xajax为fckeditor添加自动保存功能

时间：2007-11-08

来源：互联网

注：
1.使用的xajax版本是0.5.4beta,fckeditor版本是2.4.3,通过xajax给fckeditor增加自动保存草稿功能,其他版本未测试
2.文章原创转载请注明 http://xajax.dayanmei.com/20.htm
3.请不要尝试，关闭浏览器后再载入【因为演示使用session关联用户，做项目时可以将内容存储到数据库，跟用户id关联就可以了】

复制PHP内容到剪贴板

PHP代码:

<?php
session_start();
define('ROOT_DIR',str_replace("\\","/",dirname(__FILE__)));
$cachedir = './cache/';

//清除超过1天的记录文件
function clearcache($dir,$date = 1) {
    $now = time();
    $time = $date * 60 * 60 * 24;
    if(!is_dir($dir)){
        die('error :dir' . $dir . ' is not exist');
        }
    $handle = opendir($dir);
    while(false !== ($filename = readdir($handle))) {
        if($filename == '.' OR $filename == '..' OR $filename == ''){
            continue;
            }
        if(($now - filemtime($dir.$filename)) > $time){
            @unlink($dir.$filename);
            }
    }
}

//替换特殊字符
function xml_escape($string) {
    return str_replace(array('&','"',"'",'<','>'),
        array('&','"',''','<','>'),
        $string
    );
}

//执行清理
clearcache($cachedir);

require_once('./xajax/xajax.inc.php');

$xajax = new xajax();
$xajax->registerFunction('autosave');
$xajax->registerFunction('loadcache');
$xajax->processRequest();
echo $xajax->getJavascript('./xajax');

//定义载入数据函数
function loadcache() {
    global $cachedir;
    $filename = $cachedir . session_id().'.txt';
    if(file_exists($filename)){
        $content = '';
        $handle = file($filename);
        foreach($handle as $key=>$val) {
            $content .= $val;
        }
        }else{
        $content = '';
        }
    $content = xml_escape($content);
    $obj = new xajaxResponse();
    $obj->call("SetContents('$content')");
    $obj->assign('autosavemsg','innerHTML',"成功载入数据");
    return $obj;
}

//定义自动保存函数
function autosave($content) {
    global $cachedir;
    $obj = new xajaxResponse();
    $content = mysql_escape_string($content);
    $filename = $cachedir . session_id() . ".txt";
    $fp = fopen($filename,"w+");
    fwrite($fp,$content);
    fclose($fp);
    if(file_exists($filename)){
        $obj->assign("autosavemsg","innerHTML","成功保存数据...");
        }
    return $obj;
}

function editor($editorid,$content = '') {
    //载入编辑器
    require_once('./fckeditor/fckeditor.php');
    $editor = new fckeditor($editorid);
    $editor->ToolbarSet = 'Basic';
    $editor->BasePath = '../fckeditor/';
    $editor->Value = $content;
    return $editor->createhtml();
}
