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)

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 }
