我目前正在为管理员面板开发基本的CRUD应用程序。 我正在尝试使用Bootstrap Modal，AJAX和PHP将数据添加到MySQL数据库。 这里的问题是我无法使用模态插入数据，甚至没有显示错误警报。我无法看到我所缺少的东西。谢谢。
以下是查看管理员的代码：
<?php
if(!isset($_SESSION['admin_email']))
{
echo "<script>window.open('login.php','_self')</script>";
}
else {
?>
<div class="row">
<div class="col-lg-12" >
<!-- FREO ADMINISTRATOR BREADCRUMB AND TITLE - START -->
<h1 class="page-header"><i class="fa fa-fw fa-trophy" ></i>Administrators</h1>
<ol class="breadcrumb" >
<li class="active" >
<i class="fa fa-dashboard" ></i> Dashboard > Administrators
</li>
</ol>
<!-- FREO ADMINISTRATOR BREADCRUMB AND TITLE - END -->
<!-- FREO ADMINISTRATOR SEARCH - START -->
<form class="form-search" action="" method="POST">
<div class="row">
<div class="col-md-1">
<h4><strong>SEARCH: </strong></h4>
</div>
<div class="col-md-7">

</div>
<div class="col-md-2">

以下是添加管理员的代码（AddAdministrator.php）：
<?php

$adminGender = $_POST['gender'];
$adminRole = $_POST['role'];
// DEFINE VARIABLES FOR DATA INSERTION - END
// BIND ALL VARIABLES FOR INSERTION - START
$preparedStatement = $dbConnection->prepare("INSERT INTO administrator
VALUES (?, ?, ?, ?, ? ,? ,? ,?)");
$preparedStatement->bind_param('ssssssss', $adminFName,
$adminLName,
$adminAddress,
$adminEmail,
$adminPassword,
$adminContact,
$adminGender,
$adminRole);
// BIND ALL VARIABLES FOR INSERTION - END
$preparedStatement->execute();
$countAdmin = $preparedStatement->affected_rows;
if($countAdmin == 1)
{
$adminResult.= '<label class="text-success">Freo Administrator Added</label>';
$preparedStatement = $dbConnection->prepare("SELECT *

$preparedStatement->execute();
$preparedStatement->bind_result($dsplyAdminId,
$dsplyAdminFName,
$dsplyAdminLName,
$dsplyAdminAddress,
$dsplyAdminEmail,
$dsplyAdminPassword,

$adminResult .= '<table class="table table-bordered table-hover table-striped">
