kill only one session key and keep others

Gibou · 03-30-2008, 01:10 AM

Hi !

I currently use two sessions in my PHP5 API.
$_SESSION["user"] which contains the serialized instance of my "User" class. Allowing me to know who is the current visitor.
$_SESSION["tpl"] which contains the selected design.

I would like to destroy $_SESSION["user"] but keep $_SESSION["tpl"].
session_unset destroy all session data, session_destroy too, unset($_SESSION["user"]) doesn't work.

Here is my code:

PHP Code:


			
if(!empty($_POST['deco']) && $this->login != "none")

{

    unset($_SESSION["user"]);

    header("location:".((!empty($_GET['page'])) ? $_GET['page'].((!empty($_GET['id'])) ? "-".$_GET['id'] : "") : "").".html");

}

// the header is strange but works, I've well tested it.

Thank you for your ideas.

unset($_SESSION['user']) should work... strange

try

$_SESSION['user'] = '';

and then check it with empty()

Also check this topic out, about headers ;) The Dangers of the Header Function

PHP Code:


			
<?php

$_SESSION['user'] = "Orc";
$_SESSION['a'] = "this is a test"; # merely a test
function DeleteElement($input, $key)
{

    if (array_key_exists($key,$input))
    {

            unset($_SESSION[$key]);
            $tplArray = array('tpl');
            $new = array_fill_keys($tplArray,'my_templates');
            $_SESSION['tpl'] = $new['tpl'];
            print_r($_SESSION); # You can take this out if you want
        
    }
}


DeleteElement($_SESSION, 'user');

echo $_SESSION['tpl']; # Which gives you My_templates


?>

Okay, I came up with this function that deletes an element by key in the Array, this can definitely be improved cause its only adding a new key and val by what you said 'tpl' soo..

Try this, I don't even know if I did exactly what you requested.

Which gave me this:

PHP Code:


			

Array
(
    [a] => this is test
    [tpl] => my_templates
)
my_templates

Now I understand $_SESSION is an associative array, so fiddle with it.
