Hi All,
Thankx for reading this.
I have a very newbie question...
i'm working on a CGI and i want only to permit some
caracters by the user...
imagine
my $STRING = "kjsh234Sd\nki";
# now i want to check if there is any invalid caracter
# in this case a-z ; A-Z and 0-9
there for /[a-zA-Z0-9]/ but i am unable to find a
valid command for that, the \n always passes, i
definity do not want to use execption on what o do not
allow, i want only to allow some caracters
invalidating all others...
here what i have tried
if ( $STRING =~ /[a-zA-Z0-9]/ ) { etc }
my $count = ( $STRING =~ tr /a-zA-Z0-9// );
all failed...
please help me :)
