php - 如果多个复选框在 php 中是动态的，如何存储它们

Question

您好，我正在尝试将多个选定的值存储在具有上次插入的 ID 的新表中。

my error is array is coming but id_facility value is not coming

这是我的表格:

<ul id="hostel_facility" class="dropdown-menu dropdown-select">
    <?php  $facility = $conn->query("SELECT * FROM os_facilities  ORDER BY id_facility ASC");
        while ($facilityresult = $facility->fetch_assoc()) { ?>
        <li><a><input type="checkbox" name="hostel_facility[]" value="<?php  echo$facilityresult['id_facility']; ?>" /><?php echo $facilityresult['facility_name']; ?></a></li>
    <?php } ?>
</ul>

我想存储在新表中的列是 id_hostel、id_facility

我的表格:

<ul id="hostel_facility" class="dropdown-menu dropdown-select">
    <?php  $facility = $conn->query("SELECT * FROM os_facilities  ORDER BY id_facility ASC");
        while ($facilityresult = $facility->fetch_assoc()) { ?>
        <li><a><input type="checkbox" name="hostel_facility[]" value="<?php  echo $facilityresult['id_facility']; ?>" /><?php echo $facilityresult['facility_name']; ?></a></li>
    <?php } ?>
</ul>

这是存储作业后我的 Controller 页面:

$hostelId=$conn->insert_id;
if($addHostel)
{
foreach($hostelData['hostel_facility'] as $key=>$facility)
{
    $conn->query("INSERT INTO os_hostel_facility (id_hostel,id_facility) values ('".$hostelId."','".$facility."')");
}
