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='$tagid'");
第四步：
打开/e/class/userfun.php
添加函数：
001 | function getfirstchar($s0){ |
005 | if($fchar >= ord("A") and $fchar <= ord("z") )return strtoupper($s0{0}); |
007 | $s1 = iconv("UTF-8","gb2312", $s0); |
009 | $s2 = iconv("gb2312","UTF-8", $s1); |
011 | if($s2 == $s0){$s = $s1;}else{$s = $s0;} |
013 | $asc = ord($s{0}) * 256 + ord($s{1}) - 65536; |
015 | if($asc >= -20319 and $asc <= -20284) return "A"; |
017 | if($asc >= -20283 and $asc <= -19776) return "B"; |
019 | if($asc >= -19775 and $asc <= -19219) return "C"; |
021 | if($asc >= -19218 and $asc <= -18711) return "D"; |
023 | if($asc >= -18710 and $asc <= -18527) return "E"; |
025 | if($asc >= -18526 and $asc <= -18240) return "F"; |
027 | if($asc >= -18239 and $asc <= -17923) return "G"; |
029 | if($asc >= -17922 and $asc <= -17418) return "I"; |
031 | if($asc >= -17417 and $asc <= -16475) return "J"; |
033 | if($asc >= -16474 and $asc <= -16213) return "K"; |
035 | if($asc >= -16212 and $asc <= -15641) return "L"; |
037 | if($asc >= -15640 and $asc <= -15166) return "M"; |
039 | if($asc >= -15165 and $asc <= -14923) return "N"; |
041 | if($asc >= -14922 and $asc <= -14915) return "O"; |
043 | if($asc >= -14914 and $asc <= -14631) return "P"; |
045 | if($asc >= -14630 and $asc <= -14150) return "Q"; |
047 | if($asc >= -14149 and $asc <= -14091) return "R"; |
049 | if($asc >= -14090 and $asc <= -13319) return "S"; |
051 | if($asc >= -13318 and $asc <= -12839) return "T"; |
053 | if($asc >= -12838 and $asc <= -12557) return "W"; |
055 | if($asc >= -12556 and $asc <= -11848) return "X"; |
057 | if($asc >= -11847 and $asc <= -11056) return "Y"; |
059 | if($asc >= -11055 and $asc <= -10247) return "Z"; |
071 | $numstrs='123456789一二三四五六七八九'; |
109 | if(strstr($numstrs,$s0)) |
