Dear All,
Please give me your wish list for ecommerce. Next week I'll be at the drupal conference. I'll try to talk to developers after enhancing the module, to include automatic debiting for paid memberships and to manage more than one role. see node 47263. I've spent a lot of time trying to get paypal subscription to work. see node 44295 but I just installed ecommerce yesterday.

My fellow drupal developers,

I am planning to extend a module to include aditional functionalities. I am pondering between inserting this new functionality either in a extra php file which the module includes, or to add new hooks to the module that then calls the implementing module.

I am aware the second option seems the most desirable, but how much overhead does the hook system adds, if the hook is made in a place where multiple call to it can be made per page request (up to 20 requests)?

Could someone give me an advice on the best approach?

I'm creating a module that needs to know the uid of a new user to update a db table. I've tried placing my SQL call in the 'validate' and 'insert' sections of hook_user, but neither work: in validate I get a uid of 0, in insert I don't get a uid at all.

Any help on this? The life-cycle documentation for many of the hooks with operation arguments is pretty poorly documented. I'm not even sure that $user or $edit is valid in a hook_user 'insert'.

Thanks

Does anyone have php code to build a CSS ID selector from a simple node url?

it would convert a node in the form

"node/subnode/subsubnode/subsubsubnode"

into:

"node-subnode-subsubnode-subsubsubnode"

So that the resultant string could be inserted into the output html with a css ID selector on every node drupal displays.

This function would go into the

node.tpl.php file of a phptemplate theme

So that certain desired nodes in pages produced by the theme could be styled in the style.css with the node unique ID selectors:

Ecommerce and Generic modules

I have installed Ecommerce and Generic Module.

I would like the Generic module to automatically grant roles to users who pay through PayPal.

All comments greatly appreciated.
