I'm having this kind of Error stated below, I don't understand completely about it. If I press upload button without selecting files!
Notice: Undefined index: $error in C:\wamp\www\btb_sandbox\upload_2.php on line 35

<?php
// The maximum file size (in bytes) must be declared before the file input field
// and can't be larger than the setting for upload_max_filesize in php.ini.
//
// This form value can be manipulated. You should still use it, but you rely
// on upload_max_filesize as the absolute limit.
//
// Think of it as a polite declaration: "Hey PHP, here comes a file less than X..."
// PHP will stop and complain once X is exceeded.
//
// 1 megabyte is actually 1,048,576 bytes.
// You can round it unless the precision matters.
