session variable values are lost when redirecting

[benoypaul]

I have created a php script for login using session variables in php . After checking the login information , I redirected to another page using following scripts

          $username="valid";
    session_start();
    session_register("username"); 
           echo "<script>";
           echo " self.location='loginvendor.php' "; 
           echo "</script>";
 
In target page ,  value of session variable was lost. I have used following  code in target page(loginvendor.php)
 
if(strlen($_SESSION["username"])<=0)
{
header( "Location:  index.php" );   
}
 
 

Due to this session variable problem , I was redirected to index.php in every time.

I do not know how to correct above error. Plz help

hi benoypaul

session_registe r is a deprecated function and will not work when register_global s is off (which is propably is). Use $_SESSION when setting your session var. this should work.

for more info see http://www.php.net/manual/en/functio...n-register.php

Heya, benoypaul.

Please use CODE tags when posting source code. See the REPLY GUIDELINES on the right side of the page next time you post.

the logic behind the login is quite simple. first collect the login details(usernam e and password)
secondly only start a session on successful authentication of the user. now create session variable to hold whatever data u want to have access to on other pages.

after u must have done all these all u have to do is start a session on the redirect page if one is not already started and reference the session variables.
