Why is the image array not being added to the element?

Question

1C-Bitrix

I made supposedly comments on IB (it’s convenient for me), I made a form for adding a comment with the following handler:

<?
require($_SERVER["DOCUMENT_ROOT"]."/bitrix/header.php");
if(!defined("B_PROLOG_INCLUDED") || B_PROLOG_INCLUDED!==true) die('Скрипт должен быть запущен в битриксе');
?>
<?
if($APPLICATION->CaptchaCheckCode($_POST["captcha_word"], $_POST["captcha_code"]) || ($USER->IsAuthorized()))
{


    CModule::IncludeModule('iblock');

    $el = new CIBlockElement;

    $fields = array(
        "DATE_CREATE" => date("d.m.Y H:i:s"),
        "DATE_ACTIVE_FROM" => date("d.m.Y H:i:s"),
        "IBLOCK_ID" => (int) $_POST['iblockID'],
        "NAME" => strip_tags($_POST['authorName']),
        "ACTIVE" => "Y",
        "PREVIEW_TEXT" => strip_tags($_REQUEST['comment']),
        "PREVIEW_PICTURE" => NULL,
        "PROPERTY_VALUES" => [
            "LINKED_USER" => NULL,
            "LINKED_ELEMENT" => $_POST['linkedElement'],
        ]
    );
    
    if ($USER->IsAuthorized()){
        $fields['PREVIEW_PICTURE'] = CFile::GetFileArray($USER->GetParam('PERSONAL_PHOTO'));
        $fields['PROPERTY_VALUES']['LINKED_USER'] = $USER->GetID();
    }

    if ($ID = $el->Add($fields)) {
        echo "Сохранено";
        dump($fields['PREVIEW_PICTURE']);
        $rs = CIBlockElement::GetList(array(), array("ID" => $ID), false, false, array("ID", "PREVIEW_PICTURE")); 
        if($ar = $rs->GetNext()) 
            dump($ar);
        //header('Location: '.$_SERVER['HTTP_REFERER']);
    } else {
        echo '<p>Ошибка при добавлении:<br>'.$el->LAST_ERROR.'</p>';
    }
    
}else{
    die('<p>Капча введена неправильно!</p>');
}
?>

I can't get the add method to add the PREVIEW_PICTURE array to the element. Everything is fine in the first dump, but there is no array in the second one:


How to fix this?

Answer 1

The path to the image must start with $_SERVER['DOCUMENT_ROOT']

Answer 2

in the same place it seems not the array is stored, but the id of the picture

Answer 3

Why do you want to copy the user's avatar in each review? This is at least not rational. The user ID is already stored in the recall, when displaying the picture, just get his avatar.
