php - Joomla 3.x documenation Creating Input forms -

well taking hours search right stuff out joomla documentation , forums still not answer.i unable clean documentation developer. doc seems scattered here , there. here rescue.

a) there clean documentation/tutorial resource developer core api (a version specific great)

b) current issue not want use existing component , want to
create simple extension perform crud operation on table (add /edit/delete)

c) how create html forms /validate it, add/update/delete etc normal operation in web application. please point me resource specific 3.x

the documentation joomla 2.5 still relevant 3.1 forms. can compare other components such weblinks others have suggested.

http://docs.joomla.org/j2.5:developing_a_mvc_component/

as bare essentials need controllers (one list, 1 add/edit), models (list + add/edit), form xml add/edit, table list, view controller , view template.

the documentation linked explains how add them , descriptive. havn't noticed different between docs , current joomla 3 components.

the thing need watch out of classes need have name changed.

in particular views need jviewlegacy instead of jview.
