userid on all pages

[kadamsurekha]

hi friends!

i m designing a website wherein user first login to the site.

once he login he can access the other pages.

i want the username to be displayed on all the pages till he logouts.

 

but i m getting the username displayed only on the second page.

 

my code is as follows:

 

<?

$emailID=$_POST['username'];//username

$passwd=$_POST['passwd'];//password

include("config.php");//set the connection

include("opendbs.php");//selects the database

 

include("getuser.php");//validates the user

if($flag)

    include("secondpage.php");//second page opens

else

                  include("notexistpage.php");

                  //msg not existing user gets displayed

?>

 

 

i get the emailID displayed only on the second.php page n not on later pages.

wht should i do to get this work?

 

thx n regards

Place session_start() at the top of every page before anything

yes do that but you can also use sessions to store the username/id

[shaunrigby]

<?php //don't use quick tags
   $emailID=$_POST['username'];//username
   $passwd=$_POST['passwd'];//password
   include("config.php");//set the connection
   include("opendbs.php");//selects the database
   
   include("getuser.php");//validates the user
   if($flag)
        include("secondpage.php");//second page opens
   else
                  include("notexistpage.php");
                  //msg not existing user gets displayed
?>

 

in ur getuser.php page upon successful validation use

$_SESSION['uid'] = $userid

 

Then on everypage that you want the userid to appear on start the page with

session_start()

and where you want the username to appear type

print "Welcome, " . $_SESSION['uid']; 

however you will need to use an if statement to determine if the session variable has been set eg;

 

if(isset($_SESSION['username'])){
     print "Welcome, " . $_SESSION['uid']; 
} else {
    print "Welcome to foobar.com, please <a href=\"login.php\">Login</a> or <a href=\"register.php\">Register</a>";
}

Try not to use the session liek that:

$userid= $_SESSION['uid'];
