Module development and code questions

[newbie]
I'm modifying the upload module to create/manage thumbnail images for our site. I'm really close. The single remaining issue (I think) relates to the javascript (upload.js) that is attached to the input form. In the module there is a path to "upload/js", which appears to be the location of the contents of the upload form, themed using the theme methods in the upload module.

However, it doesn't seem to exist on the disk. It's just in memory, I think.

I've got this taxonomy block error with version 4.6.6:

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ') AND n.status = 1 ORDER BY sticky DESC, created DESC LIMIT 5' a query: SELECT DISTINCT(n.nid), n.title, n.body FROM term_node t INNER JOIN node n ON t.nid = n.nid WHERE t.tid IN () AND n.status = 1 ORDER BY sticky DESC, created DESC LIMIT 5 in /home/path/to/html/includes/database.mysql.inc on line 66.

Is there some documentation on the node access table? I want to know where the gid links up with the user id. Also what realm means. I'm looking to creating my own access control for a custom application and I could really use the help.

These are the fields:

nid
gid
realm
grant_view
grant_update
grant_delete

Thanks.

Is there a way to make a module do this:

When viewing a node of a category, automatically show the recent nodes of that category?

Hi !

I have developped a module that allow to make a captive portal with drupal (in combinaison with chillispot).
Image : chillispot, drupal, multi-site... Yes !

I'm still interesting in having such a module, but I cannot continue his developpement for 2 main reasons :

First time submission. Submitted a new project using Creat Content -> Project. Now I don't see any mention of the fact that a new project has been submitted. No email, no "pending" status, just nothing. It is as if the submission has disappeared into thin air?

Are we supposed to be able to see the submitted project in a pending queue while await approval?

Thanks.
