phpcms v9编辑器ckeditor数据恢复功能
为phpcms v9的ckeditor编辑器开发的数据恢复功能.下面直接上步骤说明吧.
1.\statics\js\ckeditor\config.js文件最后增加以下代码:

//化蝶自在飞 add 2011-11-12 自动保存数据
var timer = counttimer = '30';//每?秒保存一次
var delays = 10;//延迟多少秒执行,因为firefox下无法显示,建议设置为10000
var editorid = 'content';
var fromid = 'myform';
$(function(){
var str = '<a href="javascript:void(0);" onclick="open_databak();return false;">恢复数据</a><span id="tuzwu_timer">'+timer+'</span>秒后自动保存';
setTimeout('$(".cke_footer").append(\''+str+'\')',delays*1000);
setInterval('tuzwu_posts()',timer*1000);
setInterval('tuzwu_timer()',1000);
});
function tuzwu_posts(){ //post提交数据
var editor = CKEDITOR.instances[editorid];
data = editor.getData();
$('#'+editorid).val(data);
$.post("api.php?op=editor_data", $("#"+fromid).serializeArray(),function(data){
$('#'+editorid).val();
});
}
function tuzwu_timer(){ //每秒执行1次,倒数计时
if(timer<=0) timer = counttimer;
$('#tuzwu_timer').html(--timer);
}
function open_databak(){
omnipotent('databak_area','?m=content&c=databak&a=init&target=dialog','恢复数据',1,600,400);
}

2.建数据表用于保存数据:

CREATE TABLE `v9_editor_data` (
  `id` mediumint(8) NOT NULL auto_increment,
  `data` mediumtext character set gbk NOT NULL COMMENT '数据',
  `time` int(10) NOT NULL,
  `userid` mediumint(8) NOT NULL,
  PRIMARY KEY  (`id`)
) ENGINE=MyISAM DEFAULT CHARSET=latin1 AUTO_INCREMENT=1 ;

注意:表前缀和数据库编码,推荐自己手工用phpmyadmin建表;

3.\phpcms\model\editor_data_model.class.php新建该文件,用以下代码填充文件:

<?php
defined('IN_PHPCMS') or exit('No permission resources.');
pc_base::load_sys_class('model', '', 0);
class editor_data_model extends model {
	public function __construct() {
		$this->db_config = pc_base::load_config('database');
		$this->db_setting = 'default';
		$this->table_name = 'editor_data';
		parent::__construct();
	}
}
?>

4.\api\editor_data.php新建改文件,用以下代码填充该文件:

<?php
defined('IN_PHPCMS') or exit('No permission resources.');
header('Content-type: text/html; charset=utf-8');
$db = pc_base::load_model('editor_data_model');
$_userid = param::get_cookie('userid');
if(!$_POST['info']['content']) exit('0');
$postinfo = array2string($_POST['info']);
$postdata = CHARSET != 'utf-8' ? iconv('utf-8', CHARSET, $postinfo ):$postinfo;
$posts = array(
'data'=>$postdata,
'userid'=>$_userid,
'time'=>SYS_TIME
);
$r = $db->get_one( array('userid'=>$_userid,'data'=>$postdata),'id' );//如果没有改变就不用备份
if($r) exit('0');
$db->insert($posts);
exit('1');
?>

5.\phpcms\modules\content\databak.php新建该文件,代码如下:

<?php
defined('IN_PHPCMS') or exit('No permission resources.');
//模型缓存路径
define('CACHE_MODEL_PATH',CACHE_PATH.'caches_model'.DIRECTORY_SEPARATOR.'caches_data'.DIRECTORY_SEPARATOR);
pc_base::load_app_func('util','content');
pc_base::load_app_class('admin','admin',0);
class databak extends admin {
	private $db;
	function __construct() {
		$this->db = pc_base::load_model('editor_data_model');
		$this->_userid = param::get_cookie('userid')?param::get_cookie('userid'):param::get_cookie('admin_userid');
		$this->_username = param::get_cookie('_username');
		$this->_groupid = param::get_cookie('_groupid');
	}

		public function init() {
        if(!$this->_userid) exit('用户ID校验失败');
		$page = $_GET['page']?$_GET['page']:1;
		$infos = $this->db->listinfo( array('userid'=>$this->_userid),'time DESC',$page,20,'',10 );
        $pages = $this->db->pages;
		$target = $_GET['target'];
		include $this->admin_tpl('databak');
		}
}
?>

6.\phpcms\modules\content\templates\databak.tpl.php新建改文件,代码如下:

<?php
header('Content-Type:text/html;charset=utf-8');
defined('IN_ADMIN') or exit('No permission resources.');
