Small adjustment

I want to create some PHP validation for my Name input box on my form

For my Username input box, i have

if (preg_match('/^[a-z0-9_]{5,20}$/i', $username))

PHP:

This checks that the username is 5 - 20 characters in length and that a-z 0-9 _ characters are only used

How do i create a validation similar to above that only checks that the name input box is 1-20 characters in length (any characters can be used)

Thanks

 

Hmm, short of adding all the characters aI'm not too sure.

You could always use strlen instread

if ((strlen($username)>=1) AND (strlen($username)<=20))
{
Validate
}
else
{
error
}

etc.

 

or :

if (preg_match('/^.{1,20}$/i', $username))

PHP:
