Which method allows checking if a specific field is present in the request?
Odpowiedź
The has() method checks if one or more fields are present in the request and contain a non-empty value. It returns a boolean. To simply check for field presence even if empty, use filled() which checks the field exists AND is not empty, or exists() to only check presence without validating the value.
3Which method allows retrieving all request fields as an array?
Which method allows retrieving all request fields as an array?

The all() method returns all request data as an associative array. Unlike only() which filters specific fields, or except() which excludes certain fields, all() returns all submitted data. This method is useful for passing all data to validation or for global processing.
