Dealing with non required forms in mysqli : <p>I am attempting to insert variables from a form into a mySQL database using a mysqli prepared statement. The problem I have run into is that one of my variables is not required and so when i don't enter anything for it in the form I get an error. 
How do I properly deal with this variable?
would i need to use a different prepared statement or could I keep the one I have? </p>
