在69行后添加：
<tr bgcolor="#FFFFFF">        
<td width="18%" height="25">TAG首字母:</td>        
<td width="82%" height="25"> <input name="zm" type="text" id="zm" value="<?=$r[zm]?>" size="42">         </td>      
</tr>

第三步：
修改文件：/e/admin/tags/ListTags.php
——————————————————————–
require(“../../class/userfun.php”);
查找：$tagname=RepPostVar($add[‘tagname’]);
202行后增加：$tagzm=getfirstchar(RepPostVar($_POST[‘tagname’]));
——————————————————————–
查找：//修改TAGS 函数里添加：$zm=RepPostVar($add[‘zm’]);
查找：$sql=$empire->query(“insert into {$dbtbpre}enewstags(tagname,num,isgood,cid) values(‘$tagname’,0,0,’$cid’);”);
修改为：$sql=$empire->query(“insert into {$dbtbpre}enewstags(tagname,num,zm,isgood,cid) values(‘$tagname’,0,’$tagzm’,0,’$cid’);”);
—————————————————————————————————————————
查找：$sql=$empire->query(“update {$dbtbpre}enewstags set tagname=’$tagname’,cid=’$cid’ where tagid=’$tagid'”);
修改为：$sql=$empire->query(“update {$dbtbpre}enewstags set tagname=’$tagname’,cid=’$cid’,zm=’$zm’ where tagid=’$tagid'”);
第四步：
打开/e/class/userfun.php
添加函数：
function getfirstchar($s0){      
$fchar = ord($s0{0});    
if($fchar >= ord("A") and $fchar <= ord("z") )return strtoupper($s0{0});    
$s1 = iconv("UTF-8","gb2312", $s0);    
$s2 = iconv("gb2312","UTF-8", $s1);    
if($s2 == $s0){
$s = $s1;
}else{
$s = $s0;
}    
$asc = ord($s{0}) * 256 + ord($s{1}) - 65536;    
if($asc >= -20319 and $asc <= -20284) return "A";    
if($asc >= -20283 and $asc <= -19776) return "B";    
if($asc >= -19775 and $asc <= -19219) return "C";    
if($asc >= -19218 and $asc <= -18711) return "D";

if($asc >= -14922 and $asc <= -14915) return "O";    
if($asc >= -14914 and $asc <= -14631) return "P";    
if($asc >= -14630 and $asc <= -14150) return "Q";    
if($asc >= -14149 and $asc <= -14091) return "R";    
if($asc >= -14090 and $asc <= -13319) return "S";    
if($asc >= -13318 and $asc <= -12839) return "T";    
if($asc >= -12838 and $asc <= -12557) return "W";    
if($asc >= -12556 and $asc <= -11848) return "X";    
if($asc >= -11847 and $asc <= -11056) return "Y";    
if($asc >= -11055 and $asc <= -10247) return "Z";    
if(!trim($s0))       {          
return null;      
}      
$s0=esub($s0,1);      
$numstrs='123456789一二三四五六七八九';      
$numstr['1']='1';      
$numstr['2']='2';      
$numstr['3']='3';      
$numstr['4']='4';      
$numstr['5']='5';      
$numstr['6']='6';      
$numstr['7']='7';      
$numstr['8']='8';

$numstr['八']='8';      
$numstr['九']='9';      
if(strstr($numstrs,$s0))       {      
return $numstr[$s0];      
}
