我试图创建一个报告页面，显示从特定日期到特定日期的报告。这是我当前的代码:
$now = date('Y-m-d');
$reservations = Reservation::where('reservation_from', $now)->get();
这在普通SQL中所做的是从表中选择*，其中reservation_from = $now。
我在这里有这个问题，但我不知道如何将其转换为雄辩的问题。
SELECT * FROM table WHERE reservation_from BETWEEN '$from' AND '$to
如何将上面的代码转换为雄辩的查询?
当前回答
让我用准确的时间戳添加正确的语法
之前
$from = $request->from;
$to = $request->to;
Reservation::whereBetween('reservation_from', [$from, $to])->get();
后
$from = date('Y-m-d', strtotime($request->from));
$to = date('Y-m-d', strtotime($request->to));
Reservation::whereBetween('reservation_from', [$from, $to])->get();
注意:如果您以字符串形式存储日期，那么请确保在from和to中传递准确的格式。它将与DB匹配。
其他回答
如果你的字段是datetime而不是date(尽管它适用于这两种情况):
$fromDate = "2016-10-01";
$toDate = "2016-10-31";
$reservations = Reservation::whereRaw(
"(reservation_from >= ? AND reservation_from <= ?)",
[
$fromDate ." 00:00:00",
$toDate ." 23:59:59"
]
)->get();
以下方法应该有效:
$now = date('Y-m-d');
$reservations = Reservation::where('reservation_from', '>=', $now)
->where('reservation_from', '<=', $to)
->get();

@masoud，在Laravel，你必须从表单请求字段值。所以,
Reservation::whereBetween('reservation_from',[$request->from,$request->to])->get();
而在livewire中，略有变化
Reservation::whereBetween('reservation_from',[$this->from,$this->to])->get();
whereBetween方法验证列的值是否在between之间 两个值。
$from = date('2018-01-01');
$to = date('2018-05-02');
Reservation::whereBetween('reservation_from', [$from, $to])->get();
在某些情况下，需要动态添加日期范围。根据@Anovative的评论，你可以这样做:
Reservation::all()->filter(function($item) {
if (Carbon::now()->between($item->from, $item->to)) {
return $item;
}
});
如果你想添加更多的条件，那么你可以使用orWhereBetween。如果你想要排除一个日期间隔，那么你可以使用whereNotBetween。
Reservation::whereBetween('reservation_from', [$from1, $to1])
->orWhereBetween('reservation_to', [$from2, $to2])
->whereNotBetween('reservation_to', [$from3, $to3])
->get();
其他有用的where子句:whereNotIn, whereenull, whereNotNull, whereDate, whereMonth, whereDay, whereYear, whereTime, whereColumn, whereExists, whereRaw。
