本地图文直接复制到富文本编辑器中

标签：复制到 function 文本编辑 word ueditor me 器中 var 上传

当前功能基于PHP，其它语言流程大抵相同。

大概流程：

1. 将docx文件上传到服务器中

2. 使用PHPoffice/PHPword实现将word转换为HTML

3. 将HTML代码返回并赋值到编辑器中

1 编辑器配置修改

1.1 新增上传word json配置

在ueditor\php\config.json中新增如下配置：

/* 上传word配置 */

"wordActionName": "wordupload", /* 执行上传视频的action名称 */

"wordFieldName": "upfile", /* 提交的视频表单名称 */

"wordPathFormat": "/public/uploads/word/{yyyy}{mm}{dd}/{time}{rand:6}", /* 上传保存路径,可以自定义保存路径和文件名格式 */

"wordMaxSize": 102400000, /* 上传大小限制，单位B，默认100MB */

"wordAllowFiles": [".docx"] /* 仅支持docx格式的word */

1.2 修改编辑器配置文件

1.2.1 在工具栏上新增按钮

在ueditor\ueditor.config.js文件中，新增按钮名称"wordupload"，并添加鼠标悬浮提示，如下所示：

//工具栏上的所有的功能按钮和下拉框，可以在new编辑器的实例时选择自己需要的重新定义

, toolbars: [[

'fullscreen', 'source', '|', 'undo', 'redo', '|',

'bold', 'italic', 'underline', 'fontborder', 'strikethrough', 'superscript', 'subscript', 'removeformat', 'formatmatch', 'autotypeset', 'blockquote', 'pasteplain', '|', 'forecolor', 'backcolor', 'insertorderedlist', 'insertunorderedlist', 'selectall', 'cleardoc', '|',

'rowspacingtop', 'rowspacingbottom', 'lineheight', '|',

'customstyle', 'paragraph', 'fontfamily', 'fontsize', '|',

'directionalityltr', 'directionalityrtl', 'indent', '|',

'justifyleft', 'justifycenter', 'justifyright', 'justifyjustify', '|', 'touppercase', 'tolowercase', '|',

'link', 'unlink', 'anchor', '|', 'imagenone', 'imageleft', 'imageright', 'imagecenter', '|',

'simpleupload', 'insertimage', 'emotion', 'scrawl', 'insertvideo', 'music', 'attachment', 'map', 'gmap', 'insertframe', 'insertcode', 'webapp', 'pagebreak', 'template', 'background', '|',

'horizontal', 'date', 'time', 'spechars', 'snapscreen', 'wordimage', '|',

'inserttable', 'deletetable', 'insertparagraphbeforetable', 'insertrow', 'deleterow', 'insertcol', 'deletecol', 'mergecells', 'mergeright', 'mergedown', 'splittocells', 'splittorows', 'splittocols', 'charts', '|',

'print', 'preview', 'searchreplace', 'drafts', 'help', 'wordupload'

]]

//当鼠标放在工具栏上时显示的tooltip提示,留空支持自动多语言配置，否则以配置值为准

,labelMap:{

'wordupload': '上传word文件',

}

在ueditor\themes\default\images\目录下新增按钮图标"word_upload.png"：

在ueditor\themes\default\css\ueditor.css文件中新增按钮样式：

.edui-for-wordupload .edui-icon {

width: 16px;

height: 16px;

background: url(../images/word_upload.png) no-repeat 2px 2px !important;

}

最后在ueditor\ueditor.all.js文件中editorui["simpleupload"] = function (editor){}后面添加如下代码：

/* word上传 */

editorui["wordupload"] = function (editor) {

var name = 'wordupload',

ui = new editorui.Button({

className:'edui-for-' + name,

title:editor.options.labelMap[name] || editor.getLang("labelMap." + name) || '',

onclick:function () {},

theme:editor.options.theme,

showText:false

});

editorui.buttons[name] = ui;

editor.addListener('ready', function() {

var b = ui.getDom('body'),

iconSpan = b.children[0];

editor.fireEvent('worduploadbtnready', iconSpan);

});

editor.addListener('selectionchange', function (type, causeByUi, uiReady) {

var state = editor.queryCommandState(name);

if (state == -1) {

ui.setDisabled(true);

ui.setChecked(false);

} else {

if (!uiReady) {

ui.setDisabled(false);

ui.setChecked(state);

}

});

return ui;

};

最终样式如下：

编辑

1.2.2 新增语言配置

在ueditor\lang\zh-cn\zh-cn.js文件中在"simpleupload"配置下方新增以下配置：

'simpleupload':{

'exceedSizeError': '文件大小超出限制',

'exceedTypeError': '文件格式不允许',

'jsonEncodeError': '服务器返回格式错误',

'loading':"正在上传...",

'loadError':"上传错误",

'errorLoadConfig': '后端配置项没有正常加载，上传插件不能正常使用！'

'wordupload':{

'exceedSizeError': '文件大小超出限制',

'exceedTypeError': '文件格式不允许',

'jsonEncodeError': '服务器返回格式错误',

'loading':"正在上传...",

'loadError':"上传错误",

'errorLoadConfig': '后端配置项没有正常加载，上传插件不能正常使用！'

