◆ reset_caches()

◆ reset_internal_users()

◆ search()

static core_user::search	(		$query,
		context_course	$coursecontext = `null`,
			$max = `30`,
			$querylimit = `5`
	)

static

Searches for users by name, possibly within a specified context, with current user's access.

Deciding which users to search is complicated because it relies on user permissions; ideally, we shouldn't show names if you aren't allowed to see their profile. The permissions for seeing profile are really complicated.

Even if search is restricted to a course, it's possible that other people might have been able to contribute within the course (e.g. they were enrolled before and not now; or people with system-level roles) so if the user has permission we do want to include everyone. However, if there are multiple results then we prioritise the ones who are enrolled in the course.

If you have moodle/user:viewdetails at system level, you can search everyone. Otherwise we check which courses you do have that permission and search everyone who is enrolled on those courses.

Normally you can only search the user's name. If you have the moodle/site:viewuseridentity capability then we also let you search the fields which are listed as identity fields in the 'showuseridentity' config option. For example, this might include the user's ID number or email.

The $max parameter controls the maximum number of users returned. If users are restricted from view for some reason, multiple runs of the main query might be made; the $querylimit parameter allows this to be restricted. Both parameters can be zero to remove limits.

The returned user objects include id, username, all fields required for user pictures, and user identity fields.

Parameters

string	$query	Search query text
context_course \| null	$coursecontext	Course context or null if system-wide
int	$max	Max number of users to return, default 30 (zero = no limit)
int	$querylimit	Max number of database queries, default 5 (zero = no limit)

Return values

array Array of user objects with limited fields

◆ update_picture()

static core_user::update_picture	(	stdClass	$usernew,
			$filemanageroptions = `array()`
	)

static

Updates the provided users profile picture based upon the expected fields returned from the edit or edit_advanced forms.

Parameters

stdClass	$usernew	An object that contains some information about the user being updated
array	$filemanageroptions

Return values

bool	True if the user was updated, false if it stayed the same.

◆ validate()

static core_user::validate ( $data )

static

Validate user data.

This method just validates each user field and return an array of errors. It doesn't clean the data, the methods clean() and clean_field() should be used for this purpose.

Parameters

stdClass | array $data user data object or array to be validated.

Return values

array|true::$errors array of errors found on the user object, true if the validation passed.
