When i open my page without www, like Domain.com in IE, images dont display, only when i type it with www infront...

So i try to fix that with this code, but no luck, any help?, i dont have .htaccess support?

Quote:

<?PHP
if ( substr ( $_SERVER['SERVER_NAME'], 0, 4 ) != 'www.' )
{
header ( 'location: http://www.' . $_SERVER['SERVER_NAME'] );
exit ();
}
?>

You're best off doing this with HTAccess, and resultantly a 301 redirect for SEO purposes. This can be achieved like so:

Thats impossible O.o are you using apache?

In that case then, the code you published is working perfectly fine. Unless your host has disabled htaccess on an individual basis, and your web server is running Apache, then you will have htaccess support. I don't know of any hosts these days that disable htaccess. Try getting in touch with them.

Are you suppressing warnings? Perhaps your header() has just failed. Could you copy the following code into your file directly before the if() construct and post the response here?

PHP Code:


			
//...

//firstly we check if there's already been output
if (headers_sent($file, $line)) {
  //okay, that was simple: the problem is that header() failed
  //now find out where the first output has been made
  echo 'Headers already sent in "' . $file . '" in line "' . $line . '"' . PHP_EOL;
} else {
  //substr ( $_SERVER['SERVER_NAME'], 0, 4 ) seems to be "www."
  var_dump ( $_SERVER['SERVER_NAME'] );
  echo PHP_EOL;
  var_dump ( substr ( $_SERVER['SERVER_NAME'], 0, 4 ) != 'www.' ) );
  print_r ( $_SERVER );
}

die();

//...

You could also try to replace "location" by "Location" so that it looks like:

PHP Code:


			
header('Location: http://www.example.com/');

Perhaps that's been an Internet Explorer specific problem. Have you already other browsers like the Mozilla Firefox or Opera?

Why do you redirect at all? Even better is to use a function which returns the URL to your script without the scriptname itself (You could also use a variable but functions can be used in different parts of your code - okay you could use the global/static keyword for that but I prefer functions or Singleton classes). So when you want to use an image just add getUrl() before the filename.
