如何在數據庫中插入多個輸入的數組？

Question

我正在插入多個輸入的數組。 但是當我dd或創建它時，它不會插入或返回任何值。 在這種情況下如何使用create？ 我是laravel的新手。

foreach ($data['sku'] as $key => $val) {


    $attrCountSKU = ProductsAttribute::where('sku', $val)->count();
    if ($attrCountSKU > 0) {
        return back()->with('error', 'SKU already exists for this product! Please input another SKU.');
    }

    $attrCountSizes = ProductsAttribute::where(['product_id' => $product->id, 'size' => $data['size'][$key]])->count();

    if ($attrCountSizes > 0) {
        return back()->with('error', 'Size already exists for this product! Please input another Size.');
    }


    $attribute = new ProductsAttribute;
    $attribute->product_id = $product->id;
    $attribute->sku = $val;
    $attribute->size = $data['size'][$key];


    $attribute->price = $data['price'][$key];
    $attribute->stock = $data['stock'][$key];

    dd($attribute);
    dd($attribute->create());
}

Answer 1

您需要使用save()方法保存模型。

在設置所有屬性后添加以下內容：

$attribute->save();

return $attribute->id // Will be set as the object has been inserted

您還可以使用create()方法一次性創建並插入模型：

$attribute = ProductsAttribute::create([
    'product_id' => $product->id,
    'sku' => $val,
    'size' => $data['size'][$key],
    'price' => $data['price'][$key],
    'stock' => $data['stock'][$key],
]);

Answer 2

而不是$attribute->create() ，應使用$attribute->save()方法。

或者使用create()方法，您可以像這樣

$flight = ProductsAttribute::create(
    [
        'product_id' => $product->id,
        'sku' => $val,
        'size' => $data['size'][$key],
        'price' => $data['price'][$key],
        'stock' => $data['stock'][$key],            
    ]
);
