YII视图整合kindeditor扩展的方法

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，

KEditor代码

  /*
   * TEXTAREA输入框的name，必须设置。
   * 数据类型：String
   */
  public $name;
  /*
   * TEXTAREA的id，可为空
   */

?>

KEditorUpload代码

<?php
class KEditorUpload extends CAction{
  public function run(){
    $dir=isset($_GET['dir'])?trim($_GET['dir']):'file';
    $ext_arr = array(
      'image' => array('gif', 'jpg', 'jpeg', 'png', 'bmp'),
      'flash' => array('swf', 'flv'),
      'media' => array('swf', 'flv', 'mp3', 'wav', 'wma', 'wmv', 'mid', 'avi', 'mpg', 'asf', 'rm', 'rmvb'),
      'file' => array('doc', 'docx', 'xls', 'xlsx', 'ppt', 'htm', 'html', 'txt', 'zip', 'rar', 'gz', 'bz2'),
    );
    if(empty($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');
    Yii::import('ext.KEditor.KEditor');
    $upload_dir=KEditor::getUploadPath().'/'.$dir;
    if(!file_exists($upload_dir)) mkdir($upload_dir);
    $upload_dir=$upload_dir.'/'.$date;
    if(!file_exists($upload_dir)) mkdir($upload_dir);
    $upload_url=KEditor::getUploadUrl().'/'.$dir.'/'.$date;
    if(is_object($upload_image) && get_class($upload_image)==='CUploadedFile'){
      if($upload_image->size > $max_size){
        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;
      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'=>'[e-mail]',
    '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'));
  }
});

希望本文所述对大家基于Yii框架的PHP程序设计有所帮助。
