I have an HTML form with radio buttons in a loop with same name like this:

Post Id 1:<input type="radio" name="radiob[]" id="radio" value="Yes" />
Post Id 2:<input type="radio" name="radiob[]" id="radio" value="Yes" />

I want to save radio button selected post into database but I want the user to select only one post. When I put post id with radio button name like radiob[2], the user can select multiple radio buttons so how can the user only check one radio button and the form send both the radio button id and value?

Thanks.

    You do know that duplicate id values violates the specs, right? Commented Dec 16, 2010 at 16:52

Use the ID as value, and you don't need to use radiob[] because only one value will be transmitted to the server anyway.

Post Id 1:<input type="radio" name="radiob" value="1" />
Post Id 2:<input type="radio" name="radiob" value="2" />

Sending the same value for a bunch of radios makes no sense - it's missing the point of having a radio. This is a much better way.
what i am trying to do is saving in db that this selected this post so in post id feild i save post id and in text feild i save yes
@livetolearn: Well I don't know the overall structure of your form. Maybe you should post it and precisely explain how it works.

IDs should not be the same for 2 elements and the values should represent be what you need to store anyway:

<label for="radio_1">Post Id 1</label>:<input type="radio" name="radiob" id="radio_1" value="1" />
<label for="radio_2">Post Id 2</label>:<input type="radio" name="radiob" id="radio_2" value="2" />

You would then pick up the variables in php using either the get or post array (depending upon your submission method:

$value = $_POST['radiob']; // or $_GET['radiob']
