Hello,
I need your help. The script that i have below is intended to upload files. The max upload file size is 1mb. If the size is greater than 1mb, it is supposed to return with an error message displayed.
I tried upload files less then 1mb and it works fine.. however, if i try to upload say a 2.5 mb file, it crashes. I wrote some echo statements to help me decode it but really can't figure it out. Echo statements were placed inside checkMaxMemorySizeLimit()
I am not using this because i read it doesn't work on IE 6 and stuff..
<!-- MAX_FILE_SIZE must precede the file input field -->
<input type="hidden" name="MAX_FILE_SIZE" value="30000" />
I really want the checks to be done in my php first and then i'll add the above later...

$fileupload->uploadFile();
$errStack_register = $fileupload->validateUserInput();
}
if ( count($errStack_register) < 0){
header('Location: invitefriends.php');
