Description

apply_filters( 'pre_user_display_name', (string) $display_name );

0. $display_name (string)

The user's display name.

Usage

To run the hook, copy the example below.

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

The following example is for adding a hook callback.

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

To remove a hook callback, use the example below.

// remove the filter 
remove_filter( 'pre_user_display_name', 'filter_pre_user_display_name', 10, 1 );
