Validating Matching Strings
提问by Neel
When I use the Validation feature in Laravel, how can I add a pre-defined strings that are allowed in an Input?
当我在 Laravel 中使用验证功能时，如何添加允许在输入中使用的预定义字符串？
For example, let's say I want the Input to contain only one of the following: foo,bar,baz, how can I do that?
例如，假设我希望 Input 仅包含以下内容之一：foo,bar,baz，我该怎么做？
$validator = Validator::make($credentials, [
'profile' => 'required|max:255', // Here I want Predefined allowed values for it
]);

Best to use the 'in' validation rule like this:
最好像这样使用“in”验证规则：
$validator = Validator::make($credentials, [
'profile' => ["required" , "max:255", "in:foo,bar,baz"]
]);

It is recommended in Laravel docs to put the validation rules in an array when they get bigger and I thought 3 rules were sufficient. I think it makes it for a more readable content but you do not have to. I added the regexportion below and I have it works. I am not that great with regexing stuff. Let me know.
Laravel 文档中建议在验证规则变大时将它们放入数组中，我认为 3 条规则就足够了。我认为它使内容更具可读性，但您不必这样做。我添加了regex下面的部分，我有它的工作。我不太擅长正则表达式。让我知道。
$validator = Validator::make($credentials, [
'profile' => ["required" , "max:255", "regex:(foo|bar|baz)"]
]);
