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>"; } } }
