codeigniter：加载多个视图 [英] codeigniter: loading multiple views
问题描述
我想分配一个变量$ layout_data ['navigation'] = $ this-> load（'layout / navigation'）
导航只是一个列表。
i want to assign a variable $layout_data['navigation']=$this->load('layout/navigation') navigation is just a list. when i pass this variable to my layout the list comes at the top.
这里是我的代码：
htaccess
RewriteEngine On
RewriteBase /ci/
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /ci/index.php/$1 [L]
控制器主页
<?php
class Home extends CI_Controller{
function index() {
$layout_data['navigation']=$this->load->view('navigation');
$this->load->view('layout/main',$layout_data);
}//end of index
}//end of class
?>
布局/导航（其视图）
<li><a href="#"><span>About Us</span></a></li>
<li><a href="#"><span>Objective</span></a></li>
layout / main（这是我的布局）
layout/main (this is my layout)

推荐答案
此行：
$layout_data['navigation'] = $this->load->view('layout/navigation');
...将立即输出视图。您需要将第三个参数设置为 TRUE ：
...will output the view immediately. You need to set the third parameter to TRUE:
$layout_data['navigation'] = $this->load->view('layout/navigation', NULL, TRUE);
第二个参数是你的数据数组，如果你需要它。您可以传入一个空字符串或 NULL （如果您不需要它）。
The second parameter is your data array, should you need it. You can pass in an empty string or NULL if you don't need it.

将数据视图作为数据返回
有一个第三个可选参数允许你改变
函数的行为，作为字符串，而不是发送
它到您的浏览器。如果要以某种方式处理数据
，这可能很有用。如果将参数设置为true（boolean），它将返回
数据。默认行为为false，将其发送到浏览器。
如果您想要返回数据，请记住将其分配给变量：
Returning views as data
There is a third optional parameter lets you change the behavior of the function so that it returns data as a string rather than sending it to your browser. This can be useful if you want to process the data in some way. If you set the parameter to true (boolean) it will return data. The default behavior is false, which sends it to your browser. Remember to assign it to a variable if you want the data returned:
