grant_super_admin() │ WP 3.0.0

Grants Super Admin privileges.

Uses: update_site_option()

Hooks from the function

grant_super_admin

granted_super_admin

Return

true|false. True on success, false on failure. This can fail when the user is already a super admin or when the $super_admins global is defined.

Usage

grant_super_admin( $user_id );

$user_id(int) (required): ID of the user to be granted Super Admin privileges.

Examples

#1 Give super admin rights (caps) to the user with ID 5

It is recommended to call the function only once, not every time the page is generated. Because it changes the value of the option.

grant_super_admin( 5 );

#2 Set super-admin rights (caps) and remove them when activating/deactivating the plugin

register_activation_hook( __FILE__, 'myplugin_activate' );
register_deactivation_hook( __FILE__, 'myplugin_deactivate' );

function myplugin_activate() {

	// give caps
	grant_super_admin( 5 );
}

function myplugin_deactivate(){

	// take away the caps
	revoke_super_admin( 5 );
}

Notes

Global. Array. $super_admins
