供将来参考请注意，option元素具有value属性在提交表格时发送。在这个阶段，你只使用name和innerHTML，这就是为什么表单没有正确发送

<select name='id_alb'>
<?php
    $get ='SELECT * FROM name_alb';
    $run_get = mysqli_query($con,$get);
    while($fetch = mysqli_fetch_array($run_get))
    {
      echo "<option value=".$fetch['id'].">".$fetch['name_alb']."</option>";
    }
?>
</select>
