How to use kindeditor extension in YII

YII如何使用kindeditor扩展？本文主要介绍了YII视图整合kindeditor扩展的方法，较为详细的分析了Yii框架整合kindeditor的功能实现代码与设置相关技巧，需要的朋友可以参考下。希望对大家有所帮助。

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，

KEditor代码

<?php
class KEditor extends CWidget{
  /*
   * TEXTAREA输入框的属性，保证js调用KE失败时，文本框的样式。
   */
  public $textareaOptions=array();
  /*
   * 编辑器属性集。
   */
  public $properties=array();
  /*
   * TEXTAREA输入框的name，必须设置。
   * 数据类型：String
   */
  public $name;
  /*
   * TEXTAREA的id，可为空
   */

}

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 $this->widget(&#39;ext.KEditor.KEditor&#39;,array(
  &#39;model&#39;=>$model, //传入form model
  &#39;name&#39;=>&#39;content&#39;, //设置name
  &#39;properties&#39;=>array(
    //设置接收文件上传的action
    &#39;uploadJson&#39;=>&#39;/admin/default/upload&#39;,
    //设置浏览服务器文件的action，这两个就是上面配置在/admin/default的
    &#39;fileManagerJson&#39;=>&#39;/admin/default/manageJson&#39;,
    &#39;newlineTag&#39;=>&#39;br&#39;,
    &#39;allowFileManager&#39;=>true,
    //传值前加js:来标记这些是js代码
    &#39;afterCreate&#39;=>"js:function() {
        K(&#39;#ChapterForm_all_len&#39;).val(this.count());
        K(&#39;#ChapterForm_word_len&#39;).val(this.count(&#39;text&#39;));
      }",
    &#39;afterChange&#39;=>"js:function() {
        K(&#39;#ChapterForm_all_len&#39;).val(this.count());
        K(&#39;#ChapterForm_word_len&#39;).val(this.count(&#39;text&#39;));
      }",
  ),
  &#39;textareaOptions&#39;=>array(
    &#39;style&#39;=>&#39;width:98%;height:400px;&#39;,
  )
));
?>

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'));
  }
});
