用CodeIgniter的上传类实现上传图片,测试中遇到一些问题,这里分享下要注意的地方:
<?php echo form_open_multipart('picture/upload');?> <?php echo form_upload('userfile');?> /*注意,此处是userfile,$this->upload->do_upload(),这里do_upload默认上传文件的表单名为userfile; 当然也可以使用do_upload($filename),此处的$filename一定要和form_upload()里面的字符串一致. */ <?php echo form_close();?>
controller控制器代码:
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>"; } } }
