php - 使用消息“object(PDO)#1 (0)”连接到 Mysql 数据库时出错
问题描述
我有点缺乏经验，我试图创建一个带有 php 和 DOP 连接的小型预订表单，但我总是收到 prepar () 属性的错误。连接上 var_dump () 的 esegundo 我已经看到它返回了这个答案......帮您一把，我告诉您我已经取消标记 php.ini 文件中的 PDO 扩展名并且我使用了 LAMP 堆栈在 Ubuntu 机器上。我不知道如何移动，能否有好人帮助我了解我错在哪里并让我找到解决方案并让我了解我的错误在哪里？
为了清楚起见，放置我的代码，并感谢任何想要登录的人
代码：
<?php
try{
/*Connection file db.php */
$dsn = "mysql:host=localhost;dbName=lamp";
$conn = new PDO($dsn, "root", "StraMa87");
$conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
echo "connessione avvenuta con successo";
}catch(PDOException $e){
$e->getMessage();
}
?>
这是管理预订的类文件：
<?php
/**
* Booking
*/
class Booking
{
public $db;
function __construct($db)
{
var_dump($db);
$this->db = $db;
}
public function booking_table($post){
$nome = trim($post["nome"]);
$email = filter_var( filter_var( trim( $post["email"] ), FILTER_SANITIZE_EMAIL), FILTER_VALIDATE_EMAIL );
$tel = trim( $post["tel"] );
$intolleranze = trim($post["intolleranza"]);
$data = trim($post["date"]);
$hour = trim($post["hour"]);
/* Query */
$q = "INSERT INTO booking (nome,telefono,email,intolleranze,data_prenotazione,hour) VALUES ('$nome', '$tel', '$email', '$intolleranze', '$data', '$hour')";
try {
$rq = $this->db->prepare($q, array(PDO::ATTR_CURSOR => PDO::CURSOR_FWDONLY));
$rq->bindParam(':nome', $nome, PDO::PARAM_STR);
$rq->bindParam(':tel', $tel, PDO::PARAM_STR);
$rq->bindParam(':email', $email, PDO::PARAM_STR);
$rq->bindParam(':intolleranze', $intolleranze, PDO::PARAM_STR);
$rq->bindParam(':data', $data, PDO::PARAM_STR);
$rq->bindParam(':hour', $hour, PDO::PARAM_STR);
$rq->execute();
} catch (PDOException $e) {
$e->getMessage();
}
}
}
这是必须发送数据的表格（html不是我做的，因为我的目的是在php和后端练习）：
<?php
require_once('./booking/db.php');
require_once('./booking/booking.php');
ini_set('display_error', 1);
ini_set('display_startup_errors', 1);
error_reporting(E_ALL);
$booking = new Booking($conn);
if( $_POST ){
$booking->booking_table($_POST);
}
?>
