用我现在最常使用的php框架fastadmin举例子,当然thinkphp或者原生php也是同样的原理,大家理解思路就好了、
环境:fastadmin,summernote编辑器
【summernote的居中功能在段落里,且不会吃掉section标签,加上导入word功能之后,简直完美~】
按照国际惯例先放效果图
github上的demo里我还没有换图标,不过fastadmin里的是换了的,效果如下:
1、thinkphp使用composer安装phpword插件(这个插件能够把word转为html)
composer require phpoffice/phpword
安装完成之后的文件在vender目录下
2、打开require统一管理后台插件的js
引入我们需要的ajaxfileupload.js插件(这个插件允许文件通过ajax上传到服务器,而不是form表单)
\'ajaxfileupload\':\'../libs/ajaxfileupload/ajaxfileupload\',
3、以新增新闻的编辑器为例,打开
在开头载入需要的组件
define([\'jquery\', \'bootstrap\', \'backend\', \'table\', \'form\',\'summernote\',\'layer\',\'ajaxfileupload\'], function ($, undefined, Backend, Table, Form,summernote,layer,ajaxfileupload) {
然后修改add方法
add: function () {
Controller.api.bindevent();
var imageButton = function (context) {
var ui = $.summernote.ui;
var button = ui.button({
contents: \'<i class="fa fa-file-image-o"/>\',
tooltip: __(\'Choose\'),
click: function () {
parent.Fast.api.open("general/attachmentlect?element_id=&multiple=true&mimetype=image/*", __(\'Choose\'), {
callback: function (data) {
var urlArr = data.url.split(/\,/);
$.each(urlArr, function () {
var url = Fast.api.cdnurl(this);
context.invoke(\'editor.insertImage\', url);
});
}
});
return false;
}
});
return button.render();
};
var attachmentButton = function (context) {
var ui = $.summernote.ui;
var button = ui.button({
contents: \'<i class="fa fa-file"/>\',
tooltip: __(\'Choose\'),
click: function () {
parent.Fast.api.open("general/attachmentlect?element_id=&multiple=true&mimetype=*", __(\'Choose\'), {
callback: function (data) {
var urlArr = data.url.split(/\,/);
$.each(urlArr, function () {
var url = Fast.api.cdnurl(this);
var node = $("<a href=\'" + url + "\'>" + url + "</a>");
context.invoke(\'insertNode\', node[0]);
});
}
});
return false;
}
});
return button.render();
};
// 新增编辑器导入word功能
var wordBtn = function (context) {
var ui = $.summernote.ui;
var button = ui.button({
contents: \'<i class="fa fa-file-word-o"/>\',
tooltip: \'导入word\',
click: function () {
// 点击之后的操作
layer.open({
type: 1,
skin: \'layui-layer-rim\', //加上边框
area: [\'420px\', \'160px\'], //宽高
content: \'<input type="file" id="file" name="file" title="上传word" value="" ><br/><input type="button" value="上传" id="submit" />\'
});
}
});
return button.render(); // return button as jquery object
};
$(".summernote,.editor", $(\'form\')).summernote({
height: 250,
lang: \'zh-CN\',
fontNames: [
\'Arial\', \'Arial Black\', \'Serif\', \'Sans\', \'Courier\',
\'Courier New\', \'Comic Sans MS\', \'Helvetica\', \'Impact\', \'Lucida Grande\',
"Open Sans", "Hiragino Sans GB", "Microsoft YaHei",
\'微软雅黑\', \'宋体\', \'黑体\', \'仿宋\', \'楷体\', \'幼圆\',
],
fontNamesIgnoreCheck: [
"Open Sans", "Microsoft YaHei",
\'微软雅黑\', \'宋体\', \'黑体\', \'仿宋\', \'楷体\', \'幼圆\'
],
toolbar: [
[\'style\', [\'style\', \'undo\', \'redo\']],
[\'font\', [\'bold\', \'underline\', \'strikethrough\', \'clear\']],
[\'fontname\', [\'color\', \'fontname\', \'fontsize\']],
[\'para\', [\'ul\', \'ol\', \'paragraph\', \'height\']],
[\'table\', [\'table\', \'hr\']],
[\'insert\', [\'link\', \'picture\', \'video\']],
[\'select\', [\'image\', \'attachment\']],
[\'view\', [\'fullscreen\', \'codeview\', \'help\',\'word\']],
],
buttons: {
image: imageButton,
attachment: attachmentButton,
word:wordBtn
},
dialogsInBody: true,
followingToolbar: false,
callbacks: {
onChange: function (contents) {
$(this).val(contents);
$(this).trigger(\'change\');
},
onInit: function () {
},
onImageUpload: function (files) {
var that = this;
//依次上传图片
for (var i = 0; i < files.length; i++) {
Upload.api.send(files[i], function (data) {
var url = Fast.api.cdnurl(data.url);
$(that).summernote("insertImage", url, \'filename\');
});
}
}
}
});
// 点击上传按钮,发送ajax,上传word文档,并获取到返回的html地址
// 动态生成的元素需要使用在document上加点击事件
$(document).on(\'click\',\'#submit\',function(){
var path = $(\'#file\').val();
if ($.trim(path) == "") {
alert("请选择要上传的文件");
return;
}
$.ajaxFileUpload({
url: \'form\', //这里是服务器处理的代码
type: \'post\',
secureuri: false, //一般设置为false
fileElementId: \'file\', // 上传文件的id、name属性名
dataType: \'json\', //返回值类型,一般设置为json、application/json
success: function (data, status) {
console.log(\'success\')
},
error:function(data, status, e){
console.log(\'error\')
var responseText = data.responseText;
// console.log(responseText);
// 把html赋值给富文本,,并关闭layui
$(\'.layui-layer-close\').click();
$(".summernote,.editor", $(\'form\')).summernote(\'code\',responseText);
}
});
});
},
4、修改控制器
use PhpOffice\PhpWord\PhpWord;
...
