删除确认 HREF Sweet Alert

Question

我似乎无法用该论坛的相同逻辑解决这个问题。我正在开发一个预订模块，它具有确认或取消预订的功能。这是我的PHP代码，它告诉您预订是否已确认、取消或尚未确认。Status==0(Not Confirmed yet) - 默认一个，Status==1(Confirmed) 和Status==2(Cancelled)<?phpsession_start();error_reporting(0);include('includes/config.php');if(strlen($_SESSION['alogin'])==0)    {   header('location:index.php');}else{if(isset($_REQUEST['eid']))    {$eid=intval($_GET['eid']);$status="2";$sql = "UPDATE tblbooking SET Status=:status WHERE  id=:eid";$query = $dbh->prepare($sql);$query -> bindParam(':status',$status, PDO::PARAM_STR);$query-> bindParam(':eid',$eid, PDO::PARAM_STR);$query -> execute();$msg="Booking Successfully Cancelled";}if(isset($_REQUEST['aeid']))    {$aeid=intval($_GET['aeid']);$status=1;$sql = "UPDATE tblbooking SET Status=:status WHERE  id=:aeid";$query = $dbh->prepare($sql);$query -> bindParam(':status',$status, PDO::PARAM_STR);$query-> bindParam(':aeid',$aeid, PDO::PARAM_STR);$query -> execute();$msg="Booking Successfully Confirmed";}<?php $sql = "SELECT tblbooking.Status";$query = $dbh -> prepare($sql);$query->execute();$results=$query->fetchAll(PDO::FETCH_OBJ);$cnt=1;if($query->rowCount() > 0){  foreach($results as $result){?>if($result->Status==0){echo htmlentities('Not Confirmed yet');} else if ($result->Status==1) {echo htmlentities('Confirmed');}else{echo htmlentities('Cancelled');}这是原始代码，将通过基本Javascript警报确认/取消预订<td><button class="btn btn-sm btn-primary"><a href="manage-bookings.php?aeid=<?php echo htmlentities($result->id);?>" onclick="return confirm('Do you really want to Confirm this booking')"> <i style="color: #fff;" class='fa fa-check'></i></a></button><button class="btn btn-sm btn-danger"><a href="manage-bookings.php?eid=<?php echo htmlentities($result->id);?>" onclick="return confirm('Do you really want to Cancel this booking')"> <i style="color: #fff;" class='fa fa-close'></i></a></button></td>

在我看来，您实际上从未将任何数据发送回服务器。

内置的 javascript 确认对话框会中断您的超链接，然后在您点击 OK 后允许它恢复。

Sweetalerts 似乎不这样做。因此，您永远不会重定向到您需要访问的页面。您可以使用 javascript 重定向到正确的 URL，或者您可以为您尝试执行的操作编写服务器端 API，并在“willDelete”案例中从 AJAX 调用该 API。

这是前一个选项：

<script>

    function confirmation(ev) {

        ev.preventDefault();

        var urlToRedirect = ev.currentTarget.getAttribute('href'); //use currentTarget because the click may be on the nested i tag and not a tag causing the href to be empty

        console.log(urlToRedirect); // verify if this is the right URL

        swal({

            title: "Are you sure you want to tag this booking as confirmed",

            text: "You will not be able to revert this!",

            icon: "warning",

            buttons: true,

            dangerMode: true,

        })

        .then((willDelete) => {

            if (willDelete) {

                // redirect with javascript here as per your logic after showing the alert using the urlToRedirect value

                window.location.href = urlToRedirect;

            } else {

                swal("You booking hasn't been confirmed.");

            }

        });

    }

</script>
