【问题描述】：
我可以在数据库中建立连接，我可以制作表格，但我不能在该表格中插入任何值， 我的代码是：
<?php
if (!file_exists('config.php')) {
header('Location: install.php?page=introduction');
}
error_reporting(E_ALL);
ini_set('display_errors', '1');
echo enqueue_style('install', GET_URI_DIRECTORY . '/includes/css/install.css', '1.0');
echo enqueue_style('bootstrap', GET_URI_DIRECTORY . '/includes/css/bootstrap.min.css', '3.3.7');
echo enqueue_style('merriwheather-font', GET_URI_DIRECTORY . '/includes/css/font/merriwheather.css');
?>
<div class="container install-container">
<div class="panel-group">
<div class="panel panel-primary">
<div class="panel-heading">CONFIGURATION</div>
<div class="panel-body">
Here you need to submit some information related to your login and site
<form method="post" class="form-horizontal">
<div class="form-group">
<label class="control-label col-sm-2" for="fname">First Name</label>
<div class="col-sm-10">
<input type="text" name="fname" class="form-control" id="fname" placeholder="First Name">
</div>
</div>
<div class="form-group">
<label class="control-label col-sm-2" for="lname">Last Name</label>
<div class="col-sm-10">
<input type="text" name="lname" class="form-control" id="lname" placeholder="Last Name">
</div>
</div>
<div class="form-group">
<label class="control-label col-sm-2" for="uname">User Name</label>
<div class="col-sm-10">
<input type="text" name="uname" class="form-control" id="uname" placeholder="User Name for login">
</div>
</div>
<div class="form-group">
<label class="control-label col-sm-2" for="pwd">Password</label>
<div class="col-sm-10">
<input type="text" name="pwd" class="form-control" id="pwd" placeholder="Password for login">
</div>
</div>
<div class="form-group">
<label class="control-label col-sm-2" for="sname">Site Name</label>
<div class="col-sm-10">
<input type="text" name="sname" class="form-control" id="sname" placeholder="Site Name">
</div>
</div>
<button type="submit" class="btn btn-primary btn-block">Submit</button>
<b>Note:-</b> <small>This will create your first admin account</small>
</form>
</div>
</div>
</div>
</div>
<?php
if (isset($_POST['fname'])) {
$firstname = $_POST['fname'];
}
if (isset($_POST['lname'])) {
$lastname = $_POST['lname'];
}
if (isset($_POST['uname'])) {
$username = $_POST['uname'];
}
if (isset($_POST['pwd'])) {
$password = password_hash($_POST['pwd'], PASSWORD_DEFAULT);
}
$capability = 'admin';
if (isset($_POST['sname'])) {
$sitename = $_POST['sname'];
}
if (isset($_POST['fname']) && isset($_POST['lname']) && isset($_POST['uname']) && isset($_POST['pwd']) && isset($_POST['sname'])) {
if (execute_table_making_sql() === true) {
function configure_admin_login() {
global $dbconn, $table_prefix, $firstname, $lastname, $username, $password, $capability;
$firstname = mysqli_real_escape_string($firstname);
$lastname = mysqli_real_escape_string($lastname);
$username = mysqli_real_escape_string($username);
$password = mysqli_real_escape_string($password);
$capability = mysqli_real_escape_string($capability);
$query = "INSERT INTO '{$table_prefix}'users (`FirstName`, `LastName`, `Capability`, `UserName`, `Password`) VALUES ('{$firstname}', '{$lastname}', '{$capability}', '{$username}', '{$password}')";
if ($dbconn->query($query) === true) {
return true;
}
$dbconn->error;
}
configure_admin_login();
}
}
echo enqueue_script('bootstrap', GET_URI_DIRECTORY . '/includes/js/bootstrap.min.js', '3.3.7');
echo enqueue_script('jquery', GET_URI_DIRECTORY . '/includes/js/jquery-3.1.1.min.js', '3.1.1');
echo enqueue_script('smoothscroll', GET_URI_DIRECTORY . '/includes/js/smoothscroll.js', '1.2.1');
制作表格的代码是：
if (file_exists('config.php')) {
$dbconn = database::dbconn($host, $username, $password, $database);
if ($dbconn !== false) {
function execute_table_making_sql() {
global $dbconn, $table_prefix;
$sql = 'CREATE TABLE '.$table_prefix.'users (
FirstName varchar(50) NOT NULL,
LastName varchar(50) NOT NULL,
Capability varchar(20) DEFAULT "member" NOT NULL,
UserName varchar(75) NOT NULL,
Password varchar(100) NOT NULL
)';
if($dbconn->query($sql) === true) {
return true;
}
}
}
}
class database {
static function dbconn($host, $user, $pass, $db) {
$connection = new mysqli($host, $user, $pass, $db);
if ($connection->connect_error) {
echo "Connection failed: " . $connection->connect_error;
return false;
}
return $connection;
}
}
我可以在这里制作表格，所以我的数据库连接是真实的，但我不能在我的表格中插入任何值。我的代码有什么问题请告诉我。帮我调试这段代码。提前致谢！
注意： 我做的一些常量不是错误的，使用前检查成功
