correct way to use custom 'content' plugin on all content and components

[TheCellarRoom]

I have a plugin that inserts code snippets on to com_content items but need this to be extended to all other components

I am aware from the joomla docs something such as this:

$dispatcher =& JDispatcher::getInstance();

$item->content = $text;

JPluginHelper::importPlugin('plgContentshortcodes'); 

$dispatcher->trigger('onContentPrepare', array ($item->text, 0));

or this: 

$dispatcher = JDispatcher::getInstance();

$item->text = your_text_area_item;  

$item->params = clone($params);

JPluginHelper::importPlugin('content'); 

$dispatcher->trigger('onPrepareContent', array (& $item, & $item->params, 0))

 should work, but can't seem to make any headway on this 

Does anyone have a working example or guidance please?

Perhaps you can use some of the system plugin events which are called on every page load http://docs.joomla.org/Plugin/Events/System

Should probably add i'm working on version 3.1.1 

[Matt Thomas]

I've had similar situations in the past and have needed to change it from being a content to system plugin.

You can see the content version at https://github.com/betweenbrain/Pseudo-Syntax/blob/ea0994e3f095bf675427c9b4e5e56ef55325359c/pseudosyntax.php and the system version at https://github.com/betweenbrain/Pseudo-Syntax/blob/51da94320c250ae254487849ae8171ae5a662ddf/pseudosyntax.php

That said, based on your code examples, it looks like you are trying to trigger the plugin event in a component, is that correct?

it is yes, although it needs to run in all components.

[Allon Moritz]

If you create a system plugin add the following code in the after render function, otherwise it will break extensions which are using raw(ajax) or other non html requests

if (JFactory::getDocument()->getType() != 'html') {

return;

}

Possibly a little OT, but to avoid headaches I'd suggest that "running in all components" is an impossible task. How could Joomla know which fields of any component is a text field?

Now, if your question is, "how do I run content plugins on a given text", the answer is quite easy:

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

[Matt Thomas]

I think the confusion is that not all components will necessarily trigger the content plugin events.

The suggestion is to change your plugin to be a system type, so that it is always triggered by the CMS regardless of the component.

In my example, I was previously using the onPrepareContent event to alter $article->title, but had to change it to a broader system plugin using onAfterRender so that I could use it outside of com_content and modify the entire page buffer.

In other words, as far as I know, you can't reliably use custom 'content' plugin on all content and components.

yes I think this is the issue, I've moved over to a system plugin. but not working as yet.

essentially the plugin is looking for shortcodes {footer-text}, {contact-details} and replacing with content stored in the custom component, edited in the backend. these 'shortcodes' can appear in any component part of the site as the client sees fit.

thanks to all so far.

Thanks to Matt who was better than me at understanding and explaining the source of confusion.

[joomla ace not]

i have been searching for something like this for a while. The plugin i have created needs to include some external javascript and also insert javascript into the head or body. Does anybody know how that can be achieved? 

Many thanks in advance

[Matt Thomas]

You will need to use http://docs.joomla.org/JDocument/addScript and http://docs.joomla.org/JDocument/addScriptDeclaration to add the script and sript declaration.
