how do I force the URL to include www.

[fwitt]

I have a script running that only works if it is accessed via the URL
http://www.example.com/script.php
and not if it is accessed via
http://example.com/script.php
how do I check the URL and insert the www. if it is missing?

This on SMF or a stand alone script?

If you want a stand alone script you got 2 options.
1. If you use apache and mod_rewrite is enabled you can use that to redirect.

2. Use php to detect current url and redirect. But if the script can't run at all without the www meaning the php script wont process at all this wont work..

[fwitt]

its a script thats calling SSI functions, if the www. isnt in the url no info is returned by some of the SSI functions the rest of the php script works fine with or without the www.

option 2 is the one I'm aiming for but I cant find the php function the returns the current url, I've probly overlooked the obvious here.

[fwitt]

I tried $_SERVER['SERVER_NAME'] but this returns the www. whether it is in the URL or not.

[fwitt]

found it $_SERVER['HTTP_HOST'] seems to do what i want.

now to write the script...

You could fix this just by enable subdomain independent cookies in the administration center , as I am prety sure you've got cookie problems

this is the code i put at the top of the php file to force, the www. to appear.

Code Select Expand



//lets force the URL to include www. (some SSI functions dont work without it)
if ($_SERVER['SERVER_NAME'] !== $_SERVER['HTTP_HOST'])
{
  header('Location: http://' . $_SERVER['SERVER_NAME'] . $_SERVER['PHP_SELF'] . '?' . $_SERVER['QUERY_STRING']);
  exit;
}



for a file accessed at http://example.com/index.php?action=test this redirects to http://www.example.com/index.php?action=test it does not include the file path if the file is not in your domains root, but that can be added between $_SERVER['SERVER_NAME'] and $_SERVER['PHP_SELF'] if needed.

I will have to play with that on my test site, it definatly would have been an easier solution, but I learnt stuff by doing it the other way and thats always good.

there's something wrong with the php code, it adds " index.php? " when first visiting the website at the end of the web address.. removing $_SERVER['QUERY_STRING'] should fix this problem but i dont know what this will cause to other links, i wont be using the code until i find a better code for this, i think taken the nuke code for this will do the trick, i'll post back if it works.

[fwitt]

o thats easy to fix

if ($_SERVER['SERVER_NAME'] !== $_SERVER['HTTP_HOST'])
{
  $target = 'Location: http://' . $_SERVER['SERVER_NAME'] . $_SERVER['PHP_SELF'];
  if (!empty($_SERVER['QUERY_STRING']))
    $target = $target . $_SERVER['QUERY_STRING'];
  header($target);
  exit;
}

This is done in an .htaccess file using a rewriterule.

[Daniel15]

Yep, the best way to go about this is via a mod_rewrite rule in .htaccess. Do something like:

Code Select Expand


RewriteEngine on
RewriteCond %{HTTP_HOST} !^www.dansoftaustralia.net$ [NC]
RewriteRule ^(.+)$ http://www.dansoftaustralia.net/$1 [R=permanent]

Replace www.dansoftaustralia.net with the correct domain, of course. This will redirect all access to the www.[domain] domain, using a 301 (permanent) redirect

[kegobeer]

I've never seen [R=permanent], only [R].  Although it may work, if you chain options I don't think =permanent is permitted.

[Daniel15]

Yeah, [R=permanent] works (as well as [R=301])
See the Apache documentation (http://httpd.apache.org/docs/2.0/mod/mod_rewrite.html#rewriterule)

'redirect|R [=code]' (force redirect)
Prefix Substitution with http://thishost[:thisport]/ (which makes the new URL a URI) to force a external redirection. If no code is given, a HTTP response of 302 (MOVED TEMPORARILY) will be returned. If you want to use other response codes in the range 300-400, simply specify the appropriate number or use one of the following symbolic names: temp (default), permanent, seeother.
