我很努力地找到一個合適的邏輯來更新Laravel中的這個數組。有了這個相同的邏輯,我可以創建,但我嘗試更新它只會更新數組的最後一行。感謝如何更新Laravel 5中的數組?
這裏是代碼
public function update(Request $request, $id)
{
$invoice = Invoice::findOrFail($id);
$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;
$invoice->save();
$products = $request->all();
$name = $products['name'];
$price = $products['price'];
$qty = $products['qty'];
$total = $products['total'];
foreach($name as $key => $n) {
$invoice->products()->update([
//=> $invoice->id,
'name' => $name[$key],
'price' => $price[$key],
'qty' => $qty[$key],
'total' => $total[$key]
]);
}
與此完全相同的代碼,我可以創建和工作正常,但如果我嘗試更新只更新數組中的最後一個記錄。
數據庫
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();
});
產品
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();
});

請添加一個調用update()到您的文章 –
是什麼$產品看起來像代碼?你可以print_r()或var_dump()嗎? –
產品更新功能是什麼? –
