1.引入Ueditor 

 1     <!-- 实例化编辑器 -->
 2     <script type="text/javascript">
 3         window.UEDITOR_HOME_URL ="/Data/ueditor/";
 4         window.onload=function(){
 5             window.UEDITOR_CONFIG.initialFrameHeight=300;    
 6             //window.UEDITOR_CONFIG.initialFrameWidth=1000;
 7             UE.getEditor(content);
 8         }
 9     </script>
10     <!-- 配置文件 -->
11     <script type="text/javascript" charset="utf-8" src="/Data/ueditor/ueditor.config.js"></script>
12     <!-- 编辑器源码文件 -->
13     <script type="text/javascript" charset="utf-8" src="/Data/ueditor/ueditor.all.js"> </script>

2.加入水印处理类 (随便找了一个)

  1 <?php
  2 /** 
  3  * 加水印类,支持文字图片水印的透明度设置、水印图片背景透明。
  4  * 日期:2011-09-27
  5  * 作者:www.jb51.net
  6  * 使用:
  7  * $obj = new WaterMask($imgFileName); //实例化对象
  8  * $obj->$waterType = 1; //类型:0为文字水印、1为图片水印
  9  * $obj->$transparent = 45; //水印透明度
 10  * $obj->$waterStr = ‘www.jb51.net‘; //水印文字
 11  * $obj->$fontSize = 16; //文字字体大小
 12  * $obj->$fontColor = array(255,0255); //水印文字颜色(RGB)
 13  * $obj->$fontFile = = ‘AHGBold.ttf‘; //字体文件
 14  * $obj->output(); //输出水印图片文件覆盖到输入的图片文件
 15  */

133         $this->water_im = imagecreatetruecolor($w, $h);
134         imagealphablending($this->water_im, false);
135         imagesavealpha($this->water_im, true);

151             $this->waterimginfo();
152             $this->waterimg();
153         }
154         switch ($this->srcImg_info[2]) {
155             case 3:
156                 imagepng($this->im, $this->srcImg);

167         }
168         imagedestroy($this->im);
169         imagedestroy($this->water_im);
170     }
171 }
172 ?>

3.在项目的Applacation 中添加config.json 文件 进行对添加水印配置:

 1 /* 前后端通信相关的配置,注释只允许使用多行方式 */
 2 {
 3     "waterType":1,/*类型:0为文字水印、1为图片水印*/
 4     "waterImg":"http://127.0.0.8/data/Logo/Logo.png",/*水印图片*/
 5     "waterStr":"www.smartop.xyz",/*水印文字*/
 6     "fontSize":16,/*文字字体大小*/
 7     "fontColor":[0,0,0],/*水印文字颜色(RGB)*/
 8     "fontFile":"./../../Font/ebrimabd.ttf",/*字体文件*/
 9     "transparent":45,/*水印透明度*/
10     "pos":7,/*水印位置支持 1 2 3 4 5 6 7 8 9  九宫格*/ 
11     "imagePathFormat": "/upload/{yyyy}{mm}{dd}/{time}{rand:6}" /* 上传保存路径,可以自定义保存路径和文件名格式 */
12                                 /* {filename} 会替换成原文件名,配置这项需要注意中文乱码问题 */
13                                 /* {rand:6} 会替换成随机数,后面的数字是随机数的位数 */
14                                 /* {time} 会替换成时间戳 */
15                                 /* {yyyy} 会替换成四位年份 */
16                                 /* {yy} 会替换成两位年份 */
17                                 /* {mm} 会替换成两位月份 */
18                                 /* {dd} 会替换成两位日期 */
19                                 /* {hh} 会替换成两位小时 */
20                                 /* {ii} 会替换成两位分钟 */
21                                 /* {ss} 会替换成两位秒 */
22                                 /* 非法字符 \ : * ? " < > | */
23                                 /* 具请体看线上文档: fex.baidu.com/ueditor/#use-format_upload_filename */
24 }

4.修改controller.php入口文件

将自己的config.json自己的配置加入到配置里面

1 $CONFIG = json_decode(preg_replace("/\/\*[\s\S]+?\*\//", "", file_get_contents("config.json")), true);
2 $SELFCONFIG = json_decode(preg_replace("/\/\*[\s\S]+?\*\//", "", file_get_contents("./../../../../Application/Conf/config.json")), true);
3 $CONFIG =  array_merge($CONFIG,$SELFCONFIG);

5.配置:action_upload.php 将自定义配置项写入:

1             "waterType" => $CONFIG[‘waterType‘],
2             "waterImg" => $CONFIG[‘waterImg‘],
3             "waterStr" => $CONFIG[‘waterStr‘],
4             "fontSize" => $CONFIG[‘fontSize‘],
5             "fontColor" => $CONFIG[‘fontColor‘],
6             "fontFile" => $CONFIG[‘fontFile‘],
7             "transparent" => $CONFIG[‘transparent‘],
8             "pos" => $CONFIG[‘pos‘],

6.配置:Uploader.class.php 增加一个水印处理的私有方法:

 1     /**
 2      * 添加水印
 3      */
 4     private function water(){
 5         require_once(‘Water.class.php‘);
 6         $obj = new WaterMask($this->filePath); //实例化对象
 7         if($this->config[‘waterType‘]){
 8             $obj->waterType = $this->config[‘waterType‘];
 9             $obj->waterImg = $this->config[‘waterImg‘]; //水印图片
10         }else{
11             $obj->waterType = $this->config[‘waterType‘];
12             $obj->waterStr = $this->config[‘waterStr‘];//水印文字
13             $obj->fontSize = $this->config[‘fontSize‘]; //文字字体大小
14             $obj->fontColor = $this->config[‘fontColor‘]; //水印文字颜色(RGB)
15             $obj->fontFile = $this->config[‘fontFile‘]; //字体文件 
16         }
17         $obj->transparent = $this->config[‘transparent‘]; //水印透明度
18         $obj->pos = $this->config[‘pos‘]; //水印位置
19         $obj->output(); //输出水印图片文件覆盖到输入的图片文件
20     }
