I’m working on a custom plugin for wordpress to show a maintenance mode screen to users. Ive followed a guide but I have some truble while I’m debugging the code. xdebug will show me these errors:
Warning: require_once(): http:// wrapper is disabled in the server configuration by allow_url_include=0
Warning: require_once(http://localhost/wordpress/wp-content/plugins/maintenance-mode/assets/maintenance.php): failed to open stream: no suitable wrapper could be found
Fatal error: require_once(): Failed opening required ‘http://localhost/wordpress/wp-content/plugins/maintenance-mode/assets/maintenance.php‘ (include_path=’.:/usr/local/php5/lib/php’)
I’m using the plugins_url
to load the path where the maintenance.php file is saved, and before th error I was using plugins_dir_path
but with the same result.
Is there a fix for this?
class Maintenance { public function init() { add_action( 'wp_loaded', array($this, 'maintenance_mode') ); //add_action( 'admin_init', array($this, 'maintenance_settings') ); } public function maintenance_mode() { global $pagenow; if( $pagenow !== 'wp-login.php' && !current_user_can('manage_options') && !is_admin() ){ header( $_SERVER['SERVER_PROTOCOL'] . '503 Service Temporarily Unavailable', true, 503 ); header( 'Content-Type: text/html; charset=utf-8' ); require_once plugins_url('assets/maintenance.php' ,__FILE__); } die(); } }

Answer
Try use plugin_dir_path( __FILE__ )
:
class Maintenance { public function init() { add_action( 'wp_loaded', array($this, 'maintenance_mode') ); //add_action( 'admin_init', array($this, 'maintenance_settings') ); } public function maintenance_mode() { global $pagenow; if( $pagenow !== 'wp-login.php' && !current_user_can('manage_options') && !is_admin() ){ header( $_SERVER['SERVER_PROTOCOL'] . '503 Service Temporarily Unavailable', true, 503 ); header( 'Content-Type: text/html; charset=utf-8' ); require_once plugin_dir_path( __FILE__ ) . 'assets/maintenance.php'; } die(); } }
