比较 Laravel eloquent 中的日期时间

Question

我在数据库中有开始和结束日期时间列

start_date             end_date             contact
2021-01-25 17:30:00    2021-01-25 20:30:00   xxxxxxxxx
2021-01-27 17:30:00    2021-01-28 19:30:00   xxxxxxxxx

现在我正在尝试获取这两个日期时间之间存在的记录，它也应该与手机号码匹配。我正在使用下面的查询，但它没有过滤记录

   $date = date('Y-m-d H:i:s', strtotime($request->date));
   $contact_number=$request->contact_number;

$event=Event::where(function ($query)use($date,$contact_number){
    $query->where('start_date', '>=', $date)->where('end_date', '<=', $date);})->where('contact',$contact_number)->paginate(5);  

Answer 1

您必须反转 >= 和 <= 符号

$date = date('Y-m-d H:i:s', strtotime($request->date));
$contact_number = $request->contact_number;

$event = Event::where(function ($query) use ($date, $contact_number){
        $query->where('start_date', '<=', $date)
              ->where('end_date', '>=', $date);
    })
    ->where('contact',$contact_number)
    ->paginate(5); 

Answer 2

Laravel 4+ offers you these methods: whereDay(), whereMonth(), whereYear()  and whereDate() .




Here are some ways to make the comparison :

->where('date', '<=', '2014-07-10 23:59:59')

->where('date', '<', '2014-07-11')

// '2014-07-11'
$dayAfter = (new DateTime('2014-07-10'))->modify('+1 day')->format('Y-m-d');

->where('date', '<', $dayAfter)

Answer 3

试试这个：

$date = Carbon\Carbon::parse($request->date)->format('Y-m-d H:i:s');
$contact_number=$request->contact_number;

$event=Event::where(function ($query)use($date,$contact_number){
    $query->where('start_date', '<=', $date)->where('end_date', '>=', $date);})->where('contact',$contact_number)->paginate(5);
