Getting array of objects in laravel blade

Question

Am developing a website like Olx. I want to append the main categories and sub categories in menu bar. Am getting the return object like this for each element:

My controller code is:

$all_categories = [];
        $main_categories_name = Category::where('parent_id', 0)->pluck('name')->toArray();
        $main_categories_id = Category::where('parent_id', 0)->pluck('id')->toArray();        
        foreach($main_categories_id as $id){
          $name = Category::where('id', $id)->pluck('name');
          $sub_categories = Category::where('parent_id', $id)->pluck('name')->toArray();
          $all_categories[] = array('name' => $name, 'sub_categories' => $sub_categories);
        } 
        return $all_categories;

How do I get these elements in blade?

@foreach($all_categories as $category) 
                @foreach($category['name'] as $category) 
                  <li id="{{$category}}" name="{{$category}}" class="dropdown-submenu main_category"> <a class="maincategory" tabindex="-1" href="#"><span class="categoryname">{{$category}}</span></a>
                    <ul class="dropdown-menu">
                      <li class="subcategory" id="subcat"> sub_category
                      </li>
                    </ul>
                  </li>
                @endforeach
            @endforeach

I used like this. Now I want sub_categories in the name where I mentioned sub_category.

Am getting like this:

After using this code:

<ul class="dropdown-menu multi-level">
            @foreach($all_categories as $category)                 
              <li id="{{$category['name']}}" name="{{$category['name']}}" class="dropdown-submenu main_category"> <a class="maincategory" tabindex="-1" href="#"><span class="categoryname">{{$category['name']}}</span></a>
                <ul class="dropdown-menu">
                @foreach($category['sub_categories'] as $category) 
                  <li class="subcategory" id="subcat"><a href="#">{{$category}}</a></li>
                @endforeach
                </ul>
              </li>
            @endforeach
            </ul>

What to do for this? Am getting empty array like this?

Call the blade file with compact of that variable. In the blade use foreach to format accordingly — Thamilhan

return view('pages/home_page_product',compact('main','products', 'profile', 'all_categories','count','procat','probrand')); — Kayal

In the blade, use foreach($all_categories as $category) and process — Thamilhan

Return the view blade along with compact of that variable:

return view('yourblade',compact('all_categories'));

Then in the blade file, use foreach to parse the sub-categories:

foreach($all_categories as $category)

With formatting:

@foreach($all_categories as $category) 
    {{ $category['name'] }} // Prints men,... - format with your 
    @foreach($category['sub_categories'] as $subcategory) {
        {{ $subcategory }}  // Prints all your sub-categories under men,...
    @endforeach
@endforeach

Its the pluck that returns the array, use index to fetch [0] or pop() whichever you prefer

Can you check my emptyness problem

Check if the array is not empty before processing your inner foreach
