本文实例讲述了Thinkphp框架+Layui实现图片/文件上传功能。分享给大家供大家参考，具体如下：
在项目中用到了，再网上找了现成的代码都是借口异常或者非法上传，所以在一番摸索搞定之后拿来和大家分享。

layui.use('upload', function(){ var $ = layui.jquery ,upload = layui.upload; //普通图片上传 var uploadInst = upload.render({ elem: '#uploadBanner' ,url: "{:U('Api/doUploadPic')}" ,before: function(obj){ //预读本地文件示例，不支持ie8 obj.preview(function(index, file, result){ $('#upload-photo').attr('src', result); //图片链接（base64） $('#upload-photo').attr('style', 'height:10rem;'); $('#upload-icon').attr('style','display:none;'); }); } ,done: function(res, index, upload){ //如果上传失败 if(res.code > 0){ return layer.msg('上传失败'); } //上传成功 console.log("成功啦！" + obj2string(res) + " " + index + " " + upload); } ,error: function(){ //演示失败状态，并实现重传 var demoText = $('#demoText'); demoText.html('<span style="color: #FF5722;">上传失败</span> <a class="layui-btn layui-btn-xs demo-reload">重试</a>'); demoText.find('.demo-reload').on('click', function(){ uploadInst.upload(); }); } });}); |

public function doUploadPic()//上传模块 { $upload = new \Think\Upload(); $upload->maxSize = 3145728; $upload->exts = array('jpg', 'gif', 'png', 'jpeg'); $upload->rootPath = './Public/'; // 设置附件上传根目录 $upload->savePath = 'upload/'; // 设置附件上传子目录 $info = $upload->upload(); if(!$info){ $this->error($upload->getError()); }else{ foreach($info as $file){ $data = '/Public'.$file['savepath'] . $file['savename']; $file_a=$data; echo '{"code":0,"msg":"成功上传","data":{"src":"'.$file_a.'"}}'; } } } |
图片就上传到/Public/upload文件夹下了：
希望本文所述对大家基于ThinkPHP框架的PHP程序设计有所帮助。
