Question

我从地址localhost / product / 1/1向我的数据库发送值时遇到问题，我想将产品1附加到客户1并在我添加代码的下方添加特殊价格

路线：

Route::get('/product/{customerID}/{productID}', 'CustomerController@insertCustomerProductForm')->name('add-product');
Route::post('/product/{customerID}/{productID}', 'CustomerController@insertCustomerProductAction');
to Controller

insertCustomerProductForm方法：

public function insertCustomerProductForm($customerID, $productID)

{       
       return view('customer_products.create', [
        'customer' => Customer::find('$customerID'),
        'product' => Product::find('$productID'),        ]);    }

insetCustomerProductAction方法：

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();    }

模拟CustomerProduct

class CustomerProduct extends Model
{
public function customers()

{
    return $this->belongsToMany(Customer::class);

}

public function products()

{
    return $this->belongsToMany(Product::class);

}}

，当我尝试使用客户产品的刀片设置值时，我仅从表单值（selling_customer_price ...等）中没有任何关于产品和客户的信息？我不知道为什么还是这种查找方法有问题？因为我必须以这种形式存储特殊客户的特殊价格。

在我下面添加刀片代码的一部分

@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>

我的错误看起来好像看不到表单中的变量：

selling_customer_price，purchase_customer_price，consumed_customer_price

我有错误：

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

两种情况下您的错误究竟出自哪里？只要您在网址中传递正确的参数，insertCustomerProductForm就能正常工作：localhost/product/20/10

POST请求通常不需要URL本身中的参数。您可以通过在$_POST['selling_customer_price']方法中执行insertCustomerProductAction来检索POST变量。

在Laravel中将值从Form和Controller传递给Blade的问题
