Laravel 4: Adding where clause to a join condition

Question

It says in the laravel docs that it is possible to add where clause on a join, but whenever I try in my code using the where clause, I get the error: Call to undefined method Illuminate\Database\Query\JoinClause::where(). Anyone knows how to add where clause in a join clause?

Laravel Website Example:

DB::table('users')
->join('contacts', function($join)
{
  $join->on('users.id', '=', 'contacts.user_id')
  ->where('contacts.user_id', '>', 5);
})
->get();

Code I'm trying to implement:

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);
})
->get();

Answer 1

Try This solution

 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();

Answer 2

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();

Updated
In Laravel 4.0 which I think you use, you can't use where inside your join closure, but since Laravel 4.1 and above you can have where conditions after your join condition. I couldn't find documentation for Laravel 4.1 but this is the #join documentation for L4.2 and above
