Revision UI fields. Each item is an array of id, name and diff.

The revision post to compare from.

2. $compare_to (WP_Post)

Usage

To run the hook, copy the example below.

$return = apply_filters( 'wp_get_revision_ui_diff', $return, $compare_from, $compare_to ); 
                         
if ( !empty( $return ) ) { 
                         
   // everything has led up to this point... 
                         
} 
  

The following example is for adding a hook callback.

// define the wp_get_revision_ui_diff callback 
function filter_wp_get_revision_ui_diff( $return, $compare_from, $compare_to ) { 
    // make filter magic happen here... 
    return $return; 
}; 
         
// add the filter 
add_filter( 'wp_get_revision_ui_diff', 'filter_wp_get_revision_ui_diff', 10, 3 ); 

To remove a hook callback, use the example below.

// remove the filter 
remove_filter( 'wp_get_revision_ui_diff', 'filter_wp_get_revision_ui_diff', 10, 3 );
