Detect radio buttons pressed in php


Here is one way of detecting a radio button has been pressed using php. So for this example we have three radio buttons on the form.

<form id="form1" name="form1" method="post" action="">
        <label>
            <input name="radiobutton" type="radio" value="option 1" onchange="this.form.submit();"/>
            canteen
        </label>
    <p>
        <label>
            <input name="radiobutton" type="radio" value="option 2" onchange="this.form.submit();" />
            quarters
        </label>
    </p>
    <p>
        <label>
            <input name="radiobutton" type="radio" value="option 3" onchange="this.form.submit();"/>
            server room
        </label>
    </p>
</form>

The php...

<?php
if ($_POST['radiobutton'] == 'option 1') {
    echo 'option 1 radio button pressed';
}
?>
