例子一：

/** * 多文件上传 *  * @author Dream <dream@shanjing-inc.com> */public function multiple_uploads() {  //载入所需类库  $this->load->library('upload');    //配置上传参数  $upload_config = array(      'upload_path'  => '',      'allowed_types' => 'jpg|png|gif',      'max_size'   => '500',      'max_width'   => '1024',      'max_height'  => '768',  );  $this->upload->initialize($upload_config);      //循环处理上传文件  foreach ($_FILES as $key => $value) {    if (!empty($key['name'])) {      if ($this->upload->do_upload($key)) {        //上传成功        print_r($this->upload->data());      } else {        //上传失败        echo $this->upload->display_errors();      }    }  }}

例子二：

function upload() {    $config['upload_path'] = './uploads/';     /*这里的uploads是相对于index.php的,也就是入口文件,这个千万不要弄错哦!    否则就会报错"The upload path does not appear to be valid.";     */    $config['allowed_types'] = 'gif|jpg|png';    /*我试着去上传其它类型的文件,这里一定要注意顺序!     A problem was encountered while attempting to move the uploaded file to the final destination.    这个错误一般是上传文件的文件名不能是中文名,这个很郁闷!还未解决,大家可以用其它方法,重新改一下文件名就可以解决了!     $config['allowed_types'] = 'zip|gz|png|gif|jpg';(正确)    $config['allowed_types'] = 'png|gif|jpg|zip|gz';(错误)    */    $config['max_size'] = '1024';    $config['max_width'] = '1024';    $config['max_height'] = '768';    $config['file_name'] = time(); //文件名不使用原始名    $this->load->library('upload', $config);    if(!$this->upload->do_upload()) {        echo $this->upload->display_errors();    }else{       $data['upload_data']=$this->upload->data(); //文件的一些信息       $img=$data['upload_data']['file_name']; //取得文件名       echo $img."<br>";       foreach($data['upload_data'] as $item => $value){       echo $item.":".$value."<br>";      }    }}
