Its really difficult to iterate and show Parent child Categories tree or listing in Laravel, sometimes it affect websites performance,
To solve this problem we need to use a recursive blade.
Just follow this steps to make it happen
- First of all we need to get all the categories and childs.
To get all categories with childs, create a childs
function inside the Category model
public function childs()
{
return $this->hasMany(Category::class, 'parent_id', 'id');
}
this function will return all categories with its childs
then fetch categories in your controller like below code
$categories = Category::whereNull('parent_id')->with('childs')->get();
2.inside your blade
@foreach($categories as $category)
<li>
{{{ $category->category_name }}}
@if(count($category->childs))
@include('category-partial ',['childs' => $category->childs])
@endif
</li>
@endforeach
3.Create category-partial.blade which we are using to loop each of the category so that we can show the category without a limit
<ul>
@foreach($childs as $child)
<li>
<a href="{{{ url('search/?category='.$child->category_name.'-'.$child->id.'&q=') }}}">{{{ $child->category_name }}}</a>
@if(count($child->childs))
@include('admin.managechild',['childs' => $child->childs])
@endif
</li>
@endforeach
</ul>

how do you limit the numbers of categories(total of both parent and child) to show on the page?
you paginate. where you do
$categories = Category::whereNull('parent_id')->with('childs')->get();you can do$categories = Category::whereNull('parent_id')->with('childs')->paginate(x);where x is the number of items you want to show on page.that will do pagination based on the count of the
parent_idcategory.I wanted to display the categories with a hierarchy. Ended up with this:
