自己获取TAG首字母教程

第一步：在表enewstags增加字段zm(建议用phpmyadmin或直接SQL:

ALTER TABLE `phome_enewstags` ADD `zm` CHAR(2) NOT NULL AFTER `tagname`;)

——————————

第二步：

找到 eadmintagsAddTags.php

查找：$r=$empire->fetch1("select tagid,tagname,cid from {$dbtbpre}enewstags where tagid='$tagid'");

修改为：$r=$empire->fetch1("select tagid,tagname,zm,cid from {$dbtbpre}enewstags where tagid='$tagid'");

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：eadmintagsListTags.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 >= -18710 and $asc <= -18527) return "E";

if($asc >= -18526 and $asc <= -18240) return "F";

if($asc >= -18239 and $asc <= -17923) return "G";

if($asc >= -17922 and $asc <= -17418) return "I";

if($asc >= -17417 and $asc <= -16475) return "J";

if($asc >= -16474 and $asc <= -16213) return "K";

if($asc >= -16212 and $asc <= -15641) return "L";

if($asc >= -15640 and $asc <= -15166) return "M";

if($asc >= -15165 and $asc <= -14923) return "N";

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['9']='9';

   $numstr['一']='1';

   $numstr['二']='2';

   $numstr['三']='3';

   $numstr['四']='4';

   $numstr['五']='5';

   $numstr['六']='6';

   $numstr['七']='7';

   $numstr['八']='8';

   $numstr['九']='9';

   if(strstr($numstrs,$s0))

   {

   return $numstr[$s0];

   }

}
