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