如何将数组数据从 vuejs 传递到 laravel api 控制器

Question

我想通过 api 使用 vuejs 使用 laravel 制作发票系统。首先显示所有产品，当我点击添加到购物车时，它添加了。

截图如下：

现在我想将输入填充数据发送到 order_masters 表，包括最后插入的 ID 购物车数据发送 order_details 表。

但我不能传递整个数据。有时会传递客户信息，但不会传递购物车数据。

N。 B：我正在使用 vuejs、vform 和 API

我的组件代码如下：

<template>
<div class="row">
    <div class="col-md-7">
        <div class="col-md-11">
            <input type="hidden" v-model="field">
            <input type="search" v-model="query" class="form-control form-control-sm mb-3" placeholder="Search Here">
        </div>
        <div class="row justify-content-center">
            <div v-show="products.length" v-for="(product, id) in products" :key="id" class="card col-xl-3 col-md-3 col-sm-3 mb-5 mr-5 float-left" style="background-color:lightgray">
                <div class="card-body">
                    <h5 class="card-title">{{product.name}}</h5>
                    <p class="card-text"><input type="text" v-model="product.qty" class="form-control form-control-sm mb-2"></p>
                    <strong class="">
                           {{product.price}} TK
                        </strong>
                    <button class="btn btn-sm btn-primary float-right" @click="addToCart(product)">

        <div v-show="!products.length" class="alert alert-danger text-center" role="alert">

        </form>
    </div>

<script>
export default {
data(){
    return{
        field: 'name',
        query: '',
        form: new Form({
            'name': '',
            'phone': '',
            'address':'',
            'pro_id' : [],
            'qty' : [],
            'unit_price' : []
        }),
        products:[],
        carts:[],
        pagination:{
            current_page: 1
        }
    }
},
methods:{
    store(){
        var data = {
            carts: this.carts,
        }
        this.$Progress.start()
        this.form.busy = true
        this.form.post('api/pos', data)
            .then( res => {
                this.form.reset()
                this.form.clear()
                this.$Progress.finish()
                console.log(data)
            })
            .catch( e => {
                this.$Progress.fail()
                console.log(e)
            })

      }
  }
}
</script>

这里是 API 控制器功能：

public function store(Request $request)
{
    $carts = json_decode($request->getContent('data'), true);

     $this->validate($request,[
         'name' => 'required',
         'phone' => 'required',
         'address' => 'required'
     ]);

     $order = new OrderMaster;
     $order->name = $request->name;
     $order->phone = $request->phone;
     $order->address = $request->address;
     $order->save();

    $order_id = DB::getPdo()->lastInsertId();

    foreach ($carts as $cart) {

         OrderDetails::create([
             'order_id' => $order_id,
             'product_id' => ?,
             'qty' => ?,
             'unite_price' => ?,
         ]);
    }
}

Answer 1

首先，您调用 form.post 是错误的。第二个参数不是附加数据，而是axios.request调用的配置选项。

为了发送carts 数组，您应该将它添加到表单本身：

form: new Form({
  'name': '',
  'phone': '',
  'address':'',
  'pro_id' : [],
  'qty' : [],
  'unit_price' : [],
  'carts' : [], // <-- added
}),

然后，在您的模板（和方法）中将 carts 的用法替换为 form.carts。

现在，carts 将与其他数据一起发送到服务器。

最后，您根本不需要使用json_decode。

//...
$data = $this->validate($request, [
  'name' => 'required',
  'phone' => 'required',
  'address' => 'required',
  'carts' => 'required|array',
  'carts.*.name' => 'string',
  'carts.*.id' => 'integer',
  'carts.*.qty' => 'integer',
  'carts.*.price' => 'numeric',
]);

然后，您可以使用$data 作为数据源。

foreach ($data['carts'] as $cart) {
  OrderDetails::create([
    'order_id' => $order_id,
    'product_id' => $cart['id'],
    'qty' => $cart['qty'],
    'unite_price' => $cart['price'],
  ]);
}

Answer 2

我以其他方式完成了它。不使用 vform 我使用了 axios。但我想使用 vform 来完成。

return{
        field: 'name',
        query: '',
        form:{
            'name': '',
            'phone': '',
            'address':''
        },
        products:[],
        carts:[],
        pagination:{
            current_page: 1
        }
    }
store(){
        let client = {
            cli: this.form
        }
        let data = {
            carts: this.carts
        }

        this.$Progress.start()
        axios.post('api/pos', {data, client})
            .then( res => {
                this.$Progress.finish()
                console.log(res)
            })
            .catch( e => {
                this.$Progress.fail()
                console.log(e)
            })

    }

控制器：

$carts = json_decode($request->getContent('client','data'), true);

    $customer = $carts['client'];
    $pro_info = $carts['data'];

    foreach ($customer as $cus) {
        $order = new OrderMaster;
        $order->name = $cus['name'];
        $order->phone = $cus['phone'];
        $order->address = $cus['address'];
        $order->save();

    }

    $order_id = DB::getPdo()->lastInsertId();

    foreach ($pro_info as $cart) {
        foreach ($cart as $c) {
            OrderDetails::create([
                'order_id' => $order_id,
                'product_id' => $c['id'],
                'qty' => $c['qty'],
                'unit_price' => $c['price'],
            ]);
        }
    }
