buy now button with quantity box

condoug

hi all

I am looking to find a solution to my problem.

A list of product info is built dynamically on my page and each product displayed needs to have a quantity text box and a buy now button. What I need is to understand how if a user types a quantity and presses the Buy Now button, how do I capture only that product/quantity posted and not the others on the page?

I have a structure to store my basket contents in a PHP session as such:

$_SESSION['cart'][$_POST['productid']] = array(	'productid' 	=> $productid,
														'quantity' 		=> $_POST['quantitytext'], 
														'productprice' 	=> $price
													);

Can anyone provide some advice on how I achieve this?

Many Thanks

You could put each one in its own form.

ahh interesting!

So the form name would be unique to the product i.e:

formname_1, formname_2 (where 1 and 2 is the product id) and then the buy now button's action would be:

onclick="document.formname_1.submit()"

Is this the correct approach would you say?

It will work for most people, but it requires the users to have javascript for no reason.

<form action="" method="">
	Quantity <input type="text" name="1" value=""/>
	<input type="submit" name="whatever" value="Buy product 1 now"/>
</form>
<form action="" method="">
	Quantity <input type="text" name="2" value=""/>
	<input type="submit" name="whatever" value="Buy product 2 now"/>
</form>

You don't have to name the form. The names 1 and 2 are product ids. Their respective values are the quantities.
