Laravel 10: implementing Custom Validation Rules Not Triggering on Nested Requests
I'm having trouble with I'm deploying to production and Quick question that's been bugging me - I'm working with a question with custom validation rules in Laravel 10 that are supposed to be triggered on nested request data but don’t seem to work as expected. I have a form that submits data for a user profile, including nested address details. My validation rules are set up in the `FormRequest`, but the custom rule for validating the postal code within the address array isn't triggering. Here’s what my `UserProfileRequest` looks like: ```php namespace App\Http\Requests; use Illuminate\Foundation\Http\FormRequest; class UserProfileRequest extends FormRequest { public function rules() { return [ 'name' => 'required|string|max:255', 'email' => 'required|email', 'address.street' => 'required|string|max:255', 'address.city' => 'required|string|max:100', 'address.postal_code' => ['required', 'string', 'max:10', new PostalCodeRule()], ]; } } ``` The `PostalCodeRule` is a custom validation rule where I check for a specific pattern. Here’s the relevant part of that rule: ```php namespace App\Rules; use Illuminate\Contracts\Validation\Rule; class PostalCodeRule implements Rule { public function passes($attribute, $value) { return preg_match('/^\d{5}(-\d{4})?$/', $value); } public function message() { return 'The postal code must be a valid format.'; } } ``` When I test the request, if I send the following payload: ```json { "name": "John Doe", "email": "john@example.com", "address": { "street": "123 Main St", "city": "Anytown", "postal_code": "ABC123" } } ``` The validation fails, but I receive a generic behavior message that does not indicate which field caused the failure. I’ve debugged the request data and confirmed the nested structure is correct. I’ve tried manually triggering the validation by calling `validate()` directly in my controller, but the same scenario continues. Could there be something wrong with how Laravel interprets the nested validation rules or the custom rule itself? What am I missing here? I'm working on a web app that needs to handle this. Am I missing something obvious? This is part of a larger service I'm building.
