As long as you have session_start() at the beginning of each script, $ses_username is
now available across scripts.

Please, please, PLEASE don't give advice! If you don't know the answer,
DON'T COMMENT! The method you posted is for register_gkobals on, which
it won'tr always (and shouldn't be)!

The method you posted is for register_gkobals on, which it won'tr always (and shouldn't be)! /snip No need to be rude ... its very easy to adjust this code so that it doesn't need register_globals. The logic of the code is the point. I simply offered an alternative way of handling session vars that I feel is cleaner and clearer. Please don't go off the deep end with replies. There's no need. If you felt that you should point out the register_globals issue, then a simple 'Don't forget register_globals needs to be turned on here and it probably isn't' would suffice. While I am not a php guru (as you seem to be) I have been working with it for a long time commercially and do have some experience, so I am occasionally able to offer pointers on people's questions and offer such advice freely, in the hope that it will help. Lets all be adults, shall we ? You don't get any points for flaming. We're here to learn not fight. snip Ronan Chilvers wrote: Coments inline... snip On 01 Apr,2003 at 10:04 Mustafa Ocak wrote: You can store the value in a session variable /snip -- Ronan e: [EMAIL PROTECTED] t: 01903 739 997 w: www.thelittledot.com The Little Dot is a partnership of Ronan Chilvers and Giles Webberley -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Hi Leston
In case Leif, doesn't get back to you, here's a way to do it (inline). Similar to what
Mustafa has already posted:-

You can shorten $HTTP_SESSION_VARS to $_SESSION if PHP version 4.1.0.

Re: [PHP-DB] Sharing variable values among PHP files
You can store the value in a session variable
session_start();
if (isset($_HTTP_SESSION_VARS['your_variable_name'])) {
$value=$_HTTP_SESSION_VARS['your_variable_name']; //get the value
}else{
$_HTTP_SESSION_VARS['your_variable_name']=new value;
}
You can use this script to pass values between pages.

Does anyone know how to take a variable containing POST data from a form
and use this value in another PHP file? I need to take a username from
one PHP file and use it in a couple of other PHP files later when adding
to a database.
Thank you,
