ereg() help

[Northern Flame]

i found a string that you can place into the ereg function

and used it for my usernames when a user registers to my

site, the string works fine except it doesnt allow my users

to enter numbers in their username, im not too good with

understanding these kinds of patters so can someone help

me edit this string so that i can accept numbers too?

 

i know it has something to do with the "digit" but i dont

know if i have to take out digit, :digit:, [:digit:], or [[:digit:]]

and i dont want to mess up the string so can someone help

me?

 

heres me string:

 

$pattern = '([[:digit:]]|[~`!@#$%^&*(). =+<>{}|\:;"/?,]|[|]|-)+';

personally i use preg_match,

 

if you want to verify if a string is only numbers/letters then you could use:

 

preg_match("/\A[a-zA-Z0-9]{6,16}$/i",$string);

 

this would return 1 if the string is only letters/numbers and is between 6-16 characters long.

--------

preg_match("/\A[a-zA-Z0-9\.]{6,16}$/i",$string);

same as above but also allows . (periods)

------------

preg_match("/\A[a-zA-Z0-9\._-]{6,16}$/i",$string);

same as above but allows periods, dashes and underscores.

------------

preg_match("/\A[a-zA-Z0-9\._ -]{6,16}$/i",$string);

same as above but allows periods, dashes and underscores and spaces.

------------

preg_match("/\A[a-zA-Z0-9_-]{6,16}$/i",$string);

same as above but allows dashes and underscores.

-----------

 

 

If the string does not match it will return 0.

 

 

 

hope this helps,
