几个小小设置把帝国CMS弹窗alert支持json格式输出

几个小小设置可以把帝国弹窗alert支持json格式输出,原来alert弹窗就不见了，不影响原版功能；
虽然这个功能自己几乎不用 ，看到网友经常要处理这个问题，顺手发一个。
1、在要输出json头部代码

1. ------------------------------- 
2. define('API_WORK', true)； 
3. ------------------------------- 

2.改造printerror和printerror2，增加一个参数$statuscode，不写的状态200

1. //错误提示 
2. function printerror($error="",$gotourl="",$ecms=0,$noautourl=0,$novar=0, $statuscode = 200){ 
3.         global $empire,$editor,$public_r,$ecms_config; 
4.         if($editor==1){$a="../";} 
5.         elseif($editor==2){$a="../../";} 
6.         elseif($editor==3){$a="../../../";} 
7.         else{$a="";} 
8.         if($ecms==1||$ecms==9) 
9.         { 
10.                 $a=ECMS_PATH.'e/data/'; 
11.         } 
12.         if(strstr($gotourl,"(")||empty($gotourl)) 
13.         { 
14.                 if(strstr($gotourl,"(-2")) 
15.                 { 
16.                         $gotourl_js="history.go(-2)"; 
17.                         $gotourl="javascript:history.go(-2)"; 
18.                 } 
19.                 else 
20.                 { 
21.                         $gotourl_js="history.go(-1)"; 
22.                         $gotourl="javascript:history.go(-1)"; 
23.                 } 
24.         } 
25.         else 
26.         {$gotourl_js="self.location.href='$gotourl';";} 
27.         if(empty($error)) 
28.         {$error="DbError";} 
29.         if($ecms==9)//前台弹出对话框 
30.         { 
31.                 @include $a.LoadLang("pub/q_message.php"); 
32.                 $error=empty($novar)?$qmessage_r[$error]:$error; 
33.                 
34.                 //修改的
35.                 if(defined('API_WORK') && API_WORK)        throw new Exception($error, '1' . $statuscode); 
36.                 
37.                 echo"<script>alert('".$error."');".$gotourl_js."</script>"; 
38.                 db_close(); 
39.                 $empire=null; 
40.                 exit(); 
41.         } 
42.         elseif($ecms==8)//后台弹出对话框 
43.         { 
44.                 @include $a.LoadLang("pub/message.php"); 
45.                 $error=empty($novar)?$message_r[$error]:$error; 
46.                 
47.                 //修改的 
48.                 if(defined('API_WORK') && API_WORK)        throw new Exception($error, '1' . $statuscode); 
49.                 
50.                 echo"<script>alert('".$error."');".$gotourl_js."</script>"; 
51.                 db_close(); 
52.                 $empire=null; 
53.                 exit(); 
54.         } 
55.         elseif($ecms==7)//前台弹出对话框并关闭窗口 
56.         { 
57.                 @include $a.LoadLang("pub/q_message.php"); 
58.                 $error=empty($novar)?$qmessage_r[$error]:$error; 
59.                 
60.                 //修改的 
61.                 if(defined('API_WORK') && API_WORK)        throw new Exception($error, '1' . $statuscode); 
62.                 
63.                 echo"<script>alert('".$error."');window.close();</script>"; 
64.                 db_close(); 
65.                 $empire=null; 
66.                 exit(); 
67.         } 
68.         elseif($ecms==6)//后台弹出对话框并关闭窗口 
69.         { 
70.                 @include $a.LoadLang("pub/message.php");

90.                 $error=empty($novar)?$qmessage_r[$error]:$error; 
91.                 
92.                 //修改的
93.                 if(defined('API_WORK') && API_WORK)        throw new Exception($error, '1' . $statuscode); 
94.                 
95.                 @include($a."../message/index.php"); 
96.         } 
97.         db_close(); 
98.         $empire=null; 
99.         exit(); 
100. } 

1. //错误提示2：直接文字 
2. function printerror2($error='',$gotourl='',$ecms=0,$noautourl=0, $statuscode = 200){ 
3.         global $empire,$public_r; 
4.         if(strstr($gotourl,"(")||empty($gotourl)) 
5.         {

39. } 

3、使用自动加载功能和异常处理。以上3个步骤完成，一起来体验吧！
技巧：define('API_WORK', true)；可以改为动态的，不是新写的文件时还有必要，传一下$_GET['json'] = 1就样就可以解决了

1. define('API_WORK', isset($_GET['json'])); 

这个就可以原代码一个不动了
