Uploading images with PHP

Report · Sep 04, 2006

I have the following markup on my page -

<?php
if(isset($_POST['Submit'])) {
foreach ($_FILES["drawings"]["error"] as $key => $error) {
if ($error == UPLOAD_ERR_OK) {
$tmp_name = $_FILES["drawings"]["tmp_name"][$key];
$drawingname = $_FILES["drawings"]["name"][$key];
$userName = $row_rsUser['fuserName'];
//echo($tmp_name."-".$drawingname."-".$userName);
move_uploaded_file($tmp_name,
"../images/users/$userName/$drawingname");
}
}
}
?>
...
<form id="form1" name="form1" method="post" action=""
enctype="multipart/form-data">
<p>Upload New Images:</p>
<p>
<input type="file" name="drawings[]" />
</p>
<p>
<input type="file" name="drawings[]" />
</p>
<p>
<input type="file" name="drawings[]" />
</p>
<input type="submit" name="Submit" value="Send" />
</form>

And when I submit, I get this -

Warning: Invalid argument supplied for foreach() in
W:\Webspace\resadmin\madison\madisonconcrete.com\www\manage\m_users_update.php
on line 77

I'm tapped - any ideas?

i am not getting that error on my server. what version of php are you using?

Report · Sep 04, 2006

two other things:
I dont use it but they say that file uploads with php can fail with ie & ssl
http://support.microsoft.com/?kbid=889334
the result can be an empty $_FILES array. have you tried
print_r($_FILES) just to try to pinpoint the source of the error?

That's surely the problem - the array is empty. Hmmm - how is that
possible?

have you tried it with register globals turned on?

Report · Sep 04, 2006

No. And, I don't want to. It should work this way, no?

That will have no effect. The $_FILES array is one of the superglobal
arrays designed to eliminate the massive security hole created by
register_globals. Although some hosting companies still turn
register_globals on, anyone who relies on register_globals is living on
borrowed time. The default setting for the past four years has been for
register_globals to be off, and it has been removed entirely from the
forthcoming PHP 6.

If you have any scripts that rely on register_globals, bring them up to
date now - before it's too late.

Are you testing locally or on a remote server? If the latter, what is
the value of file_uploads when you run phpinfo()? File uploads may be
turned off on the server.

yeah, i do not rely on globals either. on php.net they did mention that some parts of the files array ar enot available with register globals off. it was a user comment, so maybe they were incorrect. i have not had issues with the same script on my server with register globals off.

Well, the bone I tossed you is to check the file_uploads setting with
phpinfo(). Another possibility is that the files are larger than
permitted by upload_max_filesize.

It's not, I know because my protoype page,
http://66.165.96.216/uploadtest.php works fine, as does another page I built
for the admin backend that uploads and resizes into 2 different thumbs.

Nope - neither of those apply, but thanks. I'm puzzled by the empty array -
it should be filled before any upload takes place, right?

i am not sure on this, but doesn't the file get uploaded to the temp directory first? i allways assumed this because it loads the $_FILES array with the temp name on the server, so the $_FILES array is the response from the server after it is uploaded right?

Yes, the $_FILES array contains details of what has been uploaded,
whether the upload was successful, and the location of the temporary
file. The important thing to understand is that the temporary file is
discarded if you don't move it to a permanent location before the end of
the script.

No, it's the result of the upload. I have tested the script you posted
here, and it works. There must be something else that is getting in the way.

Got it. The problem was that I was trying to send images from a networked
box rather than from the box on which I was testing. When the image is
truly local, it works! YIPPEE! I encountered this before, and forgot to
remember it! 8)
