所以基本上我有一份员工基本信息表。它已经具有从mysql数据库中检索的值。 employee basic information table。正如您在桌面上看到的那样，它右上角有一个编辑按钮。单击后，将显示模态对话框。 edit basic information modal
我的问题是，一旦用户填写了编辑表单上的字段并点击了保存按钮，我就不知道如何更新基本信息表上的记录。
我想要发生的是当用户点击模态对话框上的保存按钮时，它会自动将表格上的现有数据更改为更新的数据，无需重新加载页面。
所以意思是，它需要一个ajax或jquery来更新网页的各个部分 - 无需重新加载整个页面，我不知道它是如何工作的。
这是我的表格代码：
<br>
<button type="button" class="btn btn-info btn-sm pull-right" data-toggle="modal" data-target="#myModal1">Edit</button>
<div class="clear text-primary bold"><i class="fa fa-user text-primary"></i> Basic Information </div>
<br>
<section class="padder-v">
<table class="table table-responsive">
<tbody>
<tr>
<th>
<strong> Employee ID</strong>
</th>
<td>
<p class="text-muted"><?php echo $_SESSION['emp_code']; ?></p>
</td>
<th>
<strong> Birthdate</strong>
</th>
<td>
<p class="text-muted"><?php echo $_SESSION['birthdate']; ?></p>
</td>
</tr>
<tr>
<th>
<strong> Last Name</strong>
</th>
<td>
<p class="text-muted"><?php echo $_SESSION['lname']; ?></p>
</td>
<th>
<strong> Gender</strong>

<p class="text-muted"><?php echo $_SESSION['gender']; ?></p>
</td>

<tr>

<p class="text-muted"><?php echo $_SESSION['fname']; ?></p>

<p class="text-muted"><?php echo $_SESSION['active']; ?></p>
</td>
</tr>
</tbody>
</table>

答案 0 :(得分：1)
从模态发布数据时找不到$emp_code。您的查询将失败，因为没有$emp_code值WHERE emp_id = '$emp_code'
因此，您需要添加值为<?php echo $_SESSION['emp_code']; ?>的隐藏输入，并将其与其他表单值一起发布，因为在PHP文件中。
以模式形式添加
<input type="hidden" class="form-control" id="emp_code" name="emp_code" value ="<?php echo $_SESSION['emp_code']; ?>" >
在PHP文件中添加
$emp_code = $_POST['emp_code'];
<强>更新
另一个问题出在您的查询中， emp_maritalstatus = '$maritalstatus', 之后还有一个额外的逗号，因此更新时会出错。
我有更新查询
$query = $mysqli->query("UPDATE tbl_employee SET emp_fname = '$firstname',
emp_mname = '$middlename',
emp_lname = '$lastname',
emp_bday = '$birthdate',
emp_gender = '$gender',
emp_maritalstatus = '$maritalstatus'
WHERE emp_id = '$emp_code'");
