 $query = "SELECT .... ";
 if($result = mysql_query($query)){
     while($row = mysql_fetch_assoc($result)){
          //...
     }
 } else {
     echo mysql_error();
 }

エラーを出力する必要があることに加えて、少なくとも mysqli を使用する必要があります。mysql_* 関数は非推奨であり、PHP 5.5 で削除されます。

クエリを実行していません。

while ループの前に追加$result = mysql_query($query)し、ループテストを次のように変更します。$row = mysql_fetch_assoc($result)

また、mysql_* 関数は推奨されておらず、PHP の将来の更新で削除される予定です。mysqli_* または PDO に切り替えます。

個人的にはPDOをお勧めします。

$query = mysql_query("SELECT...") or die(mysql_error());
if ($query){
while($row = mysql_fetch_assoc($query)){
// Do something
}
}

これを試してください

if(mysql_num_rows($query) > 0){

   while($row = mysql_fetch_assoc($query)){
   // Do something
   }
}
else{
    echo "No record found";
}
