本文实例讲述了thinkphp5 框架结合plupload实现图片批量上传功能,分享给大家供大家参考,具体如下:
在extend目录下新增目录uploader,并新建类Uploads
- <?php
- namespace uploader;
- class Uploads {
- public static function upfile($file, $path = 'images', $add_domain = false) {
- $res = ['errno' => 1, 'errmsg' => '上传图片错误'];
- $data = '';
- if(!emptyempty($file)) {
- // 上传根目录
- $file_path = 'uploads/';
- // 如果传了路径过来,则加入路径
- if(!emptyempty($path)) {
- $file_path .= $path .'/';
- }
- if (!file_exists($file_path)) {
- @mkdir($file_path);
- }
- // 上传
- $info = $file->move($file_path);
- // 获取后缀
- $ext = strtolower($info->getExtension());
- //判断后缀是否合法
- $exts = ['jpg', 'png', 'gif', 'jpeg', 'mp4', 'avi', '3gp'];
- if(in_array($ext, $exts)) {
- $save_name = $info->getSaveName();
- $save_path = "/" . $file_path . $save_name;
- if($add_domain) {
- $save_path = "http://www.localhost.com/" . $file_path . $save_name;
- }
- $res = ['errno' => 0, 'data' => $save_path];
- } else {
- $res = ['errno' => 1, 'errmsg' => $ext];
- }
- } else {
- $res = ['errno' => 1, 'errmsg' => '请选择图片!'];
- }
- return $res;
- }
- }
- ?>
使用
- <?php
- namespace app\backend\controller;
- use think\Controller;
- use think\Request;
- use uploader\Uploads;
- class Upload extends Controller
- {
- public function upload(Request $request) {
- $files = $request->file("file");
- $updir = $request->post('updir');
- $res = Uploads::upfile($files, $updir);
- return json_encode($res);
- }
- public function del_upload(Request $request) {
- $res = ['errno' => 1, 'errmsg' => '删除失败'];
- $filename = $request->post('filename');
- if(!emptyempty($filename)) {
- @unlink($_SERVER['DOCUMENT_ROOT'] . $filename);
- $res = ['errno' => 0, 'errmsg' => $filename];
- }
- return json_encode($res);
- }
- }
- ?>
前端js
- var image_files = new Array(); // 多图片上传临时保存
- $(document).ready(function() {
- $('.media-picker').each(function() {
- var el = $(this);
- var elbtn = el.find('.media-picker-button');
- var multi_selection = false;
- var inputField = el.find('input[type=hidden]');
- // 是否多文件上传
- if(elbtn.attr('data-multiple') == 'multiple') {
- multi_selection = true;
- }
- // 上传目录
- var upload_path = inputField.attr('upload-path');
- var uploader = new plupload.Uploader({
- runtimes : 'html5,flash,silverlight,html4',
- browse_button : elbtn.attr('data-id') + '_uploader',
- multi_selection: multi_selection,
- auto_start: true,
- flash_swf_url : '../plugins/plupload/js/Moxie.swf',
- silverlight_xap_url : '../plugins/plupload/js/Moxie.xap',
- url : '/backend/upload',
- filters: {
- mime_types : [ //只允许上传图片和zip,rar文件
- { title : "Image files", extensions : "jpg,jpeg,gif,png,bmp" },
- { title : "Video files", extensions : "mp4,3gp" }
- ],
- max_file_size : '10mb', //最大只能上传10mb的文件
- prevent_duplicates : false //不允许选取重复文件
- },
- init: {
- PostInit: function() {},
- BeforeUpload: function(up, file) {
- up.setOption('multipart_params', {'updir': upload_path})
- },
- FilesAdded: function(up) {
- up.start(); //选择完后直接上传
- },
- FileUploaded: function(up, file, info) {
- if (info.status == 200)
- {
- var file_type = file.type;
- var is_image = file_type.indexOf('image');
- var is_video = file_type.indexOf('video');
- // 解析返回的数据
- var result = JSON.parse(info.response);
- var img_list = "";
- if(result.errno == 0) {
- // 返回的图片上传结果
- var file_name = result.data;
- if(multi_selection) {
- // 多图片上传不考虑视频
- if (is_image > -1) {
- // 存入临时数组
- image_files.push(file_name);
- inputField.val(JSON.stringify(image_files));
- for (var i = 0; i < image_files.length; i++) {
- img_list += "<li><img src='"+image_files[i]+"' /><span class='delete-image'>✖</span><p>"+image_files[i]+"</p></li>";
- }
- }
- } else {
- inputField.val(file_name);
- if (is_image > -1) {
- img_list = "<li><img src='"+result.data+"' /><span class='delete-image'>✖</span><p>"+result.data+"</p></li>";
- }
- if (is_video > -1) {
- img_list = "<li><video controls src='"+result.data+"'></video><span class='delete-image'>✖</span><p>"+result.data+"<p></li>";
- }
- }
- el.find('.image-list').html(img_list);
- } else {
- alert(result.errmsg);
- }
- }
- else
- {
- alter(info.response);
- }
- },
- Error: function(up, err) {
- alert(err.response);
- }
- }
- })
- uploader.init();
- // 删除
- if (multi_selection) {
- el.on('click', '.delete-image', function() {
- var file_name = inputField.val();
- var elDel = $(this);
- // 得到filename
- var current_file_name = elDel.next('p').html();
- // 删除当前的父级li
- elDel.parent().remove();
- // 重新赋值数组
- var new_image_files = new Array();
- if (image_files != '') {
- new_image_files = image_files;
- } else {
- new_image_files = $.parseJSON(file_name);
- }
- // 去掉数组中的当前值
- for(var i in new_image_files) {
- if(new_image_files[i] == current_file_name) {
- new_image_files.splice(i,1);
- break;
- }
- }
- $.ajax({
- type: "POST",
- url: "/backend/del_upload",
- data: "filename=" + current_file_name,
- success: function(msg) {
- console.log(msg)
- }
- });
- inputField.val(JSON.stringify(new_image_files));
- });
- } else {
- el.on('click', '.delete-image', function(){
- // 显示值为空
- var file_name = inputField.val();
- el.find('.image-list').html('');
- inputField.val('');
- $.ajax({
- type: "POST",
- url: "/backend/del_upload",
- data: "filename=" + file_name,
- success: function(msg) {
- console.log(msg)
- }
- });
- });
- }
- })
- })
