Laravel 8 data_fill() {#collection-method}

2021-07-19 10:19 更新

data_fill 函數(shù)使用「.」符號(hào)給多維數(shù)組或?qū)ο笤O(shè)置缺省值：

$data = ['products' => ['desk' => ['price' => 100]]];

data_fill($data, 'products.desk.price', 200);

// ['products' => ['desk' => ['price' => 100]]]

data_fill($data, 'products.desk.discount', 10);

// ['products' => ['desk' => ['price' => 100, 'discount' => 10]]]

這個(gè)函數(shù)也可以接收「*」 作為通配符，并設(shè)置相應(yīng)缺省值：

$data = [
    'products' => [
        ['name' => 'Desk 1', 'price' => 100],
        ['name' => 'Desk 2'],
    ],
];

data_fill($data, 'products.*.price', 200);

/*
    [
        'products' => [
            ['name' => 'Desk 1', 'price' => 100],
            ['name' => 'Desk 2', 'price' => 200],
        ],
    ]
*/
