PHP3.2 implements multiple file uploads

This article mainly shares with you examples of how to implement multiple file uploads in php3.2. I hope it can help you.

public function upload(){ $upload = new \Think\Upload();// 实例化上传类 $upload->maxSize = 3145728 ;// 设置附件上传大小 $upload->exts = array('jpg', 'gif', 'png', 'jpeg');// 设置附件上传类型 $upload->rootPath = './Uploads/'; // 设置附件上传根目录 $upload->savePath = 'slider/'; // 设置附件上传（子）目录 // 上传单个文件 $info = $upload->uploadOne($_FILES['files']); if(!$info) {// 上传错误提示错误信息 $this->error($upload->getError()); }else{// 上传成功 获取上传文件信息 $url= $info['savepath'].$info['savename']; } return $url; }

This is the source code when uploading a single file, in which $info = $upload->uploadOne($_FILES['files']); This position limits the file upload to a single file

There is also the issue of front-end input selection

public function upload(){ $upload = new \Think\Upload();// 实例化上传类 $upload->maxSize = 3145728 ;// 设置附件上传大小 $upload->exts = array('jpg', 'gif', 'png', 'jpeg');// 设置附件上传类型 $upload->rootPath = './Uploads/'; // 设置附件上传根目录 $upload->savePath = 'last/'; // 设置附件上传（子）目录 // 上传多个文件 $info = $upload->upload(); if(!$info) {// 上传错误提示错误信息 $this->error($upload->getError()); }else{// 上传成功 获取上传文件信息 foreach($info as $file){ $url .= $file['savepath'].$file['savename'].','; } } return $url; }

This is a multi-file upload method. The main difference is $info = $upload->upload();This part

And $url .= $file['savepath'].$file['savename'].','; The limitations of this part

The difference between single file and multiple files on the front end is also very big

This is the difference between multiple files
