Php 如何解决此错误opencart注意：未定义属性：Proxy:：GetTotalCustomersBytelPhone in

我使用opencart版本3.0.3.3

我试图用它来阻止客户注册中重复的电话号码

在

catalog/model/account/customer.php中添加新函数：
代码：全选

public function getTotalCustomersByTelephone($telephone) {
    $query = $this->db->query("SELECT COUNT(*) AS total FROM " . DB_PREFIX . "customer WHERE LOWER(telephone) = '" . $this->db->escape(utf8_strtolower($telephone)) . "'");

    return $query->row['total'];
}

    // Customer Group

    if ($this->model_account_customer->getTotalCustomersByTelephone($this->request->post['telephone'])) {
        $this->error['warning'] = $this->language->get('error_exists');
    } 

在第237行电话输入检查之后，在
目录/controller/account/register.php中
代码：全选

public function getTotalCustomersByTelephone($telephone) {
    $query = $this->db->query("SELECT COUNT(*) AS total FROM " . DB_PREFIX . "customer WHERE LOWER(telephone) = '" . $this->db->escape(utf8_strtolower($telephone)) . "'");

    return $query->row['total'];
}

    // Customer Group

    if ($this->model_account_customer->getTotalCustomersByTelephone($this->request->post['telephone'])) {
        $this->error['warning'] = $this->language->get('error_exists');
    } 

加：
代码：全选

public function getTotalCustomersByTelephone($telephone) {
    $query = $this->db->query("SELECT COUNT(*) AS total FROM " . DB_PREFIX . "customer WHERE LOWER(telephone) = '" . $this->db->escape(utf8_strtolower($telephone)) . "'");

    return $query->row['total'];
}

    // Customer Group

    if ($this->model_account_customer->getTotalCustomersByTelephone($this->request->post['telephone'])) {
        $this->error['warning'] = $this->language->get('error_exists');
    } 

但当注册为新客户时，结果会显示这一点

注意：未定义的属性：第245行/home/xxx/public\u html/catalog/controller/account/register.php中的Proxy:：getTotalCustomersBytelphone

我感激
谢谢，你说得对，只是我更新了现金，它工作正常。

return$query->row['total']？？无效确保清除了缓存中的修改
