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]; }}
