Hey. This code works in many browsers, as well as partly in IE6. It uploads files less 10Mb (roughly), although not anything bigger. The code identifies that individuals files are allowed.

Also, observe that it appears such as the entire file appears to become moved towards the servers before disregarded.

The web site reaches: www.mgxvideo.com/mgxcopy-alpha-3/ and may be arrived at with the addition of a product within the trolley, after which clicking the upload function. Ideas?

This is actually the form:

<form enctype="multipart/form-data" action="upload_files.php?order_id=<?php echo $_GET['order_id'] ?>" method="POST">
    <table style="width:100%">
        <tr>
        	<td valign="top">
        		<span class="style1">Choose a file to upload: </span> 
        	</td>
        	<td valign="top">
        		<input name="uploadedfile" type="file" />
        	</td>
        </tr>
    </table>
    <input type="submit" value="Upload File" />
    <input type="hidden" name="action" value="add"/>
    <input type="hidden" name="MAX_FILE_SIZE" value="100000000" />
</form>

This is a line towards the top of upload_files.php:

$upload_output = upload_file($customer_id, $_REQUEST['action'], $_GET['order_id'], $_FILES);

Here is the upload_file() code:

function upload_file($customer_id, $action, $upload_id, $FILES)
{
	$target_path = "uploads/";

	$target_path = $target_path . $customer_id . '_' . $upload_id . '_' . basename( $FILES['uploadedfile']['name']); 
	$str_output = '';

	if ($action == 'del' and file_exists($_POST['filepath']))
	{
		delete_file($customer_id, $_POST['filepath']);
		$str_output = '<span class="style1">File successfully deleted. If you are done uploading files, ' .
				'<a href="#" onclick="self.close();">click here</a> to close this window.</span>';
		setcookie("upload_out_txt", $str_output, time() + 300);
		setcookie("upload_out_b", "1", time() + 300);
	} else if ($action == 'add')
	{
		if (count_uploads($customer_id, $upload_id) >= 2)
		{
			$str_output = '<span class="style1">Problem: You have reached the maximum allowed uploads for this particular order. Please delete a file before continuing.</span>';
			setcookie("upload_out_txt", $str_output, time() + 300);
			setcookie("upload_out_b", "1", time() + 300);
		} else if (file_exists($target_path))
		{
			$str_output = '<span class="style1">Problem: A version of the file you are trying to upload already exists. Please delete the file from out servers before uploading again.</span>';
			setcookie("upload_out_txt", $str_output, time() + 300);
			setcookie("upload_out_b", "1", time() + 300);
		} else if (move_uploaded_file($FILES['uploadedfile']['tmp_name'], $target_path)) 
		{
			insert_to_database('uploaded_files', array($customer_id, $upload_id, 'now()', $target_path));
			$str_output = '<span class="style1">Success. The file was successfully uploaded. If you are done, <a href="" onclick="window.close();">click here to close the window</a></span>';
			setcookie("upload_out_txt", $str_output, time() + 300);
			setcookie("upload_out_b", "1", time() + 300);
		} else
		{
			$str_output = '<span class="style1">There was an error uploading the file, please try again!</span>';
			setcookie("upload_out_txt", $str_output, time() + 300);
			setcookie("upload_out_b", "1", time() + 300);
		}
	}



	return $str_output;
}

Here's my php.ini file, once i attempted to implement a fix:

extension_dir="/kunden/homepages/30/d93769495/htdocs/extensions";
extension=uploadprogress.so;
upload_max_filesize=150M;
post_max_size=210M;
max_input_time=1800;
file_uploads=1;
memory_limit=240M;
max_execution_time=1800;

This might not repair it but on a single thread i had been reading through it stated that IE6 must process the MAX_FILE_SIZE line prior to the filename input. So try moving the next line to the top form:

<input type="hidden" name="MAX_FILE_SIZE" value="100000000" />

I've no clue whether it works and IE6 requires so that it is parsed for the reason that order, but that's exactly what the thread I had been reading through stated the answer was.

Also look at your php.ini max quality and timeout.
