To run the hook, copy the example below.

$display_before = apply_filters( 'ninja_forms_display_before_field_key_{$settings}key', $display_before ); 
                         
if ( !empty( $display_before ) ) { 
                         
   // everything has led up to this point... 
                         
} 
  

The following example is for adding a hook callback.

// define the ninja_forms_display_before_field_key_<settings>key callback 
function filter_ninja_forms_display_before_field_key_settingskey( $display_before ) { 
    // make filter magic happen here... 
    return $display_before; 
}; 
         
// add the filter 
add_filter( "ninja_forms_display_before_field_key_{$settings}key", 'filter_ninja_forms_display_before_field_key_settingskey', 10, 1 ); 

To remove a hook callback, use the example below.

// remove the filter 
remove_filter( "ninja_forms_display_before_field_key_{$settings}key", 'filter_ninja_forms_display_before_field_key_settingskey', 10, 1 );
