Laravel 9 Request Validation with Custom Rules Not Triggering Correctly
I've been working on this all day and I'm having a hard time understanding I'm a bit lost with I'm working on a project and hit a roadblock. I'm currently working on a Laravel 9 application where I'm trying to implement custom validation rules for a form submission. Specifically, I have a form that accepts a user’s age and a subscription type. I want to ensure that if the subscription type is 'premium', the age must be at least 18. I set up my validation rules in the controller like this: ```php public function store(Request $request) { $request->validate([ 'age' => 'required|integer|min:0', 'subscription_type' => 'required|string', ]); // Custom rule to check age if ($request->subscription_type === 'premium' && $request->age < 18) { return redirect()->back()->withErrors([ 'age' => 'You must be at least 18 years old for premium subscription', ])->withInput(); } // Save the user here... } ``` However, the validation message doesn’t trigger even when the conditions are met. I tried placing the custom validation logic directly in the `validate` method using a closure, like so: ```php $request->validate([ 'age' => ['required', 'integer', 'min:0', function ($attribute, $value, $unexpected result) use ($request) { if ($request->subscription_type === 'premium' && $value < 18) { $unexpected result('You must be at least 18 years old for premium subscription.'); } }], 'subscription_type' => 'required|string', ]); ``` But this also doesn’t seem to work as expected. I've checked that the form data is coming through correctly in the `$request`, and I don't see any typos in the field names. I’ve also validated that the rules are applied before further processing. Is there something I might be overlooking here? Has anyone else encountered similar issues with custom validation in Laravel 9? Any guidance would be appreciated! This issue appeared after updating to Php LTS. I'm developing on Linux with Php. What are your experiences with this? Is there a simpler solution I'm overlooking?
