Error: include_once(): Failed opening './includes/unicode.entities.inc'

Question

I am working on a D6 site and I have created some fields programatically, and it looked like it worked fine (code below). The fields show up in the database and on the UI screen. However, I found that after adding these field types, when I tried editing data in that content type, it wouldn't save. Looking at the error logs, I saw this:

include_once(./includes/unicode.entities.inc): failed to open stream: No such file or directory in /srv/www/usni.utdev.com/htdocs/includes/unicode.inc on line 339.

and

include_once(): Failed opening './includes/unicode.entities.inc' for inclusion (include_path='.:/usr/share/php:/usr/share/pear') in /srv/www/usni.utdev.com/htdocs/includes/unicode.inc on line 339.

and I can't figure out why I could be causing these errors.

Answer 1

I'm not sure what is causing those errors, but that was not the issue. I found out that the issue was that I had been creating fields with field names longer than 32 characters, which Drupal doesn't like. I added a 32 character limit to the names, and everything worked fine.
