Prevent adding product to cart based on date comparison

I'm building a conference web site and as part of the site, we offer various paid courses that are happening simultaneously and I don't want the user to be able to add an event (product) to their cart if they already have added a product to the cart that's occurring at the same time. I've created a start date field for which to compare this information but problem is I'm not sure of the best way to build this functionality. I'd like to disable the add to cart button using the Calculate Sell Price event.

Any advice is greatly appreciated.

Adding product image field to view


I'm using Drupal 7.28 along with the Commerce 7.x-1.9 module

Basically the image and the description fields are both on the Product Type not the content type as each product has its own description and image.

In my view I now need to add the image field, but I can't add it, which I believe is because the field isn't in the content type.

When I add the 'Content: Referenced Products' relationship to the view, I am then able to add the image field to my view.

Commerce Australia Post

Can anyone please explain more about Commerce Australia Post? It is still confusing for me when setting a 'Default Maximum Package Size'. How will I set it up correctly? How does this 'Default Maximum Package Size' works? What if the product size exceeded to the default maximum size? I tried to calculate the item manually using their website (, the result of shipping fee from my website and the result from their website is different. I need help please....
Many thanks.......

Product variations all have same title?

I'm using Kickstart 2 and have created some variation types. I've added a product with four different variations. When I create each new variation under the variation's 'Variation title' it says 'Will be auto-generated when the form is saved.'

Then when I go to the product display, under the variations drop down all of the variations have the same name, see the screenshot below:

Donation and a Custom Price when Adding to Cart

I have watched rfay's screencast on creating a donation form with custom line items. I have actually created it on the current version of our site. It works wonderfully, however, in the new version of the site the form is a lot more advanced. Because of this I created a custom module to build the form (you can see it here:

My question: is it possible to get this custom form's "donation" field to play nice with the rule I've already set up from the screen cast?

About Taxonomy and Drupal Commerce

Hello Drupal Commerce community.
I'm starting to build a new Drupal website, this time with Drupal Commerce.
I've made the structure for the products on a word document.The website will have a Superfish mega menu with the categories, but now I'm not sure what should I create first.
Should I first create taxonomy vocabulary, the products and then the mega menu with url taxonomy terms?
I will be really grateful if someone explain me the right order.
