Description

The “gform_field_filters” filter in Gravity Forms enables the filter settings to be overridden for the form fields, entry properties, and entry meta.

Usage

add_filter( 'gform_field_filters', 'your_function_name', 10, 2 ); 

Examples

1. Add a custom payment status

add_filter( 'gform_field_filters', 'update_filters', 10, 2 );
function update_filters( $field_filters, $form ){
  foreach ( $field_filters as &$filter ){
  	if ( $filter['key'] == 'payment_status' ){
  		//add custom payment status
  		$values = $filter['values'];
  		$status_exists = false;
  		foreach( $values as &$value ){
  			if ( $value['text'] == 'Test Status' ){
  				$status_exists = true;
  			}
  		}
  		if ( ! $status_exists ){
  			//add status
  			array_push( $values, array( 'text' => 'Test Status', 'value' => 'Test Status' ) );
  			$filter['values'] = $values;
  		}
  	}
  }
  return $field_filters;
}

2. Add an operator to a specific field

add_filter( 'gform_field_filters', function ( $field_filters, $form ) {
   foreach ( $field_filters as $filter ) {
      if ( rgar( $filter, 'key' ) == '2' ) {
         $filter['operators'][] = 'isnot';
         break;
      }
