How to update multiple file type field when?

Question

1C-Bitrix

I update the elements with the code using CIBlockElement::Update
The multiple property of the file type adds more photos, but it is necessary that the previous ones be deleted and new ones added. What needs to be done for this? (no need to delete the file)

Answer 1

Something like this:

$rsProp = CIBlockElement::GetProperty($IBLOCK_ID, $ELEMENT_ID, array('sort' => 'asc'), array('CODE' => 'FILES'));
while($arProp = $rsProp->Fetch())
  $PROPERTY_VALUE[$arProp['PROPERTY_VALUE_ID']] = array('VALUE' => array('del'=>'Y'));

$PROPERTY_VALUE[] = CFile::MakeFileArray($_SERVER["DOCUMENT_ROOT"]."/new_image.jpg");

CIBlockElement::SetPropertyValues($ELEMENT_ID, $IBLOCK_ID, $PROPERTY_VALUE, 'FILES');

for Update it is similar, you need to pass array('VALUE' => array('del'=>'Y'))
