Module development and code questions

Hi there,

I am trying to fit the jsDOMenu module into a drupal package so that it becomes easy for people to create their own menu. After installing and setting the module, I realised that there is no none-coding way to actually create the menus, because the Java Scripts must be initialized in the HTML page.

The url_alias has a field called 'pid' which I assume stands for Path ID. Is it actually referenced/used anywhere else?

The reason I am asking this question is I have certain rows in my url_alias table in which the src is the same and the dst is different. This was caused due to me repeatedly fiddling with the pattern setting of pathauto and then bulk updating (with the retain old aliases enabled).

I want to delete the older aliases. I am not really concerned about breaking old links or aliases from outside. However I do not want to break anything from inside Drupal.

Is it possible to define callbacks for a specific module that can be used by other modules to modify module behaviour.

Specfically, I want to add some callbacks for the project module for creating and deleting modules. I then want to hock into these callbacks in another module (project_svn) to add/delete folders in a subversion repository.

Is this possible?

TIA

I have the following query that works perfectly in phpMyAdmin, but Drupal reports an error at the top of the page. What's weird is the resulting recordset data actually displays correctly within the page, yet Drupal complains nevertheless. Is there a way to satisfy Drupal or suppress the error? I have wasted two hours trying to make Drupal happy and rechecking (and rechecking and rechecking) my syntax. Needless to say this is freakin' annoying.

this gremlin likes to claim nodes, and he won't let you post any attachments to them.

he seems to thrive in environments that include filemanager/attachment modules, though i haven't tried to incubate him in a different setting.

in my case, he likes nodes 12,13,14,16, but he doesn't like nodes 11,15,18

i've studied these nodes in the DB and can't find any sort of patterns. nodes might have single or multiple attachments already (before the gremlin reared his head. they might have no common properties in the database.

Sorry for the bad english. I'm modifing video module. I've inserted a hook_view called video_view() in the code to show an image in the node. But the image is showed only in the node details, not in the preview (in the home page). How can i can show that image added at $node->body also in home page, where nodes are listed? I'm using slash theme in Drupal 4.6.2.
