Question

当我在获取数组中使用更新模式时，发生了一些奇怪的情况，这是我的代码，用于使用php数组生成表：

while($row = mysqli_fetch_array($tablequery)) {
if ($id != -1 && $id != $row['Date']) {
    echo '</tbody>';
    echo '</table>';
}

if ($id != $row['Date']) {
    echo '<div class="container omhdatebreak"><i class="material-icons floatleft">today</i><div>'.date("d/m/Y", strtotime($row['Date'])).' - '.date("l",strtotime($row['Date'])).'</div></div>
        <table class="table omhtablebreak"> 
            <thead>
         <tr>
            <th class="table-header" width="5%"></th> 
            <th class="table-header" width="10%"></th>   
            <th class="table-header" width="30%">Time</th>
            <th class="table-header" width="30%"> Customer </th>
            <th class="table-header" width="25%" colspan="2"></th>
          </tr>
    </thead>';

    $id = $row['Date'];
}?>

    <tbody>     
        <tr class="table-row" id="row-<?php echo $row["LineRef"]; ?>">
            <?php $ColChange = $row["Status"];
if ($ColChange == "New") {
    echo '<td class="table-row "><i class="material-icons" style="width:10px; color:#109aee;" title="New Appointment"> notifications</i></td>';
} else {
    echo '<td class="table-row"><i class="material-icons" style="width:10px; color:#328132;" title="Completed Appointment"> check_circle</i></td>';
}?>
            <td class="table-row"><?php echo $row["Status"]; ?></td>
            <td class="table-row"><?php echo $row["StartTime"]; ?> - <?php echo $row["EndTime"]; ?></td>
            <td class="table-row"><?php echo $row["Firstname"]; ?></td>
            <!-- action -->

                    <div class="form-group">
                        <label class="CustomLabel">Appointment Information</label>  
                 <textarea name="notesupdate" id="notes<?php echo $row["LineRef"]; ?>" class="form-control"><?php echo $row["Notes"]; ?></textarea>  
                 </div>

                      <div class="center">
                        <input type="radio" id="status1" name="statusupdate" value="New" checked>
                        <label for="contactChoice1">New</label>

                        <input type="radio" id="status3" name="status" value="In Progress">
                        <label for="contactChoice3">In Progress</label>

                        <input type="radio" id="status4"name="status" value="Completed">
                        <label for="contactChoice3">Completed</label>                            
                    </div>
                        <button type="submit" onclick="updateModal(<?php echo $row["LineRef"]; ?>)" class="btn btn-success omhformsubmit floatleft"><i class="material-icons floatleft">add_circle</i><div>update Appointment</div> 
</button>

        </div>
                <div class="modal-footer">

                 </div>
        </div>
    </div>

</div>
             </td>
        </tr>
    </tbody>

在更新约会按钮上，有一个正在调用的函数，如下所示：

    function updateModal(str){
        var id = str;
        var name = $('#fname'+str).val();         
        $.ajax({
            type: "POST",
            url: "update.php",
            data: {name:name, lineref:id},
            success:function(data){  
                       window.alert("Appointment has been Updated");
                    }  
        });
    }

因此，当更新成功时，我希望在屏幕上看到一个警报，但是当我单击“更新”按钮时，警报不会出现，但是如果我回头查看MYSQL中的表，则该行已更新与新的信息。我的update.php文件如下所示：

<?php
$connection = mysqli_connect($dbhost, $dbuser, $dbpass, $dbname);


if (mysqli_connect_errno()) {
die("Database connection failed: " . mysqli_connect_error() . " (" . 
mysqli_connect_errno() . ")"
);
 }

$fname = $_POST['name'];
$OMHid = $_POST['lineref'];


$updatequery  =   "UPDATE appointments SET Firstname = '$fname' Where LineRef = $OMHid";

    $result = mysqli_query($connection, $updatequery);

mysqli_close($connection);

有人会知道是什么会导致该功能无法成功显示警报吗？
