I think this is more of an HTML question, but I am also using PHP, so I decided to put it in the blog title.
If I wanted to create a form connected to a database and wanted to display the contents of a drop down field, I would use something like:
< option selected="selected" value="< ?php echo $script_architecture ?>" >< ?php echo $script_architecture ? >
How would I do the same with a checkbox?
