我正在尝试创建一个基本登录,没有错误检查或任何其他东西,以努力习惯codeigniter。下面是我的控制器类方法,我试图将模型方法的结果传回来验证用户名和密码。
public function login()
{
if (isset($_POST['email'])) {
$this->cdata['email'] = $_POST['email'] ;
} else {
$this->cdata['email'] = "";
}
if (isset($_POST['password'])) {
$this->cdata['password'] = $_POST['password'];
} else {
$this->cdata['password'] = "";
}
$this->load->model("dbaccess");
$this->loggedin = $this->dbaccess->check_input($this->cdata['email'], $this->cdata['password']);
if($this->loggedin == TRUE) {
$this->load->view('carerview', $this->cdata);
} else {
$this->cdata['warning'] = "Check failed ! Please try again";
$this->load->view('mainview', $this->cdata);
}
}
我认为的帖子似乎运作正常。帖子被发送回主登录/索引,下面的方法登录(如上所示)显示我的模型类,它在我的登录方法中在控制器中调用它到目前为止只有一个方法。 check_input()
class Dbaccess extends CI_Model
{
function __construct()
{
parent::__construct();
}
function check_input($email, $password)
{
$this->db->select('email');
$this->db->from('tablename');
$this->db->where('email', $email);
$this->db->where('password', $password);
$query = $this->db->get();
if ($query->num_rows() > 0) {
return TRUE;
} else {
return FALSE;
}
}
}
当我在索引页面上点击提交时,无论如何我都会收到警告,而我无法确定问题所在。

尝试它是否有效:
function login()
{
if( $this->input->post( null ) ){ #check if the post array is not blank
$this->load->model("dbaccess");
$this->loggedin = $this->dbaccess->check_input($this->input->post('email'),$this->input->post('password'));
}else{
$this->loggedin = false;
}
if($this->loggedin == TRUE)
{$this->load->view('carerview',$this->cdata);}
else
{$this->cdata['warning']="Check failed ! Please try again";
$this->load->view('mainview',$this->cdata);
}
}

你的表实际上是名为tablename吗?只是尝试调试它,在check_input函数中尝试这个并发布结果(如果需要,更改用户名/通道):
function check_input($email,$password)
{
var_dump($email);
var_dump($password);
$this->db->select('email');
$this->db->from('tablename');
$this->db->where('email', $email);
$this->db->where('password', $password);
$query = $this->db->get();
echo $this->db->last_query();
if (!$query) {
// if query returns null
$msg = $this->db->_error_message();
exit("Error: ".$msg);
}
if($query->num_rows() > 0)
{
return TRUE;
}
else
{
return FALSE;
}
}
