Question

$bed_count = $request->get('bed_count');
$data = Accommodation::with(['city','accommodationRoomsLimited.roomPricingHistorySearch' =>function($query) use($from_date,$to_date){
$query->whereDate('from_date', '<=', $from_date);
$query->whereDate('to_date', '>=', $to_date);
},'accommodationRoomsLimited' => function($q) use($bed_count){
//here is I want my query to be executed if the user sends bed_count if not the code should skip this part
$q->orWhere('bed_count',$bed_count);
}])

Answer 1

Not clear what are you trying to achieve.
If you want to eager load accommodationRoomsLimited all the time,
But when user has provided bed count, you need to filter those accommodationRoomsLimited with this bed count.
If that's so
$bed_count = $request->get('bed_count');
$data = Accommodation::with([
'city',
'accommodationRoomsLimited.roomPricingHistorySearch' => function($query) use($from_date,$to_date) {
$query->whereDate('from_date', '<=', $from_date);
$query->whereDate('to_date', '>=', $to_date);
},
'accommodationRoomsLimited' => function($q) use($bed_count) {
if ($bed_count) {
$q->where('bed_count',$bed_count);
}
}
]);
If you only want to eager load accommodationRoomsLimited only when user has provided bed count.
Then
$bed_count = $request->get('bed_count');
$data = Accommodation::with([
'city',
'accommodationRoomsLimited.roomPricingHistorySearch' => function($query) use($from_date,$to_date) {
$query->whereDate('from_date', '<=', $from_date);
$query->whereDate('to_date', '>=', $to_date);
},
])
->when($bed_count, function ($query, $bed_count) {
$query->with([
'accommodationRoomsLimited' => function($q) use($bed_count) {
$q->where('bed_count',$bed_count);
}
]);
});
