ThinkPHP file upload tutorial,
File uploading is a common function in many PHP program projects. Today, this article will share a complete example to implement the ThinkPHP file uploading function. The specific method is as follows:
1. Action part:
FileAction.class.php page code is as follows:
<?php class FileAction extends Action{ function index(){ $file=M('file'); $list=$file->select(); $this->assign('filelist',$list); $this->display(); } function upload(){ //文件上传地址提交给他,并且上传完成之后返回一个信息,让其写入数据库 if(empty($_FILES)){ $this->error('必须选择上传文件'); }else{ $a=$this->up(); if(isset($a)){ //写入数据库的自定义c方法 if($this->c($a)){ $this->success('上传成功'); } else{ $this->error('写入数据库失败'); } }else{ $this-error('上传文件异常,请与系统管理员联系'); } } } private function c($data){ $file=M('file'); $num = '0'; for($i = 0; $i < count($data)-1; $i++) { $data['filename']=$data[$i]['savename']; if( $file->data($data)->add()) { $num++; } } if($num==count($data)-1) { return true; }else { return false; } } private function up(){ //完成与thinkphp相关的,文件上传类的调用 import('@.Org.UploadFile');//将上传类UploadFile.class.php拷到Lib/Org文件夹下 $upload=new UploadFile(); $upload->maxSize='1000000';//默认为-1,不限制上传大小 $upload->savePath='./Public/Upload/';//保存路径建议与主文件平级目录或者平级目录的子目录来保存 $upload->saveRule=uniqid;//上传文件的文件名保存规则 $upload->uploadReplace=true;//如果存在同名文件是否进行覆盖 $upload->allowExts=array('jpg','jpeg','png','gif');//准许上传的文件类型 $upload->allowTypes=array('image/png','image/jpg','image/jpeg','image/gif');//检测mime类型 $upload->thumb=true;//是否开启图片文件缩略图 $upload->thumbMaxWidth='300,500'; $upload->thumbMaxHeight='200,400'; $upload->thumbPrefix='s_,m_';//缩略图文件前缀 $upload->thumbRemoveOrigin=1;//如果生成缩略图,是否删除原图 if($upload->upload()){ $info=$upload->getUploadFileInfo(); return $info; }else{ $this->error($upload->getErrorMsg());//专门用来获取上传的错误信息的 } } } ?>
2. View template part:
The template file index.html code is as follows:
<html> <body> <volist name="filelist" id="vo"> 小图:<img src="__PUBLIC__/upload/s_{$vo['filename']}" /><br /> 大图:<img src="__PUBLIC__/upload/m_{$vo['filename']}" /><br /> </volist> <form action="__URL__/upload" method="post" enctype="multipart/form-data"> <input type="file" name="file[]" /><br /> <input type="file" name="file[]" /><br /> <input type="file" name="file[]" /><br /> <input type="submit" value="上传" /> </form> </body> </html>
I believe that the examples described in this article can serve as a reference for everyone’s ThinkPHP program development.
