URL重写，包括标题 [英] URL Rewriting including title

问题描述

最初，我成功使用id重写了网址

带有htaccess代码：

  RewriteRule ^ link /（[[0-9] +）\.html $ sub_index.php？link_id = $ 1 
  

和链接代码

  a href = link / id.html> 
  

显示成功：

然后我尝试使网址如下：
mysite.com/link/Trekking in Nepal / 6.html
其中 Trekking in Nepal是数据库中的标题

我写了 htaccess代码：

  RewriteRule ^ link /（[a-zA- Z0-9 _-] +）/（[0-9] +）\.html $ sub_index.php？link_id = $ 1 
  

和链接代码：

  a href = link / title / id.html> 
  

我无法成功地将URL重写为所需格式并获得消息
请求的URL在服务器上找不到

另外，当我在其他网站上搜索时，我没有看到空格，标题的写法是尼泊尔徒步旅行。 / p>

我想知道，需要帮助

谢谢

解决方案

首先，您的重写代码不正确：

  RewriteRule ^ link /（[ a-zA-Z0-9 _-] +）/（[0-9] +）\.html $ sub_index.php？link_id = $ 1 
  

您的link_id为$ 2，标题为$ 1。因此，您应该使用：

  RewriteRule ^ link /（[[a-zA-Z0-9 _-] +）/（[0 -9] +）\.html $ sub_index.php？link_id = $ 2 
  

然后您应该使用标题的子函数，因此对URL更友好。我用这样的东西：

  function slug（$ string，$ spaceRepl =-）{
 //替换为&带有和 
 $ string = str_replace（&， and，$ string）;的char 
 
 //删除任何字符，但字母，数字，空格和_，-
 $ string = preg_replace（ / [^ a-zA-Z0-9 _-] /， ，$ string）; 
 
 //可选：使字符串小写
 $ string = strtolower（$ string）; 
 
 //可选：删除双精度空格
 $ string = preg_replace（ / [] + /，，$ string）; 
 
 //用替换
替换空格$ string = str_replace（，$ spaceRepl，$ string）; 
 
返回$ string; 
} 
  

sl（尼泊尔徒步旅行）将是尼泊尔徒步旅行，因此您的链接将是：

  /link/trekking-in-nepal/6.html 
  

应该可以然后用您的重写代码。

此外，我想这样重写链接：

  /link/trekking-in-nepal-6.html 
  

为此使用以下命令：

  RewriteRule ^ link /（[[a-zA-Z0-9 _-] +）-（[0- 9] +）\.html $ sub_index.php？link_id = $ 2 
  

祝您好运！

Initially i succeed to rewrite the url using id

with the htaccess code:

RewriteRule ^link/([0-9]+)\.html$ sub_index.php?link_id=$1 

and link code

a href="link/id.html"> 

It displays successfully :

Then i tried to make url like this: mysite.com/link/Trekking in Nepal/6.html where "Trekking in Nepal" is a title in database

I wrote htaccess code:

RewriteRule ^link/([a-zA-Z0-9_-]+)/([0-9]+)\.html$ sub_index.php?link_id=$1 

and link code:

a href="link/title/id.html">

I cannot successfully rewrite my url to the desired format and get the message The requested url is not found on the server

Also when i searched in other sites, i didn't see space, the title is written like "Trekking-in-Nepal".

I am wondering, need help

Thanks

解决方案

First, your rewrite code is not correct:

RewriteRule ^link/([a-zA-Z0-9_-]+)/([0-9]+)\.html$ sub_index.php?link_id=$1

Your link_id is $2, your title is $1. So you should use:

RewriteRule ^link/([a-zA-Z0-9_-]+)/([0-9]+)\.html$ sub_index.php?link_id=$2

Then you should use a slug function for your title, so it's more url friendly. I use something like this:

function slug($string, $spaceRepl = "-") {
  // Replace "&" char with "and"
  $string = str_replace("&", "and", $string);

  // Delete any chars but letters, numbers, spaces and _, -
  $string = preg_replace("/[^a-zA-Z0-9 _-]/", "", $string);

  // Optional: Make the string lowercase
  $string = strtolower($string);

  // Optional: Delete double spaces
  $string = preg_replace("/[ ]+/", " ", $string);

  // Replace spaces with replacement
  $string = str_replace(" ", $spaceRepl, $string);

  return $string;
}

slug("Trekking in Nepal") will be trekking-in-nepal, so your link will be:

/link/trekking-in-nepal/6.html

It should work then with your rewrite code.

Also, I like to rewrite my links like this:

/link/trekking-in-nepal-6.html

For this I use the following:

RewriteRule ^link/([a-zA-Z0-9_-]+)-([0-9]+)\.html$ sub_index.php?link_id=$2

Good luck!
