I made contact form in Laravel. some of input field are just normal input field. And rest of them are JS generate data which are 'product', 'quantity' and 'price'. I can store ONLY normal input field data.
Here is my dd() image.
And this is my blade file.
<select id="product" name="product" onchange="caliculate()"></select>
<input id="v_product" type="hidden" name="product">
Controller
//Store data in database
Contact::create($request->all());
Could you teach me how to store product, quantity and price data into Mysql please?

nameattributes for your fields
