My input validate for ALPHABET characters is not working

[Gmans]

Hi I have a lot of input validation in my script.

The first to see if the input field is empty is function ok.
if ($first=="") {$error.="First name is missing. ";}

But the second one here is not.

if ($first!=ctype_alpha) {$error.="Your have to use ALPHABET characters only."; }

I have tryed to write this: ($first!='ctype_alpha') and this: ($first!="ctype_alpha") but notting works.
🙁 Only if I type the exact word ctype_alpha in the input field I don't get an error.

Please help, thanks

take a look at the php documentation for this function. (btw: it is a function and it takes an argument ofc)

see here

if (!ctype_alpha($first))...

I can see that I have some problems to have the ctype_alpha accept the danish special charaters like: æ, ø, å.

Do you have some solutions for that also?

Thanks

You can set the locale using [man]setlocale/man.
