如何存储多个复选框，如果它们是动态的在php

Question

您好，我试图将多个选定的值存储在一个新的表中最后插入的ID。

我的错误是数组来了，但id_facility值不来

这里是我的形式：

<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> 

我想在新表中的列存储的id_hostel，id_facility

我的形式：

<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> 

这里是存储作业后，我的控制器页：

$hostelId=$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."')"); 
}
