• Alpha()
  • Alpha(string ...$additionalChars)

Validates whether the input contains only alphabetic characters. This is similar to Alnum, but it does not allow numbers.

v::alpha()->validate('some name'); // false
v::alpha(' ')->validate('some name'); // true
v::alpha()->validate('Cedric-Fabian'); // false
v::alpha('-')->validate('Cedric-Fabian'); // true
v::alpha('-', '\'')->validate('\'s-Gravenhage'); // true

You can restrict case using the Lowercase and Uppercase rules.

v::alpha()->uppercase()->validate('example'); // false
