Return the exact ID using fetch_assoc

Question

I have a small problem in my code. I'm using fetch_assoc to get data from database and I need to get the ID number of each of returned values. the issue is that my code only return the ID number of the last data. Here's my code:

<form method="post" action="action.php">
  
  <select name="album" style="border:1px solid #CCC; font-size:11px; padding:1px">
      
       <?php

          $sql = "SELECT * FROM table";
          $stmt = $dbh -> prepare($sql);
          $stmt -> execute();
          
          while($row = $stmt -> fetch(PDO::FETCH_ASSOC))
          {
 
            $album_ID = $row['album_ID'];
            $value = $row['album_name'];         
            print "<option value ='". $value ."'>". $value. "</option>";


          }

       ?>
  
  </select>
  <input type="hidden" name="album_ID" value="<?php print $album_ID?>"/>
</form>

I would like the hidden input type holds the selected album id, but it always holds the album id of the last data.

Answer 1

Your best bet would be to place the id in the value od the option

....
while($row = $stmt -> fetch(PDO::FETCH_ASSOC))
{

    $album_ID = $row['album_ID'];
    $value = $row['album_name'];         
    print "<option value ='". $album_ID ."'>". $value. "</option>";


}

....

Then on the submission script (admin.php) the POST variable album will contain the ID, there is no need for the hidden input
