如何存儲多個複選框，如果它們是動態的在php

Question

您好，我試圖將多個選定的值存儲在一個新的表中最後插入的ID。

我的錯誤是數組來了，但id_facility值不來

這裏是我的形式：

<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儲的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> 

這裏是存儲作業後，我的控制器頁：

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