layui+php多文件列表,多图上传,包含表单修改,可适用于laravel框架和tp框架 由于大量机器人刷广告本文已经禁止评论 由于本代码PHP上传部分是由PHP代码写得而不是用的框架写得,所以大部分情况可以直接用,有特殊情况的请自行修改。因为要实现增删改查所以文件上传后会赋值到隐藏的input框里代码后台部分： public function upload_images(Request $request)//上传图片,多图上传 { $file = $_FILES["file"]; if ($file==null) { exit(json_encode(array('code'=>1, 'msg'=>'未上传图片'))); } // 获取文件后缀 $temp = explode(".", $_FILES["file"]["name"]); $extension = end($temp); // 判断文件是否合法 if(!in_array($extension, array("gif","jpeg","jpg","png"))){ exit(json_encode(array('code'=>1, 'msg'=>'上传图片不合法'))); } //创建文件夹获取当前年月日 $folder="/mstyle/upload/images/".date('Y-m-d'); if(!is_dir('.'.$folder)){ mkdir('.'.$folder,0777);//创建年+月的文件夹权限为最高 } $info = move_uploaded_file($file['tmp_name'], '.'.$folder.'/'.$file['name']); //移动文件到指定目录 建议文件名自己在修改一下 $img = $folder.'/'.$file['name']; exit(json_encode(array('code'=>0, 'msg'=>$img))); } public function upload_files(Request $request)//文件上传 { $file = $_FILES["file"]; if ($file==null) { exit(json_encode(array('code'=>1, 'msg'=>'未上传图片'))); } // 获取文件后缀 $temp = explode(".", $_FILES["file"]["name"]); $extension = end($temp); // 判断文件是否合法 if(!in_array($extension, array("gif","jpeg","jpg","png"))){ exit(json_encode(array('code'=>1, 'msg'=>'上传文件不合法'))); } //创建文件夹获取当前年月日 $folder="/mstyle/upload/files/".date('Y-m-d'); if(!is_dir('.'.$folder)){ mkdir('.'.$folder,0777);//创建年+月的文件夹权限为最高 } $info = move_uploaded_file($file['tmp_name'], '.'.$folder.'/'.$file['name']); //移动文件到指定目录 建议文件名自己在修改一下 $img = $folder.'/'.$file['name']; exit(json_encode(array('code'=>0, 'msg'=>$img))); }可以看到两个方法几乎一样，那是因为当时写的时候只上传图片进行了测试，正常情况下上传文件需要修改判断文件类型那里前端代码： <div class="layui-form-item"> <div class="layui-upload"> <button type="button" class="layui-btn up-button" id="test2">多图片上传</button> <blockquote class="layui-elem-quote layui-quote-nm" style="margin-top: 10px;height: 142px;

layui+php多图上传 layui图片上传可以一次性选择多个图片,然后选择多少张调用多少次上传接口设计思路:前端上传文件到后台,后台接收保存成功后返回图片路径,前端根据路径生成div,div包括img标签、隐藏的input（表单传值用）、删除按钮,点击删除按钮判断是第几个删除按钮并删除对应的标签前端页面: <!doctype html> <html> <head> <meta charset="utf-8"> <title>多图上传</title> <link rel="stylesheet" href="https://www.layuicdn.com/layui/css/layui.css"> <script src="https://www.layuicdn.com/layui/layui.js"></script> <style> .up-img{ width: 100px; height: 100px; } #demo2 div button{ position: relative; top: -38px; left: -13px; } </style> </head> <body> <fieldset class="layui-elem-field layui-field-title" style="margin-top: 30px;"> <legend>上传多张图片</legend> </fieldset> <div class="layui-upload"> <button type="button" class="layui-btn" id="test2">多图片上传</button> <blockquote class="layui-elem-quote layui-quote-nm" style="margin-top: 10px; height: 142px;"> 预览图： <div class="layui-upload-list" id="demo2" ></div> </blockquote> </div> </body> <script> layui.use(['upload','jquery'],function () { $ = layui.jquery; var upload = layui.upload; //执行实例 var uploadInst = upload.render({ elem: '#test2' ,url: 'upload1.php' //改成您自己的上传接口 ,multiple: true ,before: function(obj){ //预读本地文件示例，不支持ie8 // console.log(obj); obj.preview(function(index, file, result){ // $('#demo2').append('<img src="'+ result +'" alt="'+ file.name +'" class="layui-upload-img up-img">') }); } ,done: function(res){ //上传完毕 $('#demo2').append('<div style="float: left;"><img src="'+ res.msg +'" alt="'+ res.msg +'" class="layui-upload-img up-img" onclick="showeq(this)"><input type="hidden" name="image[]" value="'+res.msg+'" onclick="showinput(this)"><button onclick="del(this)">x</button></div>'); // $('#demo2').append(''); // $('#demo2').append(''); } }); }); function showeq(params) { var index = $("#demo2 img").index(params); console.log(index); } function showinput(params) { var index = $("#demo2 input").index(params); console.log(index); } function del(params) { var index = $("#demo2 button").index(params); $("#demo2 button").eq(index).remove(); $("#demo2 input").eq(index).remove(); $("#demo2 img").eq(index).remove(); // console.log(index); } </script> </html>php代码<?php $file = $_FILES["file"]; if ($file==null) { exit(json_encode(array('code'=>1, 'msg'=>'未上传图片'))); } // 获取文件后缀 $temp = explode(".", $_FILES["file"]["name"]); $extension = end($temp); // 判断文件是否合法 if(!in_array($extension, array("gif","jpeg","jpg","png"))){ exit(json_encode(array('code'=>1, 'msg'=>'上传图片不合法'))); } $info = move_uploaded_file($file['tmp_name'], "./uploads/".$file['name']); //移动文件到指定目录 建议文件名自己在修改一下 $img = '/uploads/'.$file['name']; exit(json_encode(array('code'=>0, 'msg'=>$img))); ?>
