Laravel 7: Adding where clause to a join condition

if you want add more condition on a join add more $join->on or $join->orOn.


if you want to add a condition to your first select, add it outside join function.

DB::table('users')
->join('contacts', function($join)
{
    $date = date('Y-m-d');
    $join->on('users.id', '=', 'contacts.user_id');
})
->where('contacts.effective_date', '>=', $date);
->get();

 DB::table('users')
            ->join('contacts', function($join)
            {
                $current_date = date('Y-m-d');
                $join->on('users.id', '=', 'contacts.user_id')
                     ->where('contacts.effective_date', '>', $current_date)
             ->where('contacts.effective_date', '=', $current_date);

            })
            ->get();

$current_date = date('Y-m-d');
DB::table('users')
->join('contacts', function($join) use ($current_date)
{
  $join->on('users.id', '=', 'contacts.user_id')
      ->where('contacts.effective_date', '>=', $current_date);
})
->get();
