Module development and code questions

how to add a net money modules just like user point modules ?
1、 user can use his net money to buy product。
2、administrator can add user's net money after get user's real money.

so I only want htmlarea to work in a certain area on a certain module page so I definited it like this:

node/*/feature.edit-body

I get htmlarea in the textarea when I go through create content, but then later when I go back to edit it I don't get the htmlarea controls for that area

any idea how I can fix this? thanks!

I'm trying to create a new permission for the comments module. I know that I can add a new permission to the comment_perm() array and the new permission will show up in /admin/access. What I don't know how to do is then create all the supporting code to enable that permission. I want to be able to grant any user the ability to delete any comment they've left anywhere on the site. I'm really struggling to find out where/how/why you implement the new access permissions, or even where in Drupal's "documentation" to find any examples.

Any offerings greatly appreciated.

I have a couple textareas inside a collapsible fieldset, I set #collapsible = TRUE in the fieldset, but when I enable the htmlarea module the fieldset comes out un-collapsed, I mean like open all the way

any idea how I can fix this? thanks in advance!

I posted a job for this recently but I may end up doing this job myself because it doesn't appear to be as difficult as I thought it was.

Basically I want to combine the e-commerce package, directory module (in development), & custom node types to create a paid-subscription directory for searcy.com.

The user will submit a custom node type called business listing and then be redirected to a place where they buy a corresponding business listing subscription. The subscription is a non shippable product that uses monthly recurring billing.

I have a few textareas in a form, the first 2 get TinyMCE, but the rest don't

It's nothing to do with the textareas themselves, if I move them around it's still only the first 2 areas that have TinyMCE enabled

why is this? how can I fix it?

thanks in advance!
