HomeBackend DevelopmentPHP TutorialCI框架整合widget(页面格局)的方法_PHP

本文实例讲述了CI框架整合widget(页面格局)的方法。分享给大家供大家参考,具体如下:

在WEB开发过程中,我们免不了要输出视图文件,而通常视图文件又一般都少不了头部、左侧栏以及底部这些公共元素。

如何让整个项目开发在涉及视图套用时引入敏捷的思维,提高效率呢?就不得不提一下widget。承然你也大可以使用HMVC模型。

这里仅介绍下widget如何结合入CI框架中:

1、在类文件MY_Controller.php中添加调用方法:

/*
* 如果$name存在则调用widget类及widget方法
*@param string $name
*/
protected function widget ($name = '')
{
    if (isset($name) && $name != '')
    {
      require_once BASE_WIDGET.$name.'.php';
    }
}

2、定义widget类文件:

<&#63;php
/*------------
widget.php 组件包含自己的控制器,视图,模型(可以共用普通model)
*用来实现各页面都有的公共部分
@author crystal 20120106
--------------*/
class Widget extends MY_Controller
{
  private function __construct()
  {
    parent::MY_Controller();
  }
  /*** 获取当前类名*/
  private static function _getClass()
  {
    return __CLASS__;
  }
  public static function left()
  {
    $class = self::_getClass();
    $data['userinfo'] = MY_Controller::_getUserCookieInfo();
    $this->load->view('com/left.php',$data);
  }
}
&#63;>

3、在视图文件中调用(在相应的控制器中应该先调用父类控制中的widget方法):

<!--left sider -->
<div>
<&#63;php Widget::left();&#63;>
</div>
...
<!--/left sider -->

How does PHP type hinting work, including scalar types, return types, union types, and nullable types?How does PHP type hinting work, including scalar types, return types, union types, and nullable types?Apr 17, 2025 am 12:25 AM

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values ​​and handle functions that may return null values.
