feel stupid and I have to ask...phpftp question

I'm trying to test out the phpftp client found here:

http://inebria.com/phpftp/

It's open source software, and I've tried about all the other alternatives. I'm certain I have met all the requirements listed but I'm not having any luck. Basically, when I submit the form, it just comes back with the same form and all the fields are blank. I'm sure it's something simple, but it's making me crazy. I'm running apache 1.3x and php 4.3x on FreeBSD 4.10. The ftp.php file is located in the root of the webserver dir (/usr/local/www/data/ftp.php). Any help or insight is appreciated. The full PHP script is below.

NezzoCommented:
It's probably a problem with your ftp server. First, make sure you can ftp into it normaly from the command line. If that's working fine then try this:

In the script you will see @ signs place here and there. They are there to stop PHP error messages from being displayed or logged. Remove all @ signs and try again.

For example, this:

<!-- function phpftp_list -->
<?php
     $ftp = @phpftp_connect($phpftp_user,$phpftp_passwd);
     if (!$ftp) {
?>



would become:

<!-- function phpftp_list -->
<?php
     $ftp = phpftp_connect($phpftp_user,$phpftp_passwd);
     if (!$ftp) {
?>


Remove the rest of the @ signs in the script and try it again. Your errors will be displayed in the browser or in your apache error log.

Also, did you check your apache error log for errors?

Another thought. :)

Thanks Nezzo. I do  have the /var/tmp/xfers directory in place and with the correct permissions (as you stated). There is nothing in the httpd-error.log. The access log shows a get and a post entry....but nothing else. Anything else?

thanks again,
Tim

What kind of ftp server are you running? The reason I ask is you have $phpftp_host set to "localhost":

$phpftp_host="localhost";

the server is vsftpd? I'll take a look at the conf file...hmmm

Nothing out of the ordinary from what I can see. There doesn't appear to be a entry for hostname in my vsftpd.conf file (not even sure if there should be?)

timmr72Author Commented:
I actually went a different route. The variables weren't passing from one page to the next for me in this script. Still don't know why. Found a different solution that worked immediately (Net2FTP). Thanks though. You can have the points for being the only one to attempt to help :).
