hi, i'm working on a shopping cart. i store the necesary field in session and pass it to user cart when user add the item to cart.

this is how i store my session:

<?php
if (isset($HTTP_POST_VARS['pid']['pid'])) 
    {
        if (is_array($_SESSION['pid']))
        {
            if (!in_array($HTTP_POST_VARS['pid']['pid'], $_SESSION['pid']))
            {
                                $_SESSION['pid'][] = $HTTP_POST_VARS['pid']['pid'];
            }    
        }else
        {
                        $_SESSION['pid'][] = $HTTP_POST_VARS['pid']['pid'];
        }
    }
?>

this is the checkbox:

<?php
print \"<td width=5
?>

\n\";

and this, when user check the checkbox and click delete:

<?php
for ($i=0; $i<count($cb); $i++) 
        { 
            unset( $_SESSION['pid'][$cb[$i]] ); 
        }
?>

if i hv 2 or more records in my cart, when i check the first item to be deleted, it will delete all of them. anything wrong with my code?

pls !

i got this error:

Quote:
Warning: Invalid argument supplied for foreach() in c:\inetpub\wwwroot\kbj\shop_cart\user_cart.php on line 144

and line 144 is :

<?php
foreach ($cb as $i) {
?>

joyce, how about I sponsor you with a little space/bandwidth on a real Linux server for development's sake? Email me..

Cheers..

hi zollet,

i normally worked on localhost first b4 i upload it to the server.

this is the session file(when i add 2 records into the cart):

Quote:
pid|a:2:{i:0;s:1:"4";i:1;s:1:"1";}

and this is the session file when i choose one of the record to delete:

Quote:
pid|a:1:{i:1;s:1:"1";}

but on my page, when choose one record to be deleted, it deletes all the records. so it shows an empty cart at my page.
i just dono why...

If the foreach is failing, then $cb is not an array.

I have 2 debug ideas...
1-inclose the cb[] in quotes
2-print $cb

<?php
// 1
print \"<td width=5
?>

\n\";

// 2
print_r($cb);
