Module development and code questions

I have read the documentation of the menu system on the Drupal API website, but I can't quite figure out how to use it for my module. I think I am missing something basic, and I hope someone out there can help.

What I want to do:
My module ('foo') sets a session variable but does not create any content to output. When a user visits foo/node/1 the foo module should be called. It will set a session variable, and then the content of node/1 will be displayed as normal.

I built a site that uses the RSVP module. The person I built it for first emails everyone about a meeting and they usually get back to her about whether they will attend the meeting or not. Unfortunately, these people don't login to the wonderful drupal site I made ( ;) ) and RSVP for the meeting. What I want to be able to do is make it so the admin can manually set the RSVP for the members.

Is this possible?

Hi all,

I've seen a site which is using EventFinder module and I decided to add the module to my site.
The problem is after installing EventFinder, the eventfinder page is white, so is the setting page.

I've already had the event module and location module installed and activated.

Can you help me?
Thanks.

Drupal 4.7.4, EventFinder 4.6.0

Hi everyone,

Im banging my head a bit...

How do I get all nodes of a specific type? I dont want links, I want the actuall nodes as arrays or objects, along with all the respective data for each node.

In my little head I am thinking of something along the lines of a magic API call like:

$nodes[ 'someTypeHere' ] = get_all_nodes( 'someTypeHere' );  

Where this magic "get" function would return every node as an object or array for the passed "type"...

I am trying to find a way to use a (table) view (generated with CCK and the views module) and click on one of the rows to open an edit window to be able to edit the row's content. Is there an (easy) way to do that?

The question may be stupid, however, I have just started to get acquainted to Drupal.

I am grateful for any suggestion.

Thanks in advance,

Knut (flupphugat@web.de)
