PS: it happens only when I load a video, works well when I upload photos, any help would be welcome

Answer 1

About halfway down your code, you have:
// Valid file extensions
$extensions_arr = array("mp4","avi","3gp","mov","mpeg");
// Check extension
if (in_array($videoFileType, $extensions_arr)) {
if (($_FILES['video']['size'] >= $maxsize) || ($_FILES["video"]["size"] == 0)) {
// do stuff
So your code is checking if the file you've uploaded has any of the extensions in $extensions_arr (.mp4, .avi, .3gp, .mov, .mpeg).
Once you've uploaded the file, it then checks the size and makes sure it's not either 0 or greater than the max file size. As an aside, to make this a little bit more readable, why not just use
if (in_array($videoFileType, $extensions_arr)) {
if (($_FILES['video']['size'] <= $maxsize) || ($_FILES["video"]["size"] > 0)) {
// do stuff
and check that the file size is less than max size but greater than 0?
The problem here is that you haven't declared $shop anywhere in the code, maybe you meant $target_file?
