Multiple File upload - need help with validating file size

[izbryte]

Hello! I have this validation script that seems to work great until I add the size validation. I'm ready to pull my hair out! Can someone tell me what I'm doing wrong?

 

if (isset($_POST['Submit'])) {
$user_id = $userdata[user_id];
    $number_of_file_fields = 0;
    $number_of_uploaded_files = 0;
    $number_of_moved_files = 0;
    $uploaded_files = array();
$max_filesize = 5242880; // Maximum filesize in BYTES (currently 5MB).
    $upload_directory = dirname(__file__) . '/'.$user_id.'/'; //set upload directory
if (!is_dir($upload_directory)) {
    mkdir($upload_directory, 0777, true);
}

    for ($i = 0; $i < count($_FILES['images']['name']); $i++) {
        $number_of_file_fields++;
        if ($_FILES['images']['name'][$i] != '') { //check if file field empty or not
            $number_of_uploaded_files++;
		if($_FILES['images']['size'] > $max_filesize){
			echo "<b class='red'>Max file size is 5MB.</b><br/>";
			$sz = true;
		}
		$ext = validate_extension($_FILES['images']['name'][$i]);
		if (($ext == true) && ($sz == true)){
			$uploaded_files[] = $_FILES['images']['name'][$i];
			if (move_uploaded_file($_FILES['images']['tmp_name'][$i], $upload_directory . $_FILES['images']['name'][$i])) {
				$number_of_moved_files++;
           		 }
		}else { echo "<b class='red'>File extention error. Only .doc, .pdf, .jpg and .gif files are allowed. </b><br/>";
		}

        }

    }
if ($number_of_uploaded_files >= 1){
	echo "Number of files submitted:<b class='red>".$number_of_uploaded_files."</b><br/>";
	echo "Number of successfully uploaded files:<b class='red>".$number_of_moved_files."</b><br/><br/>";
	echo "Uploaded File Name(s):<br/>" . implode('<br/>', $uploaded_files);
}


}

 

As of now it results in every uploaded file returning the error "Max file size is 5MB."

You should add some debugging into that message to narrow down the issue.

 

echo "<b class='red'>Max file size is 5MB.</b><br/>";
echo "Debug: {$_FILES['images']['size']} > $max_filesize<br>";

 

See what that returns. If it's not what you expect, you should verify that you are using the array correctly.
