如何使用htaccess代码在PHP中重写URL？

Question

I have a link like below:

In /country/search.php

<a href="<?php echo 'index.php?departments='.$value['department_id'].'&towns='.$value['town_id'].'&type='.$value['type_id'].'&id='.$value['id'] ?>">

When I use the below .htaccess code, it does nothing:

RewriteEngine On
RewriteRule ^([^/]*)/([^/]*)/([^/]*)/([^/]*)$ /country/index.php?departments=$1&towns=$2&type=$3&id=$4 [L] 

It does in the tool:

http://example.com/0/0/4/122

... but when I click that link it shows old URL again.

What is the problem here?

I'm generating that .htaccess code using this tool: http://www.generateit.net/mod-rewrite/

Answer 1

Replace your code with this:

Options +FollowSymLinks -MultiViews
# Turn mod_rewrite on
RewriteEngine On
RewriteBase /

# external redirect from actual URL to pretty URL
RewriteCond %{THE_REQUEST} ^[A-Z]{3,}\s/+(index\.php|)\?departments=([^\s&]*)&towns=([^\s&]*)&type=([^\s&]*)&id=([^\s&]*) [NC]
RewriteRule ^ %1/%2/%3/%4/%5? [R=301,L]

# internal forward from pretty URL to actual URL
RewriteRule ^([^/]*)/([^/]*)/([^/]*)/([^/]*)/?$ /country/index.php?departments=$1&towns=$2&type=$3&id=$4 [L,QSA]

I think you misunderstood what the rewrite rules are trying to achieve in this context.

Fe this rewrite rule

RewriteRule ^([^/]*)/([^/]*)$ /app.php?method=$1&arg=$2

Will ensure that a request to http://example.com/mymethod/myarg will be rewritten to

http://example.com/app.php?method=mymethod&arg=myarg

When you generate links from within your application you should know how you contstructed the rewrite rules and you have to build the link accordingly.

Original URL:

href="news.php?state="<?php echo $sql_res['state']?>"&country="<?php echo $sql_res['country']?>

Ideal URL:

/India/andhra%20Pradesh

And .htaccess code:

RewriteEngine On 

RewriteRule ^([^/]*)/([^/]*)$ /news.php?country=$1&state=$2 [L]
