使用 CodeIgniter 加载视图文件夹外的视图 [英] Loading view outside view folder with CodeIgniter

问题描述

我需要从以下范围之外加载视图:

I have the need to load a view from outside the scope of:

$this->load->view();

似乎在 base/application/views 目录下工作.如何从 /application/ 目录之外访问视图?

which appears to work from base/application/views directory. How can I access a view from outside the /application/ directory ?

我想我将不得不扩展 CI_Loader 类 这是最好的方法吗?

I assume i will have to extend the CI_Loader class would this be the best way forward ?

我还找到了保存 view_paths 的数组:

I have also found the array which holds the view_paths:

// base/system/core/Loader.php 
// CI_Loader 
 /**
 * List of paths to load views from
 *
 * @var array
 * @access protected
 */
protected $_ci_view_paths       = array();

但是上面所有声明变量的注释让我卡住了

but the comment above all the declared variables has got me stuck

// All these are set automatically. Don't mess with them.

任何关于从这里去哪里的想法将不胜感激:-)

Any ideas on where to go from here would be greatly appreciated :-)

推荐答案

不知道是不是正确的方法，但是有效 :)

Don't know whether it's a correct way, but it works :)

<?php

class MY_Loader extends CI_Loader {

  function ext_view($folder, $view, $vars = array(), $return = FALSE) {
    $this->_ci_view_paths = array_merge($this->_ci_view_paths, array(APPPATH . $folder . '/' => TRUE));
    return $this->_ci_load(array(
                '_ci_view' => $view,
                '_ci_vars' => $this->_ci_object_to_array($vars),
                '_ci_return' => $return
            ));
  }

}

?>

然后你想要一个外部视图文件，假设它在第三方文件夹中

application/third_party/my_new_view.php

Hello : <?php echo $my_name; ?>

然后在控制器中调用您的新视图

ext_view 是您的新视图加载器方法，

Then call your new view in the controller

ext_view is your new view loader method,

• 第一个参数:应用程序中的文件夹
• 第二个参数:视图名称
• 第三个参数:变量数据等等...

$view_data = array('my_name' => 'dino');
$this->load->ext_view('third_party', 'my_new_view', $view_data);

如果一切正常.它会输出
