【问题描述】：
这是我的 derp 时刻，卡住了...我有一个 ajax 调用去控制器操作，我有一个比较两个日期戳的查询，我收到以下错误：
前端js循环和ajax
while(count <= toursToday){
tourtimeFormatted = moment.utc(tourtime);
var html = '<button data-id="<?= $tour->id ?>" data-timeslot="'+tourtimeFormatted+'" class="btn btn-default timeSlot">'+formatAMPM(tourtime)+'</button>';
$('#tourDetails').append(html);
tourtime.setMinutes(tourtime.getMinutes() + 30);
console.log(tourtime);
count++;
}
$('body').on('click', 'button.timeSlot', function() {
alert('clicked');
var time = $(this).data('timeslot');
var tour_id = $(this).data('id');
//ajax get avaliable seats
$.ajax({
method: "POST",
url: "/getseats.json",
data: { tour_id: tour_id, date_time: time }
})
.success(function( data ) {
});
});
错误和后端显示更多关于正在发生的事情。我想我的日期比较错误，但我不确定在哪里......

【问题讨论】：
-
错误是否说明是哪一行导致了转换错误？但是当您有
$foo = array(); echo $foo;或$bar = 'this will end well' . $foo之类的东西时会发生确切的错误 - 在字符串上下文中使用数组。 -
我认为是查询，传入的是2016-07-17T15:00:00-05:00
-
以下是响应中附加的错误消息： 注意 (8)：数组到字符串的转换 [CORE/src/ORM/Table.php，第 1782 行] 警告 (2)：strtolower() 需要参数1为字符串，给定数组[CORE/src/ORM/BehaviorRegistry.php，第215行]注意（8）：数组到字符串转换[CORE/src/ORM/Table.php，第1792行]
-
无论何时收到错误，请始终发布 complete 错误消息，包括 full 堆栈跟踪（最好从日志中正确复制可读时尚）在您的问题中，即使问题对于熟悉 CakePHP 的人来说可能很明显！另外，请务必提及您的 准确 CakePHP 版本 (x.x.x)！
-
我知道，但这不是 确切 版本，确切的版本号由三个数字组成，例如
3.2.1（检查vendor/cakephp/cakephp/VERSION.txt）。在不知道确切版本的情况下，很难弄清楚错误消息指的是什么代码。理想情况下，您也可以将 that 放在您的问题中。
