php - 通过检查数据库中的密码并移至 codeigniter 中的下一页

Question

我正在尝试通过检查数据库中的密码和用户名来移动到 codeigniter 中的下一页。这是我的代码，问题是我在没有检查数据库的情况下进入页面。请帮忙。 App_stay_login.php页面

<?php echo form_open('Welcome/login','id="loginForm"'); ?> 
<div class="form-group">
<label class="sr-only" for="form-username">Username</label>
<input type="text" name="form-username" placeholder="Username..." class="form-username form-control" id="form-username">
</div>
<div class="form-group">
<label class="sr-only" for="form-password">Password</label>
<input type="password" name="form-password" placeholder="Password..." class="form-password form-control" id="form-password">
 </div>
<button type="submit" class="btn">Sign in!</button>    
<?php echo form_close(); ?>

public function index()
{
$data['admin'] = $this->Login_set->get_pass('form-password');

Controller

$count=$this->Login_set->set_pass();          
if($count > 0){
    $this->load->view('App_stay/pages/profile');
}else{
    $this->load->view('App_stay/App_stay_login');
}

型号

public function set_pass()
{
$this->load->helper('url');
$data = array(
'username1' => $this->input->post('form-username'),
'password1' => $this->input->post('form-password')
);
$sql = $this->db->select('*')->from('admin_login')
->group_start()
->where('admin_username', $data['username1']) //to access the value of array       
->where('admin_password', $data['password1']) //to access the value of array
->group_end()
->get();

return $query->num_rows($sql); //return number of affected rows
}
