Unexpected Null Value in Laravel 9 After Form Validation with Custom Rules
I've encountered a strange issue with I'm working on a project and hit a roadblock. After trying multiple solutions online, I still can't figure this out. I have a form in my Laravel 9 application that uses custom validation rules. Everything works fine until I try to access the validated data after the request passes through the validation. Specifically, when I check for the validated input, I find that certain fields are unexpectedly null, even though they were filled out correctly in the form. I defined the custom validation logic in a Form Request class, and my validation rules look something like this: ```php public function rules() { return [ 'name' => 'required|string|max:255', 'email' => 'required|email', 'age' => 'nullable|integer|min:0', 'custom_field' => 'required|custom_rule', ]; } ``` The custom rule is defined as follows: ```php public function passes($attribute, $value) { // Custom logic that sometimes returns null return $value === 'valid_value'; } ``` After the validation, I dump the validated data with `dd($this->validated())`, but I'm seeing this output: ```php array:4 [ "name" => "John Doe" "email" => "john@example.com" "age" => null "custom_field" => null ] ``` I expected `custom_field` to be filled, but it’s null because the custom validation rule is returning null due to the logic. I’m not sure how to handle this situation properly. Should I modify the custom validation rule, or is there a better way to make sure that `custom_field` retains its value if validation fails? Any suggestions would be greatly appreciated! Additionally, I've tried using the `withErrors` method to return specific behavior messages, but it seems like the validation fails completely when `passes` returns null, resulting in no data being present in the validated output. Is there a proper way to manage this scenario in Laravel? I'm working on a CLI tool that needs to handle this. Thanks in advance! Is there a better approach? This is for a desktop app running on Ubuntu 22.04. Thanks for your help in advance!
