Trouble Making Radio Buttons Sticky

[wktarin]

I've constructed a survey form, and I want to make the radio buttons sticky, so that if participants leave the page, they can return to find their answers still in tact. However, I can't seem to find the right code to make the radio buttons sticky. Below is the code I'm using. Any help would be appreciated.

<p>Do you enjoy web designing?<br />
	<input name="ans1" type="radio" value="yes" 
	 <?php if ($_GET["ans1"]=="yes") echo "checked=\"checked\""; ?>/>    
	  yes &nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 

	  <input name="ans1" type="radio" value="no" 
	 <?php if ($_GET["ans1"]=="no") echo "checked=\"checked\""; ?>/> 
	  no &nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 

	  <input name="ans1" type="radio" value="unsure" 
	 <?php if ($_GET["ans1"]=="unsure") echo "checked=\"checked\""; ?>/>unsure</p>

Is the form passed by GET? Sounds obvious, but the code works for me as long as I pass the values through the GET method.

Forgive my ignorance. I'm not sure what you mean. I've tried the form with both POST and GET.

Can you post the full form, please?

Thanks,

Oh wait, sorry, I read the question wrong. You want people to be able to navigate away from the page, then return and still have the form values?

You'd have to use sessions to hold the form values.

Check out this article.

Thanks,

On thing that could be a problem.

Do you want people to be able to navigate away *while* answering the form, without submitting it, and then return to find the answers as they left them?

If that is the case, you would have to look into JavaScript solutions.
PHP can only work with the data it is given, and you would actually have to submit the form to get the data to your PHP code.

Thank you for your responses. Could you give me a hint about what JavaScript I would need to use, or where I could find information on constructing it? I'm really not familiar with Java (and I'm pretty green at PHP, for that matter.) Thanks for helping.

I decided to simply have the links open in another window. Thank you both for your input.
