Full Version: SQL error when copying a category without parent
You're currently viewing a stripped down version of our content. View the full version with proper formatting.
When copying a category, and the new category doesn't have a parent forum, there's an SQL error because the negative value -1 is inserted into the unsigned integer field pid.

-Copy forum
-Source forum: some category
-Destination forum: copy to new forum
-Copy Forum Settings and Properties: No
-Forum type: Category
-Title: something
-Parent forum: none

Since the correct pid for categories without a parent is 0 when adding a new category the value -1 is changed to 0 before it's saved to the database.
But not when a category is copied.

Doing the same when copying a category would be an option to fix this error:
In admin/modules/forum/management.php lines 95-97:
    $new_forum = $from_forum;

change to:
    if ($mybb->input['pid'] < 0)
        $mybb->input['pid'] = 0;
    $new_forum = $from_forum;
