Question

美好的一天，我正在为我的学习做推车订单服务 API 。我正在努力解决如何检查多件物品的问题。

第一个问题

我不知道如何将一个数组（像下面的输出一样）从post请求传递给我的控制器或方法。用户完成选择他/她的项目后。

第二

如何实现数组（类似于下面的输出）

当用户1234选择1项时，输出将如下所示。

Array ( [user_id] => 1234 
        [0] => Array ( 
                        [product_id]    => 123 
                        [product_name]  => sample product 1 
                        [product_desc]  => A sample product 
                        [product_price] => 100 
                    ) 
        )

当用户1234选择2个项目时。这将是输出。

Array ( [user_id] => 1234 
        [0] => Array ( 
                        [product_id]    => 1 
                        [product_name]  => sample product 1 
                        [product_desc]  => A sample product 
                        [product_price] => 100 
                    ) 
        [1] => Array ( 
                        [product_id]    => 2 
                        [product_name]  => sample product 2 
                        [product_desc]  => A sample product 
                        [product_price] => 100 
                    ) 
        )

当用户12选择2个项目时。这将是输出。

Array ( [user_id] => 12 
        [0] => Array ( 
                        [product_id]    => 1
                        [product_name]  => sample product 2 
                        [product_desc]  => A sample product 
                        [product_price] => 100 
                    ) 
        [1] => Array ( 
                        [product_id]    => 2 
                        [product_name]  => sample product 2 
                        [product_desc]  => A sample product 
                        [product_price] => 200 
                    ) 
        )

已编辑这是我的测试结帐表单。目前它只能一次结账单项。

<form action="/test/api/checkoutItem" method="POST">
    <input type="hidden" name="cart_items_id" id="cart_items_id" value="55">
    <input type="hidden" name="user_id" id="user_id" value="11647748">
    <input type="hidden" name="product_id" id="product_id" value="70">
    <input type="input"  name="qty" id="qty">
</form>

控制器

{ 
    $id     = $request->user_id;
    //Status TESTED AND OK.
    try{
        //Check if cart has an item whith status id 1 (Added).
        $cart = \DB::table('cart_items')
                ->whereRaw('cart_items.id = ' .$request->cart_items_id. 
                    ' AND cart_items.product_id = ' .$request->product_id.

很抱歉这个愚蠢的问题。

PHP处理POST和GET变量的一个特点就是它自动解码索引形式的变量名称。

你可以这样做

<form ....>
<input name="person[userId]" value="1234" />
<input name="person[0][product_id]" value="1" />
<input name="person[0][product_name]" value="sample product 1" />
...
<input name="person[1][product_id]" value="2" />
<input name="person[1][product_name]" value="sample product 2" />
</form>

在php中，您可以通过以下方式检索它：

<?php
var_dump($_POST['person']);
//will get you something like:
    [user_id] => 1234
    [0] => Array ( 
              [product_id]    => 1
              [product_name]  => sample product 1 
          ) 
    [1] => Array ( 
              [product_id]    => 2 
              [product_name]  => sample product 2 
          ) 
?>
