are going to be sorted. The "result set" I spoke of can be pictured as an array of hashmaps (to stay in that terminology). For my example was meant to be already there. Some answers go the extra mile and construct it first, but thats okay. The tree can be arbitrarily deep. Each node can have N children. I did not exactly have a "millions of entries" tree in mind, though. Don't mistake my choice of node naming ('Node 1.1.1') for something to rely on. The nodes could equally well be called 'Frank' or 'Bob', no naming structure is implied, this was merely to make it readable. I have posted my own solution so you guys can pull it to pieces.

  • Making text align equally in both IE and Chrome

    - by bobo
    <style type="text/css"> h2{ font-size:13px; line-height:16px; color:#000000; margin:0; padding:6px 22px; font-family: 'Times New Roman'; } div{ border:1px solid black; } </style> <div> <h2> ????????</h2> </div> Pasting the above codes here: http://htmledit.squarefree.com/ You will see that the text stays a little bit higher in the div in IE than in Chrome, I would like to make them consistent. By adding a &nbsp; after the text within the <h2>in IE, the text will automatically move up, which is consistent with Chrome. But I don't quite like this hack, so I would like to know if anybody knows what problem this is and recommends a better way to fix it if possible. Many thanks to you all. Note: this problem does not appear if the text is english only.

  • Aspect-Oriented Programming in OOP world - breaking rules ?

    - by Maksim Kondratyuk
    Hi 2 all! When I worked on asp.net mvc web site project, I investigated different approaches for validation. Some of them were DataAnotation validation and Validation Block. They use attributes for setting up rules for validation. Like this: [Required] public string Name {get;set;} I was confused how this approach combines with SRP (single responsibilty principle) from OOP world. Also I don't like any business logic in business objects, I prefer "poor business objects" model, but when I decorate my business objects with validation attributes for real requirements, they become ugly (Has a lot of attributes / with localization logic and so on). Idea with attributes realy simple, but in my opinion the validation decoration should be separated from object. I'm not sure is the approach to separate validation rules to xml files or to another objects, maybe it is a solution. Another bad side of AOP - problems with unit testin such code. When I decorated some controller actions with custom attributes for example to import/export TempData between actions or initialize some required services I can't to write proper unit test for testing this actions. Do you think that attributes don't break srp or you just disregard this and think that it's simplest , is not worst way ? P.S. I read some likes articles and discussions and I just want to put things in proper order. P.P.S. sorry for my "fluent" english :=)

  • Problem with document.location.href

    - by novellino
    Hello, I am new to Javascript and Web development and I have a question regarding the document.location.href. I am using a cookie for storing the language the user prefers and then load the english or the swedish version depending on the language. The default language in the beginning is the same as the browser's language, and my index.jsp is the swedish one. The first time everything works fine. The problem is when the cookie exists already. The basic code is: if (language!=null && language!=""){ if (language=="en-US" || language=="en-us") document.location.href = "en/index.jsp"; } else{ //Explorer if (navigator.userLanguage) language = navigator.userLanguage; //other browsers else language = (navigator.language) ? navigator.language : navigator.userLanguage; if (language!=null && language!=""){ setCookie('language', language, 365, '/', 'onCheck'); if (language=="en-US" || language=="en-us") document.location.href = "en/index.jsp"; else if(language=="sv") document.location.href="index.jsp"; } } When the cookie exists we enter the first "if", and there, if the language is swedish it opens the default blabla/index.jsp page. When the language is set to engish it should open the blabla/en/index.jsp but instead it opens the blabla/en/en/index.jsp which of course is wrong. Does anyone know what I am doing wrong?? Thanks

  • How to store an inventory using hashtables?

    - by Harm De Weirdt
    Hello everyone. For an assignment in collego we have to make a script in Perl that allows us to manage an inventory for an e-store. (The example given was Amazon) Users can make orders in a fully text-based environment and the inventory must be updated when an order is completed. Every item in the inventory has 3 to 4 attributes: a product code, a title, a price and for some an amount (MP3's for example do not have this attribute) Since this is my first encounter with Perl, i don't really know how to start. My main problem is how i should "implement" the inventory in the program. One of the functions of the program is searching trough the titles. Another is to make an order, where the user should give a product code. My first idea was a hashtable with the productcode as key. But if i wanted to search in the titles that could be a problem because of this: the hashkey would be something like DVD-123, the information belonging to that key could be "The Green Mask 12" (without the ") where the 12 indicates how many of this DVD are currently in stock. So i'd have to find a way to ignore the 12 in the end. Another solution was to use the title as Hashkey, but that would prove cumbersome too I think. Is there a way to make a hashtable with 2 key's, and when I give only one it returns an array with the other values? (Including the other key and the other information) That way I could use another key depending on what info I need from my inventory. We have to read the default inventory from a txt file looking like this: MP3-72|Lady Gaga - Kiss and Run (Fear of Commitment Monster)|0.99 CD-400|Kings of Leon - Only By The Night|14.50|2 MP3-401|Kings of Leon - Closer|0.85 DVD-144|Live Free or Die Hard|14.99|2 SOFT-864|Windows Vista|49.95 Any help would be appreciated very much :) PS: I am sorry for my bad grammar, English isn't my native language.

