Issue with passing values from Form and Controller to Blade in Laravel - laravel

Question

I have issue with send values from address localhost/product/1/1 to my database, I want attach product 1 to customer 1 and add special prices below I add code
Route:
Route::get('/product/{customerID}/{productID}', 'CustomerController#insertCustomerProductForm')->name('add-product');
Route::post('/product/{customerID}/{productID}', 'CustomerController#insertCustomerProductAction');
to Controller
insertCustomerProductForm method:
public function insertCustomerProductForm($customerID, $productID)
{
return view('customer_products.create', [
'customer' => Customer::find('$customerID'),
'product' => Product::find('$productID'), ]); }
insetCustomerProductAction method:
public function insertCustomerProductAction (Request $request, $customerID, $productID) {
$newCustomerProduct = new CustomerProduct;
$newCustomerProduct->product_id = $productID;
$newCustomerProduct->customer_id = $customerID;
$newCustomerProduct->selling_customer_price = $request->input('selling_customer_price');
$newCustomerProduct->purchase_customer_price = $request->input('purchase_customer_price');
$newCustomerProduct->consumed_customer_price = $request->input('consumed_customer_price');
$newCustomerProduct->save(); }
Model CustomerProduct
class CustomerProduct extends Model
{
public function customers()
{
return $this->belongsToMany(Customer::class);
}
public function products()
{
return $this->belongsToMany(Product::class);
}}
and when I try use in blade set values for product of customer I have only from form values (selling_customer_price... etc) nothing about product and customer? I don't know why or this find method is problem? Because I have to store special price for special customer in this form.
below I add part of blade code
#extends('layouts.app')
#section('content')
<div class="container">
<div class="row justify-content-center">
<div class="col-md-8">
<div class="card">
<div class="card-header">{{ __('Dodaj Produkt') }} </div>
<div class="card-body">
<form method="post">
#csrf
<div class="form-group row">
{{ $customer }}
<label for="selling_customer_price " class="col-md-4 col-form-label text-md-right">{{ __('Cena Sprzedaży') }}</label>
<div class="col-md-6">
<input id="selling_customer_price " type="text" class="form-control{{ $errors->has('selling_customer_price ') ? ' is-invalid' : '' }}" name="selling_customer_price " value="" required autofocus>
#if ($errors->has('selling_customer_price '))
<span class="invalid-feedback" role="alert">
<strong>{{ $errors->first('selling_customer_price ') }}</strong>
</span>
#endif
</div>
my error looking like it don't see variables from form:
selling_customer_price, purchase_customer_price, consumed_customer_price
I have error:
SQLSTATE[23000]: Integrity constraint violation: 1048 Column 'selling_customer_price' cannot be null (SQL: insert into `customer_products` (`product_id`, `customer_id`, `selling_customer_price`, `purchase_customer_price`, `consumed_customer_price`, `updated_at`, `created_at`) values (1, 1, , , , 2018-07-09 12:39:03, 2018-07-09 12:39:03))

Answer 1

Where exactly is your error coming from in both cases? insertCustomerProductForm should be working fine, as long as you pass the right parameters in the URL like so: localhost/product/20/10
POST request generally don't need parameters in the URL itself. You can retrieve the POST variables by doing $_POST['selling_customer_price'] in your insertCustomerProductAction method.
