TP5 determines between mobile phone and PC

This article mainly introduces the judgment of mobile phone and PC in TP5. It has certain reference value. Now I share it with you. Friends in need can refer to it.

Judgement of mobile phone and PC in TP5

1. Use a custom determination method

1. First write the parameters used to determine device login in the application>common.php public file ismobile method:

   function ismobile()
   {
       // 如果有HTTP_X_WAP_PROFILE则一定是移动设备
       if (isset ($_SERVER['HTTP_X_WAP_PROFILE']))
           return true;
   
       //此条摘自TPM智能切换模板引擎，适合TPM开发
       if (isset ($_SERVER['HTTP_CLIENT']) && 'PhoneClient' == $_SERVER['HTTP_CLIENT'])
           return true;
       //如果via信息含有wap则一定是移动设备,部分服务商会屏蔽该信息
       if (isset ($_SERVER['HTTP_VIA']))
           //找不到为flase,否则为true
           return stristr($_SERVER['HTTP_VIA'], 'wap') ? true : false;
       //判断手机发送的客户端标志,兼容性有待提高
       if (isset ($_SERVER['HTTP_USER_AGENT'])) {
           $clientkeywords = array(
               'nokia', 'sony', 'ericsson', 'mot', 'samsung', 'htc', 'sgh', 'lg', 'sharp', 'sie-', 'philips', 'panasonic', 'alcatel', 'lenovo', 'iphone', 'ipod', 'blackberry', 'meizu', 'android', 'netfront', 'symbian', 'ucweb', 'windowsce', 'palm', 'operamini', 'operamobi', 'openwave', 'nexusone', 'cldc', 'midp', 'wap', 'mobile'
           );
           //从HTTP_USER_AGENT中查找手机浏览器的关键字
           if (preg_match("/(" . implode('|', $clientkeywords) . ")/i", strtolower($_SERVER['HTTP_USER_AGENT']))) {
               return true;
           }
       }
       //协议法，因为有可能不准确，放到最后判断
       if (isset ($_SERVER['HTTP_ACCEPT'])) {
           // 如果只支持wml并且不支持html那一定是移动设备
           // 如果支持wml和html但是wml在html之前则是移动设备
           if ((strpos($_SERVER[&#39;HTTP_ACCEPT&#39;], &#39;vnd.wap.wml&#39;) !== false) && (strpos($_SERVER[&#39;HTTP_ACCEPT&#39;], &#39;text/html&#39;) === false || (strpos($_SERVER[&#39;HTTP_ACCEPT&#39;], &#39;vnd.wap.wml&#39;) < strpos($_SERVER[&#39;HTTP_ACCEPT&#39;], &#39;text/html&#39;)))) {
               return true;
           }
       }
       return false;
   }

2. Then rewrite the fetch method in the base class controller Base of the front-end index module in application>index>controller>Base.php #

   /**
    *加载模板输出（电脑和手机）
    * @accessprotected
    * @paramstring$template模板文件名
    * @paramstring$mobiletemplate手机模板文件名
    * @paramarray$vars模板输出变量
    * @paramarray$replace模板替换
    * @paramarray$config模板参数
    * @returnmixed
    */
   protected
   function fetch($template = '', $mobiletemplate = '', $vars = [], $replace = [], $config = [])
   {
       if (ismobile()) {
           return $this->view->fetch($mobiletemplate, $vars, $replace, $config);
       } else {
           return $this->view->fetch($template, $vars, $replace, $config);
       }
   }

3. Finally, in

   application>index>controller>Index, the path to the PC side and the path to the mobile side are passed in to the method index that inherits the controller Index of the base class Base. That’s it.

   return $this->fetch('default/index/index','mobile/index/index');

   The front

   default/index/index is the path corresponding to the PC side, and the following mobile/index/index is the path corresponding to the mobile side.

2. Use the judgment method that comes with TP5 (recommended, optimized)

We can see from the above method that although It works, but it is very cumbersome to pass in two paths every time.

##First write the constants used to determine device login in the
1. application>common.php

   public file VIEW_PATH ：

   if (\think\Request::instance()->isMobile()) {
       define('VIEW_PATH', __DIR__ . '/../application/index/view/mobile/');
   } else {
       define('VIEW_PATH', __DIR__ . '/../application/index/view/default/');
   
   }

Then replace the template variables in the configuration file config.php of the
2. application>index>config.php

   module index: <pre class='brush:php;toolbar:false;'>return [ &quot;template&quot;=&gt;[ // 模板路径 &amp;#39;view_path&amp;#39; =&gt; VIEW_PATH, ], ];</pre>

Finally, you only need to fetch a path directly in the controller method.

3. return $this->fetch();

Tip: The directory structure of the front page is as shown in the figure:

Note that the directory structure under default and mobile is consistent
