在CI中加载页眉和页脚视图 [英] Load header and footer view in CI
问题描述
有没有任何方法加载视图'header'/'footer'而不调用 $ this-> load-> view('header')
或 $ this-> load-> view('footer')
在每个控制器?
Is there any way to load view 'header'/'footer' without calling $this->load->view('header')
or $this->load->view('footer')
in every controller? Maybe a template that can be use in every view?
推荐答案
这里有几个简单的方法让你开始:
Here are a couple simple approaches to get you started:
class Template {
function load($view)
{
$CI = &get_instance();
$CI->load->view('header');
$CI->load->view($view);
$CI->load->view('footer');
}
}

Usage in controller:
$this->template->load('my_view');
使用主视图文件:
Use a master view file:
<!-- views/master.php -->
<html>
<header>Your header</header>
<?php $this->load->view($view, $data); ?>
<footer>Your footer</footer>
</html>
在控制器中:
$this->load->view('master', array(
'view' => 'my-view-file',
'data' => $some_data
));
我更喜欢
类方法,因为它很容易添加方法附加模板区域,加载javascript文件,以及任何其他您需要的。我也喜欢根据被调用的方法自动选择视图文件。像这样:
I prefer the Template
class approach, as it's easy to add methods to append templates areas, load javascript files, and whatever else you need. I also prefer to automatically select the view file based on the method being called. Something like this:
if ( ! isset($view_file)) {
$view_file = $CI->router->fetch_class().'/'.$CI->router->fetch_method();
}
这将加载 views / users / index.php
如果控制器 Users
且方法是 index
。
This would load views/users/index.php
if the controller is Users
and the method is index
.
