CodeIgniter中的页眉和页脚

这是我的工作：

<?phpclass MY_Loader extends CI_Loader {    public function template($template_name, $vars = array(), $return = FALSE)    {        $content  = $this->view('templates/header', $vars, $return);        $content .= $this->view($template_name, $vars, $return);        $content .= $this->view('templates/footer', $vars, $return);        if ($return)        { return $content;        }    }}

对于CI 3.x：

class MY_Loader extends CI_Loader {    public function template($template_name, $vars = array(), $return = FALSE)    {        if($return):        $content  = $this->view('templates/header', $vars, $return);        $content .= $this->view($template_name, $vars, $return);        $content .= $this->view('templates/footer', $vars, $return);        return $content;    else:        $this->view('templates/header', $vars);        $this->view($template_name, $vars);        $this->view('templates/footer', $vars);    endif;    }}

然后，在您的控制器中，这就是您要做的一切：

<?php$this->load->template('body');
