我创建了一个表来显示员工的详细信息。以下是表格页面中使用的代码部分
echo "<td> <a href='#edit' data-toggle='modal'> edit </a> </td>";
执行此页面后收到的视图将是这样的
ID Name Edit
1 emp1 edit
2 emp2 edit
模态代码
<div class = "modal fade" id="edit" role="dialog">
<div class = "modal-dialog">
<div class = "modal-content">
<div class = "modal-header">
<h4> Edit </h4>
</div>
<div class="modal-body">
<form role="form" action="edit_emp.php" method="post">
<div class="form-group">
<label for="exampleInputEmail1">Name</label>
<input type="text" class="form-control" id="exampleInputEmail1" placeholder="" name="empname">
</div>
<input name="submit" type="submit" value=" Edit ">
</form>
</div>
<div class="modal-footer">
<a class="btn btn-primary" data-dismiss="modal"> Close </a>
</div>
</div>
</div>
</div>
edit_emp.php页面中使用的代码是
<?php
$con=mysqli_connect("localhost","root","","employee");
// Check connection
if (mysqli_connect_errno()) {
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
$id = $_POST['id'];
$empname=$_POST['empname'];
mysqli_query($con,"UPDATE employee SET empname='$empname' WHERE id='".$id."'");
mysqli_close($con);
header("Location: index.php");
?>
我希望当模式弹出时,用户可以输入新值,并更新该特定行的值。问题是它只是运行代码而不显示任何结果。有人可以告诉我如何获得理想的结果。

mysqli_query($con,"UPDATE employee SET empname='$empname' WHERE id='".$id."'");
替换为
$result= mysqli_query($con,"UPDATE employee SET empname=$empname WHERE id='$id'");
if ($result===false ) {
printf("error: %s\n", mysqli_error($con));
}

在表单中添加此行
<label for="exampleInputEmail1">ID</label>
<input type="text" class="form-control" id="exampleInputEmail1" placeholder="" name="id">
