Interesting problem with PHP file uploads

toastyman · 17 Dec 2007 at 22:10

Hey to all,

I'm currently trying to write a file uploader, but hit an interesting problem - some files just won't upload!

I've tried the following files:
testing.mp3 - 10.0mb (browser uploads it fine)
What About Bob.mp3 - 243mb (browser uploads it fine)
mix.mp3 - 10.1mb (won't upload)

When I say it doesn't upload, when I press the upload button on my form, the browser literally refreshes the page... it doesn't show the progress bar for a few seconds to indicate that it's uploading the file.

I've tried taking a few seconds off mix.mp3 and resaving it as a different filename (alters the filesize and ensures it's not corrupt), but still no joy.

The PHP page that receives the file:

Code:

print_r($_POST);
print_r($_FILES);

I get: Array() Array()

Here is the code for my form:

Code:

<form name="register" action="djenter.php" method="post" enctype="multipart/form-data">
<label for="djname">Your mix:</label><br />
<input class="inputo" type="file" name="mix" id="mix" value="Choose" />
<input type="submit" name="submit" id="submit" value="Submit my entry!" class="submito" />

I've also set upload_max_filesize to 15M in php.ini.

Anyone got any ideas / thoughts?

Cheers,
Rich

Do a php_info() and check all the server settings.

Are there any settings in particular I should be looking for? As far as I was aware upload_max_filesize was the only one which could affect file uploads...

max_post_size will affect file uploads aswell.

Sorry I think I gave you a red herring there.

What About Bob.mp3 - 243mb (browser uploads it fine)

Is that correct? 243mb?

Can you show us the php script that the form is posting to aswell?

Yeah. That's the file that's confused me. When you press the submit button, the page goes blank like it's uploading the file, and the status bar slowly progresses. It looks like PHP is accepting the file transfer.

I don't wait for it to complete the upload though, as it's only going to fail - upload_max_filesize is set to 16mb.

I've stripped the receiving PHP script down to just print_r($_POST); print_r($_FILES); at the moment, to ensure it's not that that's the problem.

Ahhh that is a valuable piece of info you didn't tell us!!!

Check the max_post_size.

I did in the original post

Aha good find! I didn't know that variable existed... it was set to 8mb. I've changed it to 16mb and all is fine and dandy!

Thanks very much

My pleasure, glad you got it sorted.
