问题是，如果数据位于第二个名为locationstbl的表中，并且该表在sql中的地址为列，那么如何在模态内检索Locatie（下拉列表）的数据。
也许有某种方式可以使用JOIN或类似的方式来显示我在该下拉列表中需要的数据？
谢谢。
这是代码。
<table class="table table-bordered" id="dataTable" width="100%" cellspacing="0">
<thead>
<tr>
<th>#</th>
<th>Locatie</th>
<th>Serie Aparat</th>
<th>Tip Joc</th>
<th>Cabinet</th>
<th>Data Expirare</th>
<th>Actiuni</th>
</tr>
</thead>
<tbody>
<?php
$sql = "SELECT location, serial, game_type, cabinet, date
FROM all_machines
ORDER BY location ASC";
$result = $conn->query($sql);
$resultNum = mysqli_num_rows($result);
$counter = 1;
if ($resultNum > 0) {
while ($row = mysqli_fetch_assoc ($result)){
$location = $row['location'];
$serial = $row['serial'];
$game_type = $row['game_type'];
$cabinet = $row['cabinet'];
$date = $row['date'];
?>

答案 0 :(得分：1)
在给出可能的答案之前，我想提醒您开始考虑采用PHP开发框架并充分利用其优势。从长远来看，将PHP与HTML混合使用会适得其反，并且难以维护。 您有两种方法可以做到：
$locaties = "SELECT * FROM locationstbl"
通过此解决方案，您所在的下拉菜单将如下所示：<div class='col-md-6'>
<label>Locatie</label>
<select name='location' class='form-control input-sm'>
<?php foreach($locaties as $locatie){ ?>
<option><?php echo $locatie ?></option>
<?php } ?>
</select>
<span class='help-block'></span>
</div>
