How to check the string only allow alpha and whitspace?

[vidago]

Hi,

I stuck in a problem, which check the string only accept alphabet and white space only.

I try

if (!eregi("^[[:alpha:]]{1,}$",$this->_thisValue)) {

but string like ''abc def' will return in false. Any idea? I want to accept string like 'abc dfds sdfsd'. 😕

Thanks

after spending an hour to find the solution, finally i got this with preg_match() :

if (!preg_match("/^[a-zA-Z.\s]{1,}$/",$this->_thisValue)) {

with a simple \s , it does solve all my problem! Bravo. 🆒
