CKEditor实现图片上传,并且回调图片路径

$app->post(‘/savePic‘,function() use($app){

    $data=\model\Agv::uploadPic();


});

//上传图片
    public static function uploadPic()
    { 
        $file_type=array(‘image/jpg‘,‘image/gif‘,‘image/png‘,‘image/bmp‘,‘image/jpeg‘);//文件类型
        $max_size=‘1048576‘;      // 最大文件限制（单位：byte）
        $upload_path=‘./attached/img‘.date("Ym").‘/‘; //图片目录路径

        $file=$_FILES[‘upload‘];  
        if (!is_dir($upload_path)) {    //判断存放文件目录是否存在
            mkdir($upload_path,0777,true);
        }
        if(!is_uploaded_file($file[‘tmp_name‘])){ //判断上传文件是否存在tmp_name
            $rs[‘message‘] = 2;//上传文件不存在
            return $rs;
        }
        if($file[‘size‘]>$max_size){  //判断文件大小是否大于500000字节
            $rs[‘message‘] = 3;//上传文件大
            return $rs;
        } 
        if(!in_array($file[‘type‘],$file_type)){  //判断图片文件的格式
            $rs[‘message‘] = 4;//上传文件格式不对
            return $rs;
        }

        $img = $image_size[0].‘*‘.$image_size[1];
        $name = $file[‘name‘];
        $fname = explode(‘.‘, $name);
        $pic_path = $upload_path.date("YmdHis").rand(100,999).".".$fname[1]; 
        if(file_exists($pic_path)){

        }
            
        $rs[‘path‘] = substr($pic_path, 1);
        //回调函数 返回图片预览
        $callback = $_REQUEST["CKEditorFuncNum"];    
        echo "<script type=‘text/javascript‘>window.parent.CKEDITOR.tools.callFunction($callback,‘".$pic_path."‘,‘‘);</script>";

	config.image_previewText=‘ ‘; //预览区域显示内容
