我正在使用opencart 3浏览器关闭客户注销，如何停止客户注销甚至浏览器关闭

Question

我正在使用opencart 3，我的问题是，当客户关闭浏览器，再次打开客户是注销时，我想改变这种行为，当客户一旦登录时，他/她不应该退出，直到他/她单击注销按钮，即使他/她关闭浏览器，并再次打开，他/她应该保持登录。

您必须在OpenCart中修改3个文件才能完成这一任务。

/catalog/controller/account/login.php

在登录过程中，您必须将客户ID和电子邮件存储在cookie中。有必要把它们储存起来。电子邮件是不够的，因为您必须检查存储的客户ID是否属于存储的电子邮件。

  public function index() {
    [...]
    if (($this->request->server['REQUEST_METHOD'] == 'POST') && $this->validate()) {
      // Unset guest
      unset($this->session->data['guest']);

      // store customer ID and email encrypted
      $my_customer_id = $this->customer->getId();
      $my_customer_id_crypted = $this->encrypt($my_customer_id, "your_key_for_customer_id_encryption");

      $my_email = $this->request->post['email'];
      $my_email_crypted = $this->encrypt($this->request->post['email'], "your_key_for_email_encryption");

      setcookie("MyCustomerID", $my_customer_id_crypted , time() + (365 * 24 * 60 * 60) , "/");
      setcookie("MyEmail", $my_email_crypted , time() + (365 * 24 * 60 * 60) , "/");
      [...]
    }
    [...]
  }

  [...]

  // https://www.phpcluster.com/simple-two-way-encryption-in-php/
  // you can use other encryption if you want, just an example
  protected function encrypt($plainText, $key) {
    $secretKey = md5($key);
    $iv = substr( hash( 'sha256', "aaaabbbbcccccddddeweee" ), 0, 16 );
    $encryptedText = openssl_encrypt($plainText, 'AES-128-CBC', $secretKey, OPENSSL_RAW_DATA, $iv);
    return base64_encode($encryptedText);
  }

/catalog/controller/account/logout.php

在注销过程中，您必须删除客户ID和电子邮件cookie。

  public function index() {
    if ($this->customer->isLogged()) {
      $this->customer->logout();

      // delete cookies
      unset($_COOKIE['MyCustomerID']);
      unset($_COOKIE['MyEmail']);

      setcookie("MyCustomerID", "", 0, "/");
      setcookie("MyEmail", "", 0, "/");
      [...]
    }
    [...]
  }

/catalog/controller/common/footer.php

在这个文件中，如果一切正常，您可以自动登录客户，并延长cookie生存期，在每次加载页面时都使用页脚，所以我的意思是，这是一种很好的方式。

  public function index() {
    [...]
    $data['scripts'] = $this->document->getScripts('footer');
    $data['styles'] = $this->document->getStyles('footer');

    if (isset($_COOKIE["MyCustomerID"]) && isset($_COOKIE["MyEmail"]) && $_COOKIE["MyCustomerID"] != '' && $_COOKIE["MyEmail"] != '') {
      $my_customer_id_crypted = $_COOKIE["MyCustomerID"];
      $my_customer_id = $this->decrypt($my_customer_id_crypted, "your_key_for_customer_id_encryption");

      $my_email_crypted = $_COOKIE["MyEmail"];
      $my_email = $this->decrypt($my_email_crypted, "your_key_for_email_encryption");

      $config = new Config();
      $config->load('default');

      if ( $my_customer_id != "" && $my_email != "" && $my_customer_id == (int)$my_customer_id ) {
        if ( !$this->customer->isLogged() ) {          
          if ( $my_customer_id == $this->getCustomerIdByEmailAddress( $my_email ) ) { // auto login, when customer ID belongs to this email address
            $this->customer->login($my_email, "", true); // we use OpenCart override log in method
            //$this->log->write('customer logged in automatically');

            $this->load->model('account/address');

            if ($this->config->get('config_tax_customer') == 'payment') {
              $this->session->data['payment_address'] = $this->model_account_address->getAddress($this->customer->getAddressId());
            }

            if ($this->config->get('config_tax_customer') == 'shipping') {
              $this->session->data['shipping_address'] = $this->model_account_address->getAddress($this->customer->getAddressId());
            }

            // extend cookies lifetime
            setcookie("MyCustomerID", $my_customer_id_crypted , time() + (365 * 24 * 60 * 60) , "/");
            setcookie("MyEmail", $my_email_crypted , time() + (365 * 24 * 60 * 60) , "/");

            $this->response->redirect($_SERVER['REQUEST_URI']);
          }
        }
      }
    }
    [...]
  }

  // https://www.phpcluster.com/simple-two-way-encryption-in-php/
  // decrypt function for previous used encryption
  protected function decrypt($encryptedText, $key) {
    $key = md5($key);
    $iv = substr( hash( 'sha256', "aaaabbbbcccccddddeweee" ), 0, 16 );
    $decryptedText = openssl_decrypt(base64_decode($encryptedText), 'AES-128-CBC', $key, OPENSSL_RAW_DATA, $iv);
    return $decryptedText;
  }

  protected function getCustomerIdByEmailAddress($email) {
    $sql_txt = "";
    $sql_txt .= "SELECT customer_id";
    $sql_txt .= "  FROM ".DB_PREFIX."customer";
    $sql_txt .= " WHERE LOWER(email) = '".$this->db->escape(utf8_strtolower($email))."'";
    $customer_query = $this->db->query($sql_txt);

    if ($customer_query->num_rows)
    {
      return $customer_query->row['customer_id'];
    }
    else
    {
      return -1;
    }
  }

如果需要，可以改进此代码，目前我使用此方法自动登录客户。
