Plugin Dependencies


Parses a ‘Requires Plugins’ header and adds a Dependencies tab in the plugin install page. If a requiring plugin does not have all its dependencies installed and active, it will not activate.

My solution to #22316. Feature plugin version of PR #1724

  • Parses the Requires Plugins header that defines plugin dependencies using a comma separated list of slugs. To test, you will need to add the header and content to a plugin.
  • Adds a new view/tab to plugins install page ( Plugins > Add New ) titled Dependencies that contains plugin cards for all plugin dependencies.
  • This view also lists which plugins require which plugin dependencies in the plugin card. 😅
  • In the plugins page, a dependent plugin is unable to be deleted or deactivated if the requiring plugin is active.
  • Plugin dependencies can be deactivated or deleted if the requiring plugin is not active.
  • Messaging in the plugin row description is inserted; as is data noting which plugins require the dependency.
  • Displays a single admin notice with link to Plugins > Add New > Dependencies if not all plugin dependencies have been installed.
  • Ensures that plugins with unmet dependencies cannot be activated.
  • If the dependency API data is not available a generic plugin card will be displayed in the Dependencies tab.

There are several single file plugins that may be used for testing in test-plugins/.

  • Plugin is a Dependency and Plugin needing Dependencies
  • Plugin with Dependencies
  • Plugin Dependencies tab


June 14, 2022
There is a good plugin, but the plugin page is very crowded and getting to the bottom of the page happens later, which is not good for everyone. An option must be added so that the user or developer can easily enable or disable the display of this plugin information from the page settings at the top of the plugins page.
