codeigniter图像上传不能抓取文件名

Question

我有尝试和尝试，我只是不能让我的形象上传。 当我试图回显它时，我不能抓住我的图像名称：S。

你能看到我做错了什么吗？

这里是我的控制器：

<?php 
//ADMIN PAGE 
if (! defined('BASEPATH')) exit('No direct script access'); 

class News extends CI_Controller { 


    //Write post when logged in as admin 
    function write() 
    { 

     //insert image 
     $config['upload_path'] = APPPATH .'/archive/img/news/'; 
     $config['allowed_types'] = 'gif|jpg|jpeg|png'; 
     $config['max_size']   = '9000'; 
     $config['encrypt_name']  = true; 

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

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

     $newsData = array(
      'headline'  => $this->input->post('headline'), 
      'description' => $this->input->post('description'), 
      'content'  => $this->input->post('content'), 
      'creater'  => $this->session->userdata('username'), 
      'ip'   => $this->session->userdata('ip'), 
      'imgPath'  => $file_data['file_name'] 
     ); 


     echo "<pre>"; 
     //print_r($this->upload->data()); 
     //print_r($file_data); 
     //print_r($_FILES); 
     //print_r($this->input->post()); 
     print_r($newsData); 
     echo "</pre>"; 


     $this->load->model('admin/news_model'); 
     $this->news_model->insertNews($newsData); 


     $data['main_content'] = 'admin/write_view'; 
     $this->load->view('template', $data); 

    } 

} 

而且我认为文件，其中我上载我的形象

<div id="inputStyle"> 


<?php 

echo form_open_multipart('admin/news/write'); 

echo form_input('headline', 'overskrift'); 

echo form_upload('newsImage'); 

echo form_textarea('description', 'indhold'); 

echo form_textarea('content', 'content'); 

echo form_submit('create', 'Opret nyhed'); 

echo form_close(); 


?> 




</div><!-- inputStyle -->

我编辑了自己的代码。它可能适合你。如果您的文件夹位于应用程序的根文件夹中，则无需使用APPPATH。我也在你的代码中编辑过。尝试这个。如果

//Write post when logged in as admin 
function write() 
{ 
    //insert image 
    $config['upload_path'] = 'archive/img/news/'; 
    $config['allowed_types'] = 'gif|jpg|jpeg|png'; 
    $config['max_size']   = '9000'; 
    $config['encrypt_name']  = true; 

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

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

    $newsData = array(
     'headline'  => $this->input->post('headline'), 
     'description' => $this->input->post('description'), 
     'content'  => $this->input->post('content'), 
     'creater'  => $this->session->userdata('username'), 
     'ip'   => $this->session->userdata('ip'), 
     'imgPath'  => $_FILES['newsImage']['name'] 
    ); 


    echo "<pre>"; 
    //print_r($this->upload->data()); 
    //print_r($file_data); 
    //print_r($_FILES); 
    //print_r($this->input->post()); 
    print_r($newsData); 
    echo "</pre>"; 


    $this->load->model('admin/news_model'); 
    $this->news_model->insertNews($newsData); 


    $data['main_content'] = 'admin/write_view'; 
    $this->load->view('template', $data); 
}
