Persistent Variables

[maliary]

 

 

Hi,

 

I have this variable that is passed in the the $_GET, which I then assign it to a $_SESSION variable to ensure persistency, however every time i reload the page the $_SESSION variable gets lost. Hence unusable.

 

$_SESSION ['very'] = $_GET['pery'];

 

How can I ensure persistency beyond page reloads?

Try

if (!$_SESSION['very'])
{
if ($_GET['pery'])
  {
   $_SESSION['very'] = $_GET['pery'];
  }
}

In any page you want to use that session variable....

<?php

  session_start();
  $very = $_SESSION ['very'];

  echo $very; //Should still output a value even on diferent pages;

?>

 

Though you can also look into constants....doing this once....it has been defined and it's value won't change....so it depends on your script and logic in terms of what approach would be best.

 

<?php

  define('VERY_DEFINED', $your_value);

?>

 

Edit: But you must initiate the session (session_start()) before using the session variable in other pages.
