Convert SQL Query into Laravel query - php

Question

I am trying to check the given input is already existed between the c_start and c_end through query, but it is not working. Here is my controller.. for example if person 1 booked a room from 10 to 12 then person can't book the same room at same date from 11 to 12 or any time between the existing booked time.
/* namespace App\booking; */
namespace App\Http\Controllers;
use App\booking;
use Illuminate\Http\Request;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Support\Facades\Auth;
use DB;
use App\Quotation;
use DateTime;
class RoombookController extends Controller {
public function insert_check(Request $request) {
$roomname = $request->input('roomname');
$book = $request->input('bookdate');
$dbstime = explode(':', $request->input('starttime'));
$dbetime = explode(':', $request->input('endtime'));
$dbstime[0] = $dbstime[0] * 60;
$dbetime[0] = $dbetime[0] * 60;
$dbsum = array_sum($dbstime);
$dbesum = array_sum($dbetime);
$users = DB::table("bookings")
->select("id")
->where('bookdate', '=', $request->input('bookdate'))
->where('roomname', '=', $request->input('roomname'))
->where(function ($query){
$query->where('c_start', '<', $dbsum);
$query->orWhere('c_end', '>', $dbsum);
})
->orWhere(function($query){
$query->where('c_start', '<', $dbesum);
$query->orWhere('c_end', '>', $dbesum);
});
if ($users->count() == 0) {
$booking = new booking;
$booking->bookdate = $request->input('bookdate');
$booking->roomname = $request->input('roomname');
$booking->starttime = $startTime = $request->input('starttime');
$booking->endtime = $finishTime = $request->input('endtime');
$booking->purpose = $request->input('Purpose');
$booking->booked_by = Auth::user()->id;
$smstime = explode(':', $startTime);
$emstime = explode(':', $finishTime);
$smstime[0] = $smstime[0] * 60;
$emstime[0] = $emstime[0] * 60;
$startsum = array_sum($smstime);
$endsum = array_sum($emstime);
$booking_time = $startTime . ' to ' . $finishTime;
$booking->c_start = $startsum;
$booking->c_end = $endsum;
$booking->booking_time = $booking_time;
$time = ($etime - $stime) / 60;
$booking->total_duration = $time;
$booking->save();
return view("bookmessage");
} else {
return view("duplicateValue");
}
}
}

Answer 1

Change query to:
$users = DB::table("bookings")
->select("id")
->where('bookdate', '=', $request->get('bookdate'))
->where('roomname', '=', $request->get('roomname'))
->where(function ($query) use ($dbsum, $dbesum){
$query->where(function ($query) use ($dbsum){
$query->where('c_start','<',$dbsum);
$query->Where('c_end','>',$dbsum);
})
->orWhere(function($query) use($dbesum){
$query->where('c_start','<',$dbesum);
$query->orWhere('c_end','>',$dbesum);
});
});

Try this code and let me know if it works:
$whereCondition = array('bookdate'=>$request->input('bookdate'),'roomname'=>$request->input('roomname'));
$users = DB::table("bookings")
->select("id")
->where($whereCondition)
->where(function ($query use $dbsum){
$query->where('c_start','<',$dbsum);
$query->orWhere('c_end','>',$dbsum);
})
->orWhere(function($query use $dbesum){
$query->where('c_start','<',$dbesum);
$query->orWhere('c_end','>',$dbesum);
})
->get();

You can run your sql query directly in laravel query builder .You can try this:
$sql = "SELECT * FROM `bookings` WHERE `bookdate`='2016-12-27' AND `roomname`='3' AND (($dbsum>`c_start` AND $dbsum<`c_end`) OR ($dbesum>`c_start` AND $dbesum<`c_end`))";
$result = DB::select(DB::raw($sql))
$result variable contains your output. You must be use your DB class
use DB;

Answer 4

this is the query from which i got my correct result
$whereCondition = array('bookdate'=>$request->input('bookdate'),'roomname'=>$request->input('roomname'));
$users = DB::table("bookings")
->select("id")
->where('bookdate', '=', $request->get('bookdate'))
->where('roomname', '=', $request->get('roomname'))
->whereRaw(DB::raw("((c_start<$dbsum and c_end>$dbsum) or (c_start<$dbesum and c_end>$dbesum ))"))
->get();
