Question

我需要一些帮助，从同一表格插入数据库发票和产品。我犯了很多错误。

发票数据库：

Schema::create('invoices', function (Blueprint $table) {
    $table->increments('id');
    $table->integer('invoice_no');
    $table->date('invoice_date');
    $table->date('due_date');
    $table->string('title');
    $table->string('client');
    $table->string('client_address');
    $table->decimal('subtotal');
    $table->decimal('grandtotal');
    $table->timestamps();
});

产品数据库：

Schema::create('products', function (Blueprint $table) {
    $table->increments('id');
    $table->integer('invoice_id')->unsigned();
    $table->string('name');
    $table->string('qty');
    $table->string('price');
    $table->string('total');
    $table->timestamps();
});

发票模型：

protected $fillable = [
    'client',
    'client_address',
    'title',
    'invoice_no',
    'invoice_date',
    'due_date',
    'discount',
    'subtotal',
    'grandtotal'
];

产品型号：

public function products() {
    return $this->hasMany('App\Product', 'invoice_id');
}

protected $casts = [
    'name' => 'array',
    'price' => 'array',
    'qty' => 'array',
    'total' => 'array'
];

protected $fillable = ['invoice_id','price','qty','total','name'];

public function invoice() {
    return $this->belongsTo('App\Invoice');
}

发票控制器：

$invoice = new Invoice();
$invoice->invoice_no = $request->invoice_no;
$invoice->client = $request->client;
$invoice->title = $request->title;
$invoice->client_address = $request->client_address;
$invoice->invoice_date = $request->invoice_date;
$invoice->due_date = $request->due_date;
$invoice->subtotal = $request->subtotal;
$invoice->grandtotal = $request->grandtotal;

$input = $request->all();
$product = new Product();
$product->name = $input['name'];
$product->price = $input['price'];
$product->qty = $input['qty'];
$product->total = $input['total'];

$invoice->save();
$product->invoice_id = $invoice->id;
$invoice->products()->save($product);

Answer 1

您的发票上有很多产品。所以，首先创建发票

$invoice = \Invoice::create([
    'invoice_no' => $request->invoice_no,
    'client' => $request->client,
    'title' => $request->title,
    'client_address' => $request->client_address,
    'invoice_date' => $request->invoice_date,
    'due_date' => $request->due_date,
    'subtotal' => $request->subtotal,
    'grandtotal' => $request->grandtotal
]);

然后，添加其产品

$product = $invoice->products()->create([        
    'name' => $request->name,
    'price' => $request->price,
    'qty' => $request->qty,
    'total' => $request->total
])

如果您有多个产品，请将产品创建放在foreach循环中。

如何管理产品的插入，取决于您的表单结构。在接下来，我将举例说明整个过程。

我认为这是你的形式：

<form>                                
    <div class="product">
        <input name="products[0][name]" >
        <input name="products[0][price]" >
        <input name="products[0][qty]" >
        <input name="products[0][total]" >            
    </div>

    <div class="product">
        <input name="products[1][name]" >
        <input name="products[1][price]" >
        <input name="products[1][qty]" >
        <input name="products[1][total]" >            
    </div>

    <div class="product">
        <input name="products[2][name]" >
        <input name="products[2][price]" >
        <input name="products[2][qty]" >
        <input name="products[2][total]" >            
    </div>

    <button type="submit" >Submit</button>    
</form>

提交表单后，您将拥有一系列产品：

$request->products

返回

[
    [
        'name' => 'some name',
        'price' => '10',
        'qty' => '2',
        'total' => '20',
    ], [
        'name' => 'some name',
        'price' => '10',
        'qty' => '2',
        'total' => '20',
    ], [
        'name' => 'some name',
        'price' => '10',
        'qty' => '2',
        'total' => '20',
    ],
]

现在您可以将它们插入数据库中，如下所示：

foreach($request->products as $product) {
    $invoice->products()->create([        
        'name' => $product['name'],
        'price' => $product['price'],
        'qty' => $product['qty'],
        'total' => $product['total']
    ]);
}

OR

foreach($request->products as $product) {
    $invoice->products()->create($product);
}
