图片上传器在 CI 中不工作

Question

这是我的浏览页面

<?php echo form_open_multipart('admin/item/uploadImage'); ?>
<input type="file" name="file" id="file" />
<td><?php echo form_submit('submit', 'Save', 'class="btn btn-primary"');?>

这是我的控制器页面：

class item extends Admin_Controller
{


public function __construct ()
{
    parent::__construct();
    $this->load->model('item_m');
}

public function index ()
{
    // Fetch all items
    $this->data['items'] = $this->item_m->get();
    // Load view
    $this->data['subview'] = 'admin/item/index';
    $this->load->view('admin/_layout_main', $this->data);


}




function uploadImage()

{

   $config['upload_path']   =   "uploads/";

   $config['allowed_types'] =   "gif|jpg|jpeg|png"; 

   $config['max_size']      =   "5000";

   $config['max_width']     =   "1907";

   $config['max_height']    =   "1280";

   $this->upload->initialize($config);
   $this->load->library('upload',$config);

   if(!$this->upload->do_upload($_POST['file']))

   {

       echo $this->upload->display_errors();

   }

   else

   {

       $finfo=$this->upload->data();

       $data['uploadInfo'] = $finfo;

       $data['thumbnail_name'] = $finfo['raw_name']. '_thumb' .$finfo['file_ext']; 

     //  $this->load->view('upload_success',$data);

       // You can view content of the $finfo with the code block below

       /*echo '<pre>';

       print_r($finfo);

       echo '</pre>';*/

   }

     //  $this->load->view('upload_success',$data);

       // You can view content of the $finfo with the code block below

       /*echo '<pre>';

       print_r($finfo);

       echo '</pre>';*/



}}

我收到这样的错误

A PHP Error was encountered
Severity: Notice
Message: Undefined index: file
Filename: admin/item.php
Line Number: 47
You did not select a file to upload.

请帮我文件数据没有传递到控制器页面？我也尝试从另一个函数调用 doupload 图像，但它也不起作用。

Answer 1

这个语句有问题：

if(!$this->upload->do_upload($_POST['file']))

此处您只需指定参数名称，例如：

if(!$this->upload->do_upload('file'))
