php verification for calls to a database

php verification for calls to a database

I have set up a page on a site for collecting member information. I simply
want to key off a check box that needs to have a verification on it fail
if not checked. Also if any required field is NOT filled out. I am NOT
checking emails. I have the following $_POST['FirstName'],",".
$_Post['LastName'],",". and so on for the fields in code for the db. On
the html side (php set up)
