I have a error while uploading a pdf file in wamp server 5.2.1 in windows but it works fine in 5.3.x. It shows the userfile empty even when it is not empty in 5.2.1 wampp server.Here is the code.
controller

Code:

if (!empty($_FILES['userfile']['name'])) {
                
               $this->Notice_model->upload_image($id);
            }

model

Code:

function upload_image($filename) {
  
    
      $config = array(
          'allowed_types' => 'doc|docx|xls|xlsx|ppt|pptx|jpg|gif|jpeg|png|pdf|txt',
          'upload_path' => $this->path,
          'max_size' => 6291456,
          'file_name' => $filename
      );
       $this->load->library('upload', $config);
     if (!$this->upload->do_upload()) {
         $error = $this->upload->display_errors();
          die($error);
      }


   }

View

Code:

<?php echo form_open_multipart ('/notice/');?>
<table>
<tr>
                    <td>File</td>
                 <td>&lt;input type='file' name="userfile" id="userfile" &gt;&lt;/td>
                </tr>
</table>
&lt;?php echo form_close();?&gt;

So what's the problem? Just use wamp 5.3! It's not affecting your production server right? God!

You can try to add the mime type to your .htaccess file!

Code:

AddType application/pdf .pdf

I'm sorry for the offtopic banter, but your client plans to run his production server on Wamp?
