New issue 42 by moncojhr: Easy way to extend the class with new elements
http://code.google.com/p/php-form-builder-class/issues/detail?id=42

The issue by tom.berend "big picture.." , seems to be partly a request for
an easy way to extend the class, or a plug-in based system.

A user should not have to modify the class if there is not a specific type
of element already included.

I think we should only include the particularly standard element types in
the class, and then modularize the other elements.

They could be each a simple file that is loaded from the includes
directory, and then can be called through the form.

Sounds like a good idea. Some of the finer details may be a challenge to
integrate into class.form.php though.
How would js/php error checking work with the modularized form elements?
Which of the current elements
would be considered standard?

Perhaps all elements should be modularized, since there isn't really any
benefit to
having some of them hard-coded in the class.

There could be two different ways they could specify how the element will
be checked,
a simple way where they can just set a single regex or a more complex way
where they
could specify a function for checking the input.

The form class will then use that regex/function to decide it the input is
valid, and
then create then handle creating the js/php validation checking and error
message output.

I'm imagining there will be a folder in includes/ called "modules" and
inside
multiple files.. textbox.php captcha.php googlemap.php etc

Inside each will be a standardized structure, (element object?) , and it
will set a
few variables such as:

htmloutput
jsoutput
validation

and others that will be obvious when we actually implement it.

I think before we start to try and implement this we should create an
element with a
good structure, and afterwards actually convert the current elements to that
structure and make the form class handle it.
