Dear forum:
I'm trying to do several basic things with an HTML form and PHP. So far,
I've gotten the form to write to a MySQL database, send email and echo the
fields after the form is submitted.
Next I'd just like to confirm that the fields are not blank and send a
custom error message. But I think I'm confused about where to place the
code.
I've purchased four books on PHP and I've been working for four days and I'm
so stuck. Am I missing some online source for information? I've been to
PHP.net and have not found answers.
The two files below are the HTML and PHP files that are working. The third
file is one of my attempts to check for a blank field and write a custom
error message.
