$name = JRequest::getString('name', ''); echo "Hello, {$name}!";
$email = JRequest::getString('email', '', 'POST'); if (filter_var($email, FILTER_VALIDATE_EMAIL)) { echo "Thank you for your email!"; } else { echo "Please enter a valid email address."; }In this example, the getString function is used to retrieve the "email" variable from the POST request. If no "email" variable is found, the default value of an empty string is used. The retrieved value is then passed through the filter_var function to check if it is a valid email address. Depending on the result, a customized message is outputted. Package Library: Joomla Framework
