So, let’s dive into the world of WordPress hooks! Today, we’re focusing on the parse_query action. This hook is pretty handy as it fires after the main query vars have been parsed. To make use of the parse_query action, you need to register it using add_action. You can place this code in the functions.php file of your active theme or, even better, in a custom WordPress Plugin. Why? Because creating a custom plugin ensures that nothing breaks when you update your WordPress Theme in the future.
WePlugins always recommends creating a custom WordPress Plugin while using hooks for this reason. If you ever need to remove a registered hook, you can use remove_action to remove the parse_query action.
Let’s look at a basic example where we set a custom query variable.
function weplugins_set_custom_isvars( $query ) {
$query->is_foo = true;
}
add_action( 'parse_query', 'weplugins_set_custom_isvars' );
Below is another example of how you can use this hook to execute custom code during the parse_query event in WordPress.
function weplugins_execute_on_parse_query_event($query){
// Write custom code here to execute during the parse_query event.
}
add_action( "parse_query", "weplugins_execute_on_parse_query_event" , 10, 1);
If you decide to remove a hook callback, here’s how you can do it. Remember to provide the same callback function name, priority, and number of arguments when removing the hook callback.
remove_action( "parse_query", "weplugins_execute_on_parse_query_event", 10, 1 );
