picture form field doesn't understand !$_POST

[calmchess]

I have a form field that uploads a picture but when i say in my script

if !$_POST['pic'] in order to send an error message if the field is empty then it always comes back as being empty is there something else i need to use for the file type? or how do I ask a field if its empty or not?

You probably need to read the upload section in the php manual or read an upload tutorial to get the basic information needed to do this because the uploaded file is not available in a $_POST variable.

I looked at the manual but all i could find is $_FILES but it always returns ARRAY.....don't know how to say if !$_FILES then give error message. could you help with a code example.

the $_FILES var is exactly what you need. it is indeed an array which you can use for validation.

well i managed to echo the array using print_r $_FILES['uploaded']; but i cannot figure out how to access each slot in the array so i can run an if statment on it...anybody have any more input?

I'd suggest starting at looking into how arrays work not difficult once you get the basics.

I trie $_FILES[0]; but that returns nothing

nevermind i figured it out ....this is a multidemsional array to me $_FILES['uploaded']['name'];
