Adding your Extension

The “mainwp_getextensions” filter is used to add your extension to MainWP.


Where ‘plugin_get_extension’ is the function MainWP should call when the $extensions array is being retrieved. Note that the filter function must return an array of extensions after it is finished processing, or no extensions will be displayed, and other plugins also filtering the $extensions array may generate errors.

plugin_get_extension should be unique function name. It cannot match any other function name already declared.

Both examples use the following two actions to add the settings page header and footer: mainwp-pageheader-extensions and mainwp-pagefooter-extensions
