Answer 1

I have struggled with this dilemma for almost a week! Nothing I found on the net could help me. I knew sort of what to do, but could not figure out how to loop through the $_FILES array properly - until now when I read the edited post of the accepted answer.

I made some changes though, in the script as posted, as it did not work properly for me. I wanted to be able to determine if a file was selected at all, so I changed the line "if( !empty( $_FILES[ 'image' ][ 'error' ][ $index ] ) )" to "if( !empty( $_FILES[ 'image' ][ 'size' ][ $index ] ) )" and then instead of "return false;", I put the size into a variable instead: "$Size = $_FILES[ 'upload' ][ 'size' ][ $index ];"

This way I could check if the $Size variable was larger than zero. If it was, then a file had been selected and I could continue with counting the number of files and do the actual upload. I did not use any of the "unnecessary" script after "return false;", in the accepted answer. Hope this helps someone.

Maybe:

Main photo:   <input type="file" name="image1" />
Side photo 1: <input type="file" name="image2" />
Side photo 2: <input type="file" name="image3" />
Side photo 3: <input type="file" name="image4" />

$i=1;
while (isset($_FILES['image'.$i])) {
    print_r($_FILES['image'.$i]);
    $i++;
}

If you have to loop through specific file fields.
