帝国CMS 给TAG添加首字母自动获取首字母

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：,TAG首字母:,” size=”42″>,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];,},}, , ,
