Module development and code questions

HI,

when i open the /blog/feed page in drupal, i get an error thats says :

this is the output from the opera browser. In IE it works fine but IE is ignoring the first empty lines.

I just wondered if anyone has any examples they want to share of using the excellent category.module?

I've obviously seen the tutorial on greenash, but wondered if anyone out there wants to share alternate navigation set-ups, or even their own tutorials. I'm just trying to get more of a feel for it and to see even further its potential.

I'm trying to get my head around the full process drupal uses regarding making nodes safe for display and whether there are any changes in 4.7 regarding this. I did a quick search and could not find this decision tree written out, so I thought I'd take a quick stab. Can anyone double-check that this sounds correct:

The process begins with node.module’s node_view making the following decision: If the node type’s module has a hook_view, let the module handle any filtering. Otherwise node.module will pass the body or teaser through node_prepare.

If we are using a hook_view, the module should first call node_prepare on the body / teaser. Then the module will pass it on to the theme. An example from forum.module’s forum_view:

$node = node_prepare($node, $teaser);
$node->body .= theme('forum_topic_navigation', $node);

This would suggest that the theme should not have to worry about making user-supplied content safe, but it appears that the general practice for custom content fields is to filter them in the theme function. On reason for this might be the l() function, which seems to filter the title of the link. If we were to filter all content at the hook_view level, things might get double-encoded[1]. However, in theory this opens the door for site admins and theme developers to overlook these calls to check_plain or l() while overwriting the theme function in their theme.

Webcomics is listed in the modules area but when I went to submit an issue for it webcomics was not listed in the projects dropdown list. That might explain why no requests, issues, etc have been submitted for the webcomics module yet :)

Not sure who can fix this but I think there will be others trying to help Eaton with the module soon and it'd be nice to be able to communicate here at drupal.org

hey, I need to design a web site for a commercial activity which wants to publicize their products online.
I'm currently trying to evaluate the ecommerce drupal module, in particular the products submodule.
What I need is to be able to categorize all products so that different products will be available on their category page.
Can I do this with the taxonomy module or do I need to design my own Database structure with product/category tables?
