while($res=mysql_fetch_assoc($query)){ 
$sub=$res['attribute']; 
$sqlfilter="select * from categorywithfilter where attribute='$sub' "; 
$queryfilter=mysql_query($sqlfilter); 

echo " <div class='form-group'> 
      <label class='col-sm-2 control-label'>$sub</label> 
      <div class='col-sm-6'> 

       <select name='category' class='form-control' id='filter'>

        echo'ok';

Answer 3

그냥 변수를 만들 시도하고 필요한 출력을 추가 유지 .

다음과 같이 결과를 인쇄하십시오.

$output = "" 

while($resf=mysql_fetch_assoc($queryfilter)){ 

$output .= " div and other html tags "; 

     /*Append whatever you want*/ 


$output .= " /div"; 

} 

echo $output;

당신은 사용할 수 없습니다 동안 wcho 루프하지만 이런 식으로 뭔가를 할 수 있습니다.

<?php 

    $sql="select distinct(attribute) from categorywithfilter where subcategory='$cat'"; 
    $query=mysql_query($sql); 

    while($res=mysql_fetch_assoc($query)){ 

     $sub=$res['attribute']; 
     $sqlfilter="select * from categorywithfilter where attribute='$sub' "; 
     $queryfilter=mysql_query($sqlfilter); 

?> 
      <div class='form-group'> 
       <label class='col-sm-2 control-label'>$sub</label> 
       <div class='col-sm-6'> 
        <select name='category' class='form-control' id='filter'> 

     <?php 
        while($resf=mysql_fetch_assoc($queryfilter)){ 
         echo'ok'; # wrap ok with option tag 
        } 
     ?> 

        </select> 
       </div> 
       </div> 
<?php 

    } 

?>
