Module development and code questions

I am making a module using hook_nodeapi.
When I try to echo debug info for operations "update" or "insert", nothing outputs for any node type. So I wonder whether this hook is being properly called upon update & insert of a node. I can echo debug info properly for other operations ("settings", "validate" printing OK). Code:

HI, I am fairly new to Drupal but have installed several dozen sites, and just recently have come up with the need to bulk import entries to a flexinode. I remember reading that there are some problems with directly entering posts to the MySQL database. Is this possible to do.

I tried using the Node_Import module but have not be able to get it to work. I point it to the CSV file and click Import, the page refreshes but no data is imported. Perhaps I have missed some setting for it.

Hi,

I have problem with Drupal 4.6.2 (Linux system : Ubuntu 5.04).

I can't write any content on my drupal website, neither login nor logout fron the drupal. I can't see any content or do anything.

I've got this message :

Fatal error: Can't open file: 'variable.MYI'. (errno: 145) query: SELECT * FROM variable in
/var/www/drupal462/includes/database.mysql.inc on line 66

I was working on my drupal website (on local), suddently everything is blocked. I stopped the system by using the power button. I couldn't restart the system. Then, I try again and the system asked me to do this :

mount -n -o remount, rw /

then, the system asked me to lauch fsck to clear problem on i_blocks and inode. I said yes to valide.

Some inodes and blocks are deleted. After that I restart the system and that works.

I launched the drupal website and this message appears :

user error: Can't open file: 'variable.MYI'. (errno: 145)
query: SELECT * FROM variable WHERE name like 'event_nodeapi_%' in /var/www/drupal462/includes/database.mysql.inc on line 66.

I can't create content and anything else on my website. This message appears :

Fatal error: Can't open file: 'variable.MYI'. (errno: 145) query: SELECT * FROM variable in /var/www/drupal462/includes/database.mysql.inc on line 66

Hi,

I'm having some problem with AJAX form_autocomplete functionality from the CVS build.

When I navigate to my page with the form_autocomplete it works fine! But when I navigate to another page and again to the one with the form_automplete it doen't work anymore... The form_autocomplete field keeps loading and loading. Looks like a infinitive loop.

I've put in the code I'm using.
The form_autocomplete functionality is great but it doesn't look stable. Any help welcome.

Regards,
Marcel

Hi there,
I'm looking to allow my registered users to select which RSS feeds will be displayed on their page. Anyone have ideas?

Thanks!

I have several customers with Drupal versions 4.5 and 4.6. Now I want to write a module that is compatible with both versions. Is there a way to check the drupal version so I can branch to the correct function calls?
For example checking the version to determine if I should use module_get_path or drupal_get_path.

What I don't want to do is fiddle with a version control system and having two branches.
