我有這個陣列 cart_items,並且在映射到資料庫儲存(如程式碼中所示)時工作正常。
$cart_items = [ {"id":8, "cart_id":7, "product_id":4, "variation_id":null, "quantity":1, "price":30, "tax":0, "attrs":null, "gross_total":30, "net_total":30, "tax_total":0, "product":{ "id":4, "parent_id":null, "category_id":1, "shop_id":1, "title":"Ladies Blazer", "unit":"item", "sale_price":30, "general_price":35 } }, { "id":9, "cart_id":7, "product_id":1, "variation_id":null, "quantity":2, "price":11, "tax":0, "attrs":null, "gross_total":22, "net_total":22, "tax_total":0, "product":{ "id":1, "parent_id":null, "category_id":2, "shop_id":2, "title":"Sport Bottles", "unit":"item", "sale_price":11, "general_price":9 } } ]
$line_item_params = $cart_items->map(function (CartItem $item) { $p = [ 'product_id' => $item->product_id, //add filtered shop_id here 'variation_id' => $item->variation_id, 'product_title' => $item->product->title, 'quantity' => $item->quantity, 'price' => $item->price, 'tax' => $item->tax, 'attrs' => $item->attrs, ]; return $p; })->toArray();
我需要使用 Arr:where() 過濾數組,其中產品 shop_id 是特定值。
我嘗試使用 if 函數,但程式碼只是循環返回 true,其中存在 shop_id。
$line_item_params = $cart_items->map(function (CartItem $item) { if ($item->product['shop_id'] == 1){ $p = [ 'product_id' => $item->product_id, //add filtered shop_id here //'shop_id' => $shop->id, 'variation_id' => $item->variation_id, 'product_title' => $item->product->title, 'quantity' => $item->quantity, 'price' => $item->price, 'tax' => $item->tax, 'attrs' => $item->attrs, ]; } return $p; })->toArray();
我需要過濾產品shop_id為特定值的陣列。

我知道這個解決方案並不可取。那就太簡單了。您想使用 Laravel 9 元件來做到這一點。無論如何我都會告訴你:
$shop_id = 1; $result = array_filter($arr, fn($v) => $v["product"]["shop_id"] == $shop_id);
