shopping cart remove item - compare

I am using the webforcecart.com (http://webforcecart.com) shopping cart.

The items that I add to the cart can be the same item with different variables. For example, T-Shirt can come in blue, red, white. So, if buy a blue one and a red one, the cart will display them seperately (normal functionality of a shopping cart).

My problem is that when I am removing items from the cart, I am identifying them in the array by their ID... so when I remove one, it's actually removing all occurances of that ID (so both the blue and red one get removed, even though I only wanted to remove the red one). That's the basics, there are actually 6 different item options that come into play.

line1, line2, line3, line4, font_style, icon --- they are stored in an array called $iteminfo.

So, I need the cart to remove only the item where the product i tell it to remove matches those 6 options.

The current delete function is this:
function del_item($itemid){ // removes an item from cart
$ti = array();
$this->itemqtys[$itemid] = 0;
foreach($this->items as $item){
if($item != $itemid){
$ti[] = $item;
}
}
$this->items = $ti;
$this->_update_total();
} //end of del_item

All the product info is being stored in these arrays:
var $total = 0;
var $itemcount = 0;
var $items = array();
var $itemprices = array();
var $itemnames = array();
var $itemqtys = array();
var $iteminfo = array();

I'm trying to extend the functionality of webforcecart (http://webforcecart.com/). I think if I can figure out how to complete the delete function to work the way I need it, I can figure out the other functions for updating the cart.

Thanks for any input or help you can provide.

Hi - I am doing practically the same thing with clothes sizes, colours using the webforce class, did you find a solution in the end?

I'm half way there with it, passes an array with the colour, size to the $cart->add_item function fine, just need to work out the best way to show multiple products which come from the same product_id they just have different selected attributes such as Colour, Size etc..

Thanks in advance any help would be appreicated

To be honest the class is very outdated now. You should consider creating your own class based upon the wfcart class

It is an old one, I was hoping somebody else might have already done this already :-)

Oh well, looks like I will just have to do like you say and rewrite this from scratch based on the original wfcart code - wish me luck :P

Thanks anyway :-)

Other than add, remove and edit methods, I don't really see what you would need tbh. I'd start the whole thing from scratch again

I'm just gonna use wfCart as a guide, rather than write the 'new' cart based on that, touch wood it goes well either way it will be a new learning experience for me :D

Yup. Any difficulties you can always post back :)

Cheers will do! Nice Pagination Class by they way! I could see myself using that in the future soon too! :)

Thanks. I don't even paginate results all that often, but when I do it takes 2 mins :)

Shopping cart - all done! Your comments inspired me to rewrite it and it does the job now.. will make a mini tutorial for this at some point for others to use/learn from.

Had another look at the pagination script - looks really good! Might try to implement this into one of my personal projects :)
