Member Function Documentation

find_users

(

$

search

)

Search the database for users matching the $search string, and any other conditions that apply. The SQL for testing whether a user matches the search string should be obtained by calling the search_sql method.

This method is used both when getting the list of choices to display to the user, and also when validating a list of users that was selected.

When preparing a list of users to choose from ($this->is_validating() return false) you should probably have an maximum number of users you will return, and if more users than this match your search, you should instead return a message generated by the too_many_results() method. However, you should not do this when validating.

If you are writing a new user_selector subclass, I strongly recommend you look at some of the subclasses later in this file and in admin/roles/lib.php. They should help you see exactly what you have to do.

Parameters:

string

$search

the search string.

Returns:

array An array of arrays of users. The array keys of the outer array should be the string names of optgroups. The keys of the inner arrays should be userids, and the values should be user objects containing at least the list of fields returned by the method required_fields_sql(). If a user object has a ->disabled property that is true, then that option will be displayed greyed out, and will not be returned by get_selected_users.

Reimplemented from user_selector_base.
