my code is
My controller
:
$start_date = $request->has('startDate') ? $request->get('startDate') : Carbon::now()->subDays(30)->format('m/d/Y');
$end_date = $request->has('endDate') ? Carbon::parse($request->get('endDate'))->addDays(1)->format('m/d/Y') : Carbon::now()->addDays(1)->format('m/d/Y');
if i use created at it works
$participants = Participant::Where('created_at', '>=', $start_date)
->where('created_at', '<=', $end_date);
if is use start_time which is inside a array it returns empty
$participants = Participant::Where('data->meta->start_time', '>=', $start_date)
->where('data->meta->start_time', '<=', $end_date);
this isn't working
any suggestion where am i wrong ?

Answer 1

I have tested your code and I think you should change your date format and you should receive startDate and endDate in the same format form request as your column value has. Like, you have the start_time something like that "start_time": "2019-09-06" in your DB. So, use the same date format when you will compare it.
Test your code in this way.
$start_date = Carbon::parse('2019-09-06')->format('Y-m-d');
$end_date = Carbon::parse('2019-09-10')->format('Y-m-d');
You will get a response but if you use the below format then you will not receive any response.
$start_date = Carbon::parse('2019-09-06')->format('m/d/Y');
$end_date = Carbon::parse('2019-09-10')->format('m/d/Y');
Your query is fine. Just make sure that your json column name is data.
$participants = Participant::where('data->meta->start_time', '>=', $start_date)
->where('data->meta->start_time', '<=', $end_date)->get();

Use whereBetween method of elocuent:
$start_date = $request->has('startDate') ? $request->get('startDate') : Carbon::now()->subDays(30)->format('m/d/Y');
$end_date = $request->has('endDate') ? Carbon::parse($request->get('endDate'))->addDays(1)->format('m/d/Y') : Carbon::now()->addDays(1)->format('m/d/Y');
$participants = Participant::whereBetween('start_time', [$start_date , $end_date])->get(); // or ->first() ur choice.
