今天大象哥写了个联动类别的查询共享出来
//枚举查询
function get_enum($topvalue,$egroup = 'shoptype'){
global $dsql;//商品枚举
//一级枚举
$orderby = 'ORDER BY disorder ASC, evalue ASC';
if ($topvalue == 'all'){//取全部枚举
$egroupsql = " WHERE egroup LIKE '$egroup'";
} elseif(!$topvalue){//取一级枚举
$egroupsql = " WHERE egroup LIKE '$egroup' AND egroup='$egroup' AND (evalue MOD 500)=0";
} elseif($topvalue % 500 == 0){//取二级枚举
$egroupsql = " WHERE egroup LIKE '$egroup' AND evalue>=$topvalue AND evalue < ".($topvalue + 500);
} else { //取三级枚举
$egroupsql = " WHERE (evalue LIKE '$topvalue.%%%' OR evalue=$topvalue) AND egroup LIKE '$egroup'";
}
$sql = "SELECT * FROM `#@__sys_enum` $egroupsql $orderby";
echo $sql;
}
