Re: Delete from cart

Thanks Chris, It is a little late in the design to use your class, but it has given me an idea on how to delete from my code. Thanks Gary Chris Lee wrote:

here is a very simple cart in sessions. you have stockno and quan, it can be easily modified to handle various other variables. <?php class cart { function add($product_id, $product_quan = 1) { if ($product_quan < 1)

$this->cart_product_id[$product_id] = $product_id; $this->cart_product_quan[$product_id] = $product_quan; } function add_single($var_name) { if ( !isset($GLOBALS[$var_name]) )

    return ;

$this->add($GLOBALS[$var_name], 1); } function add_multiple($var_name) { if ( !isset($GLOBALS[$var_name]) )

    return ;

foreach($GLOBALS[$var_name] as $pos => $val)

    $this->add($pos, $quan);

are you using a spec cart system? or did you write your own? its hard to give an accurate answer without knowing. Ive wrote my own simple cart,

using

sessions, to delete an item I just unset the variable. unset($stockno['1234']); where $stockno is an session array variable. its very spec on what

software

your using. -- Chris Lee Mediawaveonline.com em. lee@mediawaveonline.com ph. 250.377.1095 ph. 250.376.2690 fx. 250.554.1120 "Gary" <deadfred@2sie4.com> wrote in message news:3A8D8B39.4020208@2sie4.com...

Hi All, It is Friday afternoon here and I don't want to have to reinvent the wheel. What would be the easiest way to delete an item from a shopping cart? I know what is required for Mysql but I am stumped on how to implement it.

I am writing my own system. It is using cookies to give a temp id number. When you choose something from the menu it uses the stock number to generate a description and cart page. I was thinking about using the stock number with a db query to delete the row. I am not sure about the best way to accomplish this.
