Module development and code questions

i followed the handbook instructions for making a module settings page (http://drupal.org/node/82967)

however, no directions are provided for validating module settings.

can anyone tell me the canonical method of validating module settings, or suggest a module that i can use as a model?

thanks!

So I'm letting people post their financial hardship stories on a site, and collect funds from other people towards their cause.

- A plea is a CCK node type: Plea. It has a description and an amount.
- A donation is a CCK type (with node reference to a Plea) containing amount and a 1 line description.

Basically I want to implement a tip jar for each Plea node (complete with progress bar and all). I will collect their money into my own Paypal account and then disburse it by hand.

I am trying to figure out how to fix an error I receive when installing the spreadshirt module. The error says:

Spreadshirt Shop
Error: Config (css_select)

I looked on the issues page for this module and a few other people are having the same problem but no resolution was given. I am very amateur programmer but would really want to start my own drupal/spreadshirt shop so all help is appreciated. :)

Hi all,

I have recently been putting together a site with drupal and I think it's great!

Anyway, i've come across a limitation with the nodwords module. I'm wanting to do good SEO, and as such have lots of good keyword, good content, incoming links etc, and a good description. This description however usually is best to be about 4 sentences, which exceeds the 255 characters allowed in the nodewords module.

The problem is obvious when you look at the source of your webpage (browser -> view source) -> characters exceeding the limit are chopped off.

I have enabled forum module (comment and taxonomy too).
It seem O.K. but when I tried to create a new topic ... there is nothing appeared in forum.
However, Topics are appear in content list. =_='

Did you see this problem before ?...

I want to have a large number of static large audio files for download, besides this I've been trying to find a decent solution to implement a streaming function of compressed file copies (wav | mp3)

I hope to save some time by asking for suggestions ie what module hacks should I go for. And perhaps get a few pointers to get me going.
