Re: radio buttons in $_POST

The radio button doesn't show up. Why is that and how can I have it show up? (the radio input does show up once one of the radios is checked, but I need it to show up when empty as well.)

One way would be to have a selection "None" and have it selected by default. As in, None <input type="radio" checked name="radio_test" value="None" /> Or you can just do something like, <?php if(!isset[$_POST['radio_test']))

    echo "radio_test = none\n";

foreach ($_POST as $key => $val) echo "$key = $val\n"; ?> Janet -- Janet Valade -- janet.valade.com
