You don't enter the word null into value box. Create html page with multiple checkboxes. Create table `user` ( `userid` int (11) not null auto_increment, `firstname` varchar (30) not null, `lastname` varchar (30) not null, `address.

The field in the database is currently set to tinyint but i would be happy to change for something that works. Make sure you set them to null not 'null', as the one with quotes is recognised as a string value. 5) click the ‘null” checkbox.

Click databases, create a database and name it as “sample”. First, we're going to create a database that contains our data. I mean getting the checkbox values from a database and puting it on form instead or hardcoding it.
