using session_start() and then $_SESSION['customer'] = 'max' like this
forwarding it to next page , but there is a problem like when i use back link on
the page and try to retrieve the values through session but it doesn't work
it didn't show any values

What do you mean by back link?

What do you mean by back link?

its basically a link to go to the previous page.

well maxjackie, instead of writing this code

[PHP]$_SESSION['customer'] = 'max';[/PHP]
u can write

[PHP]if(! isset($_SESSION['customer'])) {
$_SESSION['customer'] = 'max';
}[/PHP]
this will solve ur problem.
