禁用的表单元素可以与启用的表单元素共享一列吗？
我有一个表单，其中包含4组组合框，这些组合框填充有另一个表中的数据，并且仅在进行某些选择时才可见且处于活动状态，每组cobobox都包含4个可能的选项集，其中一个或一个都不可见且处于活动状态一次，我已将每组组合框设置为保存到同一表列，因为在任何时候都将只有一个组合框正在工作，因此每组选项的4个单独的列在过滤数据时会太复杂（在我的至少要介意）。
我遇到的问题是我将空值保存到数据库表中，而不是选择的值中，我将代码放在下面以帮助解释我要做什么。

<option value="Cellmark">Cellmark</option>
<option value="DNA Legal">DNA Legal</option>
<option value="The Doctors Lab">The Doctors Lab</option>
</select>
将保存到数据库的选择
<option selected >Select Sample Type</option>
<?php
$connection = mysqli_connect("", "", "", "");
$results = mysqli_query($connection, "SELECT SampleType, LabFee, LabFeeExtra FROM `sampletypes` WHERE Lab = 'Alpha Bio Labs'");
mysqli_close($connection);
foreach($results as $user): ?>
<option value="<?= $user['SampleType']; ?>">
<?= $user['SampleType']; ?>
</option>
<?php endforeach; ?>
</select>
php编码以保存到数据库
$LaborDept = $_POST['Lab1'];
$SampleType1 = $_POST['Samp1'];
$SampleType1 = $_POST['Samp2'];
$SampleType1 = $_POST['Samp3'];
$SampleType1 = $_POST['Samp4'];
$Segmented1 = $_POST['SegmCol1'];
$LaborDept2 = $_POST['Lab2'];
$SampleType2 = $_POST['Samp5'];
$SampleType2 = $_POST['Samp6'];
$SampleType2 = $_POST['Samp7'];
$SampleType2 = $_POST['Samp8'];
$Segmented2 = $_POST['SegmCol2'];
$LaborDept3 = $_POST['Lab3'];

$SampleType4 = $_POST['Samp14'];
$SampleType4 = $_POST['Samp15'];
$SampleType4 = $_POST['Samp16'];
$SegmentedCollection = $_POST['SegmCol'];
$Decleration = $_POST['Decl'];
mysqli_query($connection, "INSERT INTO `collectsamp`(`SampleID`, `LaborDept`, `NumberofSamples`, `SampleType1`, `Segmented1`, `LaborDept2`, `SampleType2`, `Segmented2`, `LaborDept3`, `SampleType3`, `Segmented3`, `LaborDept4`, `SampleType4`, `SegmentedCollection`, `Decleration`) VALUES ('$LabID', '$LaborDept', '$NumberofSamples', '$SampleType1', '$Segmented1', '$LaborDept2', '$SampleType2', '$Segmented2', '$LaborDept3', '$SampleType3', '$Segmented3', '$LaborDept4', '$SampleType4', '$SegmentedCollection', '$Decleration')");
任何帮助将不胜感激

我已经通过重新制作组合框并调整代码以使其与下面的代码段相匹配来解决它；
$SampleType4 = $_POST['Samp13'] . " " . $_POST['Samp14'] . " " . $_POST['Samp15'] . " " . $_POST['Samp16'];
