准备：
1.当前phpcms最新版本（自带ckeditor 版本为3.6.6）
2.准备替换的最新ckeditor,版本4.2.1
一、开始之前说下原版ckeditor与phpcms的ckeditor的一些主要区别：
1.原版的分页符是一个div标签，而phpcms中编辑器的是[page]。
2.phpcms编辑器下方，多了3个按钮，“分页符”，“子标题”，“附件上传”。
3.由于ckeditor的版本不一样，一些自己开发的插件不能兼容。
二、下面开始替换。
1.备份phpcms的 /statics/js/ckeditor 文件夹（重命名即可）。以及/phpcms/libs/classes/form.class.php （这个文件中有个方法就是创建一个编辑器，使用一些编辑器的工具栏配置需要在这里操作）
2.把新版ckedtior复制到/statics/js/下。打开/statics/js/ckeditor/config.js 文件，用旧版的config.js替换。但请注释掉 config.extraPlugins = ''; 这一行（我想应该是插件不兼容问题）

// Define changes to default configuration here. For example:
// config.language = 'fr';
// config.uiColor = '#AADC6E';
config.uiColor = '#f7f5f4';
config.width = '';
config.removePlugins = 'elementspath,scayt';
config.disableNativeSpellChecker = false;
config.resize_dir = 'vertical';
config.keystrokes =[[ CKEDITOR.CTRL + 13 /*Enter*/, 'maximize' ]];
config.extraPlugins = '';
config.enterMode = CKEDITOR.ENTER_BR;
config.shiftEnterMode = CKEDITOR.ENTER_P;
config.font_names='宋体/宋体;黑体/黑体;仿宋/仿宋_GB2312;楷体/楷体_GB2312;隶书/隶书;幼圆/幼圆;微软雅黑/微软雅黑;'+ config.font_names;
};</p> <p>
CKEDITOR.on( 'instanceReady', function( ev ){ with (ev.editor.dataProcessor.writer) { setRules("p", {indent : false, breakAfterOpen : false, breakBeforeClose : false} ); setRules("h1", {indent : false, breakAfterOpen : false, breakBeforeClose : false} ); setRules("h2", {indent : false, breakAfterOpen : false, breakBeforeClose : false} ); setRules("h3", {indent : false, breakAfterOpen : false, breakBeforeClose : false} ); setRules("h4", {indent : false, breakAfterOpen : false, breakBeforeClose : false} ); setRules("h5", {indent : false, breakAfterOpen : false, breakBeforeClose : false} ); setRules("div", {indent : false, breakAfterOpen : false, breakBeforeClose : false} ); setRules("table", {indent : false, breakAfterOpen : false, breakBeforeClose : false} ); setRules("tr", {indent : false, breakAfterOpen : false, breakBeforeClose : false} ); setRules("td", {indent : false, breakAfterOpen : false, breakBeforeClose : false} ); setRules("iframe", {indent : false, breakAfterOpen : false, breakBeforeClose : false} ); setRules("li", {indent : false, breakAfterOpen : false, breakBeforeClose : false} ); setRules("ul", {indent : false, breakAfterOpen : false, breakBeforeClose : false} ); setRules("ol", {indent : false, breakAfterOpen : false, breakBeforeClose : false} ); } });
//CKEDITOR.plugins.load('pgrfilemanager');
function insert_page(editorid)
{
var editor = CKEDITOR.instances[editorid];
editor.insertHtml('[page]');
if($('#paginationtype').val()) {
$('#paginationtype').val(2);
$('#paginationtype').css("color","red");
}
}</p> <p>function insert_page_title(editorid,insertdata)
{
if(insertdata)
{
var editor = CKEDITOR.instances[editorid];
var data = editor.getData();
var page_title_value = $("#page_title_value").val();
if(page_title_value=='')
{
$("#msg_page_title_value").html("<font color='red'>请输入子标题</font>");
return false;
}
page_title_value = '[page]'+page_title_value+'[/page]';
editor.insertHtml(page_title_value);
$("#page_title_value").val('');
$("#msg_page_title_value").html('');
if($('#paginationtype').val()) {
$('#paginationtype').val(2);
$('#paginationtype').css("color","red");
}
}
else
{
$("#page_title_div").slideDown("fast");
}
}
var objid = MM_objid = key = 0;
function file_list(fn,url,obj) {
$('#MM_file_list_editor1').append('<div id="MM_file_list_'+fn+'">'+url+' <a href=\'#\' onMouseOver=\'javascript:FilePreview("'+url+'", 1);\' onMouseout=\'javascript:FilePreview("", 0);\'>查看</a> | <a href="javascript:insertHTMLToEditor(\'<img src='+url+'>\',\''+fn+'\')">插入</A> | <a href="javascript:del_file(\''+fn+'\',\''+url+'\','+fn+')">删除</a>
