How to pass a checked Checkbox when creating an infoblock element from the frontend side?

Question

Good afternoon.

There is a form with a checkbox input, which, when submitted, creates an element in the infoblock.
Parameters are passed

$arFields = array(
 "PROPERTY_VALUES" 	=> array (
      "FORM_REQUEST"     => $_POST['FORM_REQUEST'] !== false ? "Y" : ""
  )
);
$oElement = new CIBlockElement();
$idElement = $oElement->Add($arFields, false, false, true);

The element is created, but the checkbox in the FORM_REQUEST property of the element is not checked,
what's wrong?

Answer 1

It turns out that you need to pass the value ID, like this:

"FORM_REQUEST"		=> isset($_POST['FORM_REQUEST']) ? array(4) : ''
