Okay, I think I managed it this way:
add_action( 'gform_pre_submission_1', 'gf_override_field_with_choice_label' );
function gf_override_field_with_choice_label( $form ) {
$post_id = get_query_var('course');
$startdate = rgpost( 'input_38' );
$first_row_value = get_post_meta($post_id, 'course_info_0_startdate', true);
$second_row_value = get_post_meta($post_id, 'course_info_1_startdate', true);
if ($startdate == $first_row_value) {
$_POST['input_40'] = get_post_meta($post_id, 'course_info_0_location', true);
} else if ($startdate == $second_row_value {
$_POST['input_40'] = get_post_meta($post_id, 'course_info_1_location', true);
} else {
$_POST['input_42'] = 'no value';
}
}
Don’t know whether there would be an easier/cleaner way? Or is this the right way?
