最近几天正在做一个小型CMS,用到图片上传了,想利于CodeIgniter的上传类去实现,但测试中有好多问题,我把经过和要注意的地方分享一下!@H_404_1@
代码如下:
404_1@@H_404_1@ @H_404_1@/*注意,这里是userfile,$this->upload->do_upload(),这里do_upload默认上传文件的表单名为userfile;@H_404_1@当然也可以使用do_upload($filename),这里的$filename一定要和form_upload()里面的字符串一致.@H_404_1@我在这里范了糊涂,最后看了手册才明白,希望大家注意哦!@H_404_1@*/
代码:@H_404_1@
function upload() {@H_404_1@ $config['upload_path'] = './uploads/'; @H_404_1@ /*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!@H_404_1@ 否则就会报错"The upload path does not appear to be valid."; @H_404_1@ */@H_404_1@ $config['allowed_types'] = 'gif|jpg|png';@H_404_1@ /*我试着去上传其它类型的文件,这里一定要注意顺序! @H_404_1@ A problem was encountered while attempting to move the uploaded file to the final destination.@H_404_1@ 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! @H_404_1@ $config['allowed_types'] = 'zip|gz|png|gif|jpg';(正确)@H_404_1@ $config['allowed_types'] = 'png|gif|jpg|zip|gz';(错误)@H_404_1@ */@H_404_1@ $config['max_size'] = '1024';@H_404_1@ $config['max_width'] = '1024';@H_404_1@ $config['max_height'] = '768';$config['file_name'] = time(); //文件名不使用原始名@H_404_1@ $this->load->library('upload',$config);@H_404_1@ if(!$this->upload->do_upload()) {@H_404_1@ echo $this->upload->display_errors();@H_404_1@ }else{
$data['upload_data']=$this->upload->data(); //文件的一些信息@H_404_1@ $img=$data['upload_data']['file_name']; //取得文件名
echo $img."
";
foreach($data['upload_data'] as $item => $value){@H_404_1@ echo $item.":".$value."
";
}
