Laravel array validation with custom rule

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?

hmm... but i need to get index from events.0.data. Is better way to do that than explode? — Bolek Lolek

maybe review your validation to do 'events.*' => [app(SomeRule::class)], and then $value should have both type and data (maybe, I don't know if it will work) — apokryfos

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;
    }
}
