Here's a solution for you 🙂
HTML Form with the radio button that points to "navigation.php"
<form name="form1" method="post" action="navigation.php">
Go to login page:
<input type="radio" name="location" value="login.php">
<input type="submit" name="Submit" value="Submit">
The php page "navigation.php" that handles the redirection.
<?
//your url.. dont forget trailing slash!
$baseurl = "http://yoursite.net/";
$url = $_POST['location'];
$go = "$baseurl$url";
//redirect person to page.
header("Location: $go");
}
?>
