重写不起作用？

Question

I am trying to write a rewritrule in my htaccess file on my 000webhost account but I cannot find a way to make it work!

all the files are uploaded to the root directory (public_html). the .htaccess file is in the same directory as well.

in the URL address bar i get something like this: domain.com/index.php?city=London

I need this to change to domain.com/city/London

But nothing seem to work via htaccess file!

here is my htaccess code:

<IfModule mod_rewrite.c>
RewriteEngine on
RewriteBase /

RewriteRule ^city/([^/]*)$ /index.php?city=$1 [L]
</IfModule>

any help would be great.

Answer 1

Your htaccess work properly. In case, of user will visit the page domain.com/index.php?city=LondonYou you can redirect him. By header location.

 header("Location: city/".$_GET['city']);

And now you need just know, when is user access by htacces and when not. Just use some trick.

RewriteRule ^city/([^/]*)$ /index.php?city=$1&accessByHtaccess [L]

With condition.

 if(!$_GET['accessByHtaccess ']){
   header("Location: city/".$_GET['city']);
 }

To get proper 'nice urls', you'll need to redirect ugly url's to nice url's, and internally rewrite nice url's to the ugly, actually working, url's. You already have the internal rewrite.

From Apache 2.3.9 on, you can use the following solution. The END -flag is not available in earlier versions and will throw an internal server error when used. Change the R to R=301 to make the redirect permanent. Only do this when all redirects and rewrites are working as you want them, as browsers will cache permanent redirects. The END-flag will stop rewriting completely, and will prevent an infinite loop.

RewriteEngine on
RewriteBase /

RewriteCond %{QUERY_STRING} city=([^&]*)
RewriteRule ^index\.php$ /city/%1? [R,L]

RewriteRule ^city/([^/]*)$ /index.php?city=$1 [END]

In earlier versions of Apache, you'll need to use a hack. This works, because %{THE_REQUEST} is only available like this with external requests, not when the url is rewritten:

RewriteEngine on
RewriteBase /

RewriteCond %{THE_REQUEST} ^[A-Z]{3,}\s/index\.php\?city=(.*)\s [NC]
RewriteRule ^ city/%1? [R,L]

RewriteRule ^city/([^/]*)$ /index.php?city=$1 [L]

Please note that I can't test either RewriteRule on this computer, but I am fairly sure I didn't make a typo.
