Module development and code questions

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.

Hi friends of the image module

Since there is no way to upload whole directories or archives into image galleries of drupal, I wrote a small command line tool in php5 to upload files from a local directory into a specified drupal gallery.

You can find the tool here on my homepage. The drupal relevant part has its own subdirectory. You have to edit drupal_upload.php and specify your user data, gallery-id (taxonomy-id), and the local directory containing the pics:

i want to create links in pages that when clicked on will result in a complete response (http header and body) sent to the client.

specifically, i want to send an extended m3u format playlist that will be generated dynamically (not stored on disc).

rather than hack it and create an external script that does it, i'd like to learn how this would be done drupal style.

i'm assumming i'd be writing a hook_* callback that would perform the task, but not sure which/how etc...
