How do I get all children that fall under a parent in eloquent?

Question

In my database, I have a Categories table. Categories can have parent categories, making it a recursive relationship

I also have a products table. Each product falls

Answer 1

Say $category_id = Category->id and you want a collection of products as children of that category, I would try:

$products = App\Product::with(['SubSubCategory.SubCategory.Category'=>function($query) use ($category_id) {$query->where('id', $category_id);}])->get();

To be able to do so. You will need your 'one to many' inverse relationships to be as such:

//App\SubCategory

public function Category(){return $this->belongsTo('App\Category');}

//App\SubSubCategory

public function Sub_Category(){return $this->belongsTo('App\SubCategory');}

//App\Product

public function SubSubCategory(){return $this->belongsTo('App\SubSubCategory');}

Good luck.
