Question

I have file $fileImage = $_FILES['fileCatImg'];, everything works when I try to upload it, but how do I check if file is selected first? if (isset($fileImage)) and if (empty($fileImage)) are not working. One of them always returns true value, but other always returns false value.

Answer 1

Check file size:

if($_FILES['fileCatImg']['size'] > 0) { ... }
