  • Uppercase()

Validates whether the characters in the input are uppercase.

v::uppercase()->assert('W3C');
// Validation passes successfully

This validator does not validate if the input a numeric value, so 123 and % will be valid. Please add more validations to the chain if you want to refine your validation.

v::not(v::numericVal())->uppercase()->assert('42');
// → "42" must not be numeric

v::alnum()->uppercase()->assert('#$%!');
// → "#$%!" must consist only of letters (a-z) and digits (0-9)

v::not(v::numericVal())->alnum()->uppercase()->assert('W3C');
// Validation passes successfully
