I just downloaded and installed the poll becasue I want to quit using the Bravenet poll that I currently use. I changed permissions as per the readme file. But when I access mydomain/poll/admin I get the following errors:

Warning: fclose() has been disabled for security reasons in /home/obsessed/public_html/poll/include/class_template.php on line 75

Warning: Cannot modify header information - headers already sent by (output started at /home/obsessed/public_html/poll/include/class_template.php:75) in /home/obsessed/public_html/poll/admin/common.inc.php on line 15

The login box shows below that but a graphic is missing. Please help!

Thank you

fclose has been banned but not fopen :-/ really stupid security that one. I came across this problem with the guestbook on some servers and the fix is easy. I'm about to hit the sack after a 12 hour night shift so will look at the code later. So long as it's only the template stuff I should be able to replace the fopen, fread, fclose bit with just file_get_contents

Sorry forgot all about this busy and all that

Open class_templates.php

replace


with


Should work but as I haven't tried it no promises.

That worked! But now, on the next page I get the errors below:

What should I substitute there?

At a guess the same thing that is in class_templates.php exists in class_session.php. Open it in a text editor and look for the same as before.

That file is a little different. The error is from the fclose in this chunk of code (below). How can I fix this one? Thanks!!

function generate_new_session_id($user_id) {
srand((double)microtime()*1000000);
$session = md5 (uniqid (rand()));
$unix_time = time();
$config="<?php\n";
$config.="\$auth['session']=\"$session\";\n";
$config.="\$auth['uid']=\"$user_id\";\n";
$config.="\$auth['expire']=\"$unix_time\";\n";
$config.="?>";
$fp = fopen("$this->include_path/session.php","w");
flock($fp, 2);
fwrite($fp, $config);
flock($fp, 3);
fclose($fp);
return $session;
}

Ah you are using the text version of the poll. This could be a problem. Let me look into it. Still say it's weird locking fclose but not fopen.

I have emailed my hosting company about why they are disabling fclose, have not heard back yet. Thank you for any work-around you can provide.

Thanks for any help.

My hosting company is giving me the run-a-round.
Is there a fix for this fclose being disabled?
Can I use something else instead?
And, please be patient with me, what happens if I just delete that line(s) and don't fclose at all (will it work)?

I'm trying to see if there is a different way to write to files.

Thank you, that would be great. Another developer told me that he thought, that anything that I did an fopen() for, would automatically be closed when the script terminates. Other than sloppy coding, is this true?

But yes, it there is a better way that is fine too.

In theory yes. But it may end up corrupting the file in some extreme cases. Make a regular back up of the files and you should be ok.
