想要在代码点火器中使用电子邮件和移动设备登录

Question

>Controller：

public function index(){
$this->load->helper(array('form', 'url','common'));
$this->load->library(array('form_validation','session'));
$data=array(   
'header' => $this->load->view('frontend/assets/header', '', TRUE),  
'footer' => $this->load->view('frontend/assets/footer', '', TRUE),
);    
$this->form_validation->set_rules('email', 'email', 'trim|required');
$this->form_validation->set_rules('password', 'Password', 'trim|required');    
$this->load->model('usermodel','usermodel',TRUE); 
$form_post_data = $_POST;
// print_r($form_post_data);exit;
$email = $form_post_data['email'];
$password = $form_post_data['password'];
// $mobile = $form_post_data['mobile'];
if(count($form_post_data) >0)
{      

if ($this->form_validation->run() == FALSE)
{
$this->load->view('frontend/index',$data);
}
else
{       
$user_data  = $this->usermodel->checklogin($email,$password);   
var_dump($user_data);exit;
if(count($user_data) > 0)     
{
$this->session->set_userdata('sess_user_id', $user_data->id);
$this->session->set_userdata('sess_user_email', $user_data->email);
$this->usermodel->update_last_login_date();
echo "<script>
alert('Login Successfull.');
window.location.href = '" . base_url() . "profile';
</script>";
}
else 
{
$this->session->set_flashdata('err_msg', 'email or password is invalid please try again');
echo "<script>
alert('Email and Password is wrong.');
window.location.href = '" . base_url() . "home';
</script>";
}
} 
}
else {
$this->load->view('frontend/user/login',$data);
}
}

型：

function checklogin($email,$password)
{
// unset($data['sbt']);
$sha_password = md5($password);
// print_r($email);
// print_r($sha_password);exit;
$this->db->select('*');
$this->db->from('user');
$this->db->where('email', $email)
// $this->db->where("status","live")
->group_start()
->or_where('mobile', $email)
->group_end();
$this->db->where('password', $sha_password);
$query = $this->db->get(); 
return $query->row();
}

视图：

<form action="<?php echo base_url();?>user" method="POST" autocomplete="off">
<div class="field">
<input type="text" name="email" id="email" placeholder="E-mail or Phone">
<label for="email">E-mail</label>
</div>
<div class="field">
<input type="password" name="password" id="password" placeholder="password">
<div toggle="#password-field" class="fa fa-fw fa-eye field-icon toggle-password" id="log_pass" ></div>
<label for="password">password</label>
</div>
<button type="submit" name="sbt" class="modal__form_btn">Login</button>
<a href="#" class="modal__forgot_link">Forgot Password ?</a>
</form>

想要在代码点火器中使用电子邮件和移动设备登录。我试图使用电子邮件或电话在 CI 中创建登录功能。我无法这样做，控制器中使用的$user_data正在获取null值。这是我感到关切的主要原因。请帮我同样的忙。我有 3-4 种类型的 or_where 变体，但没有一种对我有用。

Answer 1

为什么不尝试直接使用 $_POST 而不是使用变量

$email = $_POST['email'];

或者您可以使用代码点火器的输入类

$email = $this->input->post('email');

您也可以询问 post 变量是否存在，而不是计算 $_POST 变量

if(count($form_post_data) >0)
if(isset($_POST['email']))

Answer 2

试试这个：

$this->db->select('*');
$this->db->from('user');
$this->db->group_start();
$this->db->where('email', $email)->or_where('mobile', $email);
$this->db->group_end();
$this->db->where('password', $sha_password);
$query = $this->db->get();