');
}
3.打开/statics/js/ckeditor/ckeditor.js 做一些修改，目的是 把工具栏上的分页按钮与phpcms的分页保持一致。
找到：
CKEDITOR.plugins.pagebreakCmd={exec:function(a){var b=a.lang.pagebreak.alt,b=CKEDITOR.dom.element.createFromHtml('<div style="page-break-after: always;"contenteditable="false" style="margin: 3px auto 0px; padding: 0px 3px; outline: none; line-height: 21.6px; clear: both; border-width: 1px; border-style: solid; border-color: rgb(0, 153, 204); background: rgb(246, 251, 255); overflow: hidden; font-family: tahoma, arial, "Microsoft YaHei";">
复制代码
代码如下:
CKEDITOR.plugins.pagebreakCmd={exec:function(a){a.insertHtml('[page]');o=document.getElementById('paginationtype');o.options[2].selected = true}};
4.打开/phpcms/libs/classes/form.class.php 添加一些内容，目的是加上编辑器底部的三个按钮。（phpcms之前是在 ckeditor.js中做的。）
在下面代码后面
if(!defined('IMAGES_INIT')) {
$ext_str .= '<script type="text/javascript" src="'.JS_PATH.'swfupload/swf2ckeditor.js"></script>';
define('IMAGES_INIT', 1);
}
添加：
$ext_str.="<div class=\"cke_footer\">";
if(!$disabled_page){
$ext_str.="<a href=\"javascript:insert_page('content')\">分页符</a><a href=\"javascript:insert_page_title('content')\">子标题</a>";
}
$ext_str.="<a onclick=\"flashupload('flashupload', '附件上传','{$textareaid}','','{$allowuploadnum},{$alowuploadexts},{$allowbrowser}','{$module}','{$catid}','{$authkey}');;return false;\" href=\"javascript:void(0);\">附件上传</a>
</div>";
5.复制旧版ckeditor/skins/kama/images/文件夹下的文件 到 新版ckeditor/skins/moono/images/下。目的是一些样式的需要。
6.打开ckeditor\skins\moonoeditor_gecko.css文件，在最后加入三个按钮的样式即可
/*phpcms 新增编辑器底部按钮样式*/
.cke_top {
background: url("images/line.png") repeat-x scroll 0 0 transparent;
}
.cke_footer {
float: left;
margin-top: 3px;
}
.cke_footer a, .cke_footer a:hover, .cke_footer a:visited,.cke_footer a:active {
background: url("images/cke_fot.gif") repeat-x scroll left bottom transparent;
border: 1px solid #E0E0E0;
color: #666666;
cursor: pointer;
display: block;
float: left;
height: 19px;
line-height: 19px;
margin-right: 8px;
padding: 0 10px;
}
.cke_footer a:hover {
background-position: left top;
}</p> <p>
.editor_bottom {
clear: both;
height: 12px;
top:-28px;
position: relative;
}
#page_title_div {
display: none;
height: 78px;
left: 18px;
position: absolute;
top: -120px;
width: 295px;
z-index: 99999;
}
#page_title_div table {
background: none repeat scroll 0 0 #FFFFFF;
border: 2px solid #D5E0E6;
height: 78px;
width: 295px;
}
#page_title_div table td {
border: medium none;
}
#page_title_div table td.title {
color: #333333;
font: 18px/31px "MicroSoft YaHei","SimHei";
height: 26px;
margin: 0;
padding: 0 0 0 12px;
text-align: left;
}
#page_title_div a.close span {
display: none;
}
#page_title_div a.close {
background: url("images/cross.png") no-repeat scroll left 3px transparent;
display: block;
float: right;
height: 16px;
margin-right: 10px;
width: 16px;
}
#page_title_div a.close:hover {
background-position: left -46px;
}
.content_attr {
background: none repeat scroll 0 0 #FFFFCC;
border: 1px solid #CCCCCC;
margin-top: 6px;
padding: 5px 8px;
}
#Capture {
color: #474747;
font-size: 12px;
line-height: 20px;
}
#Capture font {
color: #FF0000;
}
#Capture a {
background: url("images/cdw.png") no-repeat scroll 0 0 transparent;
color: #0075C0;
display: inline-block;
padding-left: 20px;
text-decoration: none;
}
#Capture a:hover {
text-decoration: underline;
}
#Capture #CaptureDown {
background-image: url("images/cd.png");
}
到此，ckeditor编辑器升级完成，需要说明一下的是，phpcms本身自带一个capture插件，本次升级没有考虑它，一是用处不大，而是只能在ie中使用。
如有什么疑问或错误，请告知，谢谢！
