I am trying to create a form that uses a dynamic type of redirect. I was hoping for a php or javascript solution (if it even exists)

For example:

I will have two radio buttons (one is YES and the second one is NO). I will also have a submit button labeled NEXT.

If YES is pressed and the Next Button is selected the user would go to Page 1.

If NO is pressed and the Next Button is selected the user would go to Page 2.

Thanks in advance experts

Try this:
<html>
<head>
 <script type="text/javascript">
   function redirect(){
     var yes = document.getElementById('yes').checked;
  
     if(yes) window.location="page1.html";
     else window.location="page2.html";
 
   }
 </script>
</head>
<body>
   <input type="radio" id="yes" /> Yes <br />
   <input type="radio" id="no"  /> No <br />
   <input type="button" value="NEXT" onclick="redirect()" />
</body>
</html>

Sorry, one error in my code.  add the name attribute to both radio buttons.  Make them the same.

You may want to process other information in the form, and to do that you may want to run a script on the server-side, instead of on the client-side in JavaScript.  If that is the case, this code will show you the way to do the dynamic redirect.

// REDIRECT AND EXIT
    header("Location: $page");
    exit;
    
} // END OF PHP - PUT UP THE FORM WITH THE RADIO BUTTONS
?>
 
<form method="post">
<input type="radio" name="my_radio" value="y" />YES (PAGE 1)<br />
<input type="radio" name="my_radio" value="n" />NO (PAGE 2)<br />
<input type="submit" />
</form>
