[SOLVED] Shopping Cart - Update Form Logic?

[AbydosGater]

Hi, im currently working on a small shopping cart script.

 

I cant seem to work out the logic for a form that will allow the users to edit their cart items.

I have a form that loops through all of the items they have added to their cart and shows them with a quantity textbox for the user to change selected quantity.

 

The thing is, the user could have any amount of items listed, and each form item is named "quantity".

So when the form is submitted i only get one $_POST['quantity']; for whatever the last product in the form is.

 

I was wondering if someone could help me with the logic behind displaying a unknown number of form elements and then looping through them for processing?

use an array like

 

<input type="text" name="quantity[MAYBE_THE_ITEM_ID_HERE]" value="10" />

 

Then in your php you can access like this:

 

foreach ( $_POST['quantity'] as $key => $val ) {

    // $key in this example would be the Item ID and $val would be the new quantity

}

Works Perfectly.

 

Thanks
