Chad,

thanks for your response.

Any suggestions on how to hide the 'add to cart' button for the special product class?

I can think of:

1. hack it where the button shows up (bad choice)
2. some sort of theming hook (I don't know where, some pointers would be appreciated)
3. through some existing ubercart or Drupal features that I don't know

What I want is a page like:

x prod1 attr1 attr2 ... price1
x prod2 attr2 attr2 ... price2
...
x prodn attrn attrn ... pricen

'add to cart'
(x stands for check box)
user can select multiple check boxes, hit 'add to cart' once.

I think Chad is right that custom form is the way to go for this page, please let me know if otherwise.

In addition, I'd like user NOT to see 'add to cart' button, if he browses the individual product. Essentially, force user only to use this page to purchase these products.

Thanks for your response. Thanks for providing so many pointers.

You mentioned "a loop that finds all flagged products", which requires some query to build a product list first.

Are you aware of some drupal function can do the 'query' (or search) for products (nodes)? node_search() don't look like it.

I hate to use sql query to search the node table in db directly, if I happen to bypass any existing drupal functions, it may make the module less portable. However, if db query is THE way to go, I'll do it.

I generated the form the hard way using forms api. Inside my_form() function I used brutal sql select to retrieve the nodes, filled in all form variables.

I didn't see where I can use hook_form_alter() function. I suspect I didn't do it right.

In my case, I have a new content type, added new cck fields. Then I added a table view with these fields. It looks something like:

col1 col2 col3
*************
V11 V12 V13
V21 V22 V23
...
Vn1 Vn2 Vn3

The form basically looks identical as the view, except one more column of check boxes and a submit button. It should look like

id col1 col2 col3
****************
x V11 V12 V13
x V21 V22 V23
...
x Vn1 Vn2 Vn3
"submit button"

where 'x' stands for a check box.

I felt like there got be a better way to take advantage of the view , which already contains all the contents for the form, except the check boxes and a submit button. I am playing with theme_views_view_table(), so far, it has not got me anywhere.

I've run into the same requirement for our site. Do you have any snippets from your solution available?

Thanks,

Have you had a look at the product kit Contrib?

Hmmm, maybe you could use workflow-ng for this? The user could put courses in the cart along with other products. Then at checkout create a workflow that takes the user through whatever process they need to go through for registration if the cart contains any products that are in the product class "course".

I built an e-commerce platform (not ubercart) for a client that does class registrations. They have courses for registration and shippable products from the school store. I treated the course itself as a type of product that is simply added to the cart. Upon checkout, if course products are in the cart, the user has to register an account or login. Then it goes through a verification process (is the class full, is the user banned from registration, has the user already taken the course, has the user taken the required prerequisite courses, etc). Then the user has to fill out registration information which gets saved as part of the user record. After payment, the course is added to the user record. Basically, everything is associated with the user record. The user's role is "student".

In Drupal, you could use profile to store extra information in the user record.

Hope that helps.

I'm wondering if this is the kind of thing you are looking for but instead of textfield's you would want checkboxes. http://www.itiswritten.com/give/donate
