You're not giving much information here.  What do you mean by "blank
field?"  That is to say: If the field (on the web form) is left blank,
what is your CGI script trying to do?

One way would be not try to set table fields to invalid values ;).

Look into using placeholders in your prepared statements and
conditionally binding them to NULL if a web form field has been left
blank by the user.
