Module development and code questions

Hey all,

I just picked up the spajax module, loving it. I seriously recommend it to everyone, with some knowledge of JS

Anyway i thought of a good idea to actually use Ajax in Drupal without breaking these very reasonable rules, more specifically not breaking the back button. Ok enough blabbin on.

I create a node type module and write a form for it. I have another table for this type so I use mynode_insert and mynode_update function. But when I edit my content and update it, some fields in the custom table can be updated and some not. I dont know why...

I've created a custom node type, and I've created a custom template 'node-custom.tpl.php' file. I've been reading about all the default variables that are available for a node template (http://drupal.org/node/11816). Can someone explain how I might go about creating a new variable, that would be available in a node template, to store data from a custom field?

Example (in 'node-custom.tpl.php'):
<div class="customfield"><?php print $customfield ?></div>

This snippet (http://drupal.org/node/84162) no longer seems to function. Should something be changed within it ?

How can I add note directly in the database? I already done it with my database but after that when i create new node (in drupal) it alert error: " Dulicate node id". Please help me.

Drupal 4.6.10 and Drupal 4.7.4 now protect forms by default against cross site request forgeries.

Be sure to read about possible consequences for your 4.6 or 4.7 module.
