How do I group the following with [[:space:]] expression

[double]

I have a name field in which the first name is required but I also want to have it so that they can ass there last name (which would be optional) but I'm not sure how to group this properly so that when iI do have my last name there it will submit the form.

(!eregi("^{[a-z-]+[[:space:]]?([a-z-]?)$",} $name))

Thanks

I'm not exactly sure what you mean, but this is what I think.

If you want to check if the user has inputted their full name (First name and Surname) then,

$name = trim($name);
eregi(" ", $name);

will guarantee that if there's a space in there, there's text either side.

Hope this helps
