Module development and code questions

I'm modifying block.module to allow Drupal to display blocks based upon the role a user is assigned. I have this code:

  $rroles="SELECT name FROM role";
  $rrroles = db_fetch_array(db_query($rroles));
  
	   foreach ($rrroles as $reles => $names) {
		    $options = array();
		    $options[] = t($names);
	    }

But it only returns one result. I've tried a while loop but the page hangs. All help would be deeply appreciated.

I installed wordfilter and added some of the standard words. I am assuming wordfilter works, but I was a bit taken aback when I notced that the offending words are listed on the compose tips page.

How do I take them off of there?

Hi

I have a problem with a table over-lapping the side block.
http://urbits.com/_test/table_over.gif

So far, when I've needed to customise a page, it's been adding something in - that's going ok. But in this case I assume I need to understand is how blocks are suppressed on an adhoc basis. Is there an unhook_block() function (does that show my newbiness?)

I'm going to do this, comments are welcome. I also have a quotation module proposal on its way.

External Quotation Module for Drupal Ecommerce Package

Goal

- Ease the purchase for large organizations like a university;

Features/rules

- In the normal cart, a registered user can generate an external quote instead of a real purchase, and external quote terms are displayed;
- An external quote can be purchased without need for user registration; FIXME: any security problem? What does the law say?
- In the order status/tracking page, user can: enquiry external quote status, remove an external quote if not being purchased and not expired;
- External quote is kept in the order status/tracking page as the way a normal order does;
- External quote is valid for a limited time (as it holds the stock) either specified by the administrator or any shorter product/service expire date.
- The status of the external quote is emailed to its requester automatically, including a purchase reminder several days before expire;
- External quote is identified by a unique number which is separated enough or coded to proof typo and malicious probing;
- Requester information is filled out by default at the check out page

How
- A database table for the external quotes with the fields: external quote number, internal order number, expire date, status; FIXME: I guess there should be an order table from the ecommerce module for normal order information including the buyer information???

Hi-

I'm working on an action to send an email to everyone in a role group (e.g. "Send an email to editors when new content is in the draft state").

I need to set up a check box of roles. Here is the code:

$roles = user_roles();
$form['recipients'] = array(
        '#type' => 'checkboxes', 
        '#title' => t('Recipient Role Groups'), 
        '#options' => $roles,
        '#description' => t('Select which roles should receive this email.'),
    );

The creates an #options field with the form:

array( rid1 => 'role name 1', rid2 => 'role name 2' ...)

This works well at first, and I can properly save the form, but if I return to the edit screen later, the form isn't properly populated because I have an $edit array that looks like:

[recipients] => Array ( [3] => 3 [1] => 0 [2] => 0 [4] => 0 [5] => 0 [6] => 0 )

All the other fields (subject, message body, etc) are nicely filled in. I suspect this is because the options I supply in the code, don't match the options in the $edit array.

Any thoughts on how I can get these to mesh?

Thanks

Hi. I've been reading about the hook_filter and the ability to cache data. I noticed that in the database, the raw, unfiltered text is stored. I'm assuming the filter fires each time the node loads, unless the filtered text is in the cache. I have caching enabled in settings, but I understand that caching really only applies to anonymous users. Does filter caching work the same way? Is there a way to check to see if the logged in users are getting the cached versions of the filter output? I want my logged in users to get the cached versions since it is much faster. Thanks.
