in the development of the WordPress site to the customer, usually give the customer an administrator account, so the customer is fully capable of modifying the site's theme, Plug-ins, users and some key settings.

But sometimes the user will accidentally do some misoperation, such as the use of the necessary plug-ins, in this case, we can put some plug-ins in the list of Plug-ins hidden, and in fact the plug-in is still in the normal operation.

The following code hides the WP Crontrol and User switching two plug-ins in the plugin list, and can still see the plugin when the plugin is deactivated, only the plugin will be hidden from the list when the plugin is enabled.

/**
  *wordpress Hide some plugins in the plugin
  list
*http://www.endskin.com/hide-plugins/
/function Bing_hide_plugins ($ Plugins) {
 
  //hide WP Crontrol plugin
  $plugin = ' wp-crontrol/wp-crontrol.php ';
  if (is_plugin_active ($plugin)) unset ($plugins [$plugin]);
 
  Hide User Switching plugin
  $plugin = ' user-switching/user-switching.php ';
  if (is_plugin_active ($plugin)) unset ($plugins [$plugin]);
 
  return $plugins;
}
Add_filter (' All_plugins ', ' bing_hide_plugins ');
