Laravel 4.2: How to convert raw query to Eloquent - php

Question

I have a raw query which works fine.
$qry ="select date(created_at) as Date,count(id) as Value from performances where date_format(created_at,'%d-%m-%Y') >= '$start_date' and date_format(created_at,'%d-%m-%Y') <= '$to_date' group by Date order by Date desc ";
$stats = DB::select( DB::raw($qry) );
return json_encode($stats);
I would like to convert it in to Eloquent
My controller function is
public function postPerformanceDetails()
{
$start_date = Input::get('start_date');
$to_date = Input::get('to_date');
$start_date = date('Y-m-d',strtotime($start_date));
$to_date = date('Y-m-d',strtotime($to_date));
$stats = Performance::where('created_at', '>=', $start_date)
->where('created_at','<=',$to_date)
->groupBy('perf_date')
->orderBy('perf_date', 'DESC')
->remember(60)
->get([
DB::raw('Date(created_at) as perf_date'),
DB::raw('COUNT(id) as perf_count')
])
->toJSON();
return $stats
}
The raw query works fine but eloquent does not work according to the date input.
I input data in this format 09-03-2015
in database the format is 2015-03-09
If we give 2015-03-09 as start_date and to_date it returns empty string.
Is there any problem with formats?
How can i solve this issue?

Answer 1

The easiest way would be to convert the date in PHP to the database format.
$start_date = date('Y-m-d', strtotime($start_date));
This should lead to your database format: 2015-03-09.

Answer 2

I got the answer as #sleepless suggested.
This is the code.
public function postPerformanceDetails()
{
$event = Input::get('events');
$start_date = Input::get('start_date');
$to_date = Input::get('to_date');
$start_date = date('Y-m-d H:i:s',strtotime($start_date.'00:00:00'));
$to_date = date('Y-m-d H:i:s',strtotime($to_date.'23:59:59'));
$stats = Performance::where('created_at', '>=', $start_date)
->where('created_at','<=',$to_date)
->groupBy('perf_date')
->orderBy('perf_date', 'DESC')
->remember(60)
->get([
DB::raw('Date(created_at) as perf_date'),
DB::raw('COUNT(id) as perf_count')
])
->toJSON();
return $stats;
}
