Module development and code questions

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.

Node discussion: 46724 assigning users to roles programmatically

All comments greatly appreciated.

I'm trying to use the field select that comes with the contrib folder in flexinode.

I'm trying to edit my own node-flexinode-x.tpl.php, and I'm trying to fetch all sorts of fields, using $node->flexinode_y (where y is the field ID).
For the most part it works fine. But with the select field, I only get the option number, and not the text.

For example, say I defined a select field (lets say, with field ID 7) with the options:
OptionOne
OptionTwo
OptionThree
OptionFour

I'm looking for module that make possible vote on users profiles. Is there anyting like that? Thanx for answers.
