作为登录的一部分,我正在使用“用户”表中针对用户的密钥。我无法从数据库中获取密钥,然后使用它来解码密码。我从用户表中获取密钥,并不知道将值赋给变量$ data,认为从查询返回的值是一个数组我尝试将$ data变量引用为$ data [0]但是没有区别。
public function checklogin($Email,$Pass)
{
$data = $this->db->query(select Key from users where User = $Email);
$Password = $this->encrypt->decode($Pass,$data);
$this->db->select('User','Pwd','Level');
$this->db->from('users');
$this->db->where('User', $Email);
$this->db->where('Pwd', $Password);
$this->db->where('Active','Y');
$query = $this->db->get();
}

答案 0 :(得分:1)
替换
$query = $this->db->get();
使用以下行
$query = $this->db->get()->result_array();
