PDO不在数据库中插入数据

Question

我正在尝试使用PDO和OOP创建注册页面。 我花了3个小时，但是找不到我的代码有什么问题。一切工作正常（我已经调试了），但是数据没有插入数据库中。

Db1.php

<?php
class Db1
{
    private $host = "localhost";
    private $user = "root";
    private $db = "website";
    private $pass = "";
    public $conn ;

    public function __construct()
    {
        $this->conn = new PDO("mysql:host=".$this->host.";dbname=".$this->db,$this->user,$this->pass);
    }
    public function getconn()
    {
        return $this->conn;
    }
}
?>

users.php

<?php
include_once("Db1.php");
class users extends Db1
{
    private $id;
    private $name;
    private $email;
    private $password;
    private $member_since;
    private $last_seen;
    private $country;
    private $city;
    private $reputation;
    private $status;

    public function insertData($name,$email,$password,$country="",$city="")
    {
         $sql = "INSERT INTO users (name,email,password,member_since,last_seen,country,points,city,status) VALUES (name=:name,email=:email,password=:password,member_since=:member_since,last_seen=:last_seen,country=:country,reputation=:reputation,city=:city,status=:status";
        // i have tried this also.
        //$sql = "INSERT INTO users SET name=:name,email=:email,password=:password,country=:country,city=:city,reputation=:reputation,member_since=:member_since,last_seen=:last_seen,status=:status";
        $q = parent::getconn()->prepare($sql);
        $q->execute(array(':name'=>$name,':email'=>$email,':password'=>$password,':country'=>$country,':city'=>$city,':reputation'=>3,':member_since'=>date("y-m-d h:i:s"),':last_seen'=>date("y-m-d h:i:s"),':status'=>'a'));
        return true;
    }

}
?>

signup.php

<?php
if(isset($_POST['signup'])){

    include_once("classes/users.php");
    $obj = new users;

    if($obj->insertData($_POST['name'],$_POST['email'],$_POST['password'])){
        echo"data inserted!";
    }
}
?>

请尝试此操作。.您的查询中缺少右圆括号

<?php
include_once("Db1.php");
class users extends Db1
{
    private $id;
    private $name;
    private $email;
    private $password;
    private $member_since;
    private $last_seen;
    private $country;
    private $city;
    private $reputation;
    private $status;

    public function insertData($name,$email,$password,$country="",$city="")
    {
         $sql = "INSERT INTO users (name,email,password,member_since,last_seen,country,points,city,status) VALUES (:name,:email,:password,:member_since,:last_seen,:country,:reputation,:city,:status)";


        $q = parent::getconn()->prepare($sql);
        $q->execute(array(':name'=>$name,':email'=>$email,':password'=>$password,':country'=>$country,':city'=>$city,':reputation'=>3,':member_since'=>date("y-m-d h:i:s"),':last_seen'=>date("y-m-d h:i:s"),':status'=>'a'));
        return true;
    }

}
?>

您错过了PHP.NET的prepare语句：

$sql = "INSERT INTO REGISTRY (name, value) VALUES (:name, :value)";

但是你尝试做

$sql = "... VALUES (name=:name,email=:email,password=:password,member_since=:member_since,last_seen=:last_seen,country=:country,reputation=:reputation,city=:city,status=:status";

而且您错过了右括号^^
