Question

我无法在codeigniter中上传文件。我正在使用的代码：

<?php
defined('BASEPATH') OR exit('No direct script access allowed');

class Main extends CI_Controller {

    function __construct() {
    parent::__construct();
    $this->load->library('session');
    $this->load->library('upload');
    $this->load->library('form_validation');
    $this->load->helper(array('form', 'url'));
    $this->load->model('User_m');
    }
    public function form()
    {
        if($_POST){
            //print_r($_POST);exit;


                 if(!empty($_FILES['userfile']['name']))
                 {
                   $config['upload_path'] = "./uploads/";
                   $config['allowed_types'] = 'jpg|jpeg|png|gif';
                   $config['file_name'] = $_FILES['userfile']['name'];
                   //Load upload library and initialize configuration
                   //print_r($config);exit;
                   $this->load->library('upload',$config);
                   //$this->upload->initialize($config);

                   if($this->upload->do_upload('userfile')){
                       $uploadData = $this->upload->data();
                       $userfile = $uploadData['file_name'];
                       //echo $userfile;exit;
                   }
                   else
                   {
                       $userfile = '';
                   }
             }
             else
              {
                 $userfile = '';

              }
            $data['name']=$this->input->post('name');
            $data['email']=$this->input->post('email');
            $data['phone']=$this->input->post('phone');
            $data['userfile']=$userfile;
            $this->User_m->form_insert($data);
        }


        $this->load->view('form');
    }
}

这是我的控制器功能代码，用于在codeigniter中处理多部分表单数据。但是文件没有上传。

因为您已经给出了代码，所以我修改了代码以跟踪它。在下面，我附加了视图文件以及控制器文件：

1）下面是一个视图文件代码。在此方法中，我通过在action属性中指定方法名称来提交表单。如果要通过ajax提交表单，则可以在此传递方法名称。

<div id="container">
<h1>Please Fill up the Registration Form.!</h1>
<div id="body">
  <!-- <?php echo $error;?> --> 
  <form method="post" action="<?php echo site_url() . '/Main/form' ?>" enctype="multipart/form-data"> Full name:<br> <input type="text" name="name"><br> Email:<br> <input type="text" name="email"><br> Phone:<br> <input type="text" name="phone"><br><br> Image:<br> <input type="file" name="userfile" /> <br /><br /> <input type="submit"><br> </form>
</div>
</div>

2）以下是控制器代码。

 <?php

 class Main extends CI_Controller {

 public function __construct()
    {
            parent::__construct();
            $this->load->helper(array('form', 'url','html'));
    }

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


    public function form()
{

    if($_POST){



             if(!empty($_FILES['userfile']['name']))
             {
               $config['upload_path'] = "./uploads/";
               $config['allowed_types'] = 'jpg|jpeg|png|gif';
               $config['file_name'] = $_FILES['userfile']['name'];
               //Load upload library and initialize configuration
               //print_r($config);exit;
               $this->load->library('upload',$config);
               //$this->upload->initialize($config);

               if($this->upload->do_upload('userfile')){
                   $uploadData = $this->upload->data();
                   $userfile = $uploadData['file_name'];
                   //echo $userfile;exit;
               }
               else
               {
                   $userfile = '';
               }
         }
         else
          {
             $userfile = '';

          }
        $data['name']=$this->input->post('name');
        $data['email']=$this->input->post('email');
        $data['phone']=$this->input->post('phone');
        $data['userfile']=$userfile;

        // Below $data getting all the form data
        print_r($data);

    }


    $this->load->view('form');
}

}

希望这对您有帮助！

您可以尝试

<div class="item">
      <a href="#" target="_blank" class="standout">
    <div class="regcard cardlist" >
      number 1
        </div>
      </a>
  </div>
  
     <div class="item">
      <a href="#" target="_blank" class="standout">
    <div class="regcard cardlist" >
      number 2
        </div>
      </a>
  </div>
  
     <div class="item">
      <a href="#" target="_blank" class="standout">
    <div class="regcard cardlist" >
      number 3
        </div>
      </a>
