如何修复"Uncaught PDOException: ...Conversion failed when converting date and/or time from character str

Question

我正在使用完整日历开发一个活动日历。在日历上删除了一个事件后，我出现了上述错误。日期格式似乎需要转换，我不确定该如何转换。在我之前的一个问题中，有人建议我使用yyyy-mm-dd-hh:mm这样的方法会更好，应该使用momentJs。

由于我是js的新手，我不确定我的代码应该如何更改以及更改什么。

这是代码：

document.addEventListener('DOMContentLoaded', function() {
var Calendar = FullCalendar.Calendar;
var Draggable = FullCalendarInteraction.Draggable;
var containerEl = document.getElementById('external-events');
var calendarEl = document.getElementById('calendar');
var checkbox = document.getElementById('drop-remove');

new Draggable(containerEl, {
itemSelector: '.fc-event',
eventData: function(eventEl) {
return {
title: eventEl.innerText
};
}
});
var calendar = new Calendar(calendarEl, {
plugins: ['interaction', 'dayGrid', 'timeGrid'],
header: {
left: 'prev,next today',
center: 'title',
right: 'dayGridMonth,timeGridWeek,timeGridDay'
},
editable: true,
droppable: true,
eventReceive: function(info) {
//get the bits of data we want to send into a simple object
var eventData = {
title: info.event.title,
start: info.event.start,
end: info.event.end
};
console.log(eventData);
//send the data via an AJAX POST request, and log any response which comes from the server
fetch('add_event.php', {
method: 'POST',
headers: {
'Accept': 'application/json'
},
body: encodeFormData(eventData)
})
.then(response => console.log(response))
.catch(error => console.log(error));
}
});
calendar.render();
});
const encodeFormData = (data) => {
var form_data = new FormData();
for (var key in data) {
form_data.append(key, data[key]);
}
return form_data;
}

<label for='drop-remove'>remove after drop</label>

<div id='calendar-container'>

add_event.php

require 'connection.php';
$title = $_POST['title'];
$start = $_POST['start'];
$end = $_POST['end'];
$conn = DB::databaseConnection();
$conn->beginTransaction();
$sqlInsert = "INSERT INTO Events ( title, start, [end]) VALUES ( :title, :start, :end)";
$stmt = $conn->prepare($sqlInsert);
$stmt->bindParam(':title', $title);
$stmt->bindParam(':start', $start);
$stmt->bindParam(':end', $end);
if ($stmt->execute()) {
$conn->commit();
return true;
} else {
$conn->rollback();
return false;
}
?>

事件详细信息需要保存在ms-sql数据库中。其函数在add_event.php文件中。请让我知道，如果你也想看到代码，也会发布。

如果您正在使用momentJS，并且假设您已经在页面中包含了momentJS文件，那么：

start:moment(info.event.start).format("YYYY-MM-DD HH:mm"),
end:moment(info.event.start).format("YYYY-MM-DD HH:mm" )

应该做到这一点。看见https://momentjs.com/docs/#/displaying/format/详细信息。
