Like a lot of other people here, I was looking for a way to show attributes on the product listing page, so when I found this mod, I did a little happy dance. Unfortunately, there appears to be a major problem with it.
By using certain settings in ADMIN>CONFIGURATION>PRODUCT LISTING (see below), I set the site up so that an Add to Cart button shows for every item on the Product Listing page, whether the items have attributes or not. This is where the problem comes in. When clicking on one of those Add to Cart buttons, the attributes do not show up in the shopping cart, regardless of whether or not the attributes change the product price. If I go to the Product Info/More Info page and click that Add to Cart button, everything is fine. The attributes show up in the cart as they should.
Now, if I change the admin settings so that instead of cart buttons appearing for every product, there are Add Selected Products to Cart buttons that appear at the top and/or bottom of the Product Listing page, then it works. Clicking on that button will add the attributes to the cart. But I don't want that since it requires that a shopper add a product by entering how many they want in the quantity box and then scroll up or down the page to find the add button.
I suppose it's possible that I need to make some other changes in my admin settings to get this to work or that there's something else interfering with it, but I don't know what it could be. Is there anyone out there who is successfully using this mod in the way that I want to use it?
For your reference, the settings I used in ADMIN>CONFIGURATION>PRODUCT LISTING to get an Add to Cart button for each product are as follows:
Display Product Add to Cart Button (0=off; 1=on; 2=on with Qty Box per Product): 2
Display Multiple Products Qty Box Status and Set Button Location: 0 (This turns on or off the Add Selected Products to Cart button that appears at the top and/or bottom of the Product Listing page, which, when on, disables individual Add to Cart buttons.)
Here’s the URL to the site. It's just a test site that I'm working on to see if I can get Zen Cart to look and work the way my client wants it to.
