Onchange提交，更新DB＆amp;显示结果代替下拉列表

Question

当调度程序选择更新数据库所需的驱

这是我到目前为止所不知道从哪里开始的。

$sql = "SELECT * FROM  dispatch WHERE driver = '' OR pu_time = '' OR do_time = ''";
    $result = mysql_query($sql);
            $i = 0;
        $color1 = "#ff0000";
        $color2 = "#00ff00";
        while($row = mysql_fetch_array($result)){

            if($i%2 == 1) {$color = $color1;}
                else {$color = $color2;}

                echo "<tr style='background-color: $color'>";
                echo '<td><input name="id" type="hidden" value="'.$row['id'].'" />'.$row['call_time'].'</td>';
                echo "<td>".$row['start_address']."</td>";
                echo "<td>".$row['end_address']."</td>";
                echo "<td>".$row['phone']."</td>";
                echo "<td>".$row['puat']."</td>";

                    if (isset($row['driver']) === true && empty($row['driver']) === true){

                        echo '<td>
                             <form id = "driver">
                              <select name="driver">
                              <option value="Mike">Mike</option>
                              <option value="Cheek">Cheek</option>
                              <option value="Spencer">Spencer</option>
                              <option value="Melissa">Melissa</option>
                            </select>
                            </form></td>';

                        }
                        else {
                            echo "<td>".$row['driver']."</td>";
                            }

                echo "</tr>";
                $i++;
        }
    }

我想出了一个非常粗糙的工作......如果有人有更好的想法，我愿意接受它！

$sql = "SELECT * FROM  dispatch WHERE driver = '' OR pu_time = '' OR do_time = ''";
    $result = mysql_query($sql);
            $i = 0;
        $color1 = "#ff0000";
        $color2 = "#00ff00";
        while($row = mysql_fetch_array($result)){

            if($i%2 == 1) {$color = $color1;}
                else {$color = $color2;}

                echo "<tr style='background-color: $color'>";
                echo '<td><input name="id" type="hidden" value="'.$row['id'].'" />'.$row['call_time'].'</td>';
                echo "<td>".$row['start_address']."</td>";
                echo "<td>".$row['end_address']."</td>";
                echo "<td>".$row['phone']."</td>";
                echo "<td>".$row['puat']."</td>";

                    if (isset($row['driver']) === true && empty($row['driver']) === true){

                        echo '<td>
                             <form id = "driver">
                              <select name="driver" onchange="this.form.submit()">
                              <option value="Mike">Mike</option>
                              <option value="Cheek">Cheek</option>
                              <option value="Spencer">Spencer</option>
                              <option value="Melissa">Melissa</option>
                            </select>
                            </form></td>';
                                if (isset($_GET['driver'])){
                                    $new_driver = $_GET['driver'];
                                    $id = $row['id'];
                                    $update_d = "UPDATE dispatch SET driver = '$new_driver' WHERE id = '$id'";
                                    mysql_query($update_d,$con)
                                    or die;
                                    unset($_GET['driver']);
                                    echo '<script type="text/JavaScript">
                                            window.location.href = "new_index.php";
                                          </script>';
                                    }
                        }
                        else {

                            echo $_GET['driver']."Hello";
                            echo "<td>".$row['driver']."</td>";
                            }



                echo "</tr>";
                $i++;
        }
    }
