Form Validation alpha_numeric spaces!!!

Does Form Validation not allow alpha_numeric_spaces!!!???

Spaces are not alphanumeric. The CI form_validation library
provides the basic validations. If the rule you need is not
available you can set up a callback function that validates
like you need it.

I tried replacing my alpha_numeric function in the form validation class with -

return ( ! preg_match(" /^[A-Za-z0-9\s]+$/i", $str)) ? FALSE : TRUE;

But didn't work

Why would you replace a rule when you can extend form validation with your own custom rules, or use a callback function? You shouldn't have to modify core CI files, which can lead to upgrade problems down the line. You extend the core so you don't have to touch the original files.
