pattihis / safe_get_query_var.php
Created March 1, 2025 18:08
A replacement function for WordPress's get_query_var() that addresses the issue of query variables not being set on some servers, by parsing the globals directly.
<?php
/**
* Get the query variable even if the server rewrite rules do not support it.
* This is a workaround for the issue where the query vars are not set in the globals.
*
* @global WP_Query $wp_query WordPress Query object.
*
* @param string $query_var The variable key to retrieve.
* @param mixed $default_value Optional. Value to return if the query variable is not set.
* Default empty string.
