            $content  = $this->view('admin/common/header', $vars, $return);
            $content  = $this->view('admin/common/leftmenu', $vars, $return);
            $content  = $this->view('admin/common/topbar', $vars, $return);
            $content .= $this->view($template_name, $vars, $return);
            $content .= $this->view('admin/common/footer', $vars, $return);
            return $content;
        else:
            $this->view('admin/common/header', $vars);
            $this->view('admin/common/leftmenu', $vars);
            $this->view('admin/common/topbar', $vars);
            $this->view($template_name, $vars);
            $this->view('admin/common/footer', $vars);
        endif;
    }

回答1:

Your template method (and CI view method) awaits $vars as array, but you are passing only string.

Correct usage would be:

public function index() {
    $data = array(
        'title' => 'Hello Admin',
    );
    $this->load->template('admin/cmspages', $data);
}
