Description

apply_filters( 'pre_handle_404', (bool) $false, (WP_Query) $wp_query ); 

Returning a non-false value from the filter will short-circuit the handling and return early.

Parameters (2)

0. $false (bool) => false

Whether to short-circuit default header status handling. Default false.

1. $wp_query (WP_Query)

WordPress Query object.

Usage

To run the hook, copy the example below.

$false = apply_filters( 'pre_handle_404', $false, $wp_query ); 
                         
if ( !empty( $false ) ) { 
                         
   // everything has led up to this point... 
                         
} 
  

The following example is for adding a hook callback.

// define the pre_handle_404 callback 
function filter_pre_handle_404( $false, $wp_query ) { 
    // make filter magic happen here... 
    return $false; 
}; 
         
// add the filter 
add_filter( 'pre_handle_404', 'filter_pre_handle_404', 10, 2 ); 

To remove a hook callback, use the example below.

// remove the filter 
remove_filter( 'pre_handle_404', 'filter_pre_handle_404', 10, 2 );
