frm_force_calculation_on_validate

Heads up! This article contains PHP code and is intended for developers. We offer this code as a courtesy, but don't provide support for code customizations or 3rd party development.

Apply this filter to enforce calculation during server-side validation. It is disabled by default.

Note: This is an experimental feature and doesn't fully support all calculation types yet. See below for some of the limitations.
  • Calculations that use repeated values, or calculation fields in a repeater.
  • .toFixed()
  • [age] / [date_calc] shortcodes
  • Ternary expressions that involve ? and : characters.
  • Any shortcode options like show="value" / show="label".

Usage

add_filter('frm_force_calculation_on_validate', 'force_calculation_on_validate', 10, 2);

}, 10, 2 );

Force only specific field IDs

add_filter( 'frm_force_calculation_on_validate', function( $force, $field ) {
	$ids_to_force = array( 3852 );
	$force = in_array( (int) $field->id, $ids_to_force, true );
	return $force;
}, 10, 2 );
