[英]Delete confirmation HREF Sweet Alert
但是我似乎無法使用該論壇中的相同邏輯來解決此問題。
我正在開發一個預訂模塊,它具有確認或取消預訂的功能。 這是我的PHP
代碼,告訴您預訂是否已確認,取消或尚未確認。 Status==0
(尚未確認)-默認值, Status==1
(已確認)和Status==2
(已取消)
<?php
session_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 ($result->Status==1) {
echo htmlentities('Confirmed');
}
else{
echo htmlentities('Cancelled');
}
這是原始代碼,將使用基本的Javascript
警報來確認/取消預訂
<td><button class="btn btn-sm btn-primary"><a href="manage-bookings.php?aeid=<?php echo htmlentities($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($result->id);?>" onclick="return confirm('Do you really want to Cancel this booking')"> <i style="color: #fff;" class='fa fa-close'></i></a></button></td>
但是我想使用sweetalert,所以我對此進行了修改(首先使用錨進行測試)
<a href="manage-bookings.php?aeid=<?php echo htmlentities($result->id);?>" onclick="confirmation(event)">Confirm</a>
這是script
<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) => {
// redirect with javascript here as per your logic after showing the alert using the urlToRedirect value
if (willDelete) {
swal("Your booking as been confirmed!", {
icon: "success",
});
} else {
swal("You booking hasn't been confirmed.");
}
});
}
</script>
問題是,警報起作用。 它會創建一個彈出確認,但它不會完全確認/取消預訂,盡管
href
鏈接與原始鏈接說的是相同的內容,但原始鏈接會重新加載頁面並進行標記。
在我看來,您實際上從未真正將任何數據發送回服務器。
內置的javascript確認對話框會中斷您的超鏈接,然后在您單擊“確定”后恢復它。
看起來Sweetalerts不會這樣做。 因此,您永遠不會重定向到需要訪問的頁面。 您可以使用javascript重定向到正確的URL,或者可以為要執行的操作編寫服務器端API,然后在“ willDelete”案例中從AJAX調用該API。
這是前一個選項:
<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>
