[SOLVED] Using Joomla! Events in CB Auto Actions

I had the fortune today of needing one of the provided Joomla! events to create an Auto Action. Perhaps the GOOD fortune of not really needing any of the parameters passed into a plugin triggered off that event. But it raised the question: What if I needed to access the parameters? Can I?

The event I used is joomla_onContentAfterDisplay, which has the following interface:

• context - The context of the content being passed to the plugin - this is the component name and view - or name of module (e.g. com_content.article). Use this to check whether you are in the desired context for the plugin.
• & article - The article that is being rendered by the view.
• & params - A JRegistry object of merged article and menu item params.
• limitstart - An integer that determines the "page" of the content that is to be generated.

Is this documented somewhere? I searched for joomla_on and found nothing relevant.

If I were writing a plugin for this Joomla! event, I could get to the article title, for example, with $article->title. How would I get to that in my Auto-Action? Would I need to use a Code action and could I just use that type of reference? How about if I needed a non-Code action? Can it be used in a substitution-style syntax, perhaps something like [article->title]?

Thanks,

Yes, you access them the same way you would with CB triggers using var1, var2, etc..

Joomla events are documented in Joomla documentation.

How would I get to that in my Auto-Action?

Since $article is the second variable of the event you'd access it with [var2], but since it's an object you'd need to access its properties. For title specifically you'd use [var2_title].

Would I need to use a Code action and could I just use that type of reference?

You can access them from a Code action using the $variables variable. So for example $variables->title for article title. You're not required to use a code action as they can be substituted fine (see above quote). If you need to modify the variables by reference you can do so from a Code action our the Output after setting the appropriate variable as a reference variable under the parameters tab.

Thanks, Kyle. You da man!
