Re: eregi and alfa numeric characters.

Hi Sait, > no characters except for the followings will not be allowed. > 0-9 a-z A-Z ~ @ # $ % ( ) _ - + = [ ] { } < ? > if ( ereg("[^0-9a-zA-Z\_\-]", $user_input) ) { //invalid char detected } else { //input contain only allowed char } just add all your valid char in the pattern, and dont forget to escape the char which has special meaning in regex. -- Jimmy ~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Money is what you make it - a servant or a master
