I have two tables. One is user and the other is category, I have written this Eloquent ORM query to retrieves data from category
$category = Category::where(['status'=>'active'])->orderBy('id','asc')->get();
In category table here has a field called user_id. I want to join the user table and want to retrieve the user name where category table 'user_id' == user table 'id'.

Then how to get relationship this five table?
you have to create a many-to-many relationship between tables and use pivot table to show the relationship between table rows using foreignId
I have 3 tables name like "product" , "user", "product_type" so in my case user and product_type having many to many relationship and user and product having one to many relationship and product and product_type having one to one relationship.
I create one pivot table for user and product_type. inside that pivot table, I added one more column for description. so in product listing page I need to display description from that pivot table.
My code look like this:
Product::with('user)->with('product_type')->get();
To get extra fields from pivot table you need to use withPivot in function of your model Like this:
public function product_type() {
return $this->belongsToMany('App\Product','product_type','product_id','user_id')->withPivot('column1', 'column2');
}
you may also refer laravel docs for it:

I've 2 Models, let's say: Cart and Product.
Cart has many Product. Product belongs to Cart
3 tables cart, product, cart_product (id, cart_id, product_id)
I insert another field to cart_product, ex: (id, cart_id, product_id, quantity).
When I attach a Product to a Cart how can I query the relation to insert a quantity?
self answer:
$cart->products()->attach($p, array('blablabla', 'blablabla'));
