Execute controller from view

[eluser]gtech[/eluser]
If you are displaying static HTML you should work out all the data you want display in the controller (by calling multiple models) and then build up a list of variables to parse in the view. you can call other controllers (or the same controller with different params) by providing a link in a href or form for the user to click on.

If you are building dynamic pages that use javascript and need to update/retrieve data without calling a new URL (drag and drop might be an example) then I have used ajax succesfully with the js file being loaded in a view.

home.js

Code:

$.ajax({
    async: false,               // wait for return
    data: '',                   // no data to pass
    dataType: 'json',
    success: home.loadComplete, // function to call on return
    type: 'POST',
    url: site + "/code/ajaxGetPrefs/" // the php controller to call
  });
  ....
  loadComplete: function(json_data)
  {
    ...