在ueditor\lang\zh-cn\en.js文件中在"simpleupload"配置下方新增以下配置：

'simpleupload':{

'exceedSizeError': 'File Size Exceed',

'exceedTypeError': 'File Type Not Allow',

'jsonEncodeError': 'Server Return Format Error',

'loading':"loading...",

'loadError':"load error",

'errorLoadConfig': 'Server config not loaded, upload can not work.',

'wordupload':{

'exceedSizeError': 'File Size Exceed',

'exceedTypeError': 'File Type Not Allow',

'jsonEncodeError': 'Server Return Format Error',

'loading':"loading...",

'loadError':"load error",

'errorLoadConfig': 'Server config not loaded, upload can not work.',

1.2.3 修改过滤配置

由于导入word时，编辑器会自动过滤掉图片等样式，所以需取消过滤

在ueditor\ueditor.config.js文件中修改如下配置：

// xss 过滤是否开启,inserthtml等操作

,xssFilterRules: false

//input xss过滤

,inputXssFilter: false

//output xss过滤

,outputXssFilter: false

在ueditor\ueditor.all.js文件中，修改UE.plugins[‘defaultfilter’]，新增return ;如下所示：

// plugins/defaultfilter.js

///import core

///plugin 编辑器默认的过滤转换机制

UE.plugins['defaultfilter'] = function () {

return;

var me = this;

me.setOpt({

'allowDivTransToP':true,

'disabledTableInTable':true

});

……

2 添加相关功能

2.1 安装PHPword

composer require phpoffice/phpword

2.2 自定义文件转换类

实现上传文件，并将文件转换为HTML

直接将ueditor自带的上传文件"ueditor\php\Uploader.class.php"类复制到自定义类相同目录下

自定义WordToHtmlController.class.php文件：

<?php

class WordToHtmlController

{

public function index()

{

require 'vendor/autoload.php';

$base64 = "upload";

$config = array(

"pathFormat" => '/public/uploads/word/{yyyy}{mm}{dd}/{time}{rand:6}',

"maxSize" => 102400000,

"allowFiles" => [".docx"]

);

$fieldName = 'upfile';

include 'Uploader.class.php';

$up = new Uploader($fieldName, $config, $base64);

$path = ltrim($up->getFileInfo()['url'], '/');

// $phpWord = \PhpOffice\PhpWord\IOFactory::load('public/uploads/word/20211029/test.docx');

$phpWord = \PhpOffice\PhpWord\IOFactory::load($path);

// 直接输出到页面显示

// $phpWord->save('php://output', 'HTML');

$xmlWriter = \PhpOffice\PhpWord\IOFactory::createWriter($phpWord, 'HTML');

header("Content-Type:text/html; charset=utf-8");

exit($this->replaceImageSrc($xmlWriter->getContent()));

// exit($xmlWriter->getContent());

}

/**

* 将HTML代码中的所有图片地址替换

* @param $content string 要查找的内容

* @return string

private function replaceImageSrc($content)

{

$preg = '/(\s+src\s?\=)\s?[\'|"]([^\'|"]*)/is'; // 匹配img标签的正则表达式

preg_match_all($preg, $content, $allImg); // 匹配所有的img

if (!$allImg)

return $content;

foreach ($allImg[0] as $k => $v) {

$old = ltrim($v, '" src=');

preg_match('/^(data:\s*image\/(\w+);base64,)/', $old, $temp);

$tempType = $temp[2]; // 获取类型

// 判断目录是否存在，不存在时创建

$tempFilePath = 'public/uploads/word_images/' . date('Y-m-d', time());

if (!file_exists($tempFilePath))

mkdir($tempFilePath);

// 拼接完整路径

$tempFileName = $tempFilePath . '/word_image_' . time() . $k . '.' . $tempType;

$base64 = str_replace($temp[1], '', $old);

file_put_contents($tempFileName, base64_decode($base64));

// 替换路径字符串

$content = str_replace($old, $tempFileName, $content);

}

return $content;

}

2.3 编辑器实现导入操作

在ueditor\ueditor.all.js文件中UE.plugin.register('simpleupload', function (){})下方新增如下方法：

/**

* @description

* word上传:点击按钮,直接选择文件上传

UE.plugin.register('wordupload', function (){

var me = this,

isLoaded = false,

containerBtn;

function initUploadBtn(){

var w = containerBtn.offsetWidth || 20,

h = containerBtn.offsetHeight || 20,

btnIframe = document.createElement('iframe'),

btnStyle = 'display:block;width:' + w + 'px;height:' + h + 'px;overflow:hidden;border:0;margin:0;padding:0;position:absolute;top:0;left:0;filter:alpha(opacity=0);-moz-opacity:0;-khtml-opacity: 0;opacity: 0;cursor:pointer;';

domUtils.on(btnIframe, 'load', function(){

var timestrap = (+new Date()).toString(36),

wrapper,

'</form>' +

'<iframe id="edui_iframe_' + timestrap + '" name="edui_iframe_' + timestrap + '" style="display:none;width:0;height:0;border:0;margin:0;padding:0;position:absolute;"></iframe>';

btnIframeBody.parentNode.style.width = w + 'px';

btnIframeBody.parentNode.style.height = w + 'px';

}

var form = btnIframeDoc.getElementById('edui_form_' + timestrap);

var input = btnIframeDoc.getElementById('edui_input_' + timestrap);

var iframe = btnIframeDoc.getElementById('edui_iframe_' + timestrap);

domUtils.on(input, 'change', function(){

showErrorLoader && showErrorLoader(me.getLang('wordupload.loadError'));

form.reset();

showErrorLoader(me.getLang('wordupload.exceedTypeError'));

return;

domUtils.on(iframe, 'load', callback);

// 上传操作

// form.action = utils.formatUrl(imageActionUrl + (imageActionUrl.indexOf('?') == -1 ? '?':'&') + params);

// 替换请求地址为框架后台地址

form.action = "/admin.php?m=fwordToHtml&a=index"

form.method = "post"

form.submit();

});

var stateTimer;

me.addListener('selectionchange', function () {

clearTimeout(stateTimer);

stateTimer = setTimeout(function() {

var state = me.queryCommandState('wordupload');

if (state == -1) {

input.disabled = 'disabled';
