WordPress prints the current version and update information, using core_update_footer(…) at priority 10.

Parameters (1)

The content that will be printed.

Usage

To run the hook, copy the example below.

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

The following example is for adding a hook callback.

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

To remove a hook callback, use the example below.

// remove the filter 
remove_filter( 'update_footer', 'filter_update_footer', 10, 1 );
