使用自定义规则的Laravel数组验证 [英] Laravel array validation with custom rule

问题描述

在CustomFormRequest中，我有这样的内容:

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;
}

在SomeRule::passes中，我需要访问events.X.type(因此对于events.5.data，我需要events.5.type).有什么想法吗?

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;
    }
}
