我已成功在Code Igniter中创建了注册和登录系统。 注册后，所有用户数据都保存在数据库中。 我在登录表单中使用了电子邮件和密码，我想显示与该登录用户相关的所有详细信息。
我尝试了一些但没有得到确切的东西。我该怎么办？

// While registering time your are using md5 encryption for password but while
// retrieving time you are passing password without encryption formate
$data = $this->db->query($sql, array($email,$pass));
// Use this in your model
$data = $this->db->query($sql, array($email,hash('md5', $pass)));
