Removing Items from shopping basket

[almystersv]

Hi Guys,

 

Im creating a mock up of a stationary ordering system and have the add to basket function working fine but the remove from basket is not working.

 

Here is my code for removing items from the shopping basket..

 

<?php
session_start();
foreach($_SESSION['basket'] as $key => $product) {
	if ($_SESSION['basket'][$key]['URN'] == $_GET['URN'])
	{
		unset($_SESSION['basket'][$key]);
	}
}
header("Location: StationaryMain.php");
exit();
?>

 

Any help on this would be brilliant, thanks

I've no idea but the Manual says...

 

session_unregister

(PHP 4, PHP 5)

 

session_unregister — Unregister a global variable from the current session

 

might be worth swapping 'unset' for 'session_unregister'

hi,

 

Thanks for taking a look. I tried your suggestion but it has made no difference!

I have a similar problem with Session variables, I didn't look into it much so it would be nice if someone could come up with an answer for this one.

Just checking, shouldn't

if ($_SESSION['basket'][$key]['URN'] == $_GET['URN'])

 

be

 

if ($_SESSION['basket'][$key] == $_GET['URN'])

 

Are you entering the IF loop?  Echo out the array to make sure you are in fact getting to the unset command.

And Im not entirely sure how to echo an array to the screen...!?

 

Thanks for your help.

print_r($_SESSION['basket'][$key]) will echo the array contents, but you can see if it is getting there by just adding

 

unset($_SESSION['basket'][$key]);

echo "We ran the unset command";

Hi,

 

I commented out the

header("Location: StationaryMain.php");
exit();

part of my code so it didnt keep returning to that page and input that piece of code u gave me that would output a message but no message appeared, so i take it it isn't getting to the if statement!

Hi Ive changed the code so now it empties the whole basket but not the products individually...

 

<?php
session_start();
foreach($_SESSION['basket'] as $key => $product) {
	if ($_SESSION['basket'][$key]['URN'] == $product['URN'])
	{
		unset($_SESSION['basket'][$key]);
	}
}
header("Location: StationaryMain.php");
exit();
?>

 

It does now get to the IF Statement though.
