Doesn't Work

[Dysan]

Why doesn't the following code work.

 

I'm trying to test if an array exists, to insert data into it, else create the array. Only each time I access the page, the array contains no data. Why is this?

 

<?php
session_start();

$id = $_GET['id'];
$array = $_SESSION['ids'];
if (!isset($array))
{
$array = array();
}
else
{

$array[] = 'Data';
$_SESSION['ids'] = $array;
}


echo $_SESSION['ids'];

print_r($array);
?>

You have problems with your logic.

 

I think this will do what you're trying to do:

<?php
session_start();
$id = (isset($_GET['id']))?$_GET['id']:'';
$array = (isset($_SESSION['ids']))?$_SESSION['ids']:array();
$array[] = $id;
$_SESSION['ids'] = $array;
echo '<pre>$_SESSION:' . print_r($_SESSION['ids'],true) . '</pre>';
echo '<pre>$array:' . print_r($array,true) . '</pre>';
?>
