Hello everyone! Before I start let me just say that ive read many threads on here about php and sessions, several tutorials and the php manual but I still cant find a solution to my problem. My problem is that when i try to read data from a session it just comes up blank, and an if statement to see if the variable is null returns true. The code im using is for a login script which checks the input from a user and compares it with the data in a database to log the user in, this works fine, also reading the data from the session works perfectly on the page which the session is generated by so the problem is when the user navigates to another page the variables dont seem to travel with them. The code I'm using to generate the sessions is this: QUOTE //define initial variables $user = $_POST['username']; $password = $_POST['password']; session_register(name,$user); session_register(status,"0"); //set variables $session['name'] = $user; $_session['status'] = "0";
to try and read the variables from another page ive used an included file with thise code: QUOTE session_start(); if($_session['name'] == NULL){ echo "no session is set  <BR><BR>"; echo $_session['name']; } else { echo "sesion is set for:"; echo $_session['name']; }; This returns "no session is set" which means that the variable is null. the data inside the session file is "name|N;chris|N;status|N;0|N;" I dont know if that helps to see what the problem is. So can anyone tell me why the variables aren't being read by the pages?

The superglobal for sessions is $_SESSION not $_session or let alone $session. Latter two are just normal arrays created when you assign values to them. So change the lines CODE $session['name'] = $user; $_session['status'] = "0"; To CODE $_SESSION['name'] = $user; $_SESSION['status'] = "0";
And your script should work. Also you do not need to use session_register() function. Simply assigning values to the superglobal array ($_SESSION) suffices. Session_register() works but it's usage is not recommended anymore.

Letting Users Add Mysql Data With Php
(1) I'm curious as to the best methods of letting users submit data to a MySQL database, displaying
that data, and removing any unwanted tags etc. from it. Currently, there's a handful of PHP
functions that I know of to help with this: mysql_real_escape_string() - perhaps the best known
and most commonly used function, it should be used in pretty much any MySQL query. It escapes
characters that have SQL significance. QUOTE(php.net) ...which prepends backslashes to the

Getting Certain Parts Of A Record
The character data (17) Ok I need help on this puzzling problem. At first I thought that this person stored the dates in the

are hard to manipulate. Then I found out that he stored both th string data and numerical date,

Proper Way To Grab User Data?

mysql_fetch_array(mysql_query($sql)); //Link the two tables together; grab the most common thing
