Let’s take an example suppose we are making a filter which sorts the products by low-to-heigh , heigh-to-low etc…

Assume if we want to add more filter for eg- filter by category so we can add category like this: switch($this->sortBy){ case 'low-to-heigh': Product::where('category_id',$categoryId)->orderBy('sale_price', 'asc')->get(); case 'heigh-to-low': Product::where('category_id',$categoryId)->orderBy('sale_price', 'desc')->get(); case 'featured': Product::where('category_id',$categoryId)->where('featured',-1)->get(); default: Product::all(); }

First of all we will define a scope called SortBy: and we will add an additional parameter called $sortBy which will be dynamic and we will copy the filter code into scope public function scopeSortBy($query,$sortBy) { switch($sortBy){ case 'low-to-heigh': $query->orderBy('sale_price', 'asc')->get(); case 'heigh-to-low': $query->orderBy('sale_price', 'desc')->get(); case 'featured': $query->where('featured',-1)->get(); default: Product::all(); }} now lets define another dynamic scope called scopeCategoryFilter and we will add the category query inside the scope public function scopeCategoryFilter($query,$category) { $query->where('category_id',$category); } now lets merge this scope into 1 query
