laravel validation custom-rules PHP

I'm a bit lost with I just started working with I've spent hours debugging this and I've looked through the documentation and I'm still confused about I'm working with a question with implementing a custom validation rule in Laravel 10 that should only apply under certain conditions. I've created a custom rule to check if an input is required based on the value of another input field. However, the validation isn't behaving as expected. For example, if the user selects 'Yes' in a dropdown, another input should be required, but if 'No' is selected, it shouldn't. I set up the validation in my controller like this: ```php public function store(Request $request) { $request->validate([ 'dropdown' => 'required|in:yes,no', 'conditional_input' => ['required_if:dropdown,yes'], ]); // Proceed with storing data... } ``` I'm getting a validation behavior for `conditional_input` even when I select 'No' in the dropdown. I checked the request data and it shows the correct value, but the validation seems to be triggered regardless of the dropdown selection. I've also tried using the `sometimes` method, but that didn't help either. Here’s what my request data looks like when I'm submitting: ```json { "dropdown": "no", "conditional_input": "" } ``` I expected the validation to pass since the dropdown value is 'No', but it still fails for `conditional_input`. I've double-checked my form and I’m passing the correct values from the frontend. Any ideas on what might be going wrong or how to debug this? What could be causing this unexpected behavior? Has anyone else encountered this? Am I missing something obvious? Any help would be greatly appreciated! What would be the recommended way to handle this? What are your experiences with this?
