Joomla 3.x embedding visual code

Question

Does someone know a way to embed source code (C++, C#, HTML, etc.) to a Joomla article? Almost the same way like in this page, where I can add a code sample. Only showing the code, it must not be executed

kind regards

Max

You can't add c++ and c# but for HTML and PHP there are many extension available like JUMI or DirectPHP on joomla extension directory.

By default, text editors in Joomla administrator interface work in visual (WYSIWYG) mode. WYSIWYG editors allow editing the HTML markup when you just need to publish some text and throw bolds and headers here and there, but when you try to publish a Javascript code through it, it will do its best to reformat it in the way that it shows up as a readable text, not as an actual working code. Moreover, there are security settings in Joomla that can prohibit using of Javascript codes within an HTML, in such cases the text editor just strips all <script> blocks. Thus, when adding some custom Javascript in your article or custom HTML module, you might find out that it doesn't work in the front end or even disappears from HTML sources. Please follow these instructions in order to solve such problems.

1. Set up general text filtering options for being able to use Javascript safely inside HTML source editor.

   → Open Content → Article Manager in your Joomla administrator panel and click on the Options button in top right corner
   → In the new popup window with Article Manager Options, open the Text Filters tab and select No Filtering under your user group (it is usually 'Super Users')
   → Click Save

2. Configure your text editor so that it allows you to have <script> elements in your code.

   The text editor that you use in Joomla may set its own security settings, which can affect code formatting. By default, the TinyMCE is used in Joomla administrator interface. Here is how to configure it properly:

   → In your administrator panel, go to Extensions → Plug-in Manager, find the Editors - TinyMCE line and click it
   → In TinyMCE options on right, find Prohibited elements section and remove a mention of 'script' from it
   → Click Save

3. Use the 'HTML' mode when pasting the javascript codes into HTML.

No matter what editor you're using, when trying to insert a javascript code you need to switch the editor into the HTML mode first - look for HTML button or tab somewhere around the editor area. With that mode the codes that you enter into editor are to be treated as exactly the codes and should work. Joomla administrator interface sometimes also features a button reading 'Toggle editor' below the actual editor - you can switch from WYSIWYG into the code editor by hitting that button.

By using the above-mentioned recommendations, you'll be able to make JavaScript codes work inside your HTML sources in Joomla. Comdev is a Joomla development services provider, which provides varieties of Joomla extensions.
