Module development and code questions

How can we create multiple nodes using a single module?

It is urgent.
Thank in advance.

Hi

I am using 4.7-beta3 and I want to add some data to $user as its database intensive but changes very slowly so I don't want to recalculate it every time the block renders.

I added to my_user() the following:

I just installed the og.module. I created a group when logged in as admin and made a few posts to the group as admin.

When I go view the group as another user, I can't see any of the posts in the group even though I added them as public posts.

The group just says "No posts in this group.", which is not right because I just created a post in that group.

Even when I subscribe to the group as a different user, it still says "No posts in this group.".

I wanting to insert a banner on the top of a story, like where the title is..

Lets say I have 2 topic lists

Topic List 1
Banner 1
Banner 2 *
Banner 3

Topic List 2
Topic1
Topic2 *
Topic3
Topic4 *
Topic5

So lets say I select the one with the *'s

I want to hard code this to use the one in topic one as the banner, so I will code
<img src="http://www.pathtothebanner.com/<? php print $WHAT FOR JUST THE TOP TERM ?>"

Hello,

I writing a module to allow Drupal to interact with an ASP I use for advocacy campaigns (where individuals send emails to elected officials). The ASP authenticates users via an HTTP POST and returns a cookie, allowing users to browse to any advocacy page and have the fields prepopulated (name, address, etc).

What I want to know is this.

Which hooks are called by module name and which are called by node name?

By which I mean, if I define multiple node types within a module using hook_node_info(), e.g

function theatre_node_info() {
  return array('show' => array('name' => t('show'), 'base' => 'show'),
    'venue' => array('name' => t('venue'), 'base' => 'venue'));
}

but the module is called theatre.module.
