Module development and code questions

i've been trying to get the task.module working on my site and it is still giving me the error:

Fatal error: Call to undefined function: drupal_ucfirst() in /.../modules/task/task.module on line 1082

i've read the project notes and the suggestion about using the cvs release of the drupal head, but either it's not working for me or i misunderstood the fix because that is closing down drupal all together for me. any suggestions for what i can do to get this module running, or are there any other modules for tasks/todo lists or productivity in general?

Does anyone have any code written to display how many items a user has in their shopping cart, and if it's greater than none, to display the total (without displaying a complete inventory)? I know there's a function in cart.module for this--get_cart_items I think? But it might require the inventory listing.. anyone know?

Hi everyone,

I'm just trying to install the paypal module on mysql 5 and have run into a few errors when running the database script, and I was just wondering if anyone has managed to get it working to save me some effort :)

Many thanks in advance,

(PS - I've done a search of the forums but didn't find anything)

I want to have ~6 buttons in the same form, each w/ different operation. When user clicks "save" I want the function [form name]_submit() to save. When he clicks "run" I want it to save then go to another piece of code. Trouble is, I cannot get my function [form name]_submit() to pick up the value of the button that was clicked.

Hi there. I'm currently working a bit on a project where we would need a more powerful "comments engine" than the standard one provided by drupal. (Much because of that we needed a more powerful forum, and wanted the forum users to be able to comment articles). The idea was trying to implement punBB for this purpose (www.punbb.org). A bit tricky since punbb has has it's own authentication and we don't whant to mess around with that do we? ;) This is not the main issue though. First I tought it would be quite easy, just replacing the original comments module with a punbb powered one. But when I started to look at the comment.module code, I began to feel very confused. No big surprise there, I've started out just yesturday and I'm therefore quite new to how Drupal works. But after reading though some more guides I just felt I needed to ask someone about this, or it would take ages to figure out. ;) I'll just fire away then.

Some of the first questions that spring to my mind:

This comments module, could you look at it as a kind of interface module witch all other modules use for commenting functionallity?

If so, what hooks/functions would I need to implement in a punbb version for it to work with other modules? All of them? Just some "output" function?

Do I even need to owerwrite the comment.module or is there another way of setting the "comment engine" for a module?

I downloaded the Webserver Authentication module because it's very similar to the module that I need to write for my own site. It's a simple module, but I can't get it to work and I've hit a brick wall. Nothing works - Drupal doesn't recognize when I'm logged into my other authentication system, let alone create Drupal registrations on the fly. It doesn't even appear that the hook_auth module is being called, but I can't trace through the execution because Drupal doesn't use output buffers so inserting echo statements causes errors.

I have tested my login and authentication functions in a separate test program, so I know that they work. I don't know why my module doesn't work. It's probably something simple, but there is virtually no documentation on authentication modules, and I can't figure it out for myself because I can't trace through execution with echo statements. I need information on these basic questions:

- Which hook functions are called when (and not just from within the Drupal code, but from what user action)? I thought that hook_auth() might be called when the user logged in (that was a wild guess), but I can't get Drupal to call this function no matter what I do.

- Exactly how the returns of each function are used - in what other parts of Drupal. Without knowing this, I don't know what's required. In particular for hook_auth, but also for hook_info. When/how are the hook_info functions used? By what part of Drupal? What might call these, and why?
