端代码：
<!DOCTYPE html> <html> <head> <meta charset="utf-8"> <title>upload模块快速使用</title> <link rel="stylesheet" href="/layui/css/layui.css" media="all"> </head> <body> <button type="button" class="layui-btn" id="test1"> <i class="layui-icon"></i>上传图片 </button> <div class="layui-upload-list"> <img class="layui-upload-img" width="100px" height="100px" id="demo1"> <p id="demoText"></p> </div> <script src="/layui/layui.js"></script> <script> layui.use('upload', function(){ var $ = layui.jquery ,layer = layui.layer ,upload = layui.upload; var uploadInst = upload.render({ elem:'#test1' ,url:'/index/upload/upload' ,accept:'file' // 允许上传的文件类型 ,auto:true // 自动上传 ,before:function (obj) { // console.log(obj); // 预览 obj.preview(function(index,file,result) { // console.log(file.name); //图片地址 // console.log(file.type); //图片格式 // console.log(file.size); //图片大小 // console.log(file); //图片地址 $('#demo1').attr('src',result); //图片链接 base64 }); } // 上传成功回调 ,done:function(res) { // console.log(upload); console.log(res); if (res.code == 0) { layer.msg(res.msg); }else{ layer.msg(res.msg); } } // 上传失败回调 ,error:function(index,upload) { // 上传失败 } }); }) </script> </body> </html>
php后台：
public function upload() { $file = request()->file('file'); $info = $file->move(ROOT_PATH . 'public' . DS . 'uploads'); if($info) { $data['code'] = 0; $data['msg'] = $info->getSaveName(); }else{ $data['code'] = 1; $data['msg'] = $file->getError(); } return json($data); }
