这是我要完成的工作流程。

在我的 Users.html 页面加载时，我执行 php 代码以从 mysql 数据库中获取数据，然后使用 php 创建一个动态表以循环并为每行创建表行和数据元素。

每行都有一个删除按钮；按下删除按钮后，我打开一个 jQuery UI 模态对话框，其中传入并显示在对话框中的用户数据。

如果用户点击确认删除用户，我使用 $.post 打开一个 php 页面并传递 php 页面的数据以执行用户删除。

成功选择（或错误）后，我使用标题“users.html?error=x”，其中 x 是错误号，因此用户返回到他们开始的原始 users.html 页面。

问题是 users.html 页面永远不会被刷新（并且页面在整个 modal-php 重定向过程中实际上从未改变。

我使用 (#divIDx).remove() 删除表中的条目，但由于它是动态表，当用户更改表上的页面或选择或选择允许每页更多或更少的条目时，用户即使它们已从数据库中删除，也会返回。由于用户点击确认删除按钮，我尝试调用 document.location.reload()，但我的安全人员听到了该调用并终止了当前会话。

因此，要将其分解为 HTML 锚点，请单击 -> jquery 对话框 -> 删除用户 php -> 回到相同的 users.html 但 users.html 从不刷新。

这是执行数据库查询的 users.html

<?php
    require_once( '_/connections/login.php' );

    $stmt = $mysqli_login->stmt_init();
    //$businessid =  $mysqli_login->real_escape_string($orgid);
    $stmt = $mysqli_login->prepare("SELECT firstname, lastname, role, email, id, organizationid FROM login where organizationid = " . $mysqli_login->real_escape_string($orgid) );
    //$stmt = $mysqli_login->prepare("SELECT firstname, lastname, role, email, id, organizationid FROM login where organizationid = ?");
    if(!isset($stmt)){}else{
        ///////////////////////////////////////////////////////////
        //TODO: find out why bind_params is not working here
        ///////////////////////////////////////////////////////////
        //$stmt->bind_params('s', $businessid);
        $stmt->execute(); // Execute the prepared query.
        $stmt->store_result();
    $stmt->bind_result($Ufirstname, $Ulastname, $Urole, $Uemail, $Uid, $Uorgid);
    }
?>

然后我使用这段代码创建我的表

<?php if(!$stmt){echo $users_found = 0;} else {$users_found = $stmt->num_rows;}?>

        <div class="widget">
            <div class="whead">
                <h6>Registered Dashboard Users: 
                    <?php echo $users_found; ?>&nbsp;&nbsp;
                    <?php if(isset($_GET['del_error'])){
                        switch($_GET['del_error']) {
                        case '0':
                            echo "User Deleted";
                            break;
                        case '1':
                            echo "Error deleting user";
                            break;
                        case '2':
                            echo "Error deleting user";
                            break;
                        case '3':
                            echo "Error deleting user";
                            break;
                        default:

                            break;
                        }
                    }?>
                </h6>

                    </tbody>
                </table> 
                </div>
            </div>
        </div>

表单 div 很简单，因为我从另一个 HTML 页面动态注入 HTML

<div id="dialog_edituser" title="Edit User Form">
    <a id="dialog_edituser_content"></a>
</div>

对话框的 javscript 代码获取必要参数的值，将它们存储在一些全局变量中，然后在打开时，HTML 的内容被注入到适当的 div 中，服务器已经使用一些填充了所需的动态数据回显 $_POST['...'] 命令

    buttons: {
            "Submit": function() {
                //remove the data from the table
                $('#'+dialog_deluser_divid).remove();
                //remove the user from the database
                $.post("_/processUserRemove.php", {

});
//===== End Remove User Dialog Box =====//

一旦用户点击提交按钮，值就会发布到 processUserRemove.php 并且 processUserRemove.php 将执行 header('Location: ../users.html?del_error=x'); 其中“x”是相应的错误号。

这是 processUserRemove.php 代码

<?php
require_once( './connections/login.php' );
require_once( 'login_functions.php' );
sec_session_start(); // Our custom secure way of starting a php session. 

if(isset($_POST['fname'], $_POST['lname'], $_POST['email'], $_POST['role'], $_POST['id'],             $_POST['orgid'])) {
//////////////////////////////////////////////////////////////////////
//TODO: get the associated business ID from the current user
//////////////////////////////////////////////////////////////////////
$RUfirstname = $_POST['fname'];
$RUlastname = $_POST['lname'];
$RUemail = $_POST['email'];
$RUrole = $_POST['role'];
$RUid = $_POST['id'];
$RUorgid = $_POST['orgid'];
$RU_currentuser_orgid = $_SESSION['organizationid'];
$del_stmt = $mysqli_login->init();
if ($RU_currentuser_orgid == $RUorgid) {
    if ($del_stmt = $mysqli_login->prepare("DELETE FROM login WHERE firstname = ? and lastname = ? and email = ? and role = ? and organizationid = ? and id = ?")) {    
       $del_stmt->bind_param('ssssss', $RUfirstname, $RUlastname, $RUemail, $RUrole, $RUorgid, $RUid); 
       // Execute the prepared query.
       $del_stmt->execute();
       header('Location: ../index.html'); 
    } else {
        // Registration Failed
        header('Location: ../users.html?del_error=1');
    }
} else {
  //  orgainization id's don't match
  header("Location: ../users.html?del_error=2_firstname=" . $RUfirstname . "_lastname=" . $RUlastname  . 
        "_email=" . $RUemail . "_role=" . $RUrole . "_organizationid=" . $RUorgid . "_id=" . $RUid . "_cuid=" . $RU_currentuser_orgid); 
}
} else { 
// The correct POST variables were not sent to this page.
header('Location: ../users.html?del_error=3'); 
}
?>

但是在button -> modal -> php -> users.html的整个过程中，users.html页面从不刷新。删除表格条目是可行的，但是当用户与表格交互时，删除的数据又回来了，并且 document.location.reload(true) 将我从系统中注销？！？

对不起所有的代码，但我想非常清楚我是如何遗漏了什么，或者我做了多么复杂的操作，这应该是一个简单的操作。

非常感谢任何帮助，谢谢。
