Create a script that displays a form allowing the user to select one of three url - and then jumps to the relevant store based on the user's choice.
Use the Location: header to redirect the browser to the appropriate store after the form has been submitted.
You need to make sure that the script doesn't output anything before the Location: header:
<?php if (isset($_POST[" submitButton" ])) { switch ($_POST[" store" ]) { case" .com" : header("Location: http://www.book2s.com/" ); break;//from w w w .j a va 2s .com case" .ca" : header("Location: http://www.google.ca/" ); break; } } else { displayForm(); } function displayForm() { ?> <html> <head> <title>Amazon Store Selector</title> </head> <body> Amazon Store Selector <form action="" method="post"> <div> <label for="store">Choose your Amazon store:</label> <select name="store" id="store" size="1"> <option value=".com">book2s.com</option> <option value=".ca">google.ca</option> </select> <div style="clear: both;"> <input type="submit" name="submitButton" id="submitButton" value= " Visit Store" /> </div> </div> </form> <?php } ?> </body> </html>
