How do I display radio button results?

[Bob Sanderson]

I have a form which uses several radio buttons to enter data. It works fine
as far as entering goes, but I can't figure out how to display which button
is checked when I view the record. I could do a if-then routine but it
seems like there should be an easier way.

Any help will be greatly appreciated.

What's your HTML like and how are you dealing with it in PHP?

This (with possible unintended errors corrected) works:

<!-- HTML, assume correct DOCTYPE, ... -->
<form ...>
<div class="group1">
<label><input type="radio" name="r[0]" value="0" checked>none</label>
<label><input type="radio" name="r[0]" value="1">one</label>
<label><input type="radio" name="r[0]" value="1">two</label>
</div>
<div class="group2">
<label><input type="radio" name="r[1]" value="0" checked>none</label>
<label><input type="radio" name="r[1]" value="1">one</label>
<label><input type="radio" name="r[1]" value="1">two</label>
</div>
<!-- some submit button -->
</form>

And the PHP that deals with it could be

<?php
foreach ($_POST['r'] as $k=>$radio) {
echo 'For group ', $k, ', you selected the option with ',
$radio, " for its value.<br>\n";
}
?>
