Okay, so basically i need a little helpt with some validation code.
I need to see if the user has actually selected an image, if not, $error = 1;.
I tried this:
if($_FILES['image']['name'] == "") {
echo 'Error: Select an image!';
$error = 1;
}I tried several times to put the code in with the rest of the validation code (image size, extension etc.), but it wont work. Once i try to upload with empty image field it says: Error: Select an image!File uploaded successfully!. And there are errors at line 119.
If anyone has time to help me, i will be pleased, it also would be good with a little explanation why this does not work.
