PHP Session

NZ_Kiwis

I've got a basic online shop, I want set a cookie or PHP session when a user visits my site... so that when they click add item it will add the item to an array or items that they want a quote on...

How can I do this?

Session Handling (PHP manual)

Here's a fairly short tutorial to cover the basic usage: http://www.tizag.com/phpT/phpsessions.php

Why does this not echo the session then??

<?php

session_start();
session_id();


$sesion_id = session_id();
echo $session_id;
?>

NogDog

Because you misspelled $session_id on the penultimate line of code. 😉

Oh crap. Cheers mate

Also, can I have a session_name called $SESSION['cart'] which is an array? this can carry all the product codes someone wants a quote on

NogDog

Yes. Other than the fact that it is "super-global" and that you should avoid ever unsetting the entire array, you can treat it just like any other array in PHP.

Soo

$cart();
$SESSION['cart'];

Would work???

Well, that's not exactly syntactically correct. But you could do:

$cart = array();
$cart[] = array('id' => 1234, 'qty' => 5); // add one item to cart;
$cart[] = array('id' => 4532, 'qty' => 2); // add another item
// now save entire cart in session data:
$_SESSION['cart'] = $cart;

Great that works wonder, can do array count, empty the array (cart)

How do I add to the cart (array) and keep the rest there... i know how to add items once but not go back in and add more....

the $SESSION array is the same as any other array (well, almost), so you can use:

$_SESSION['cart'][] = 'new item name/id/whatever';
count($_SESSION['cart']);

Will work along with pretty much any other array function - I have never come across one that you can't in my time using PHP. For reference, here is the PHP official array function manual:
http://php.net/manual/en/ref.array.php
and the section for sessions:
http://php.net/manual/en/book.session.php

Plenty of stuff to keep you busy there!!

And how do I print the 3rd result in the array for example?
