类别和子类别

我有类别和子类别的问题。我不能得到类别相同的category_id子类别的数据。如何我定义的子类别CATEGORY_ID是相同类别CATEGORY_ID和子类别父为2类别和子类别

<?php 
 
//connect to Mysql database 
 
include "storescripts/connect_to_mysql.php"; 
 
// This block grabs the whole list for viewing 
 
$dynamic_menu = ""; 
 
$sql = mysql_query("SELECT * FROM `category` WHERE `parent` IS NULL ORDER BY `category`.`name` ASC"); 
 
$productCount = mysql_num_rows($sql); // count the output amount 
 
if ($productCount > 0) 
 
\t { 
 
\t while($row = mysql_fetch_array($sql)){ 
 
\t \t \t $id = $row["id"]; 
 
\t \t \t $name = $row["name"]; 
 
\t \t \t $parent = $row["parent"]; 
 
\t \t \t $category_id = $row["category_id"]; 
 
\t \t \t $dynamic_menu .= '<div class="menu-primary"> 
 
       <li><a>'.$name.'</a></li></div> 
 
\t \t \t \t <div class="menu-under"> 
 
      <li><a>'.$name.'</a></li> 
 
     </div>'; 
 

 
}} else { 
 
\t $dynamic_menu = "You have no products listed in our store yet"; 
 
} 
 
?>

<div class="menu"> 
 
    <?php echo $dynamic_menu; ?> 
 
</div> 
 

 

 
<!-- 
 

 
I'd like to html created like below 
 

 
<div class="menu-primary"> 
 
     \t <li><a>Kaamerad</a></li> 
 
     </div> 
 
     <div class="menu-under"> 
 
     \t <ul> 
 
      <li><a>optikad</a></li> 
 
      <li><a>mälukaardid</a></li> 
 
      </ul> 
 
     </div>
