Viewer Page Render Example

Using either Mouse Object constructor detailed above, a Message Viewer Page Class would look like:

class MessageViewer extends Page {
    function __construct() {
        parent::__construct("Message Viewer");
        $this->data = new MessageDB();
        $this->list = array();
    }

    function pre_render() {
        parent::pre_render();
        //handle deletes if a mission_id is presented
        if ($_REQUEST['delete']) { $this->handle_delete(); }

        $this->message = $this->data->read_lms_message();
        if (empty($this->message)) { $this->addError("No message associated with this message ID."); }
    }

    function body() {
        if (!empty($this->message)) {
            $this->data->update_message_read_time();
            $links = array(array(link => "default.php?appname=message-view&delete=1&message_id=" .
                     $this->data->get_message_id(), label => "Delete"));
            auto_render_view($this->data, '"' . $this->data->get_subject() . '"', "600px", $links);
        }
    }

    function handle_delete() {
        $this->data->delete_lms_message();
        my_redirect('default.php?appname=message-mgr');
    }
}
