page validation

[ypran]

I have written the php code for login and redirected page. When the user logout from his account and if he clicks back button then i need to check whether the user is logged in or not? How can i make the page validate on back button hit?

Hi

 

I really don't know what u mean by "How can i make the page validate on back button hit"

 

but you can manage your login using sessions and/ or cookies.

 

Get back if you run into trouble

Yep as said above, ull need sessions or cookies to handle login state. So a simple example should be:

 

login

<?php
session_start();
if($login){ //this is your login validation
    $_SESSION['login'] = true;
} else{
    echo 'The username and password are incorrect';
}
/>

 

session check on other pages

<?php
session_start();
if(isset($_SESSION['login'])){
    //show some info
} else{
    die('You must be logged in to access this section');
}
?>
