editors-xtd and content display

[Allan Jardine]

Hi all,

I'm new to developing plug-ins for Joomla, so my apologies if I get any of the terminology wrong. Also, this is cross posted from the Joomla forum - I should have posted here in the first place - sorry.

I've successfully created an `editors-xtd` plug-in to add a button below the editing panel (by basing it on the core's own plug-ins). I don't get how I can control the layout of the iframe stuff yet, but I haven't looked into it properly.

The main issue I'm having trouble with is that I need to modify the content of an article before it is displayed. I can't just insert HTML into the editor as I need temporary tokens when the page is loaded. So my plan was to have the editors-xtd plug-in insert a token such as `[embed 1234]` and then transform that on output with `onContentPrepare`. This is where the wheels come off.

How can I have my editors-xtd plug-in also operate on the content output? Brian in the forum noted I can't use `onContentPrepare` in an editors-xtd plug-in. In which case how can I add an option to the editor and also modify the output when displayed to the end user?

Thanks,
Allan

I think the answer is that you actually create two plugins - an editors-xtd one to make an editor button which inserts the shortcode for the what you will want to insert (the convention is to use {} curly braces around the shortcode) and then a content plugin to convert the shortcode into the content you wish to insert onContentPrepare

Or at least as I remember that's what I did for my footnote plugin - https://crosborne.uk/jplugins/footnote-tag which might give you some clues

Hi Roger,

Many thanks for your reply and the link to your plug-in. That is really useful, particularly the install package script - thank you!

One thing I'm not clear on is how to share configuration settings between the two plug-ins. Do you (or anyone else who can chime in) know how that can be done?

Thanks,

Allan

In case anyone else finds this post and isn't sure how to do it, I found that you can call:

$plugin = JPluginHelper::getPlugin('content', 'pluginname');

Then:

$pluginParams = new JRegistry($plugin->params);

$apiKey = $pluginParams->get('paramName');

I'm sure it will be documented somewhere - but I couldn't see it. Found it by digging through other plug-ins such as Roger's :-).

Thanks,

Allan
