how to get order item sales report in laravel? - php

Question

I'm trying to get last month order items report. Here is my table structure
orders
id - integer
amount- double
order_items (pivot table)
id - integer
order_id - foreign
item_id - foreign
quantity
price
Here is my Item model
public function orders()
{
return $this->belongsToMany(Order::class, 'order_items', 'item_id', 'order_id')
->withPivot('quantity', 'price');
}
Here is my Order model
public function items()
{
return $this->belongsToMany(Item::class, 'order_items', 'order_id', 'item_id')
->withPivot('quantity', 'price')
->withTimestamps();
}
Here is my controller where I got last month's all orders
$orders = Order::with('items')
->whereMonth('created_at', '=', Carbon::now()->subMonth()->month)
->get();
After foreach loop in blade,
#foreach ($orders as $order)
<ul>
#foreach($order->items as $item)
<li>
{{ $item->name }}, {{ $item->pivot->quantity }}, {{ $item->pivot->price }}
</li>
#endforeach
</ul>
<hr>
#endforeach
I'm getting data like this
Item Name Quantity Price
Item A 20 600
Item A 15 400
Item A 5 200
Item B 5 100
Item B 5 100
But I don't want to show same item in this row, I want to show like this
Item Name Quantity Price
Item A 40 1200
Item B 10 200
How to sum quantity and price if item is same?

Answer 1

I think this could solve your problem:
$orders = Order::with('items')
->whereMonth('created_at', '=', Carbon::now()->subMonth()->month)
->get();
$orders->transform(function($order){
$itemsArray = [];
$order['items'] = $order['items']->groupBy('name')->map(function ($item) use ($itemsArray){
array_push($itemsArray, [
'name' => $item[0]['name'],
'qty' => $item->sum('qty'),
'price' => $item->sum('price')
]);
return $itemsArray[0];
})->values();
return $order;
});
