Module development and code questions

Just looking for some feedback about the best way to approach this problem.

I am using the image.module to keep groups of photos together. In essence (if my understanding of Drupal is correct) this attaches a specific taxonomy (admin defined) to all nodes of type image. Then a specific term from that list is chosen for each photo. In my case, the terms are the names of the "album" that the picture belongs to. What I am trying to tackle is this:

hello,

I'm trying to develop a module, but I can't get any value back from the form.
The following doesn't work:

$myvar = $_POST['myvar'];

Does Drupal somehow nix he $_POST array? How should I access the posted vars?

Thanks.

Hello, I'm developing a Drupal 4.6.2 based site for an educational organization, we will have students and teachers from universities in several countries.

I know how to create new node types and for this project I will create a couple of "base" node types (university and country) that should be used by other node types, so the administrator can add new universities and countries as needed.

Hello,

For some nodes in my module, I'd like to add some data in the headers, like additional META tags, or some extra css styles.

I can't find a hook_html_head() function that would allow me to do so?

Can you confirm it's impossible, or is there a way I missed?

thanks.

Hello ,

I am having difficulties installing the patch taxonomy_all.patch on top of drupal 4.6.1
with both normal and enhanced privileges.

The patch has been uploaded to the root of my drupal installation.

From this directory when i issue the shell command
# patch < taxonomy_all.patch
File to patch : database/database.mysql

i receive the error
... can't find file to patch at input line 28

Similar problems are found for other patches for database/updates.inc and modules/taxonomy.module

I'm brand new to Drupal, after about 4 years of PostNuke.

One of the features that is super cool in Drupal, and one I would have written for my PostNuke sites if I were not making the switch is the drop down menus, and just to be sure we're on the same page, I mean the menu options you click on that then roll down more directly underneath.

I'm going through the docs now. I've been through modules developer guide, but maybe I missed how you make one module a 'sub-module' of another.

Can anyone point me in the right direction?

Thanks!
