刀片模板中的@php 标记无法访问内联变量

Question

I am looping through products which has all my configurable options available. Inside that i am looping through my items, when i get a match in product i want to display this product and item.

To do so i want to create a variable called $currentProduct.

@foreach($order['products'] as $product) // Configurable products
    @foreach($order['items'] as $item)  // Simple products
        @if ($item['product_type'] == 'simple')
            @if ($product['id'] === $item['product_id'])
                @php($currentProduct = $product) // error here $product undefined
                @php($currentItem = $item) // error here $item undefined
            @endif
        @elseif ($item['product_type'] == 'configurable')
            @if ($product['id'] == $item['parent_item']['product_id'])
                @php($currentProduct = $product) // error here $product undefined
                @php($currentItem = $item) // error here $item undefined
            @endif
        @endif
    @endforeach
@endforeach

I am new to laravel and blade templates and can't seem to wrap my head around, why $product and $item is undefined when they are defined right above in same template.

Any help appreciated

You put the code between @php and @endphp but without parantheses:

@foreach($order['products'] as $product) // Configurable products
    @foreach($order['items'] as $item)  // Simple products
        @if ($item['product_type'] == 'simple')
            @if ($product['id'] === $item['product_id'])
                @php
                    $currentProduct = $product;
                    $currentItem = $item;
                @endphp
            @endif
        @elseif ($item['product_type'] == 'configurable')
            @if ($product['id'] == $item['parent_item']['product_id'])
                @php
                    $currentProduct = $product;
                    $currentItem = $item;
                @endphp
            @endif
        @endif
    @endforeach
@endforeach

The variables can then be used below where they were defined.

See documentation about raw PHP in blade templates here:
https://laravel.com/docs/8.x/blade#raw-php

Answer 2

any @php must close with @endphp

Answer 3

Would you please try the below code? `

@foreach($order['products'] as $product)
    @foreach($order['items'] as $item)
        @if ($item['product_type'] == 'simple')
            @if ($product['id'] === $item['product_id'])
                @php ($currentProduct = $product) @endphp
                @php ($currentItem = $item) @endphp
            @endif
        @elseif ($item['product_type'] == 'configurable')
            @if ($product['id'] == $item['parent_item']['product_id'])
                @php ($currentProduct = $product) @endphp
                @php ($currentItem = $item) @endphp
            @endif
        @endif
    @endforeach
@endforeach
