A JOIN With Additional Conditions Using Query Builder or Eloquent

Question

I\'m trying to add a condition using a JOIN query with Laravel Query Builder.

Answer 1

You can replicate those brackets in the left join:

LEFT JOIN bookings  
               ON rooms.id = bookings.room_type_id
              AND (  bookings.arrival between ? and ?
                  OR bookings.departure between ? and ? )

is

->leftJoin('bookings', function($join){
    $join->on('rooms.id', '=', 'bookings.room_type_id');
    $join->on(DB::raw('(  bookings.arrival between ? and ? OR bookings.departure between ? and ? )'), DB::raw(''), DB::raw(''));
})

You'll then have to set the bindings later using "setBindings" as described in this SO post: How to bind parameters to a raw DB query in Laravel that's used on a model?

It's not pretty but it works.
