Question

如果有几个问题显示带有排名的选择ID（选择第一个复选框为首选，等等）。这是通过以下形式发送的简化的var_dump($_POST)：

Array
(
    [_token] => 6vPgIM1MX7MJ0DzMX2OFjCdPEBBel5mRJ6RzrEjR
    [11] => Array // Means question id 11
        (
            [42] => 2 // Means choice id 42 was chosen second
            [43] => 1 // Means choice id 43 was chosen first
            [44] => 3 // Means choice id 44 was chosen third
        )

    [12] => 

    [13] => Array
        (
            [4] => 1
        )

    [btn-validate] => CONTINUE
)

然后我的var_dump($validationRules)如下：

Array
(
    [11] => Array
        (
            [0] => between:0,2
        )

    [12] => Array
        (
            [0] => between:1,3
        )

    [13] => Array
        (
            [0] => between:0,1
        )
)

最后是var_dump($validationMessages)（但在这里没有那么重要）：

Array
(
    [11.between] => You should select between 0 and 2 choices
    [12.between] => You should select between 1 and 3 choices
    [13.between] => You should select between 0 and 1 choices
)

这都是这样包裹的：

$validator = Validator::make($request->all(), $validationRules, $validationMessages);

if ($validator->fails()) {
    var_dump($validator->errors());
    exit('fail'); // Never ends up here
}
exit('all good'); // Always ends up here

如何使between:x,y验证规则与值数组一起使用？

Answer 1

我认为您误解了数组之间的规则是如何工作的。

来自between rule docs：

（...）字符串，数字，数组和文件的计算方式与大小规则相同。

来自size rule docs：

（...）对于数组，大小对应于数组的计数。（...）

意味着您指定的验证规则意味着将评估每个数组值的计数。在每种情况下，由于每种情况下的计数均为1，这些值均被评估为true。

Answer 2

将此作为您的复选框 //刀片文件

<div class="form-group">
    <label for="likes_turtles" class="col-md-3 control-label">Likes Turtles</label>
    <div class="col-md-6">
        <div class="checkbox">
            <label>
                <input type="checkbox" name="likes_turtles[]" value="Yes"> Yes
            </label>
        </div>
        <div class="checkbox">
            <label>
                <input type="checkbox" name="likes_turtles[]" value="No"> No
            </label>
        </div>
        <div class="checkbox">
            <label>
                <input type="checkbox" name="likes_turtles[]" value="Maybe so"> Maybe so
            </label>
        </div>
    </div>
</div>

然后您就可以在控制器中进行验证，例如下面的代码

[
    "likes_turtles" => "required", 
    "likes_turtles.*" => "in:Yes,No,Maybe so"
]

Answer 3

找出问题所在。

我所有的规则都还可以，问题是Laravel的验证系统不支持将整数用作$_POST键

Laravel问题： https://github.com/laravel/framework/issues/29116

复选框数组的“之间”验证规则始终有效
