Добавьте пользователей с помощью CodeIgniter

Question

Прежде всего, я новичок здесь, и я действительно не знаю, как использовать codeigniter, и теперь я запутался. Поэтому в настоящее время я пытаюсь добавить данные в базу данных с помощью codeigniter. Когда я нажимаю кнопку «Отправить», ничего не отображается, поэтому я проверил мою базу данных и никаких записей не было добавлено. Можете ли вы, ребята, помочь мне?

Answer 1

сделать некоторые изменения в AddUser() в контроллере,

public function adduser(){ 
 
    $this->load->library('form_validation'); 
 
    $this->load->helper('security'); 
 
    $this->form_validation->set_rules('username','Username','required|min_length[4]|trim|callback_users_exist|xss_clean'); 
 
      $this->form_validation->set_rules('password','Password','trim|required|min_length[6]|max_length[50]|matches[password_conf]|md5|trim|xss_clean'); 
 
      $this->form_validation->set_rules('password_conf','Confirmed Password','trim|required|min_length[6]|max_length[50]|matches[password_conf]|md5|trim|xss_clean'); 
 
      $this->form_validation->set_rules('firstname','Firstname','trim|required|xss_clean'); 
 
      $this->form_validation->set_rules('middlename','Middlename','trim|required|xss_clean'); 
 
      $this->form_validation->set_rules('lastname','Lastname','trim|required|xss_clean'); 
 
      $this->form_validation->set_rules('screenname','Screenname','trim|required|xss_clean'); 
 
      $this->form_validation->set_rules('gender','Gender','trim|required'); 
 
      $this->form_validation->set_rules('position','Position','trim|required'); 
 

 
if($this->form_validation->run()){ 
 
    $this->load->model('model_emp'); 
 
    $data = array(
 
       'username' =>$this->input->post('Username'), 
 
       'password' =>$this->input->post('Password'), 
 
       'firstname' =>$this->input->post('Firstname'), 
 
       'middlename' =>$this->input->post('Middlename'), 
 
       'lastname' =>$this->input->post('Lastname'), 
 
       'screenname' =>$this->input->post('Screenname'), 
 
       'gender'  =>$this->input->post('Gender'), 
 
       'position' =>$this->input->post('Position'), 
 
       ); 
 

 
    $result=$this->model_emp->addusers($data); 
 
    if(!$result){ 
 
        echo mysqli_error($result); 
 
       }else{ 
 
        echo "<div class='alert alert-success alert-dismissable'> 
 
        <button type='button' class='close' data-dismiss='alert' aria-hidden='true'>×</button>Successfully Added</div>"; 
 
       } 
 
      } 
 
      echo validation_errors("<div class='alert alert-danger alert-dismissable'><button type='button' class='close' data-dismiss='alert' aria-hidden='true'>×</button>","</div>"); 
 
     }

И при изменении модели functi на к,

public function addusers($data=null){  
 
    if(!empty($data)){ 
 
     $this->db->insert('table_name',$data); 
 
     $ins_id = $this->db->insert_id(); 
 
     return $ins_id; 
 
    } else { 
 
     return false; 
 
    } 
 
}

Вот пример кода, из которого вы можете получить представление, контроллер управляет вашими логическими моделями приложений, а работа с базой данных и просмотр - это ваши веб-страницы.

Контроллер: user.php

function registration() 
{ 
    $this->load->library('form_validation'); 
     $this->form_validation->set_rules(array(
      array(
       'field' => 'username', 
       'label' => 'Username', 
       'rules' => 'trim|required' 
      ), 
      array(
       'field' => 'password', 
       'label' => 'Password', 
       'rules' => 'trim|required' 
      ) 
     )); 

     if(!$this->form_validation->run()) 
     { 
      $this->load->view('registration_view'); 
     } 
     else 
     { 
      $this->load->model('user_model'); 
      $user = new users_model(); 
      $user->username = $this->input->post('username'); 
      $user->password = $this->input->post('password'); 
      $user->save(); 
     } 
} 

вид: registraion_form.php

<form action="<?php echo site_url('user/registration'); ?>" method="post"> 
<input type="text" name="username" value="<?php echo set_value('username'); ?>" /> 
<input type="password" name="password" value="<?php echo set_value('password'); ?>" /> 
<input type="submit" name="submit" value="submit"/> 
</form> 

Модель: user_model.php

public $username; 
public $password; 

public function save() 
{ 
    $data = array(
    'username' => $this->username, 
    'password' => $this->password 
    ); 
    $this->db->insert('table-name', $data); 
} 

Answer 3

Если im right, это означает, что ваш контроллер должен содержать значения post из представления.

$username = $this->input->post('Username') 

Вы должны включать все поля, так что работа формы проверки, в противном случае она выдаст ошибку (которая может быть пустой страницей).

Итак, вместо того, что вы сделали с вашей моделью. это должно выглядеть примерно так вместо того, чтобы,

public function addusers($username, $email, $password, $emp_name, $position, $emp_pic){ 
    $data = array(
    'username' => $username , 
    'email' => $email , 
    'password' => $password, 
    'emp_name' => $emp_name, 
    'position' => $position, 
    'emp_pic' => path_to_your_employee_pic 
); 

$this->db->insert('employee', $data); 
} 

с аргументами, переданными из контроллера

$this->model_emp->addusers($username, $email, $password, $emp_name, $position, $emp_pic);
