Hi,
I am using that right now and i have don't know how to include blank fields. For example if a user does not fill a field in a form i want to accept it. I tried the code you posted, for now it is blocking blank fields.
Thank you

What you tried only requires ONE a-z character somewhere in the input.
Try this:
preg_match('^[a-z]+$', $fname);
This will:
^ "anchor" the string at the beginning
[a-z]+ a to z, with at least one letter
$ "anchor" the string at the end
Note, however, that some people have other characters in their first
name, such as apostrophe, space, and dash.
Oh, and the digit 3, for "bo3b" who was a programmer on the first
Apple Macintosh. His parents were hippies, and that really is his
name...
You may want to obtain a LARGE list of "first names" and run them
through your validator as a test.
