I am using an open-source shopping cart that uses class objects for the cart functionality. I need to customize the object to add more information to the item selected.

My question isnt really about changing the class object (at least I hope I can go through the code to make the changes) but about generating the additional data.

on my product details page I have an anchor tag that will pass the product id. Also on the page I have inputed information about personalizing the product.

What I need is help taking the inputed information and adding it to an array variable that will be passed with the product_id when the anchor tag is clicked.

<a href="add_cart.php?id=<?=$prod->id?>?personalize=(the array variable)>.....

Is there away to create the array possibly in a function that is called when the anchor tag is clicked. Also do arrays accept null values? If I write a conditional statement will this work to handle null values.

if(!$variable == null){
array[]=$variable;
}

thx in advance,

Alex

I would imagine to transmit an array over query string, you would wish to serialize it first.

But I don't reccommend doing so.

Also, It's ? to begin the query string & to go to the next element.

Does this answer your question -- I don't believe I understand your dilemma.

my bad on the ? and & in the anchor tag.

well my dilema is what type of coding can I use to create the array when the anchor tag is clicked. I guess I could create a button the create the array first then pass it but I wanted to minimize steps.

and could you elaborate on passing an array value in a query string. Is this not possible?

Thx
