Hi, how to save many to many data?

I have post table [id, ‘title’], category[‘id’, ‘title’] and junction table post_category[post_id, category_id]

How to save these data:


{

	"title": "My new post",

	"categories": "1,2,3,4"

}

OR


{

	"title": "My new post",

	"categories": [1, 2, 3]

}

Did you look at link()?


$user = new User;

$user->name = 'Foo';

$user->save();


$market = new Market;

$market->name = 'Bar';

$market->save();


$user->link('markets', $market);
