本文实例讲述了yii视图整合kindeditor扩展的方法。分享给大家供大家参考，具体如下：
比较喜欢用kindeditor,yii上的版本比较旧,所以自己重新整了个扩展
先在protectedextensions下创建keditor文件夹用来放文件，kesource里放kindeditor的源文件，然后建三个类keditor、keditormanage和keditorupload，keditor是扩展的主文件，keditormanage是用来浏览服务器文件的，keditorupload是用来示例接收上传文件的，
keditor代码

keditorupload代码

if(empty($ext_arr[$dir])){
echo cjson::encode(array('error'=>1,'message'=>'目录名不正确。'));
exit;
}
$originalurl='';
$filename='';
$date=date('ymd');
$id=0;
$max_size=2097152; //2mbs
$upload_image=cuploadedfile::getinstancebyname('imgfile');

exit;
}
//新文件名
$filename=date("ymdhis").'_'.rand(10000, 99999);
$ext=$upload_image->extensionname;
if(in_array($ext, $ext_arr[$dir]) === false){
echo cjson::encode(array('error'=>1,'message'=>"上传文件扩展名是不允许的扩展名。n只允许".implode(',',$ext_arr[$dir]).'格式。'));
exit;
}
$uploadfile=$upload_dir.'/'.$filename.'.'.$ext;
$originalurl=$upload_url.'/'.$filename.'.'.$ext;
$upload_image->saveas($uploadfile);
echo cjson::encode(array('error'=>0,'url'=>$originalurl));
}else{
echo cjson::encode(array('error'=>1,'message'=>'未知错误'));
}
}
}
配置config/main.php文件，设置上传文件存放位置
'params'=>array(
// this is used in contact page
'adminemail'=>'webmaster@example.com',
'uploadpath'=>'/upload', //添加这句，upload为存放文件文件夹的名字，自己定义，这里是放在根目录的upload文件夹
设置接收文件和浏览服务器文件的action
public function actions()
{
return array(
//在actions下的return array添加下面两句，没有actions的话自己添加
'upload'=>array('class'=>'application.extensions.keditor.keditorupload'),
'managejson'=>array('class'=>'application.extensions.keditor.keditormanage'),
);
}
在视图里面使用
<?php $this->widget('ext.keditor.keditor',array(
'model'=>$model, //传入form model
'name'=>'content', //设置name
'properties'=>array(
//设置接收文件上传的action
'uploadjson'=>'/admin/default/upload',
//设置浏览服务器文件的action，这两个就是上面配置在/admin/default的
'filemanagerjson'=>'/admin/default/managejson',
'newlinetag'=>'br',
'allowfilemanager'=>true,
//传值前加js:来标记这些是js代码
'aftercreate'=>"js:function() {
k('#chapterform_all_len').val(this.count());
k('#chapterform_word_len').val(this.count('text'));
}",
'afterchange'=>"js:function() {
k('#chapterform_all_len').val(this.count());
k('#chapterform_word_len').val(this.count('text'));
}",
),
'textareaoptions'=>array(
'style'=>'width:98%;height:400px;',
)
));
?>
textareaoptions用来设置textarea的大小和样式，仅支持rows、cols和style
properties的各项跟js设置kindeditor的是一样的，上面的设置与下面用js设置的是一致，kindeditor原来有的项都可以设置
var editor1 = k.create('#editor_modelname_name', {
uploadjson : "/admin/default/upload",
filemanagerjson : "/admin/default/managejson",
newlinetag : "br",
allowfilemanager : true,
aftercreate : function() {
k('#chapterform_all_len').html(this.count());
k('#chapterform_word_len').html(this.count('text'));
},
afterchange : function() {
k('#chapterform_all_len').html(this.count());
k('#chapterform_word_len').html(this.count('text'));
}
});
