Framework: Add parameters to closure of whereHas

[let-aurn]

Doc says

// Retrieve all posts with at least one comment containing words like foo%
$posts = Post::whereHas('comments', function ($query) {
    $query->where('content', 'like', 'foo%');
})->get();

What if we want to pass args to the closure? Like this

// Retrieve all posts with at least one comment containing words like given
$posts = Post::whereHas('comments', function ($query, $search) {
    $query->where('content', 'like', '%$search%');
})->get();

In Eloquent\Builder.php#has() we have

    if ($callback) {
        call_user_func($callback, $query);
    }

which use $query as the one and only parameter.

[acasar]

$posts = Post::whereHas('comments', function ($query) use ($search) {
    $query->where('content', 'like', '%$search%');
})->get();

[lagbox]

Blah::whereHas('relation', function ($q) use ($anyvaryouwant) {
     $q->where('something', $anyvaryouwant);
});

@acasar I guess I am a lagging box :)