public function form(){
// 接收表单上传的文件,并存储到服务器中
$file = $_FILES[\'file\'][\'tmp_name\'];//上传的文件
move_uploaded_file($file,"/words/res.docx");
// 使用phpword将word转为html
$phpWord = IOFactory::load(\'/words/res.docx\');
$xmlWriter = IOFactory::createWriter($phpWord, "HTML");
$resPath = \'/words/res.html\';
$xmlWriter->save($resPath);
$html = file_get_contents($resPath);
return $html;
}
5、记得public目录下创建一个words文件夹,用来存储word和html文件
----------------------------------------------------------------------------------------
实践过程中发现base64格式的代码太长、太占空间,于是决定将base64格式的图片转为普通格式的图片,存入服务器
1、修改phpoffice\phpword\src\PhpWord\Element\Image.php
在这个类文件的最后新增一个方法,用于将base64格式的图片转为普通格式图片存入服务器
public function base64_image_content($base64_image_content,$path){
//匹配出图片的格式
if (preg_match(\'/^(data:\s*image\/(\w+);base64,)/\', $base64_image_content, $result)){
$type = $result[2];
$new_file = $path."/".date(\'Ymd\',time())."/";
if(!file_exists($new_file)){
//检查是否有该文件夹,如果没有就创建,并给予最高权限
mkdir($new_file, 0700);
}
$new_file = $new_file.time().rand(100000000000, 900000000000).".{$type}"; // 如果同时上传多张图片,则时间戳相同会存在覆盖,因为加上随机上确保图片名称不重复
if (file_put_contents($new_file, base64_decode(str_replace($result[1], \'\', $base64_image_content)))){
return \'/\'.$new_file;
}else{
return false;
}
}else{
return false;
}
}
2、提前创建好存放图片的文件夹
D:/phpstudy_pro/WWW/word/public/word_images
3、修改phpoffice\phpword\src\PhpWord\Writer\HTML\Element\Image.php
原先是将图片以base64格式返回的,改为html里访问服务器图片的格式并返回
public function write()
{
if (!$this->element instanceof ImageElement) {
return \'\';
}
$content = \'\';
$imageData = $this->element->getImageStringData(true);
if ($imageData !== null) {
$styleWriter = new ImageStyleWriter($this->element->getStyle());
$style = $styleWriter->write();
$imageData = \'data:\' . $this->element->getImageType() . \';base64,\' . $imageData;
// 1、获取到项目根目录
// ---- D:/phpstudy_pro/WWW/word/vendor/phpoffice/phpword/src/PhpWord/Writer/HTML/Element/
$path = str_replace(\'\\\',\'/\',realpath(dirname(__FILE__).\'/\'))."/";
// --- D:/phpstudy_pro/WWW/word
$path = explode(\'/vendor/phpoffice/phpword/src/PhpWord/Writer/HTML/Element/\',$path)[0];
// 2、调用在类中新增的方法,将图片存入 D:/phpstudy_pro/WWW/word/public/word_images
$imageData = $this->element->base64_image_content($imageData, $path.\'/public/word_images\');
// 3、替换为html里要显示的格式,替换时根据项目的默认路径灵活修改
$imgPath = str_replace($path."/","",$imageData); // 原生php版本
// $imgPath = str_replace($path."/public/","",$imageData); // thinkphp版本
$content .= $this->writeOpening();
// 4、返回
$content .= "<img border=\"0\" style=\"{$style}\" src=\"{$imgPath}\"/>";
$content .= $this->writeClosing();
}
return $content;
}
4、原生php的demo(框架的demo实在太大了,就不放出来了,大家同理自己改写下就好)
下载项目部署到服务器上,访问form.html即可查看效果~
