codeigniter view 试图里再引入view视图

PHP

引言：

$this->load->view('header'); 那么在视图header里面再来一个$this->load->view('menu');
显然这个会产生错误，以下是解决方案~~

A lot of new CodeIgniter users have at one point asked, "How to load a view within another View?"

To load a view within another view. We can also use the same method we used in the controller to load the "primary" view.

Php代码

1. <?php $this->load->view('header');?>
2. <div>
3. <p>This is the content</p>
4. </div>
5. <?php $this->load->view('footer');?>

<?php $this->load->view('header');?><div><p>This is the content</p></div><?php $this->load->view('footer');?>

Some coders might desire not to put $this->load->view() in the view. An alternative is to create a helper for loading views.

Php代码

1. // load_view_helper.php
2. if ( ! function_exists('load_view'))
3. {
4. function load_view($view, $vars = '', $return = FALSE)
5. {
6. $CI =& get_instance();
8. return $CI->load->view($view, $vars, $return);
9. }
10. }

// load_view_helper.phpif ( ! function_exists('load_view')){function load_view($view, $vars = '', $return = FALSE){$CI =& get_instance();return $CI->load->view($view, $vars, $return);}}

Add this to the helper array:

Php代码

1. $autoload['helper'] = array('load_view');

$autoload['helper'] = array('load_view');

And you're all set! To use:

Php代码

1. <?php load_view('header');?>
2. <div>
3. <p>This is the content</p>
4. </div>
5. <?php load_view('footer');?>

<?php load_view('header');?><div><p>This is the content</p></div><?php load_view('footer');?>

There are still tons of alternatives out there. One that is recommended is using Colin William's Template Library. Our example is one of the simplest.
