    <!-- .megamenu / end -->
    </div>
    </li>@endforeach</ul>

我怎么从这里走?

推荐答案

您需要更新类别模型

category.php

<?php
namespace App;
use Illuminate\Database\Eloquent\Model;

class category extends Model
{
    public $table = "category";
    public function products()
    {
        return $this->hasMany('App\product', 'ID', 'p_id');
    }
}

类别视图

<div class="nav-panel__nav-links nav-links">
    <ul class="nav-links__list">
        @foreach(App\category::with('products')->where('p_id',0)->first()->products as $firstmenu)
            <li class="nav-links__item  nav-links__item--has-submenu ">
                <a id="cate" class="nav-links__item-link" href="{{$firstmenu->cate_name}}">
                    <input type="hidden" name="cate"  value="{{$firstmenu->id}}">
                    <div  class="nav-links__item-body">
                        {{$firstmenu->cate_name}}
                        <svg class="nav-links__item-arrow" width="9px" height="6px">
                            <use xlink:href="public/assets/images/sprite.svg#arrow-rounded-down-9x6"></use>
                        </svg>
                    </div>
                </a>
            <li>
    </ul>
</div>
