What is this?
Why would I need it?
For example, if you wish to embed a Google Map onto your site, simply copying and pasting the embeddable code into an article (or custom HTML module) will not work unless the default WYSIWYG editor is switched off beforehand. You are unlikely to want this switched off for long so you would then have to switch the editor back on after you have entered your code. This is an over-complicated process and if you (or a client) were to edit the page without switching off the editor first, your code (and your Google Map) would be broken.
HD-AnyCode offers a far simpler solution: Any code entered into this module will be rendered as is.
What to do after installing?
Install the zip file via the administration install manager as per any other module. Once it has installed go to the plugin manager and select HD-AnyCode. Enable the module, set the module position, allocate to a menu page, enter your code and click on apply.
How do I insert code within an article?
If you want the module to be included within an article rather than in a pre-defined module position you should use the loadposition command. Add this code to the relevant position in your article...
Substituting x with a module position name of your choice.
Then when you allocate your module position, rather than choosing left, right, user1 etc, enter x into the drop down selection box.
