Use the frm_option_is_valid filter to change choice-field option validation. Formidable validates submitted choice values against the options configured for the field.

Requirements

• Formidable Forms 6.21 or later.
• Formidable API Add-On installed and activated when you use a REST API example.

Usage

add_filter( 'frm_option_is_valid', '__return_true' );

Parameters

• $is_valid (bool): Whether the submitted value matches a configured field option.
• $value (array|string): The submitted field value.
• $field (object): The field being validated.

Examples

Disable option validation

This example disables option validation for every field and every submission path.

add_filter( 'frm_option_is_valid', '__return_true' );

Add an exception for direct REST API entry requests

This example adds an option-validation exception for direct Formidable REST API v2 and v3 entry routes.

add_filter( 'frm_option_is_valid', function( $is_valid ) {
    if ( $is_valid ) {
        return true;
    }

    $request_uri = FrmAppHelper::get_server_value( 'REQUEST_URI' );
    $entry_routes = array(
        '/wp-json/frm/v2/entries',
        '/wp-json/frm/v3/entries',
    );

    foreach ( $entry_routes as $entry_route ) {
        if ( 0 === strpos( $request_uri, $entry_route ) ) {
            return true;
        }
    }

    return $is_valid;
} );

Add exemptions only for specific field IDs

This example allows unconfigured option values only for the listed field IDs. Replace 1, 2, and 3 with the required field IDs.

add_filter( 'frm_option_is_valid', function( $is_valid, $value, $field ) {
    if ( ! $is_valid ) {
        $field_id_exceptions = array( 1, 2, 3 );

        if ( in_array( (int) $field->id, $field_id_exceptions, true ) ) {
            $is_valid = true;
        }
    }

    return $is_valid;
}, 10, 3 );

Limitations

• Disabling option validation can store values that do not appear in the field's configured choices.
• A request-URL check applies only to the routes included in the condition.
• The field-ID example applies wherever Formidable validates the listed fields, including normal submissions and supported API entry operations.
