So zeigen Sie den Wert eines Optionsfelds mit PHP an

Zunächst einmal sollte Ihr Formular in etwa so aussehen:

<form action="page_you_want_to_display.php" method="POST">

    <label for="type">Job Type:</label>

    <label for="fulltime">
        <input class="radio_style" id="fulltime" name="job_type" type="radio" value="fulltime">
        Fulltime
    </label>

    <label for="parttime">
        <input class="radio_style" id="parttime" name="job_type" type="radio" value="parttime">
        Part Time
    </label>

    <input name="submitted" type="submit" value="Submit">

</form>

Die Seite, auf der Sie anzeigen möchten, sollte in etwa so aussehen:

if(isset($_POST["submitted"])){

    $job_type = $_POST['job_type'];

    echo '<div class="job_type_div">';

        if($job_type=='fulltime'){

            $res = mysql_query("SELECT * FROM jobs WHERE job_type='fulltime'");

            while ($row = mysql_fetch_assoc($res)) {

                echo '<div class="fulltime">';

                    echo $row['job_title'].' - '.$row['job_type'];

                echo '</div>';

                echo '<br>';

            }

        } elseif ($job_type=='parttime'){

            $res = mysql_query("SELECT * FROM jobs WHERE  job_type='parttime'");

            while ($row = mysql_fetch_assoc($res)) {

                echo '<div class="parttime">';

                    echo $row['job_title'].' - '.$row['job_type'];

                echo '</div>';

                echo '<br>';

            }               

        }

echo '</div>';

}

und CSS:

.fulltime {
    margin:0px;
    padding:5px;
    width:300px;
    background:#9C0;
    color:#fff;
}   
.parttime {
    margin:0px;
    padding:5px;
    width:300px;
    background:#069;
    color:#fff;
}
