RewriteRule不起作用.htaccess

Question

So I have this .htaccess:

RewriteEngine On
RewriteRule ^([^/]*)/$ /brand.php?brand=$1 [L]

index.php

<a href="/brand.php?brand=audi">audi</a>

brand.php

<?php
    if(isset($_GET['brand'])) {
        echo "brand is ".$_GET['brand'];
    } else {
        echo "no brand selected";
    }
?>

according to http://www.generateit.net/mod-rewrite/index.php it should be working.

When you click the link, your url will look like domain/brand.php?brand=audi . But I want it to look like domain/audi/ . It works fine, so I thought. But when you type domain/asdvasdvasdvkasdv/, it will just say: brand is asdvasdvasdvkasdv instead of no brand selected , since there was never a brand posted to brand.php.

Answer 1

Your rewriteRule only maps /bradname/ to the old url /brand.php?brand=brandname . To redirect your old url to the new one, you need an aditional rewriteRule. Add the following before your existing RewriteRule

RewriteEngine on


#1)old to new uri handler


RewriteCond %{THE_REQUEST} /brand\.php\?brand=([^\s]+) [NC]
RewriteRule ^ /%1/? [L,R]
#2)Your new to old uri handler

This will externally redirect /brand.php?brand=brandname to /brandname/ .

Answer 2

Fixed

There are a couple of ways to fix this problem, but I think this is the best one:

.htaccess

RewriteEngine On
RewriteRule ^brand/([^/]*)/$ /brand.php?brand=$1 [L]

html

<a href="/brand/audi/">audi</a>

You will need to link to a subdirectory /brand/ which represents brand.php. In brand.php you will simply check if the value of brand is in the database.

You will need to link to /brand/brandname/ in order to get brand.php. If you use /brand.php?brand=brandame as a link, the URL will not be rewritten.

这个怎么样？

RewriteRule path/brand.php?brand=(.*)/ path/$1/
