Module development and code questions

Hello all,

What's the best way to check if a user has ever logged in?

Thanks, A.

I am trying to extend the E-Commerce module to include a 'quotation' cart feature. The quotation cart module will show the products without any prices, instead, the customer makes a list of he desired products (together with the required quantity etc) and submits it to the shop owner as a quotation request. The shop owner will receive the quotation with input spaces to enter the prices and by submitting the quotation it will be emailed to the customer as a pdf file.

Here is a question for the E-Commerce module developers:

When I click the modules link on the administration menu...
Drupal can't show me the modules list under the URL http://www.mysite/?q=admin/modules

Many/most who use event.module desire the ability to generate a page or block of events (sorted by date) which have been tagged with a particular taxonomy term. Event.module does not seem to offer this capability.

I would think views.module could achieve this. Could anybody post example code as to how this is done, or an alternative approach?

Thanks

Hi

On my site there is a place where Idon't want that the nodes have Author/date/taxonomy/link... Only title and Body. I modified the theme, but in this will affect the news menu too(where is a need for uthor/date/taxonomy/link... )

How would you solve this?
