How to show online users in PHP?

Php/javascript or other language experts out there.?

• I'm in the process of creating a filtered register page where users can choose what type of account they want (example : basic account or full account) which would show something like: <select name="utype"> <option select value"<?php echo $value['user_type'];?>"> <?php echo $value['ul_desc'];?></option> <?php } ?> </select> Ok so what I want to happen is whenever a user chooses among the given options on the list, a registration form will appear (note: I want the registration form to appear only after an option has been chosen) and I want the registration form to be different from each other whenever another option is chosen. So is it possible to make an "input type="text"" and an "input type="submit"" hidden only until an option is selected on the <select> list? If so, can you post any tutorial links here, I'd be very thankful to those who can!

• Answer:

  You would need Javascript to make it happen as soon as they click on an option in the select list. What you can do is have onChange="myFunction(value)" on the <select> and have Javascript show/hide the rest of the form depending on the value. This can all be done with basic Javascript, but if you're interested in more advanced animation, jQuery would be great for this as well.
