How to get the full path from the categories to the product?

Question

1C-Bitrix

Let's say there is a certain product located at the following address:

- Категория 1
-- Категория 2
--- Товар

The parameter "#SECTION_CODE_PATH#" appears in the infoblock settings in the "URL of the detailed view page" item. How can I get the full path to an element from the category IDs to generate the corresponding link?

Answer 2

It's a bad idea to use SECTION_CODE_PATH when generating a URL. If you "rebuild" the directory in the future, then all links will change, which will lead to problems with SEO.
Well, on the topic - you can get a link for a specific element like this:

$iterator = \CIBlockElement::GetList(
    [],
    [
        'ID' => $elementId,
    ],
    false,
    false,
    [
        'DETAIL_PAGE_URL',
    ]
);
if ($item = $iterator->GetNext()) {
    echo $item['DETAIL_PAGE_URL'];
}
