This plugin allows SocialMagick to integrate with Joomla contact categories. You must have this plugin enabled for SocialMagick to generate OpenGraph images for contact category pages.
This integration plugin only applies to contact categories. It does not apply to categories used by other components such as Articles, Banners, or News Feeds.
The plugin is responsible for rendering the OpenGraph tab when you are editing a contact category.
When your frontend page is displaying a contact category (e.g. a category list of contacts), this plugin makes the following information available to SocialMagick:
The category title can be used as the OpenGraph image template text when you enable Use Content Title.
The category's Image can be used as the Extra Image in the OpenGraph image template.
A Joomla custom Field can be used as the Extra Image in the OpenGraph image template.
The category's Meta Description is used as the OpenGraph description.
The Access for this plugin MUST always be set to Public. See the Advanced tab for options limiting access to the OpenGraph tab to specific user groups.
The Advanced tab allows you to specify who for and where the OpenGraph tab will be visible when editing a contact category.
All users who belong to the Super User group are NOT limited by the options in this tab. Super User accounts can always see the OpenGraph tab. The reason is that Super Users in Joomla have, by definition, all privileges explicitly Allowed to them, i.e. the should and can do anything and everything on the site.
If this is empty, any user who can edit a contact category will see the OpenGraph tab. Otherwise, only users belonging to one or more of the groups specified here –or one of their child groups– will be see that tab. Super Users are not limited by this setting.
