Laravel Validation one of two fields must be filled
提问by imperium2335
I have two fields:
我有两个字段：
电子邮件
How do I set up a Validator object so that one of these fields must be filled? It doesn't matter which.
如何设置 Validator 对象以便必须填写这些字段之一？哪个都无所谓。
$messages = array(
'email.required_without:qq' => Lang::get('messages.mustenteremail'),
'email.email' => Lang::get('messages.emailinvalid'),
'qq.required_without:email' => Lang::get('messages.mustenterqq'),
);

required_withoutshould work.
required_without应该管用。
It means that the field is required if the other field is not present. If have more than two fields and only one is required, use required_without_all:foo,bar,...
这意味着如果其他字段不存在，则该字段是必需的。如果有两个以上的字段并且只有一个是必需的，请使用required_without_all:foo,bar,...
$rules = array(
'Email' => 'required_without:QQ',
'QQ' => 'required_without:Email',
);

In the example above (given by lucasgeiter) you actually only need one of the conditions not both.
在上面的例子中（由 lucasgeiter 给出）你实际上只需要一个条件而不是两个。
$rules = array(
'Email' => 'required_without:QQ'
);
If you have both rules then filling neither in will result in TWO error messages being displayed. This way it will check that at least one field is filled in and will only display one error message if neither are filled.
如果您有这两个规则，那么填写任何一个都将导致显示两条错误消息。这样它会检查是否至少填写了一个字段，如果两者都没有填写，则只会显示一条错误消息。
