Question

我有一个表单，它将数据提交给2个单独的模型。

SalesItem模型属于Sale。销售可以有许多SalesItems。

我知道我需要将重复的字段放入数组中，但我并不完全确定应该如何去做。虽然我有正确的想法，但我的控制器并没有抓住数组作为我试图将其设置为的变量。

非常感谢所有帮助！

/*** Sale Model  ***/
    class Sale extends \Eloquent {
    public function user(){
        return $this->belongsTo('User');
    }

    public function salesItem()
    {
        return $this->hasMany('SalesItem');
    }

    }

/*** SalesItem Model ***/
    class SalesItem extends \Eloquent {
        protected $table = 'SalesItems';

    public function sale()
    {
        return $this->belongsTo('Sale');
    }
    }

/**** SalesController@store ****/
    public function store()
    {
        $sale = new Sale();
        if(Auth::user()){
            $userID = Auth::user()->id;
            $sale->user_id = $userID;
        }
        $sale->invoice_number = Input::get('invoice_number');
        $sale->name_of_purchaser = Input::get('name_of_purchaser');
        $sale->date_of_sale = Input::get('date_of_sale');


        // For each saleItem that exists
        foreach($items as $item)
        {
            //Create new salesitem
            $saleItem = new SalesItem();
            //Save attributes 
            $saleItem->product_id = $item['equipment'];
            $saleItem->selling_price = $item['selling_price'];
            $saleItem->serial_number = $item['serial_number'];
            $saleItem->save();

            //associate with the sale
            $sale->salesItem()->associate($salesItem);
        }
        $sale->save();

        return "Sale Saved";
    }

你的代码中有一些错误，但我会尝试给你一个方向..

用以下内容替换输入字段：

{{ Form::text('items[0]["equipment"]', array('class' => 'form-control clone'))}} 
.... 
{{ Form::text('items[0]["selling_price"]', array('class' => 'form-control clone'))}}
....

使用$items = Input::get('items');抓取项目（顺便说一下，这是php发出错误的一点：你从来没有从请求中获得$ items）

迭代items数组并将其中的每一个添加到Sale模型中。

在Laravel中重复表单字段
