Display all hooks on a page

Temporary and dev or staging site use only. Displays all hooks on the front end so developers can see which hooks are ran visually within the site’s layouts. In this example we only apply this to the /checkout/order-received/ page.

add_action( 'template_redirect', function() {

	// Isolate To One Page
	global $wp;
	if( empty( $wp->query_vars['order-received'] ) ) {

	// Hook All
	add_action( 'all', function( $tag ) {

		// Avoid The Admin Area
		if( is_admin() ) {

		// Only Woo Core Hooks
		if( substr( $tag, 0, 12 ) == 'woocommerce_' ) {

			// Print The Hook
			echo $tag . ' ';

	} );

} );
