Validation 与其他字段一起输入所需地址

我试图在一个表单上输入验证，其中不需要用户的完整地址，除非填写了其中一个地址字段

示例：如果我填写州或城市输入字段，那么我还需要填写邮政编码和街道地址

我试着用Laravel的

required\u搭配

，

required\u搭配

和

required\u如果

的话，但它们似乎都不起作用。有什么建议吗

我也遇到了同样的问题，但现在我找到了解决问题的方法，下面是错误的代码：

$rules = [
    ...
    /** address optional */
    'address-id' => 'exists:addresses, id', 
    'address-complement' => '', 

    /** address required */
    'address-state-id' => 'required_with:address-id, address-city-id, address-postal_code, address-street, address-number, address-complement, address-district', 
    'address-city-id' => 'required_with:address-id, address-state-id, address-postal_code, address-street, address-number, address-complement, address-district', 
    'address-postal_code' => 'required_with:address-id, address-city-id, address-state-id, address-street, address-number, address-complement, address-district', 
    'address-street'  => 'required_with:address-id, address-city-id, address-postal_code, address-state-id, address-number, address-complement, address-district', 
    'address-number' => 'required_with:address-id, address-city-id, address-postal_code, address-street, address-state-id, address-complement, address-district', 
    'address-district' => 'required_with:address-id, address-city-id, address-postal_code, address-street, address-number, address-complement, address-state-id', 
    ...
];

下面是正确的答案：

$rules = [
    ...
    /** address optional */
    'address-id' => 'exists:addresses,id',
    'address-complement' => '',

    /** address required */
    'address-state-id' => 'required_with:address-id,address-city-id,address-postal_code,address-street,address-number,address-complement,address-district',
    'address-city-id' => 'required_with:address-id,address-state-id,address-postal_code,address-street,address-number,address-complement,address-district',
    'address-postal_code' => 'required_with:address-id,address-city-id,address-state-id,address-street,address-number,address-complement,address-district',
    'address-street'  => 'required_with:address-id,address-city-id,address-postal_code,address-state-id,address-number,address-complement,address-district',
    'address-number' => 'required_with:address-id,address-city-id,address-postal_code,address-street,address-state-id,address-complement,address-district',
    'address-district' => 'required_with:address-id,address-city-id,address-postal_code,address-street,address-number,address-complement,address-state-id',
    ...
];

我必须删除逗号后的空格才能使其正常工作。

required\u与
一起使用的？请展示你所做的尝试
