Alnum

• Alnum()
• Alnum(string ...$additionalChars)

Validates whether the input is alphanumeric or not.

Alphanumeric is a combination of alphabetic (a-z and A-Z) and numeric (0-9) characters.

v::alnum()->isValid('foo 123'); // false
v::alnum(' ')->isValid('foo 123'); // true
v::alnum()->isValid('100%'); // false
v::alnum('%')->isValid('100%'); // true
v::alnum('%', ',')->isValid('10,5%'); // true

You can restrict case using the Lowercase and Uppercase validators.

v::alnum()->uppercase()->isValid('example'); // false

Message template for this validator includes {{additionalChars}} as the string of extra chars passed as the parameter.
