You'll have to use normal form submit buttons for this.
Javascript buttons that have functions responding to
onClick events can execute client-side code only, and can't
talk to your database.. a full-fledged submit must be done.
If you need 12 different buttons, you'll either need to
(as mentioned above) name the submit buttons, or use 12
different forms on your page. I would choose the latter of
those two choices, as it would let you break up the code
into more managable chunks, rather than one huge block of
code which must be re-parsed on every submit and use a bunch
of if/elsif statements. This also, of course, depends on
if, and how much, of the same code will be executed
depending on which button is pressed.
Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
