Usage

To run the hook, copy the example below.

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

The following example is for adding a hook callback.

// define the ninja_forms_export_sub_pre_value callback 
function filter_ninja_forms_export_sub_pre_value( $user_value, $field_id ) { 
    // make filter magic happen here... 
    return $user_value; 
}; 
         
// add the filter 
add_filter( 'ninja_forms_export_sub_pre_value', 'filter_ninja_forms_export_sub_pre_value', 10, 2 ); 

To remove a hook callback, use the example below.

// remove the filter 
remove_filter( 'ninja_forms_export_sub_pre_value', 'filter_ninja_forms_export_sub_pre_value', 10, 2 );
