# Uppercase
|
|
|
|
- `Uppercase()`
|
|
|
|
Validates whether the characters in the input are uppercase.
|
|
|
|
```php
|
|
v::uppercase()->validate('W3C'); // true
|
|
```
|
|
|
|
This rule 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.
|
|
|
|
```php
|
|
v::not(v::numericVal())->uppercase()->validate('42'); // false
|
|
v::alnum()->uppercase()->validate('#$%!'); // false
|
|
v::not(v::numericVal())->alnum()->uppercase()->validate('W3C'); // true
|
|
```
