Products with multiple Attributes

It's just showing up because you have multiple products on the form that share the same attribute field values. It lets you drill down a single product from that set of matching products to add to the cart. It doesn't show up for other combinations because there's only one matching product.

So there's only one option in the "Select a product" list?

It's just showing up because you have multiple products on the form that share the same attribute field values

I am facing same problem when product(variation) having the same attribute , which could/should be avoided by admins but for the commerce module why would it treat it as same product when they have unique SKU.

Is there anything that has to be done, to avoid duplicate products by applying unique field on product title or some other field?

Same problem on a fresh installation. It seems to happen only when using multiple attributes based on term reference fields.

Here is my use case :
- product 1 : Size=L / Material=wood
- product 2 : Size=L / Material=metal
- product 3 : Size=XL / Material=

When the display product page load, I have 2 select inputs (Size / Material) = OK
If I select Size=XL --> I have just one select input (Size) and the price is updated = OK
If I select Size=L --> I get 3 select inputs (Size / Material / Select a product) = KO

In the "Select a product" list there is 2 options :
- product 1 (L, wood)
- product 2 (L, metal)

If I select Material=metal (default is wood) --> "Select a product" disappear

Hope this description can help

Same here
Edit: It hapens only if you same sku's

Having the same problem. Both "size" and product select selects get rendered. This is happening on AJAX call only, when page is loaded by default it does not. Also when I use select and ajax refreshes this "select a product" goes away.

Here is html I get on Ajax call.

<div class="form-item form-type-select form-item-attributes-field-size">
  <label for="edit-attributes-field-size">Size </label>
 <select id="edit-attributes-field-size" name="attributes[field_size]" class="form-select ajax-processed"><option value="15ml" selected="selected">15ml</option><option value="30ml">30ml</option></select>
</div>
<div class="form-item form-type-select form-item-attributes-product-select">
  <label for="edit-attributes-product-select">Select a product </label>
 <select id="edit-attributes-product-select" name="attributes[product_select]" class="form-select ajax-processed"><option value="1090" selected="selected">LUNA™ LUXE 333</option><option value="1091">Rreee Luna Lux</option></select>
</div>

Correct Cedric_a, I can confirm your case as well though mine with 3 attributes.

1: size: L, color: Black, Clip-material: plastic
2: size: L, color: Gray, Clip-material: metal
3: size: XL, Color: Black, Clip-material: NULL/Blank (as product 3 doesn't have a clip)

Starts on product 1 so attributes are on Size: L, Color: Black, Clip-Material: Plastic

If you select Gray you get product 2.

Then you select XL, Color auto chooses black, and Clip-material disappears, you get product 3.

Then select L and you get the "Select a Product" attribute at this point and it stays on Product 3. This is a problem as by selecting Large since the color was still selected as "Black" I should have gotten product 1 but I did not.

This is caused (from what I see at least) from selecting a product field as an attribute that is not a required field and therefore will be blank in some cases. When you select the attributes to pick that product with a "blank" attribute, when you try to go to any other product that has that attribute filled in you automatically get the "select a product" attribute.

I don't know if this was by design (and if so I think you should not allow us to select the field as an attribute if it isn't a required field) but my work around was to give product 3 a Clip-Material of "No Clip". Now it all works fine.

Hey all,

OMG this was an infuriating issue for me, and the kind of things DC continually throws at you whenever you want to create slightly more complex setups.

In my case however it was easily solved in the end with a hook form alter. I initially thought about unsetting the form element completely, but decided to leave it there just in case but change it from select to hidden as follows.

function MY_MODULE_form_commerce_cart_add_to_cart_form_alter(&$form, &$form_state, $form_id) {
//    dpm($form);
//    dpm($form_state);

    if(isset($form['attributes']['product_select'])){
        $form['attributes']['product_select']['#type'] = 'hidden';
    }
}
