CodeIgniter Form始终发送“0”数据 [英] CodeIgniter Form always sends '0' data

问题描述

我认为我的算法是错误的，我不知道为什么。你能告诉我的错误吗？
这里是问题：每次刷新我的页面，它总是发送'0'到每个字段，即使我还没有填写表单。

I think my algorithm is wrong and I don't know why. Could you please tell my mistake ? Here is the problem : Everytime I refresh my page, it always sends '0' to each field, even I have not filled the form yet.

控制器：

function index() {
    $this->load->helper('form');
    $this->load->helper('url');
    $this->load->helper('html');
    $data = array (
        'nama' =>$this->input->post('nama'),
        'email' =>$this->input->post('email'),
        'telepon' =>$this->input->post('telepon'),
        'line' =>$this->input->post('line')
        );
        $this->load->model('site_model');
        $this->site_model->add_record($data);
        $this->load->view('index');
}

模型：

class Site_model extends CI_Model {
    function add_record($data) {
        $this->load->database();
        $this->db->insert('tabel_data', $data);
        return;
    }
}

index.php中的一些行（视图） / p>

Some lines from index.php (view) :

<tr>
     <td><p><label>Nama</label></p></td>
     <td>: <input type="text" name="nama" id="nama" title="Tolong isi nama" autofocus required></td>

我的截止日期很接近：D

Help me, please !! My deadline is so close :D

推荐答案

因为你不检查表单验证是否正在运行。
因此，当您输入索引控制器时，它的行为就像是来自一个表单发布，所有的值都被赋值为零。
在初始化数据数组之前，你应该检查是否有表单来了。
在你的控制器你应该检查：

because you do not check whether the form validation is running or not. So when you enter the index controller it behaves like it is coming from a form post so all the values are assigned to zero. You should check whether there is a form coming or not before initializing your data array. In your controller you should check :

 $this->load->library('form_validation');   
     if ($this->form_validation->run() == TRUE){
              $data = array (
              'nama' =>$this->input->post('nama'),
              'email' =>$this->input->post('email'),
              'telepon' =>$this->input->post('telepon'),
               'line' =>$this->input->post('line')
               );
              $this->load->model('site_model');
              $this->site_model->add_record($data);
              $this->load->view('index');
    }
    else
    {
        $this->load->view('index');
    }
