Alnum
v::alnum()
v::alnum(string $additionalChars)
Validates alphanumeric characters from a-Z and 0-9.
v::alnum()->validate('foo 123'); // true
v::alnum()->validate('number 100%'); // false
v::alnum('%')->validate('number 100%'); // true
Because this rule allows whitespaces by default, you can separate additional characters with a whitespace:
v::alnum('- ! :')->validate('foo :- 123 !'); // true
This validator allows whitespace, if you want to
remove them add ->noWhitespace()
to the chain:
v::alnum()->noWhitespace()->validate('foo 123'); // false
You can restrict case using the ->lowercase()
and
->uppercase()
validators:
v::alnum()->uppercase()->validate('aaa'); // false
Message template for this validator includes {{additionalChars}}
as
the string of extra chars passed as the parameter.
