Question

这里我有一个多维使用这个数组<a *ngFor="let link of item.ReferenceMaterials|split" href="{{link}}">{{link}}</a>明智地我再制作一个数组，从这个数组我有productId数组，从这里我必须取Galery prodcutImage值，如果有任何人更新我的asnwer

，我不知道如何实现这个目标

我有像这样的数组

first

我试过这样的

print_r($productByCode)

    Array
(
    [0] => Array
        (
            [productId] => 5
            [adminproductId] => 1Delivery00123
            [categoryName] => Computer Accessories
            [brandName] => Dell
            [title] => Dell Inspiron 5000 Series 5547 5555 5557 5558 Internal Laptop Keyboard  (Black)
            [subTitle] => Dell Keyboard
            [price] => 200
            [discountType] => Percentage
            [discountValue] => 20
            [afterDiscount] => 160
            [shipppingAmount] => 150
            [taxPercentage] => 25
            [Galery] => Array
                (
                    [0] => Array
                        (
                            [gId] => 13
                            [productId] => 5
                            [prodcutImage] => 1.jpeg
                        )

                    [1] => Array
                        (
                            [gId] => 14
                            [productId] => 5
                            [prodcutImage] => 2.jpeg
                        )

                    [2] => Array
                        (
                            [gId] => 15
                            [productId] => 5
                            [prodcutImage] => 3.jpeg
                        )
                )
        )
)

当前输出

$itemArray = array
(
  $productByCode[0]["productId"]=>array
  (
    'categoryName'=>$productByCode[0]["categoryName"], 
    'productId'=>$productByCode[0]["productId"], 
    'brandName'=>$productByCode[0]["brandName"], 
    'subTitle'=>$productByCode[0]["subTitle"], 
    'quantity'=>$Qty_total,
    'price'=>$productByCode[0]["afterDiscount"],
    'taxPercentage'=>$productByCode[0]["taxPercentage"].'%',
    'shipppingAmount'=>$productByCode[0]["shipppingAmount"],
    'qtyprice'=>round($productByCode[0]["afterDiscount"])
  )
);

预期输出

    Array
(
    [5] => Array
        (
            [categoryName] => Computer Accessories
            [productId] => 5
            [brandName] => Dell
            [subTitle] => Dell Keyboard
            [quantity] => 1
            [price] => 160
            [taxPercentage] => 25%
            [shipppingAmount] => 150
            [qtyprice] => 160
        )

)

如果我理解了您的要求，您已经尝试过这样的方式将值分配给不同的数组元素，所以只需使用嵌套数组元素访问方式＆amp;获取 Galery 值。在数组的最后添加此元素。

'prodcutImage' => $productByCode[0]['Galery'][0]['prodcutImage']

所以它会喜欢这个，

$itemArray = array
(
$productByCode[0]["productId"]=>array
(
    'categoryName'=>$productByCode[0]["categoryName"], 
    'productId'=>$productByCode[0]["productId"], 
    'brandName'=>$productByCode[0]["brandName"], 
    'subTitle'=>$productByCode[0]["subTitle"], 
    'quantity'=>$Qty_total,
    'price'=>$productByCode[0]["afterDiscount"],
    'taxPercentage'=>$productByCode[0]["taxPercentage"].'%',
    'shipppingAmount'=>$productByCode[0]["shipppingAmount"],
    'qtyprice'=>round($productByCode[0]["afterDiscount"]),
    'prodcutImage' => $productByCode[0]['Galery'][0]['prodcutImage']
  )
);
