问题描述
我正在创建类似程序的购物车，因此在我请求或发送预订请求后，数据将被放置在第二个选项卡上。我已经完成了，但是问题是我需要删除第一个选项卡上的所选数据。这是供视觉参考的图像：
然后选择我的第二个标签
我已经尝试过使用新的Array和Array push，并在Array中使用它，但是仍然出现第一个选项卡数据仍显示的问题，如何隐藏或删除从第一个选项卡中选择的数据？这是我的代码
查看
<?PHP $newArray = array(); ?>
<?PHP foreach($dorms as $dorm): ?>
<?PHP
$res = $dorm['code'];
array_push($newArray,$res);
?>
<a class="text-decoration-none" href="<?PHP echo base_url() ?>pages/view/<?PHP echo $dorm['id']; ?>">
<div class="col-md-6 mt-4" style="margin-left: 6rem;padding-bottom: 1rem;">
<div class="card top-shadow" style="width: 12rem; text-align:center;display:inline-block;">
<div class="card-body">
<img src="<?PHP echo base_url(); ?>assets/images/dorms/<?PHP echo $dorm['image'] ?>" style="border-radius: 15%;width:100px;height:100px;">
<hr class="border-black">
<h5 class="card-title color-black">Room Type: <b><?PHP echo $dorm['type']; ?></b></h5>
<h5 class="card-title color-black">Room Cost: <br><b> P <?PHP echo $dorm['price']; ?>.00</b></h5>
<?PHP if ($dorm['status'] == 0): ?>

第二个标签
<?PHP foreach($dormreserved as $dormres): ?>
<?PHP
$pos = $dormres['code'];
?>
<?PHP if(in_array($pos,$newArray)): ?>
<a class="text-decoration-none" href="<?PHP echo base_url() ?>pages/view/<?PHP echo $dormres['id']; ?>">
<div class="col-md-6 mt-4" style="margin-left: 6rem;padding-bottom: 1rem;">
<div class="card top-shadow" style="width: 12rem; text-align:center;display:inline-block;">
<div class="card-body">
<img src="<?PHP echo base_url(); ?>assets/images/dorms/<?PHP echo $dormres['image'] ?>" style="border-radius: 15%;width:100px;height:100px;">
<hr class="border-black">
<h5 class="card-title color-black">Room Type: <b><?PHP echo $dormres['code']; ?></b></h5>
