Come together with the global Drupal community in Rotterdam, 28 Sept – 1 Oct 2026. Sessions, contribution, connection, and Early Bird savings until 8 June.I was trying to re-view a patch that dealt with the forums earlier and came across this bug.
Steps to reproduce this error.
1. Enable forum module
2. Create a new forum
3. Create a new container
4. Using the drag & drop interface at admin/build/forum nest the forum underneath the container and click save.
Result.
Notice: Undefined variable: parent in taxonomy_term_save() (line 399 of /Users/joe/Sites/drupal_dev/d7head_testing/modules/taxonomy/taxonomy.module).
PDOException: INSERT INTO {taxonomy_term_hierarchy} (tid, parent) VALUES (:db_insert_placeholder_0, :db_insert_placeholder_1) - Array ( [:db_insert_placeholder_0] => 54 [:db_insert_placeholder_1] => ) SQLSTATE[23000]: Integrity constraint violation: 1048 Column 'parent' cannot be null in taxonomy_term_save() (line 401 of /Users/joe/Sites/drupal_dev/d7head_testing/modules/taxonomy/taxonomy.module).The forum in question totally disappears afterwards as well. Yikes. Looks like #302412: DB TNG: Taxonomy.module is the culprit for reference, makes me think that we should really have tests for this functionality.
Attached patch fixes the issue, but does not include any tests.

eojthebraveReroll, still needs tests but I still haven't had a chance to fully wrap my head around it.
Comment #4
emmajane commentedThis is still a problem as of August 4. It doesn't just give an error, it seems to have completely eaten a forum (container still visible).
To replicate:
1. Create Forum.
2. Create container.
3. Reorder so that Container is parent, forum is nested.
4. Save.
5. Blank screen (not enough PHP?)
6. Refresh browser window.
7. Error appears, forum now missing (container present):
* Warning: include(/home/emmajane/websites/drupal/drupal7/HEAD/includes/maintenance-page.tpl.php): failed to open stream: No such file or directory in theme_render_template() (line 1145 of /home/emmajane/websites/drupal/drupal7/HEAD/includes/theme.inc).
* Warning: include(): Failed opening '/home/emmajane/websites/drupal/drupal7/HEAD/includes/maintenance-page.tpl.php' for inclusion (include_path='.:/usr/share/php:/usr/share/pear') in theme_render_template() (line 1145 of /home/emmajane/websites/drupal/drupal7/HEAD/includes/theme.inc).
8. Refresh again, error disappears, container present but forum is still missing.
Comment #5
emmajane commentedAnd more:
the forum I created is still present, but not showing up:
mysql> select * from taxonomy_term_data;
+-----+-----+----------+-------------------------------------+--------+
| tid | vid | name | description | weight |
+-----+-----+----------+-------------------------------------+--------+
| 1 | 2 | Cars | things that go on wheels with power | 0 |
| 2 | 2 | Vehicles | | 0 |
| 3 | 2 | Cars | | 0 |
+-----+-----+----------+-------------------------------------+--------+
3 rows in set (0.00 sec)
Vehicle is the container
Cars is the forum that keeps going missing when I reorder things.
