Question

1C-Bitrix

Hello!
Here is the task, I tried the options for inserting product properties in the display on the sheet of my elements that I knew -

$arElement["PROPERTIES"] ["Свойство"] ["VALUE"],  а так же $arItem~, $arResult~

,
but nothing works.
Tell me how to add, for example, a preview image (product cover) to the list item, it is not in the properties, but in the fields .. and additionally the code for adding the display of properties!
Thank you!

Answer 1

Print the data of the resulting array $arResult
<?print_r($arResult);?>
[PREVIEW_PICTURE] => 2138 this is the ID of the registered file, you can get the picture itself from it
[ELEMENTS][ID] - by ID you can get the values ​​of the element properties, including and custom fields using the CIBlockElement-GetList and CIBlockElement-GetProperty APIs
