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')"/]
