Question

我正在使用此类代码向数据库中插入数据：

<?php

Class User
{
  private $error = "";
  public  function signup($post)
  {
    $data = array();

    $data['name']    = trim($_POST['name']);
    $data['email']   = trim($_POST['email']);
    $data['pass']    = trim($_POST['pass']);
    $pass2           = trim($_POST['pass2']);

    if(empty($data['email']) || !preg_match("/^[0-9a-zA-Z_-]+@[0-9a-zA-Z_-]+.[0-9a-zA-Z_-]+$/", $data['email']))
    {
      $this->error .= "Please enter a valid Email <br>";
    }
    if(empty($data['name']) || !preg_match("/^[a-zA-Z]+$/", $data['name']))
    {
      $this->error .= "Please enter a valid Name <br>";
    }

    if($data['pass'] !== $pass2)
    {
      $this->error .= "Password dont match <br>";
    }

    if(strlen($data['pass']) < 4)
    {
      $this->error .= "Password must be at least 4 character long <br>";
    }

    if($this->error == "")
    {
      $data['rank'] = "customer";
      $data['url_address'] = $this->get_random_string_max(60);
      $data['date'] = date("Y-m-d H:i:s");

      $query  = "INSERT INTO users (url_address, name, email, pass, date, rank) VALUES (:url_address, :name, :email, :pass, :date, :rank)";
      $db     = Database::getInstance();
      $result = $db->write($query, $data);

      if ($result) {
        header("Location:" . ROOT . "login");
        die();
      }
    }
  }

  private function get_random_string_max($length)
  {
    $array = array(0,1,2,3,4,5,6,7,8,9,'a','b','c','d','e','f','g','h','i','j','k','l','m','n','o','p','q','r','s','t','u','v','w','x','y','z');
    $text = "";

    $length = rand(4, $length);
    for ($i=0; $i>$length;$i++) {
      $random = rand(0, 61);
      $text .= $array[$random];
    }
    return $text;
  }
}

这是数据库类：

<?php

Class Database
{
  public static $con;
  public function __construct()
  {
    $dsn = 'mysql:hostname=localhost;dbname='. DB_NAME;
    $options = array(
      PDO::ATTR_PERSISTENT => true,
      PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION
    );

    try {
      return $db = new PDO($dsn, DB_USER, DB_PASS, $options);
    } catch (PDOException $e) {
      die($e->getMessage());
    }
  }

  public static function getInstance()
  {
    if(self::$con) {
      return self::$con;
    }
    return $instance = new self();
  }

  public function read($query, $data = array())
  {
    $stmt = self::$con->prepare($query);
    $result = $stmt->excute($data);
    if ($result) {
      $data = $stmt->fetchAll(PDO::FETCH_OBJ);
      if(is_array($data)) {
        return $data;
      }
    }
    return false;
  }

  public function write($query, $data = array())
  {
    $stmt = self::$con->prepare($query);
    $result = $stmt->excute($data);
    if ($result) {
      return true;
    }
    return false;
  }
}

我正在使用 MVC，这是注册控制器页面和数据库类。

pass2 是在表单中重新输入的密码。

但是数据没有插入到数据库中，也没有重定向到登录页面。

和 PDO::ERRMODE_EXCEPTION

没有显示任何错误。

有什么问题？

在数据库类中，您在行中编写函数 excute() 时出错：

$result = $stmt->excute($data);

应该是execute()

$result = $stmt->execute($data);

语句未插入数据库
