使用这个库上传...它易于使用

http://demo.codesamplez.com/codeigniter/file-upload-demo

查看

<form action="" method="POST" enctype="multipart/form-data" > 
Select File To Upload:<br /> 
<input type="file" name="userfile" multiple="multiple" /> 
<input type="submit" name="submit" value="Upload" class="btn btn-success" /> 
</form> 

{if isset($uploaded_file)} 
{foreach from=$uploaded_file key=name item=value} 
{$name} : {$value} 
<br /> 
{/foreach} 
{/if} 

控制器

/** 
* the demo for file upload tutorial on codesamplez.com 
* @return view 
*/ 
public function file_upload_demo() 
{ 
try 
{ 
if($this->input->post("submit")){ 
$this->load->library("app/uploader"); 
$this->uploader->do_upload(); 
} 
return $this->view(); 
} 
catch(Exception $err) 
{ 
log_message("error",$err->getMessage()); 
return show_error($err->getMessage()); 
} 
} 

组件

/**

class Uploader { 
var $config; 
public function __construct() { 
$this->ci =& get_instance();

} 
public function do_upload(){

$config['upload_path'] = './uploads/'; 
    $config['allowed_types'] = 'gif|jpg|png'; 
    $config['max_size'] = '100'; 
    $config['max_width'] = '1024'; 
    $config['max_height'] = '768'; 

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

    if (! $this->upload->do_upload('image name')) 
    { 
     $error = array('error' => $this->upload->display_errors()); 

     $this->load->view('upload_form', $error); 
    } 
    else 
    { 
     $data = array('upload_data' => $this->upload->data()); 

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