を使用して、次の数ページにドロップダウンから属性を保つために、私は、ドロップダウン・ページからこのコードを持っています。（すべてではない）

と、このページからオプションを選択した後ユーザーが選択したオプションに基づいてファイルをインポートする必要がドロップダウン...（以下、いくつかのコード）

<center><h4 class="page-header">PEPERIKSAAN : <?php 

     $peperiksaan_nama=$_POST["peperiksaan_id"]; 
     echo $peperiksaan_nama ?> <br> 
     MATAPELAJARAN : Matematik <br> 
     KELAS : <?php 
     $kelas_nama=$_POST['kelas_id']; 
     $darjah_nama=$_POST['darjah_id']; 
      echo $darjah_nama; ?> <?php 
      echo $kelas_nama; ?> <br> 
     TAHUN : <?php $tahun_nama=$_POST['tahun_id']; echo $tahun_nama?> 
    </h4></center> 

<center> <form id="import" name="import" method="post" enctype="multipart/form-data"> 
    <input type="file" name="file" /><br /> 
    <input class="btn btn-primary" type="submit" name="submit" value="Import"/> <br><br> 
</form> </center> 

<?php 

if(isset($_POST["submit"])) 
{ 
    $file = $_FILES['file']['tmp_name']; 
    $handle = fopen($file, "r"); 
    $c = 0; 
    while(($filesop = fgetcsv($handle, 1000, ",")) !== false) 
    { 

     $murid_ic = $filesop[0]; 
     $murid_nama = $filesop[1]; 
     $murid_markah = $filesop[2]; 
     $murid_gred = $filesop[3]; 
     $tahun_id = $filesop[4]; 
     $peperiksaan_id = $filesop[5]; 
     $kelas_id = $filesop[6]; 
     $darjah_id = $filesop[7];  


     $query = query("INSERT INTO murid (murid_ic,murid_nama, murid_markah, murid_gred, tahun_id, peperiksaan_id, kelas_id, darjah_id) 

     VALUES ('$murid_ic','$murid_nama','$murid_markah','$murid_gred','$tahun_id','$peperiksaan_id','$kelas_id','$darjah_id')"); 

     $c = $c + 1; 
    } 

     if($query){ 

      redirect("index.php?pages=peperiksaan2&tahun_id=$tahun_id&peperiksaan_id=$peperiksaan_id&darjah_id=$darjah_id&kelas_id=$kelas_id"); 
       echo "You database has imported successfully. You have inserted ". $c ." recoreds"; 
     }else{ 
      echo "Sorry! There is some problem."; 
     } 

} 
?> 


    <table width="100%" class="table table-striped table-bordered table-hover"> 
     <thead> 
       <tr> 
        <th>BIL</th> 
        <th>NAMA</th> 
        <th>NO IC</th> 
        <th><center>MARKAH</center></th> 
        <th><center>GRED</center></th> 
       </tr> 
       </thead> 

     <?php    

      $bil = 0; 

      $SQLSELECT = "SELECT murid.*, peperiksaan.*, tahun.*, darjah.*, kelas.* FROM murid, peperiksaan, tahun, darjah, kelas WHERE murid.peperiksaan_id = peperiksaan.peperiksaan_id AND murid.tahun_id = tahun.tahun_id AND murid.darjah_id = darjah.darjah_id AND murid.kelas_id = kelas.kelas_id" ; 

      $result_set = mysqli_query($con, $SQLSELECT); 

      while($row = mysqli_fetch_array($result_set)) 
      { 
       $bil++; 
      ?> 

       <tr> 
        <td><?php echo $bil; ?></td> 
        <td><?php echo $row['murid_nama']; ?></td> 
        <td><?php echo $row['murid_ic']; ?></td> 
        <td><center><?php echo $row['murid_markah']; ?></center></td> 
        <td><center><?php echo $row['murid_gred']; ?></center></td>  

       </tr> 


      <?php 
      } 
     ?>    

それはちょうど良いです。しかし、ファイルをインポートした後、属性はもはやオプションから値を読み取ることはありません。なぜそれが起こるのですか？インポートボタンは同じページにつながります。
