explorer and firefox

nuttynibbles

hey guys out there, i've got a weird problem. See i've a page where it uploads image. Once submitted, it will call uploader.php where it check for error. if there's an error, it will be redirected to error.php However this works in mozilla firefox and NOT in explorer.. WEIRD!! :glare: k ive found the source of the error which cause it not to work in explorer?

here is the code:
<HTML>
<HEAD>
</head>
<form name="form1" enctype="multipart/form-data" action="uploader.php">
<input type="hidden" name="MAX_FILE_SIZE" value="1000000" />
<input type="submit" name="Submit" value="Submit">
............
<input name="uploadedfile" type="file">

......
</html>

refering to the above code, the line of code which is highlighted in red causes the problem. This line of code was suppose to validate the image uploaded size(ie:1M😎

A) 1 MB is actually 1048576 bytes :-P

😎 This feature appears to be completely unsupported by internet explorer, as well as opera (at least as far as I can tell from my research).

C) Javascript limitation is also out, security measures require that no javascript can access local files (http://www.jguru.com/faq/view.jsp?EID=330134)

That's all I've got

The manual[/URL says, concerning MAX_FILE_SIZE:

The MAX_FILE_SIZE hidden field (measured in bytes) must precede the file input field, and its value is the maximum filesize accepted. This is an advisory to the browser, PHP also checks it. Fooling this setting on the browser side is quite easy, so never rely on files with a greater size being blocked by this feature. The PHP settings for maximum-size, however, cannot be fooled. This form element should always be used as it saves users the trouble of waiting for a big file being transferred only to find that it was too big and the transfer failed.

and

See also the file_uploads, upload_max_filesize, upload_tmp_dir, post_max_size and max_input_time directives in php.ini

BTW, the size of a MB depends on whom you ask; e.g. some hard disk manufacturers say 1,000,000 bytes.

so should I continue with using <input type="hidden" name="MAX_FILE_SIZE" value="1000000" />?? or wat should I do :bemused:

sorry guys ive been away for quite some time, im back on the proj... haha sad to say im still stuck at the uploading function. Let me recap..everything works fine in explorer except firefox. i tried some debugging and i oso find out that i can actually used <input type="hidden" name="MAX_FILE_SIZE" value="1000000" />.. but in uploader.php, i cant use header(); function. any idea why?

here is the code for uploaded.php:

<?php
session_start();

if(!ereg("image",$_FILES['uploadedfile']['type']))
{
	//header("location:Function/error.php");
	//echo "<b>File is not an image or the file size is too big";				
}
else if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $tempDir))
{
	header("location: order.php");
}
