A list of renderable components to be used with |output renderers.
user_picture
An avatar for a given user object, which can be rendered after being constructed directly:
$userpic1 = new user_picture($USER);
$OUTPUT->render($userpic1);
Or by using a helper method in the core renderer (preferred):
$options = array( "visibletoscreenreaders" => false );
$userpic2 = $OUTPUT->user_picture($USER, $options);
The user object should have the following fields:
id
picture
imagealt
firstname
lastname
If the object does not have these fields, the db will be queried with significant performance implications. A list of these fields can be obtained from user_picture::fields() for the purposes of getting values ahead of time if necessary.
The following options can be set on the user_picture, either by changing each field after construction or by passing in an associative array as the second argument.
$userpic->courseid = $this->page->course->id; // course id of user profile in link
$userpic->size = 35; // size of image
$userpic->link = true; // make image clickable - the link leads to user profile
$userpic->popup = false; // open in popup
$userpic->alttext = true; // add image alt attribute
$userpic->class = "userpicture"; // image class attribute
$userpic->visibletoscreenreaders = true; // whether to be visible to screen readers
