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protected\extensions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,

        echo cjson::encode(array('error'=>1,'message'=>'上传文件大小超过限制。'));
        exit;
      }
      //新文件名
      $filename=date("ymdhis").'_'.rand(10000, 99999);
      $ext=$upload_image->extensionname;

      $upload_image->saveas($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'));
  }
});
