SENDING VALUES TO A SCRIPT Hidden form input type: Depending on the method, $_POST['do'] or $_GET['do'] will have a value "this" Recall that the GET method sends variables through the URL, so the form part can be skipped by appending the name=value pair to the URL: www.example.com/page.php?do=this
SENDING VALUES TO A SCRIPT Edit To append multiple values to a URL, use & between each name=value pair If a string is sent through a URL, it should be encoded for proper handling. Use the urlencode() function: $url= 'page.php?name='. urlencode('Sam Smith');
