In the catalog section, you need to display a link to download the pdf file.


This method does not work:

$rsResult = CIBlockSection::GetList(array("SORT" => "ASC"), array("IBLOCK_ID" => $arItems["IBLOCK_ID"], "ID" => $arItems["ID"]), false, $arSelect = array("UF_*"));
if($arSection = $rsResult->GetNext()) { 
$pdf_Link = $arSection["UF_PDF"];
}

<a href="<?=CFile::GetPath($pdf_Link);?>">pdf</a>

How to display a custom field of the File type in Bitrix?

For the administrative panel, when uploading a file, it will be shown automatically.
Also, if you use the bitrix:news* components, then you can specify the property to receive, and in some cases it will even display itself (in specially designated places).
There are other ways to display a file: in the result_modifier.php of the template, get a list of sections and additionally request the data for this field, and then get direct links to files through CFile.
