I have encountered the function get('state'), which , from documentation says something about 'model state variables'. Could someone please explain to me what 'model state variables' are?

Was looking for the same question and found an answer.

The state object is your storage for variables. If you dont store any there are none by default. If you look at com_banners/controller.php you see how it could be used.

Here is another reference:

doesn't this variable store information about published/unpublished items?

i.e. table `jos_banners` and `banner_clients` have column called "state", which, I think, is the newer version (in joomla 1.7) of joomla's 1.5 column `published`

no?

State variables are associated with functions like these, which are used in the model:

getState()
setState()
populateState()
getUserStateFromRequest()

They are often used to store information across multiple page views during the same session, like filter settings for viewing only certain records in a list (for example, to only view articles by a certain author in the Article Manager). When you come back to the list after leaving it, the filter settings are remembered.

If you're in a view, setting something equal to $this->get('State') will call the function getState() in the model. Setting something equal to $this->get('Marbles') in the view will call the function getMarbles() in the model.

The purpose of the 'state' column found in some database tables in Joomla 1.7 is a different concept. This is like the 'published' column in Joomla 1.5, with possible values like the following:

1 means published
0 means unpublished
2 means archived
-2 means trashed
