Drupal Development

The best approach may be to avoid this entirely with proper information architecture. I always try to make these have meaning themselves, but certainly with not expecting most people to click on them anyway, this does not always make sense. Instead, the way Agaricer Kathleen did it for one project is simply to have each dropdown be a separate menu.

But let's say you are stubborn and don't like that approach or are too far down the path of a big old nested primary links menu. What do you do? Call Agaric, of course (or find this web page).

The big one, PHP.net itself

http://php.net

PHP.net has an excellent function search such that if you simply append the function name to the url (such as php.net/explode), it will serve up the PHP manual page with the specification and notes right away-- and if you use a function name that doesn't exist, it will provide a range of suggestions you might have meant.

Can't be as complicated as these people make it out to be?

One of Agaric's approaches, below. This foreach allows one to unset just one validation function associated with a form (and adds another one below) without replacing or overriding any other validation callbacks that might be associated with the form (by the initial or other modules).

Bad coding in a development partner's custom module was the culprit. It was overriding content_profile_registration's setting of a validation function (and every other module's, too).

Inside the custom module's implementation of hook_form_alter() lives the error:

http://api.drupal.org/api/function/field_info_field/7

field_info_field('field_name') returns an object or NULL.

Resolution

In short, resolve a conflict in favor of the outside repository.

The file can be a

mv offending.file ~/elsewhere
git checkout offending.file