  • Validating age field

    - by Marcelo
    Hi people, I'm trying to validate an age field in a form but I'm having some problem. First I tried to make sure that the field will not be send empty. I don't know JavaScript so I searched some scripts and adapted them to this: function isInteger (s) { var i; if (isEmpty(s)) if (isInteger.arguments.length == 1) return 0; else return (isInteger.arguments[1] == true); for (i = 0; i < s.length; i++) { var c = s.charAt(i); if (!isDigit(c)) return false; } return true; } function isEmpty(s) { return ((s == null) || (s.length == 0)) } function validate_required(field,alerttxt) { with (field) { if (value==null||value=="") { alert(alerttxt);return false; } else { return true; } } } function validate_form(thisform) { with (thisform) { if ((validate_required(age,"Age must be filled out!")==false) || isInteger(age,"Age must be and int number")==false)) {email.focus();return false;} } } //html part <form action="doador.php" onsubmit="return validate_form(this)" method="post"> It's working fine for empty fields, but if I type any letters or characters in age field, it'll be sent and saved a 0 in my database. Can anyone help me? Sorry for any mistake in English, and thanks in anvance for your help.

  • wordpress extended_valid_elements for script tag?

    - by John
    Can someone tell me how to tell Wordpress' tinymce editor to NOT strip out script tags? I looked in wp-admin/includes/post.php and added 'extended_valid_elements'=>'script[charset|defer|language|src|type]', to the $initArray. When I do a view source on the CMS post editor, I see taht it does show up like so: <script type="text/javascript"> /* <![CDATA[ */ tinyMCEPreInit = { base : "http://dev.esolar.ca/wp-includes/js/tinymce", suffix : "", query : "ver=327-1235", mceInit : {mode:"specific_textareas", editor_selector:"theEditor", width:"100%", theme:"advanced", skin:"wp_theme", theme_advanced_buttons1:"bold,italic,strikethrough,|,bullist,numlist,blockquote,|,justifyleft,justifycenter,justifyright,|,link,unlink,wp_more,|,spellchecker,fullscreen,wp_adv", theme_advanced_buttons2:"formatselect,underline,justifyfull,forecolor,|,pastetext,pasteword,removeformat,|,charmap,|,outdent,indent,|,undo,redo,wp_help", theme_advanced_buttons3:"", theme_advanced_buttons4:"", language:"en", spellchecker_languages:"+English=en,Danish=da,Dutch=nl,Finnish=fi,French=fr,German=de,Italian=it,Polish=pl,Portuguese=pt,Spanish=es,Swedish=sv", theme_advanced_toolbar_location:"top", theme_advanced_toolbar_align:"left", theme_advanced_statusbar_location:"bottom", theme_advanced_resizing:"1", theme_advanced_resize_horizontal:"", dialog_type:"modal", relative_urls:"", remove_script_host:"", convert_urls:"", apply_source_formatting:"", remove_linebreaks:"1", gecko_spellcheck:"1", entities:"38,amp,60,lt,62,gt", accessibility_focus:"1", tabfocus_elements:"major-publishing-actions", media_strict:"", paste_remove_styles:"1", paste_remove_spans:"1", paste_strip_class_attributes:"all", wpeditimage_disable_captions:"", plugins:"safari,inlinepopups,spellchecker,paste,wordpress,media,fullscreen,wpeditimage,wpgallery,tabfocus"}, load_ext : function(url,lang){var sl=tinymce.ScriptLoader;sl.markDone(url+'/langs/'+lang+'.js');sl.markDone(url+'/langs/'+lang+'_dlg.js');} }; /* ]]> */ </script> But for some reason ,my editor still doesn't save <script> tags. What am I doing wrong?
