Laravel: many to many relationship - luannguyenQV/laravel-framework-demo-full-blog GitHub Wiki
As you can see in Laravel document: https://laravel.com/docs/5.3/eloquent-relationships#many-to-many, we have enough document for Many to Many relationship. And, in my project, I apply for: Product and Category[Nested Category], Post and Tag. But, the most difficult thing spend my time is how to edit the Products, with many checkbox for Category. I try to find how to apply HTMLCollective for this case, but no result.
Here is my Solution.
Product:
class Product extends Model
{
`public function categories() {`
`return $this->belongsToMany('App\Category', 'products_categories'); //product_id category_id`
`}`
}
Category:
class Category extends Node {
/**
* Table name.
*
* @var string
*/
protected $table = 'categories';
public function products() {
return $this->belongsToMany('App\Product', 'products_categories');
}
}
_** That is nested category using Baum Nested Category _
public function edit($id) {
$product = Product::find($id);
$curCategory = $product->categories;
return view('backend.products.edit')->with([
'product' => $product, 'categories' => $this->categories, 'curCategory' => $curCategory,
]);
}
@foreach($categories as $node)
