Usage

To run the hook, copy the example below.

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

The following example is for adding a hook callback.

// define the default_checkout_<input> callback 
function filter_default_checkout_input( $value, $input ) { 
    // make filter magic happen here... 
    return $value; 
}; 
         
// add the filter 
add_filter( "default_checkout_{$input}", 'filter_default_checkout_input', 10, 2 ); 

To remove a hook callback, use the example below.

// remove the filter 
remove_filter( "default_checkout_{$input}", 'filter_default_checkout_input', 10, 2 );
