我想用php删除数据库记录。在提交表格摘要之前，我希望通过“是”按钮通知“甜蜜提醒”（2）。
当“是”时，我想提交表单并激活我的php代码。
问题是它不起作用。单击“是”后，我的页面正在刷新，并且我的php代码无法启动。
<form action="" method="POST">
<div class="right gap-items-2">
<button class="btn btn-error" name="archive" type="submit" onclick="archiveFunction()">archive</button>
</div>
</form>
<script>
function archiveFunction() {
event.preventDefault(); // prevent form submit
var form = event.target.form; // storing the form
Swal.fire({
title: 'Are you sure?',
text: "You won't be able to revert this!",
type: 'warning',
showCancelButton: true,
confirmButtonColor: '#3085d6',
cancelButtonColor: '#d33',
confirmButtonText: 'Yes, delete it!'
}).then((result) => {
if (result.value) {
form.submit();
}
})
}
</script>
if (isset($_POST['archive'])){
$message = "test";
echo "<script type='text/javascript'>alert('$message');</script>";
}

使用如下ID修改表单按钮：
<form action="" method="POST">
<div class="right gap-items-2">
<button class="btn btn-error" name="archive" type="submit" id="submitForm" >archive</button>
</div>
</form>
然后是这样的脚本：
<script>
$('#submitForm').on('click',function(e){
e.preventDefault();
var form = $(this).parents('form');
Swal.fire({
title: 'Are you sure?',
text: "You won't be able to revert this!",
type: 'warning',
showCancelButton: true,
confirmButtonColor: '#3085d6',
cancelButtonColor: '#d33',
confirmButtonText: 'Yes, delete it!'
}).then((result) => {
if (result.value) {
form.submit();
}
});
});
</script>

尝试一下，我在laravel中使用了它，
<td>
<form class="archiveItem"
action="{{route('archive.destroy',['id'=>$archive->id])}}"
method="Post">
{{method_field('DELETE')}}
{{csrf_field()}}
<input type="hidden" name="archive">
<a onclick="archiveRemove(this)" class="deleteRecord"
id="{{$archive->id}}"
style="cursor: pointer"><i class="fa fa-trash"
style="font-size: 20px;color: #000"></i>
</a>
</form>
和脚本中
function archiveRemove(any) {
var click = $(any);
var id = click.attr("id");
swal.fire({
title: 'Are you sure !',
text: "?????",
type: 'warning',
showCancelButton: true,
confirmButtonColor: '#3085d6',
cancelButtonColor: '#d33',
confirmButtonText: 'yes!',
cancelButtonText: 'no'
}).then(function (success) {
if (success) {
$('a[id="' + id + '"]').parents(".archiveItem").submit();
}
})
}
