如果它们在php中是动态的，如何存储多个复选框

Question

嗨我正在尝试将多个选定值存储在最后插入id的新表中。

  

我的错误是数组即将到来，但id_facility值未来

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>

我想在新表列中存储id_hostel，id_facility

Answer 1

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>

这是存储作业后的控制器页面：

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