CodeIgniter: Je rencontre cette erreur de base de données 1048 lors de la soumission du formulaire d'inscription.

Question

Je publie cette erreur de base de données sur localhost lors de la soumission du formulaire d'inscription lors de l'insertion de valeurs utilisateur dans la base de données.

Une erreur de base de données Occurred Numéro d'erreur: 1048 colonne 'prenom' ne peut pas être null INSERT INTO utilisateurs (prenom, last_name, nom d'utilisateur, email, mot de passe) VALUES (NULL, NULL, NULL, '', « d41d8cd98f00b204e9800998ecf8427e «)

Ceci est mon code (application/modèle/model_user)

<?php 

class Model_users extends CI_Model{ 

    public function can_log_in(){ 

     $this->db->where('email', $this->input->post('email')); 
     $this->db->where('password', md5($this->input->post('password'))); 
     $query = $this->db->get('users'); 

     if($query->num_rows() == 1){ 
      return TRUE; 
     } 
     else { 
      return FALSE; 
     } 
    } 

    public function add_user(){ 

     $first_name = $this->input->post('first_name'); 
     $last_name = $this->input->post('last_name'); 
     $username = $this->input->post('username'); 
     $email = $this->input->post('email'); 
     $password = md5($this->input->post('password')); 

     $sql = "INSERT INTO users(first_name, last_name, username, email, password) 
     VALUES(" .$this->db->escape($first_name). ", 
       " .$this->db->escape($last_name). ", 
       " .$this->db->escape($username). ", 
       '".$email."', 
       '".$password."')"; 

     $query = $this->db->query($sql); 
     if($query){ 
      return TRUE; 
     } 
     else{ 
      return FALSE; 
     } 
    } 
} 

?> 

J'ai aussi essayé cette requête d'insertion, mais encore la même erreur db

$new_members = array( 
      'first_name' => $this->input->post('first_name'), 
      'last_name' => $this->input->post('last_name'), 
      'username' => $this->input->post('username'), 
      'email' => $this->input->post('email'), 
      'password' => md5($this->input->post('password')) 
     ); 

     $insert = $this->db->insert('users', $new_members); 
     if($insert){ 
      return TRUE; 
     } else { 
      return FALSE; 

Ci-dessous est le fichier du contrôleur (application/controllers/main). Pas une telle erreur dans ce fichier, la validation de formulaire fonctionne aussi correctement.

<?php 

class Main extends CI_Controller{ 

    public function index() { 
     $this->login();

    else {

    } 
    } 

    public function restricted(){ 
     $this->load->view('restricted'); 
    } 

    public function login_validation(){

     if($this->form_validation->run()){ 

      $data = array(

       'is_logged_in' => 1 
      ); 
      $this->session->set_userdata($data); 

      redirect('main/members'); 
     } 
     else{ 
      $this->load->view('login'); 
     } 
    }

     $this->form_validation->set_rules('first_name','First Name','required');

     $this->form_validation->set_rules('password','Password','required|trim'); 
     $this->form_validation->set_rules('cpassword','Confirm Password','required|trim|matches[password]'); 

     $this->form_validation->set_message('is_unique','That email address already exist!'); 

     if($this->form_validation->run()){ 

      //echo 'Validation Successful.'; 
      redirect('main/add_user'); 
     } 
     else { 
      //Validation failed 
      $this->load->view('signup'); 
     } 
    } 

    public function add_user(){ 
     $this->load->model('model_users'); 
     $result = $this->model_users->add_user(); 

     if($result){ 
      $this->load->view('success'); 
     } 
     else{ //this should never happen 
      echo 'Sorry, there is a problem with a site. Please try again!' ; 
     } 
    } 

    public function validate_credentials(){ 
     $this->load->model('model_users'); 

     if($this->model_users->can_log_in()){ 
      return TRUE; 
     } 
     else{ 
      $this->form_validation->set_message('validate_credentials','Sorry incorrect Email ID or Password'); 
      return FALSE ; 
     } 

    } 

    public function logout(){ 
     $this->session->sess_destroy(); 
     redirect('main/login'); 
    } 

}
