How to redirect www.example.com/index.php to www.example.com in XOOPS

Aim:

If a webpage on www.example.com/index.php shows the same content as www.example.com/ , you may consider a redirect in order to improve your site's ranking in search engines. The aim of this howto is to redirect this page.

How to redirect www.example.com/index.php to www.example.com in XOOPS:

Add something like this to your PHP file:

// redirect to avoid double content
if(strpos(getenv('REQUEST_URI'), '/index.php') === 0)
{
header("HTTP/1.1 301 Moved Permanently");
header("Location: http://www.example.com/");
}

This should do the redirect.

In case you have a multilingual site running on the XLanguage module, the situation will be slightly more complicated. You will have different index pages for each language, for example www.example.com/index.php?lang=en for English and www.example.com/index.php?lang=fr for French. In addition, the content of www.example.com depends on a cookie that stores the language preferences.

For SEO reasons, it is better to have one page per URL. Let's say you want to ensure that www.example.com/index.php?lang=en becomes www.example.com and www.example.com/index.php?lang=fr to www.example.com/fr/. In this case, make sure that this phase is included in your .htaccess file:

RewriteEngine On

and add something like this to your .htaccess file:

# English
RewriteRule ^en$ / [R=301]
RewriteRule ^en/$ / [R=301]
DirectoryIndex index.php?lang=en
# French
RewriteRule ^fr$ /fr/ [R=301]
RewriteRule ^fr/$ /index.php?lang=fr [QSA,L]

Finally, add something like this to your index.php file:

// redirect to avoid double content
if(strpos(getenv('REQUEST_URI'), '/index.php?lang=fr') === 0)
{
header("HTTP/1.1 301 Moved Permanently");
header("Location: http://www.example.com/fr/");
}
elseif(strpos(getenv('REQUEST_URI'), '/index.php?lang=en') === 0)
{
header("HTTP/1.1 301 Moved Permanently");
header("Location: http://www.example.com/");
}
elseif(strpos(getenv('REQUEST_URI'), '/index.php') === 0)
{
header("HTTP/1.1 301 Moved Permanently");
header("Location: http://www.example.com/");
}
