由于您不了解Ajax，您可以这样做：
1） 重置$result数组，再次为MySQL查询选择项。
2） 使用while循环将每个选定值插入数据库


reset($result);
while($row=mysqli_fetch_array($result))
{
    $ins = mysqli_query($con, "Here goes insert statement for each");
}


编辑


$ISBN = $cart_itm["ISBN"];
$con = mysqli_connect("localhost","root","","yourbasename");
$result = mysqli_query($con, "SELECT Title,BookDesc, Price FROM books    
WHERE ISBN='$ISBN'");
while($row=mysqli_fetch_array($result)
{
    $insert = mysqli_query($con, "INSERT.....");
}

在这种情况下，您可以使用Ajax异步请求添加项目，而无需刷新页面。我将如何做到这一点？我从来没有真正使用过AjaxWait（我会在这里更新）…我假设我把代码放在if（isset（$_POST['submit_btn']）{line？得到一个错误，说是意外的{在第79行。while（$row=mysqli_fetch_array（$result））->我忘了一个“。用两个“）”（！）警告：reset（）预期参数1为数组，在C:\wamp\www\view\u cart.php第77forget reset（）行中给出null，只需再次进行选择查询并插入项，解决方案是循环遍历数组项，而不是只插入一个。因此，您可以拥有此解决方案的自己实现，因为您现在知道了无法插入这两本书的原因。
