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/'; $config['allowed_types'] = 'gif|jpg|png'; $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>"; } }}
