一:修改文件上传语言为PHP    
    打开fckconfig.js    
    找到:
    var _FileBrowserLanguage = 'asp'
    var _QuickUploadLanguage = 'asp'    
    改成:
    var _FileBrowserLanguage = 'php'
    var _QuickUploadLanguage = 'php'

二:启用PHP文件上传

    1:启用FileBrowser:
        打开fckeditor/editor/filemanager/browser/default/connectors/php/config.php
        启用文件上传:

        找到:
        $Config['Enabled'] = false

        改成:
        $Config['Enabled'] = true

        设置上传存放目录:

        找到:
        $Config['UserFilesPath'] = '/userfiles/'
        改成:
        $Config['UserFilesPath'] = '你自己的项目路径'

    2:启用QuickUpload
        打开fckeditor/editor/filemanager/upload/php/config.php
        启用文件上传:

        找到:
        $Config['Enabled'] = false
        改成:
        $Config['Enabled'] = true

        设置上传存放目录:

        找到:
        $Config['UserFilesPath'] = '/userfiles/'
        改成:
        $Config['UserFilesPath'] = '你自己的项目路径'



使用实例

<?php
$fck = $_POST [ " FCKeditor1 " ] ;
 if ( $fck != "" )
{
echo htmlspecialchars ( $fck ) ;
 }
?>

<html>
<head>
<title>fck测试</title>
</head>
<body>
<form action="index.php" method="POST">
 <?php
include ( " fckeditor/fckeditor.php " ) ; //加载文件
$oFCKeditor = new FCKeditor ( ' FCKeditor1 ' ) ; //创建一个FCKeditor对象 ID为FCKeditor1
$oFCKeditor -> BasePath = " /fck/fckeditor/ " ; //设置FCKeditor路径
$oFCKeditor -> Value = '' ; //设置默认值
$oFCKeditor -> Create () ; //创建。注意：若用到模板（如smarty）则$fck = $oFCKeditor->CreateHtml();然后把$fck抛给模板
?>
<input type="submit" value="提交">
</form>
</body>
</html>

JS用alert( FCKeditorAPI.GetInstance('FCKeditor1').GetXHTML( true ))得到FCKeditor1的值；
PHP用$_POST['FCKeditor1']得到FCKeditor1的值。
