How do i make max_upload file more than 2mb?

In the form have a hidden element

<input name="MAX_FILE_SIZE" value="30000" type="hidden">


and this to the section that handles the php upload Code:

ini_set ("post_max_size", 30000);
ini_set ("upload_max_filesize", 30000);

of course set 30000 to your desired maximum files
