Laravel Eloquent query fails on Eloquent but success in PhpMyAdmin - laravel

Question

Laravel 4.2
Here are my tables
sk__queue :
+----------+----------+---------------------+--------+
| idQueue | idCap | date | status |
+----------+----------+---------------------+--------+
| 1350 | 7 | 2015-10-20 11:20:00 | 9 |
| 1427 | 7 | 2015-10-29 14:20:00 | 4 |
| 1428 | 7 | 2015-10-29 14:19:00 | 4 |
+----------+----------+---------------------+--------+
sk__cloc
+----------+----------+-----------+-----+---------------------+--------------------------+
| idCloc | idCap | cDuration | cNb | begin | end |
+----------+----------+-----------+-----+---------------------+--------------------------+
| 1 | 7 | 10 | 3 | 2015-01-01 08:00:00 | 2015-12-31 22:30:00 |
+----------+----------+-----------+-- --+---------------------+--------------------------+
A spot is available if the sk__queue.status is < 4 or > 7
I want to know how many spots are available between the last 10 minutes and 10 minutes in the future.
My Eloquent query is like that :
//$now = date('Y-m-d H:i:s');
$now = "2015-10-29 14:12:08";
$dispo = DB::table('sk__cloc')->leftJoin('sk__queue', function($join) use ($now) {
$join->on('sk__queue.idCap', '=', 'sk__cloc.idCap');
$join->where('sk__queue.date', '>=', "('$now' - INTERVAL cDuration MINUTE)");
$join->where('sk__queue.date', '<=', "('$now' + INTERVAL cDuration MINUTE)");
$join->where('sk__queue.date', '>=', 'sk__cloc.begin');
$join->where('sk__queue.date', '<=', 'sk__cloc.end');
$join->where('sk__queue.status', '>=', 4);
$join->where('sk__queue.status', '<=', 7);
})
->where('sk__cloc.idCap', '=', 7)
->groupBy('cNb')
->select(DB::raw('cNb*2, count(sk__queue.idCap) AS count'))
->first();
Result : "cNb*2":6, "count":0
Now I'm doing DB::getQueryLog() and this is the laravel request :
select cNb*2, count(sk__queue.idCap) AS count, sk__queue.date
from `sk__cloc` left join `sk__queue`
on `sk__queue`.`idCap` = `sk__cloc`.`idCap`
and `sk__queue`.`date` >= ('2015-10-29 14:12:08' - INTERVAL cDuration MINUTE)
and `sk__queue`.`date` <= ('2015-10-29 14:12:08' + INTERVAL cDuration MINUTE)
and `sk__queue`.`date` <= sk__cloc.end
and `sk__queue`.`status` >= 4
and `sk__queue`.`status` <= 7
where `sk__cloc`.`idCap` = 7
group by cNb
In PhpMyAdmin, the result is : "cNb*2":6, "count":2
Then I commented those lines :
//$now = date('Y-m-d H:i:s');
$now = "2015-10-29 14:12:08";
$dispo = DB::table('sk__cloc')->leftJoin('sk__queue', function($join) use ($now) {
$join->on('sk__queue.idCap', '=', 'sk__cloc.idCap');
$join->where('sk__queue.date', '>=', "('$now' - INTERVAL cDuration MINUTE)");
//$join->where('sk__queue.date', '<=', "('$now' + INTERVAL cDuration MINUTE)");
//$join->where('sk__queue.date', '>=', 'sk__cloc.begin');
$join->where('sk__queue.date', '<=', 'sk__cloc.end');
$join->where('sk__queue.status', '>=', 4);
$join->where('sk__queue.status', '<=', 7);
})
->where('sk__cloc.idCap', '=', 7)
->groupBy('cNb')
->select(DB::raw('cNb*2, count(sk__queue.idCap) AS count'))
->first();
Result : "cNb*2":6, "count":2
My only question is : What is happining right here ?! I'm so confused.
Thanks for your help.

You should keep joining "on":
$join->on('sk__queue.idCap', '=', 'sk__cloc.idCap');
$join->on('sk__queue.date', '>=', "('$now' - INTERVAL cDuration MINUTE)");
$join->on('sk__queue.date', '<=', "('$now' + INTERVAL cDuration MINUTE)");
$join->on('sk__queue.date', '>=', 'sk__cloc.begin');
$join->on('sk__queue.date', '<=', 'sk__cloc.end');
$join->on('sk__queue.status', '>=', 4);
$join->on('sk__queue.status', '<=', 7);
