 New Comment:

Profuse apologies!  After another round of inspection, the module in
question was actually the Win32 mod_gzip, which would totally botch the
variables (as noted and fixed in the v1.3.26.1a changelog).

My sincerest apologies.  I thought I was working with a vanilla
system.

I hope this helps anyone with similar problems.

Doesn't seem to fix it.  Still returns "no filename."

I also tested this on Windows 2000 SP3.  Same Apache and CVS PHP. 
Similar results.

(additionally, I made a mistake in the earlier post.  It's 1 to 2K, not
1024K)

Please try using this CVS snapshot:

  http://snaps.php.net/php4-STABLE-latest.tar.gz
 
For Windows:

* Windows NT SP6a with all the patches

* Apache 1.3.27, PHP 4.3.1 as a module.  Mostly "reccomended" php.ini
settings.

* Using the zip binary.

When using the code below, I get the "no filename" message, indicating
that the POST variables have disappeared when the textarea is filled
with over (aproximately) 1024K worth of data.  To reproduce, I used a
single character to fill the textarea.

The post_max_size has not been altered from "8M", neither have any
other such variables.  No LimitRequest* variables have been set in
Apache's httpd.conf.


test.html------------------------------------------------

<html>
<body>
<form method="POST" action="bug.php">
<input type="hidden" name="filename" value="the file name">
<textarea rows="20" cols="80" name="contents">
</textarea><br>
<input type="submit" value="Save">
</form>
</body></html>

bug.php--------------------------------------------------

<?

if ( ! empty($_POST["filename"]) ) {
	reportError("No error");
} else {
	reportError("No filename");
}

function reportError($err_str) {
	if ($err_str == "" ) $err_str = "Unspecified";
	echo "<html><body>\n";
	echo "<h3>$err_str</h3>\n";
	echo "</body></html>\n";
}

?>
