A common example of [[Supporting plugins in your component|using plugins]] is to run the '''content plugins''' on some text. This is useful if you want to support plugins that usually work on Content from a custom extension. For the latest release of Joomla! 1.5 {{JVer|1.5}} and newer versions, you can simply use:
−
Using the plugin system in your addon is fairly simple. The most important part is good planning because, to some degree, you're defining an interface for other people to use.
 
  
−
To activate the plugins for your addon, you just have to use the following line of code:
+
<source lang="php">
−
<source>
+
$text = JHTML::_('content.prepare', $text);
−
$result = $mainframe->triggerEvent( 'onSomething', $param );
 
 
</source>
 
</source>
−
This function calls every plugin that has registered itself for the event 'onSomething' and hands over the array $param as parameter.
 
  
−
As a return value you get an array of results from these plugins. All this is of course optional, you could also use the system without parameters and/or a result.

A common example of using plugins is to run the content plugins on some text. This is useful if you want to support plugins that usually work on Content from a custom extension. For the latest release of Joomla! 1.5 Joomla 1.5 and newer versions, you can simply use: 

$text = JHTML::_('content.prepare', $text);

For early versions of Joomla! 1.5, you need to "spell it out": 

$dispatcher =& JDispatcher::getInstance();
$item->text = & your_text_area_item;  
$item->params = clone($params);
JPluginHelper::importPlugin('content'); 
$dispatcher->trigger('onPrepareContent', array (& $item, & $item->params, 0));

You might want to look at core components (for example com_content) for an example.

Also for PHP5.3 compliance please look at the discussion page.
