PHP 필터 및 분 단위로 정렬

Question

php 및 mysql을 사용하여 디스플레이 패키지 페이지를 만들었습니다. 출력물을 다시보기 위해 10 개의 버튼이 테이블 위에 있습니다. 내가 refilter를 어떻게 사용했는지는 $_GET['command']이고 이는 'AND lock_in_period = '1yr''과 같습니다. $_GET['command']을 세션 아래에 저장하려고했지만 작동하지 않습니다. 문제는 지금 내가 출력을 refilter 후 오름차순 또는 desc 정렬 분 대출 금액을 얻을 수 없다는 것입니다.

MySQL의 쿼리

if($property_type_search == 'HDB'){ 
    $find=mysql_query("SELECT*FROM package_creation WHERE property_type IN ('HDB','HDB,Private') $newcommand ORDER BY $columnname $order"); 
} 

분 대출금 정렬 버튼 :

<a class="link_style" href="<?php echo $_SERVER['PHP_SELF']; ?>?command=<?php echo $_GET['command']?>&columnname= min_loan_amount&<?php if($_GET['sort']== "asc"){echo "sort=desc"; $_GET['sort']="asc";}elseif($_GET['sort']=="desc"){echo "sort=asc";$_GET['sort']="desc";}elseif($_GET['sort']==""){echo "sort=asc";}?>"><img src="images/arrow_sort.png"></a>
