Validation of text only field

[Anon]

I was trying to validate the input for a field that's supposed to be only alphabetic, no numbers.

Can anyone help?

Thanks.

i think there is an easier way, but this is what I am using until I figure out a better way:

<?php

$test = eregi_replace("([a-z])", "", $input);
if ($test != "") {
echo("Illegal username");
}

?>

if you want more than just letters, put what you want in the brackets and it will allow that symbol.

Thanks, that worked just fine.

You can can also use ereg instead of eregi and use (a-zA-Z) for the regex string, not that much difference but typically this will process faster.
