代码Igniter - 检测浏览器的最佳方式

问题描述

我想将某个年龄的所有浏览器分流到自己的网页。什么是最好的方法这样做？也许在头部中的一些JS包裹在：

 < !- [if lte IE 7] 
< script type =text / javascript> 
 window.location =/ unsupported-browser /; 
< / script> 
<！[endif]  - > 
  

不应该将浏览器发送到：我有一个基本的控制器和视图来处理它？是这么简单吗？

解决方案

使用和到该页面。

但更重要的是，为什么不允许IE用户访问您的网站？是由于CSS还是其他问题？

代码：

  $ this-> load-> helper（'url'）; 
 $ this-> load-> library（'user_agent'）; 
 
 if（$ this-> agent-> browser（）=='Internet Explorer'and $ this-> agent-> version（）< = 7）
 redirect（'/ unsupported-browser'）;

如前所述;如果您想在整个网站上执行此操作，请在 MY_Controller 中运行，并确保添加 $ this-> uri-> segment（1）！='unsupported-browser '作为避免重定向循环的额外条件。
 
I want to shunt all browsers of a certain age off to their own page. What is the best method for doing this? Perhaps some JS in the header that is wrapped in :
 <!--[if lte IE 7 ]>
    <script type="text/javascript">
        window.location = "/unsupported-browser/";
    </script>
    <![endif]-->
Shouldn't the above send the browser to: http://example.com/unsupported-browser/ where I have a basic controller and view to handle it? Is it that simple?
 解决方案 
Do this in php instead. Use the user_agent class and redirect to that page.
But more importantly, why don't you allow IE users access to your site? Is it due to CSS or something else?
Code:  
$this->load->helper('url');
$this->load->library('user_agent');

if ($this->agent->browser() == 'Internet Explorer' and $this->agent->version() <= 7)
    redirect('/unsupported-browser');
Edit:
As mentioned; if you want this over your entire site, run this in MY_Controller and make sure to add $this->uri->segment(1) != 'unsupported-browser' as an extra condition to avoid redirect loops.
