Url redirection in PHP

Question

hi,

i am having a url like http://localhost/joomla/Joomla_1.5.7/index.php?option=com_content&view=section&layout=blog&id=3&Itemid=55

and i want to redirect this to http://localhost/joomla/Joomla1.5/index.php?option=com_content&view=section&layout=blog&id=3&Itemid=55

Not only this redirection but whenever i have anything next to Joomla_1.5.7/ i am trying to attach that to Joomla1.5 .. How to do this in PHP .... How to identify that the url contains something after Joomla_1.5.7 to get it??

is the content in my htaccess file but still it showed any changes in my site.

Answer 1

You could do this with an htaccess file like this:

RewriteEngine on
RewriteRule ^joomla/Joomla_1.5.7/(.*?)$ joomla/Joomla1.5/$1 [L,QSA]

But if you absolutely want to achieve it with PHP, put this in the old index.php:

header("Status: 301");
header("Location: http://localhost/joomla/Joomla1.5/index.php".(!empty($_GET) ? '?'.http_build_query($_GET) : ''));
exit;

Answer 2

If you have mod_rewrite, in your .htaccess you can put something along these lines:

RewriteEngine on

RewriteCond %{REQUEST_URI} ^/joomla/Joomla_1\.5\.7/.*
RewriteRule ^(.*)$ http://%{HTTP_HOST}/joomla/Joomla1.5/$1 [L]

Basically, it matches any incoming URL that starts with /joomla/Joomla_1.5.7/ and redirects it to /joomla/Joomla1.5/, with all the extra parameters intact, but the URL won't change in the user's address bar.

If you want the URL to change, you can change the last line to

RewriteRule ^(.*)$ http://%{HTTP_HOST}/joomla/Joomla1.5/$1 [R=301,L]

Hope this is what you're looking for!
