Cookie help

I have a frustrsting problem that I hope is very easy to solve!

As an example, on various pages of my site I set a cookie called region, and give it one of 3 values: uk, usa, or jap. All I want to do is call the value already set to a cookie in the isset command. The code I keep coming across is:

Code:

if ( isset ($_COOKIE['region'] ) ) {
    header("Location: index.php");
}

But I want to find out what specific value is set, not just wether the cookie actually exists or not! How can I do this? Would it be something along the lines of:

Code:

 if ( isset ($_COOKIE['region'] $_VALUE['uk'] ) ) {
     header("Location: uk.php");
 } else if ( isset ($_COOKIE['region'] $_VALUE['usa'] ) ) {
      header("Location: usa.php");
} else if ( isset ($_COOKIE['region'] $_VALUE['jap'] ) ) {
      header("Location: jap.php");

Thanks.

The easiest way to do this would be to use $_SESSION data. Saves having to have multiple cookies as you can set it into the one session. I'm not sure how you have set it up, so i cant give you direct advice; However say you have a dropdown menu asking them to select what page they want to view (UK, USA or Jap) and once they have submitted that form, you direct them to a certain page depending upon what they selected; just do:

Code:


			
if(isset($_POST['submit'])) {
  $_SESSION['region'] = $_POST['region'];
}

That's just the basic grab the form data and store it into a session. Once it is stored, (Dont forget to session_start() first.) you have that session data set and then you can use a function to determine were to direct them. Eg:

Code:


			
function Region($Region) {
  if($Region == "UK") {
     header('location: uk.php');
  }
  elseif($Region == "USA") {
     header('location: usa.php'); 
  }
  elseif($Region == "Jap") {
     header('location: jap.php');
  }
  else {
     echo "Submit the form!";
  }
}

Then at the start of the page, execute the function. (I'm assuming you understand the code i used, thus i didn't go into too much explanation.). Hope it helped.
