Question

我正在尝试创建一个简单的注册表单，但是无法将表单中的数据添加到我的数据库中？我做错了什么，数据不会发布到我的用户表？

如果验证失败，还只是再次加载视图不正确的事情？使用重定向只是失败，并说我应该尝试清除我的cookie。

我的代码如下。

注册控制器：

class Signup extends CI_Controller
{
public function index()
{
  $this->load->view('templates/header');
  $this->load->view('signup');
  $this->load->view('templates/footer');
}

function signup_validation() {
  $this->form_validation->set_rules('first_name', 'First Name', 'required');
  $this->form_validation->set_rules('last_name', 'Last Name', 'required');
  $this->form_validation->set_rules('username', 'Username', 'required|alpha_numeric|min_length[4]|is_unique[users.username]');
  $this->form_validation->set_rules('email', 'Email', 'required|valid_email|is_unique[users.email]');
  $this->form_validation->set_rules('password', 'Password', 'required|min_length[6]');
  $this->form_validation->set_rules('passconf', 'Password Confirmation', 'required|min_length[6]|matches[password]');
  if ($this->form_validation->run()) {
    $this->load->model('signup_model');
    redirect('login');
  }
  else {
    $this->load->view('templates/header');
    $this->load->view('signup');
    $this->load->view('templates/footer');
  }
}
}

注册模式：

class Signup_model extends CI_Model {
public function index()
{
  $url = url_title($this->input->post('user'), 'dash', true);

  $data = 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' => $this->input->post('password')
  );

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

注册视图

<form action="<?php echo site_url('signup/signup_validation') ?>" method="POST">

 <h5>First Name</h5>
 <input type="text" name="first_name" value="" />
 <span><?php echo form_error('first_name'); ?></span>

 <h5>Last Name</h5>
 <input type="text" name="last_name" value="" />
 <span><?php echo form_error('last_name'); ?></span>

 <h5>Username</h5>
 <input type="text" name="username" value="" />
 <span><?php echo form_error('username'); ?></span>

 <h5>Email Address</h5>
 <input type="text" name="email" value="" />
 <span><?php echo form_error('email'); ?></span>

 <h5>Password</h5>
 <input type="text" name="password" value="" />
 <span><?php echo form_error('password'); ?></span>

 <h5>Password Confirm</h5>
 <input type="text" name="passconf" value="" />
 <span><?php echo form_error('passconf'); ?></span>

 <div><input type="submit" value="Register" /></div>

</form>

您已加载模型但未加载函数

loading of a model guide

function signup_validation() {
    $this->form_validation->set_rules('first_name', 'First Name', 'required');
    $this->form_validation->set_rules('last_name', 'Last Name', 'required');
    $this->form_validation->set_rules('username', 'Username', 'required|alpha_numeric|min_length[4]|is_unique[users.username]');
    $this->form_validation->set_rules('email', 'Email', 'required|valid_email|is_unique[users.email]');
    $this->form_validation->set_rules('password', 'Password', 'required|min_length[6]');
    $this->form_validation->set_rules('passconf', 'Password Confirmation', 'required|min_length[6]|matches[password]');

    if ($this->form_validation->run()) {
        $this->load->model('signup_model');

        $this->signup_model->index();
        redirect('login');

    } else {

      $this->load->view('templates/header');
      $this->load->view('signup');
      $this->load->view('templates/footer');
    }

  }

}

注册数据没有插入Codeigniter中的数据库？重定向无法正常工作？
