Handling custom validation rules in Laravel 8 for complex form inputs with dynamic fields
I've encountered a strange issue with I'm working on a project and hit a roadblock... I'm currently working on a form in Laravel 8 that allows users to enter data for multiple items dynamically. Each item can have a varying number of fields, and I need to implement custom validation rules based on the item's specific type. However, I'm running into issues where Laravel seems to ignore my custom validation logic under certain conditions. Here's a snippet of my form request validation: ```php public function rules() { $rules = []; foreach ($this->items as $index => $item) { $rules['items.' . $index . '.type'] = 'required|string'; $rules['items.' . $index . '.value'] = $this->getValueRules($item['type']); } return $rules; } protected function getValueRules($type) { switch ($type) { case 'text': return 'required|string|min:5'; case 'number': return 'required|numeric|min:1'; // more cases default: return 'nullable'; } } } ``` When I submit the form with a variety of item types, I get unexpected validation failures. For example, if I have an item of type 'text' and send a value shorter than 5 characters, the validation works as expected. However, if the item type is 'number' and I provide a valid number, I still receive validation errors stating that the value is required, even though it's provided. I've also tried debugging by logging the incoming request data and the validated data, but it seems like the validation rules for number fields are being applied incorrectly or not at all. I suspect it might have something to do with how Laravel processes the dynamic fields in the request. Could someone explain why this is happening? Is there a specific way I should structure my validation rules for dynamic fields in Laravel? Any insights or examples would be greatly appreciated! For context: I'm using Php on Ubuntu. What's the best practice here? I'm working on a application that needs to handle this.
