我们使用ThinkPHP6框架经常需要文件上传,以下是封装的单文件上传控制器,结合layui前端框架,实现上传,只需调用该方法,传递存储文件夹名,为何要传递文件夹名呢?实则是为了方便管理文件。
1、后端控制器代码:
<?php /** *公共文件上传 * User: Hm * Date: 2020/9/16 * Email: <2938039696@qq.com> **/ declare (strict_types = 1); namespace app\union\controller; use think\exception\ValidateException; class Upload extends Base { /* * 单文件上传 * */ public function uploadImg(){ //判断是否是POST请求,如果是处理上传逻辑 if (request()->isPost()){ //接收文件上传目录 $namePath = request()->param('type'); //获取表单上传文件 $file = request()->file('file'); $upload_dir = '/'.$namePath; //组装文件保存目录 $suffix='jpg,jpeg,png,gif'; //文件格式 $size='3'; //文件大小 try { //验证器验证上传的文件 validate(['file'=>[ //限制文件大小 'fileSize' => $size * 1024 * 1024, //限制文件后缀 'fileExt' => 'jpg,jpeg,png,gif' ]],[ 'file.fileSize' => '上传的文件大小不能超过'.$size.'M', 'file.fileExt' => '请上传后缀为:'.$suffix.'的文件' ])->check(['file'=>$file]); //上传文件到本地服务器 $filename = \think\facade\Filesystem::disk('public')->putFile($upload_dir, $file); ; if ($filename){ $src = '/uploads/'.str_replace('\\', '/', $filename); return json(['code'=>1,'msg'=>'上传成功','data'=>['src'=>$src]]); }else{ return json(['code'=>0,'msg'=>'上传失败']); } }catch (ValidateException $e){ return json(['code'=>0,'msg'=>$e->getMessage()]); } }else{ return json(['code'=>0,'msg'=>'非法请求']); } } } ?>
2、前端代码:
<div class="layui-form-item layui-form-text"> <label>ICON</label> <div> <div id="test10"> <i></i> <p>点击上传,或将文件拖拽到此处</p> <div id="uploadDemoView" {php}if( isset($sys_config->sys_icon) != '' ) echo 'style ="display:block !important;" ';{/php}> <hr> <img src="{php}if( isset($sys_config->sys_icon) != '' ) echo $sys_config->sys_icon ;{/php}" alt="上传成功后渲染" style="max-width: 196px"> <input type="hidden" name="sys_icon" id="sysIcon" value="{php}if( isset($sys_config->sys_icon) != '' ) echo $sys_config->sys_icon ;{/php}"> </div> </div> </div> </div>
3、Javascrpt代码:这里调用改方法并传递参数{type:'config'}
<script> layui.use(['upload','form'], function () { var form = layui.form ,layer = layui.layer ,upload = layui.upload ,$ = layui.$; //拖拽上传 upload.render({ elem: '#test10' ,url: '{:url("union.upload.uploadImg")}' //改成您自己的上传接口 ,exts:'jpg|png|gif|bmp|jpeg' // ,auto:false // // ,field:'' // ,bindAction:'#settingFile' ,data:{type:'config'} ,done: function(res){ layer.msg('上传成功'); layui.$('#uploadDemoView').removeClass('layui-hide').find('img').attr('src', res.data.src); layui.$('#sysIcon').attr('value', res.data.src); console.log(res) } }); }); </script>
