php/表达式引擎-将所有URL从一个URL段重定向到另一个URL段
我最近重拨了一个expression engine网站，虽然网站上每篇文章或每页的标题没有改变，但通往它们的路线却改变了。例如，在我之前： site.com/site/code_single/name-of-page 我现在有 site.com/main/code-item/name-of-pagephp/表达式引擎-将所有URL从一个URL段重定向到另一个URL段,php,.htaccess,codeigniter,redirect,expressionengine,Php,.htaccess,Codeigniter,Redirect,Expressionengine,我最近重拨了一个expression engine网站，虽然网站上每篇文章或每页的标题没有改变，但通往它们的路线却改变了。例如，在我之前： site.com/site/code_single/name-of-page 我现在有 site.com/main/code-item/name-of-page 如何设置重定向（使用表达式引擎标记或使用PHP/.htaccess），使所有与site/code\u single匹配的URL重定向到site/main/code项中相应的标题？如果需要PHP解决方
如何设置重定向（使用表达式引擎标记或使用PHP/.htaccess），使所有与site/code\u single匹配的URL重定向到site/main/code项中相应的标题？如果需要PHP解决方案，可以在执行任何其他代码（在main index.PHP顶部）之前调用此函数 我使用它来重新路由codeigniter URL，而不使重复的URL保持活动状态。如果使用routes.php，会发生什么 对于那些想知道为什么的人来说？谷歌喜欢301重定向，不喜欢双重内容。Codeigniter有一个漂亮的功能，可以创建自己的“路由”，这样你就可以在需要的地方使用自己的url。问题是，原来的“不想要的/丑陋的”url仍然可以访问，如果谷歌发现了这一点，你的页面在seo排名上会大幅下降。 发现这一点后，我试图在codeigniter中发现任何类型的301重定向功能，但每次都遇到了麻烦。htaccess会随着时间的推移重定向失败的时间（我不是唯一一个，stackoverflow充满了它） 所以，这就是为什么我决定写这篇文章的原因，要牢记速度，尽可能少的“花哨操纵”来完成工作 您必须在codeigniter的第一个index.php文件的顶部添加这些行

//Just keep copy pasting this. In the orig you do the url without domain to check.

谢谢-我想我在网上找到了一个很好的解决方案，其中包括让EE为301重定向动态生成URL列表：
在这里，一行.htaccess确实是最简单的解决方案
RedirectMatch ^/site/code_single/(.+)$ /main/code-item/$1 [L,R=301]
