        **Controller file i have form_ctrl.php and code given below**
        <?php
        defined('BASEPATH') OR exit('No direct script access allowed');

        class form_ctrl extends CI_Controller {

            public function index()
            {
                //$this->load->view('welcome_message');
                     $this->load->helper(array('form', 'url'));
                     $this->load->library('form_validation');
                     $this->load->model('data_model');

                        $this->form_validation->set_rules('address', 'Address','required|min_length[5]');

                        if ($this->form_validation->run() == FALSE)
                        {
                                $this->load->view('table');

                        else
                        {
                              $this->load->view('results');

                                     $data = array(
                                                   'name' =>$name ,

                                    $this->data_model->insert_fun('form', $data);

                                               }
                }
         function GetAll()
          {

               $this->load->view('emp_viewall',$data);
          }

              }


    **model file i have data_model.php**

    <?php
    class data_model extends CI_Model {

        function __construct() { 
            parent::__construct (); 
        }

        public function insert_fun($tableName,$data){

           return $this->db->insert($tableName, $data);

        }
    function emp_getall()
      {
           $this->load->database();
           $query=$this->db->get('form');
           return $query->result();
      }
    }


    ?>


view file i have results.php

<html>
<head>
<title>My Form</title>
</head>
<body>
<table width="100%" border="1">
<tr>
    <td>Name</td>
    <td>Email</td>
    <td>Mobile</td>
    <td>Address</td>
    <td>Action</td>
</tr>
 <?php
foreach($query as $row)
{
  print_r($row);exit;

}
?> 
<tr>
    <td></td>
    <td></td>
    <td></td>
    <td></td>
    <td></td>
</tr>


</table>


</body>
</html>

数据插入正确，但视图未显示数据库字段，这意味着 IN 模型文件函数（函数 emp_getall()）或控制器文件（函数 GetAll()）不起作用给我解决方案，该代码中的错误...

【问题讨论】：

标签： codeigniter

【解决方案1】：

function GetAll()
          {
             $this->load->model('emp_model');
               $data['query']=$this->emp_model->emp_getall();
               $this->load->view('results',$data);
          }

你错误的视图调用检查这个

【讨论】：

兄弟你 print_r 在控制器中你得到记录或在你的视图中传递数据后不检查
hothi jimit bro i m newbe in codeigniter 但它无法正常工作，没有获得任何价值

【解决方案2】：

    <html>   <head>
<title>My Form</title>
</head>
<body>
<table width="100%" border="1">
<tr>
    <td>Name</td>
    <td>Email</td>
    <td>Mobile</td>
    <td>Address</td>
    <td>Action</td>
</tr>
 <?php
foreach($query as $row) : ?>
<tr>
    <td><?php echo $row->name;?></td>
    <td><?php echo $row->email;?></td>
    <td><?php echo $row->mobile;?></td>
    <td><?php echo $row->address;?></td>
    <td><?php echo $row->action;?></td>
</tr>


</table>
<?php endforeach ?>

</body>
</html>

尝试一次......
