例子一:
/** * 多文件上傳 * * @author Dream <[email protected]> */ public function multiple_uploads() { //載入所需類庫 $this->load->library('upload'); //配置上傳參數 $upload_config = array( 'upload_path' => '', 'allowed_types' => 'jpg|png|gif', 'max_size' => '500', 'max_width' => '1024', 'max_height' => '768', ); $this->upload->initialize($upload_config); //循環處理上傳文件 foreach ($_FILES as $key => $value) { if (!empty($key['name'])) { if ($this->upload->do_upload($key)) { //上傳成功 print_r($this->upload->data()); } else { //上傳失敗 echo $this->upload->display_errors(); } } } }
例子二:
function upload() { $config['upload_path'] = './uploads/'; /*這裡的uploads是相對於index.php的,也就是入口文件,這個千萬不要弄錯哦! 否則就會報錯"The upload path does not appear to be valid."; */ $config['allowed_types'] = 'gif|jpg|png'; /*我試著去上傳其它類型的文件,這裡一定要注意順序! A problem was encountered while attempting to move the uploaded file to the final destination. 這個錯誤一般是上傳文件的文件名不能是中文名,這個很郁悶!還未解決,大家可以用其它方法,重新改一下文件名就可以解決了! $config['allowed_types'] = 'zip|gz|png|gif|jpg';(正確) $config['allowed_types'] = 'png|gif|jpg|zip|gz';(錯誤) */ $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>"; } } }

試試加上?
因為使用上傳類你可以設置上傳目錄
所以這個時候其實你是知道直接目錄的,那對應的存入數據庫只要存儲文件名稱就可以了
如果目錄是變動的(例如按年月日變動),因為也是你事先知道的,也可以組織好對應的相對路徑存儲到數據庫
如果寫在對應的配置文件中,即可當變量使用了
