This answer lets you redirect back to the originating post instead of dieing with the flood message. It’s a PHP class, not just a simple function. You can copy-paste this into your functions.php as-is, or set it up in whichever way you like to manage your custom code.
- assumes PHP 5.3+
- it also contains code for duplicate comments which your original question mentioned, but then you edited it out. You can remove this bit by deleting the line that contains
add_action( 'comment_duplicate_trigger,…
class Handle_Comment_Flood {
private $comment_post_id;
public function __construct() {
add_filter( 'preprocess_comment', [ $this, 'capture_post_id' ], 10, 1 );
add_action( 'comment_flood_trigger', [ $this, 'handle_redirect' ], 0, 0 );
add_action( 'comment_duplicate_trigger', [ $this, 'handle_redirect' ], 0, 0 );
}
public function capture_post_id( $comment ) {
$this->comment_post_id = isset( $comment[ 'comment_post_ID' ] ) ? $comment[ 'comment_post_ID' ] : 0;
return $comment;
}
public function handle_redirect() {
if ( !empty( $this->comment_post_id ) ) {
wp_safe_redirect( get_permalink( get_post( $this->comment_post_id ) ) );
die();
}
}
}
new Handle_Comment_Flood();
