Whether to trigger deprecated hook errors. Requires WP_DEBUG to be defined true.

Usage

To run the hook, copy the example below.

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

The following example is for adding a hook callback.

// define the deprecated_hook_trigger_error callback 
function filter_deprecated_hook_trigger_error( $true ) { 
    // make filter magic happen here... 
    return $true; 
}; 
         
// add the filter 
add_filter( 'deprecated_hook_trigger_error', 'filter_deprecated_hook_trigger_error', 10, 1 ); 

To remove a hook callback, use the example below.

// remove the filter 
remove_filter( 'deprecated_hook_trigger_error', 'filter_deprecated_hook_trigger_error', 10, 1 );
