织梦dedecms联动菜单通过evalue获取三级所有的ename的内容(联动三级的换算方程式) ，
//参数$evalue联动的值$egroup联动的别名 。
//获得联动全部内容：
function ed_get_enum($evalue,$egroup){ global $db; //获取小数点后的数值 $fr=explode(".",$evalue); //判断联动等级 //判断是否整除500(是则为一级联动) if($evalue%500=='0') { $rs_top=$db->getOne("select * from dede_sys_enum where evalue='$evalue' and egroup='$egroup'"); $ename_top = $rs_top[ename]; } //判断能否整除500 并且没有小数点(是则为二级联动) if($evalue%500!='0' && $fr[1]=='') { $rs_son=$db->getOne("select * from dede_sys_enum where evalue='$evalue' and egroup='$egroup'"); $ename_son = $rs_son[ename]; //换算一级联动 $evalue_top = $evalue-($evalue%500); $rs_top=$db->getOne("select * from dede_sys_enum where evalue='$evalue_top' and egroup='$egroup'"); $ename_top = $rs_top[ename]; } //判断小数点后是否有值(有值则为三级联动) if($fr[1]!='') { $rs_sec=$db->getOne("select * from dede_sys_enum where evalue='$evalue' and egroup='$egroup'"); $ename_sec = $rs_sec[ename]; //换算二级联动 //获取小数点前的数值 $evalue_son = $fr[0]; $rs_son=$db->getOne("select * from dede_sys_enum where evalue='$evalue_son' and egroup='$egroup'"); $ename_son = $rs_son[ename]; //换算一级联动 $evalue_top =$evalue_son-($evalue_son%500); $rs_top=$db->getOne("select * from dede_sys_enum where evalue='$evalue_top' and egroup='$egroup'"); $ename_top = $rs_top[ename]; } //返回联动 return $ename_top." ".$ename_son." ".$ename_sec; } 使用方法 {dede:php} //联动的evalue值,联动的字段 echo ed_getSelect('500','nativeplace'); {/dede:php} [field:nativeplace function="ed_getSelect(@me,'nativeplace')"/]
