买家下的订单没有显示给卖家 Laravel

Question

我正在尝试让买家看到的订单被相应的卖家看到，但它没有显示任何内容。

我已经尝试了几个小时来解决这个问题，但我仍然卡住了。

这是我的模型Order.php

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Order extends Model
{
    //protected $table = 'orders';
    protected $fillable =  [
        'user_id', 'shipping_email', 'shipping_name', 'shipping_city',    'shipping_phone', 'billing_subtotal', 'billing_total',
    ];

    public function user()
    {
        return $this->belongsTo('App\User');
    }

    public function products()
    {
        return $this->belongsToMany('App\Products_model')->withPivot('quantity');
    }

    public function orders(){
        return $this->hasMany('App\OrderProduct', 'order_id');
    }
}

这是我的 OrderProduct.php

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class OrderProduct extends Model
{
    protected $table = 'order_product';
    protected $fillable = ['order_id', 'product_id', 'quantity'];

    public function products()
    { 
        return $this->belongsTo('App\Products_model');
    }
}

这是我的User.php

<?php

namespace App;

use Illuminate\Notifications\Notifiable;
use Illuminate\Contracts\Auth\MustVerifyEmail;
use Illuminate\Foundation\Auth\User as Authenticatable;

class User extends Authenticatable
{
    use Notifiable;

    /**
     * The attributes that are mass assignable.
     *
     * @var array
     */
    protected $fillable = [
        'name', 'email', 'password', 'Seller'
    ];

    /**
     * The attributes that should be hidden for arrays.
     *
     * @var array
     */
    protected $hidden = [
        'password', 'remember_token', 
    ];

    public function products()
    {
        return $this->hasMany(Products_model::class);
    }

    /**
     * The attributes that should be cast to native types.
     *
     * @var array
     */
    protected $casts = [
        'email_verified_at' => 'datetime',
    ];

    public function orders()
    {
        $this->hasManyThrough(Order::class, Products_model::class, 'user_id', 'product_id');
    }
}

最后是我在 ProductController

中的 viewOrder 函数

//Orders View Function
public function viewOrders(User $user)
{
    $products = Products_model::where('user_id', '=', $user->id)->get();
    $orders = [];
    foreach($products as $product){
        array_merge($orders, $product->order);
    }
    //dd( $products);
    return view('orders')->with(compact('orders'));
}

我需要每个列出产品的卖家（用户）在其他买家（用户）购买时收到订单。到目前为止它显示 "订单 ID 订单日期 客户姓名 客户城市 客户电话

在订单模型中，您与用户有关系，这意味着您拥有买家信息。 但是您与卖方没有任何关系。

所以为卖家添加一个关系。

注意：我假设买家和卖家都是User

您必须为买方和卖方添加关系（不要忘记将它们也添加到数据库中。这意味着您需要在orders table 上添加buyer_id 和seller_id 字段）。

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Order extends Model
{
     //protected $table = 'orders';
     protected $fillable =  [
        'buyer_id', 'seller_id', 'shipping_email', 'shipping_name', 'shipping_city',    'shipping_phone', 'billing_subtotal', 'billing_total',
     ];    


     public function products()
     {
         return $this->belongsToMany('App\Products_model')->withPivot('quantity');
     }

     public function orders(){
          return $this->hasMany('App\OrderProduct', 'order_id');
     }
     public function buyer()
     {
         return $this->belongsTo(User::class, 'id', 'buyer_id');
     }

     public function seller()
     {
         return $this->belongsTo(User::class, 'id', 'seller_id');
     }
  }

将这两个关系添加到 User 模型中。这样您就可以轻松地调用它们。

 public function buys() {
    $this->hasMany(Order::class, 'buyer_id', 'id');
 }
 public function sells() {
     $this->hasMany(Order::class, 'seller_id', 'id');
 }

//订单查看功能

public function viewOrders(User $user) {
    $products = Products_model::where('user_id', '=', $user->id)->get();
    // all sells
    $sells = $user->sells;
    // all buys
    $buys = $user->buys;

}

在视图中，你可以像这样循环，

@foreach($sells as $sell) 
    {{ $sell->orders }} //for orders.
    {{ $sell->products }} //for product
    @foreach($sell->orders as $order)
        {{ $order->product }} //single product
    @endforeach
@endforeach
