使用自定义规则的Laravel数组验证

Question

In CustomFormRequest i have something like this:

public function rules(): array
{
    return [
        'events' => ['array'],
        'events.*.type' => ['required'],
        'events.*.data' => [app(SomeRule::class)],
    ];
}

SomeRule :

public function passes($attribute, $value): bool
{
    var_dump($attribute);//events.0.data
    var_dump($value);exit;
}

In SomeRule::passes i need to have access to events.X.type (so for events.5.data i need events.5.type ). Any ideas?

As a user commented in my question Validating array in Laravel using custom rule with additional parameter , you can do it with this code, in your case it would be something like

class SomeRule implements Rule
{
    public function passes($attribute, $value)
    {
        $index = explode('.', $attribute)[1];
        $type = request()->input("events.{$index}.type");

        return someConditional ? true : false;
    }
}
