File upload problem

Hi All,

I've written a simple script to upload a file as part of a form.
Everything works fine on my system (win32, apache2, php4.3.1). However,
when I upload the script to my host (linux, apache1.3, php4.3.2) it appears
to have a file-size related issue.

I can upload via a form ($_POST) and everything works as expected with
files below approximately 500bytes. Any larger than this and I instantly
get a "Cannot find server" error page.

I have checked the relevant globals and settings on the host setup, with
phpinfo(). Max post size is 4M, max memory is 8M. The rest of the post
data is plain text of about 2k maximum.

Any help appreciated.

Check the value behind 'upload_max_filesize' in the output of phpinfo,
perhaps there is something wrong here.

Also, when you use the max_file_size hidden field in your upload form,
remove it and see what happens then.

how does the form and the script receiving data look like?

This is set to 4M, the same as max_post_size. I cannot change this value.

Max_file_size was set to 10000. Removing the <input /> tag had no effect.
Increasing the value to 1000000000 had no effect either.

Please bear in mind that the script works OK for small files, but fails for
large (500byte) files. Also, that the error is a plain old 'Cannot connect
to server'.

The section of form looks like this:
<form enctype="multipart/form-data" action="index.php?page=observer
&amp;action=editperson&amp;key=12" method="POST">
<input type="hidden" name="MAX_FILE_SIZE" value="1000000000" />
<input name="form_file" type="file" />

And the receiving script looks like:
if($_FILES['form_file']['tmp_name']!="")
{
echo $_FILES['form_file']['tmp_name']."<br />"; //debug
echo $_FILES['form_file']['name']."<br />"; //debug
$file_extension = strrchr($_FILES['form_file']['name'],'.');
echo strtolower($picname = "/observers/images/" . //echo is debug
strip_tags($_POST['form_firstname'] .
"_" . $_POST['form_surname']) .
$file_extension);
if(move_uploaded_file($_FILES['form_file']['tmp_name'],$docroot.$picname))
{
echo "<p>Success!</p>";
}
else echo "<p> failed to move uploaded file</p>";
}

You are validating my inherent mistrust of strangers.

I had the very same problem a few days ago, and it was about a configuration
on the Apache server.

I know how to code, but know almost nothing on Linux/Apache configuration,
and I was not the one who fixed the problem.

All I know is that a configuration file that sets the maximum upload size
was changed and everything worked fine then.

Sorry for not being of great help, but I hope this info be useful.

Unfortunately it looks like the max_file_size is set correctly.

Thanks for your help anyway.

I'll give you a quid if you promise not to reproduce

Problem found, but not resolved!

My ISP (ntl) has a transparent proxy between me and the rest of the world.
Apparently this is malfunctioning causing any POST data to be limited to
0.5KB.

I have managed to specify a proxy server other than the malfunctioning one,
and all is well again.

Thanks to all for their assistance.

The upload_max_filesize is 4M. I could not upload anything over 0.5kbytes.
The problem was eventually traced to my ISP's transparent proxies
malfunctioning and not allow any POST data over 0.5kbyte to be transmitted.
Strange error, but bypassing the proxies has cured my problem.
