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

<?php

  /*
   * 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。
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"));
  }
});
