changed server

[jalea148]

After changing servers from a php4 server to a php5 server, post data was being lost. When phpinfo() was inserted into the code, here's part of what emerged:

DOCUMENT_ROOT /home/content/r/i/c/old_server_directory/html
PHPRC /home/content/r/i/c/old_server_directory/html
SCRIPT_FILENAME /home/content/r/i/c/old_server_directory/html/Q_FORMsmall_2a.php
SERVER["DOCUMENT_ROOT"]/home/content/r/i/c/old_server_directory/html
SERVER["PHPRC"]/home/content/r/i/c/old_server_directory/html
_SERVER["SCRIPT_FILENAME"]/home/content/r/i/c/old_server_directory/html/Q_FORMsmall_2a.php

Most file references were to the new_directory. How are the old_server_directory references corrected?

Also, the following error starts appearing - will it go away or is it suggesting other errors?

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /home/content/r/i/c/old_server_directory/html/Q_FORMsmall_2a.php:2) in /home/content/r/i/c/old_server_directory/html/Q_FORMsmall_2a.php on line 3

The session error you're seeing will go away once you move session_start to be above all output (including white space).

As for the other items, I think document_root can be modified in php.ini; although, I'm not sure of too many servers that actually use it.

Thank you regarding the error messages going away. I didn't see any references to old_server_directory or Document_root in php.ini. Maybe I'm going in the wrong direction. My real problem is $Post is null.
<?php
session_start();
phpinfo();
if (isset($POST['First'])) {
$SESSION['sessFirst'] = stripslashes($POST['First']);
}
if (isset($POST['Last'])) {
$SESSION['sessLast'] = stripslashes($_POST['Last']);
}
?>
