Module development and code questions

Hi,
I'm new to drupal and startet writing my own modules. Now that I have tried the upcoming 5.0 version of drupal I want to continue developing my modules for the new version.

I created a new node type and extended the node form by using the hook_form(). According to http://drupal.org/node/64279 (Converting 4.7.x modules to 5.x) this hook does not seem to have been changed or removed so I thought at least displaying the nodes form should work. But it seems I'm wrong.

Within a module I have hook_settings()... where the form and its values are defined...

Is their any hook I can call when a user changes values on the settings form?

When a user has changed a value I need to call some functionality of another module...

I have built a simple form which seems to be capturing the data ok as I have checked the database that they are inserted correctly. When I tried to edit the form, the form displays default values for each field instead of the data from the database, what could be wrong?

When you have something like

function hook_insert($node) {
  db_query("INSERT INTO {mytable} (nid, extra)
    VALUES (%d, '%s')", $node->nid, $node->extra);
} 

Does %d mean number or integer and %s mean string? are there any others? Is there a page in the handbook that explain this?

Hi,

For a school project I have to adjust the chatbox module. Now I'm trying to make a form, but it won't work and I don't know what the problem is. I'm new using Drupal and I've read the handbooks and I've also read the Forms API Quickstart Guide, but I still don't understand what I'm doing wrong. Here's what I have so far:

Hi all,

I have just tried the PhpGedView module. I have been using PhpGedView for some time and thought I would have a go at integrating it with Drupal. I have a test system setup with the latest Drupal and PhpGedView. I have followed the installation instructions for the module (I am a little hazy on what exactly step 3 of PHPGEDVIEW SETUP refers to).

The module is installed and I can see the Family Tree page. However, when I log into Drupal, it dosnt also log me into PhpGedView. I also can no longer log directly into PhpGedView.
