PHP and $_SESSION

[JJohnsenDK]

Hey

 

When i make a $_SESSION['test']; should it "be alive" until i kill it with unset()?

 

Because my code doesnt act that way.

 

I have multiple form submits on my page and to remember the data from every form i use sessions. But the session only "survives" doing the one form submit.

 

Here is some of the code:

 

if(isset($_POST['submit_area'])){
    $_SESSION['area'] = $_POST['area'];
}

if(isset($_POST['submit_aktivitet'])){
    $_SESSION['aktivitet'] = $_POST['aktivitet'];
}

 

Here $_SESSION['area'] only lives when i have click the submit_area button.

I have set session_start(); i top of the code.

 

Whats wrong?

Have you tested a simple session page to make sure sessions are working correctly?

[JJohnsenDK]

How do i do that? Because i cant see what should make what i have made here, a more simple session page

[revraz]

page1.php

 

<?PHP
session_start();
$_SESSION['test']="Hi";
?>

 

page2.php

 

<?PHP
session_start();
echo $_SESSION['test'];
echo " there";
?>

 

Run page1.php, then run page2.php and it should echo "Hi there"

i see where are going with this, but its not the problem, because i declare ohter sessions with there are no problem with. Im gonna post the code:

 

$_SESSION['area'] echos just fine when i click first 'submit_area' button, but when i click 'submit_aktivitet' button i cant echo anymore, but then i can echo $_SESSION['aktivitet']. And again if i click the last submit (which brings me to a new page) i cant echo $_SESSION['aktivetet'] nor $_SESSION['area'] ??
