[Vtigercrm-developers] VT6 Architecture: *_View class?

[Uma S]

Hi Alan,

Differences between, the preProcess() and process() functions?

In Ajax request preProcess() wont be executed. Only process will execute.
You can see in WebUI.php(includes/main) which is an entry-point file. In
this triggerPreProcess() api is checking if its ajax request, if it is
return, if not execute preprocess().

What is the purpose and use?

The preprocess() api is bascically used to get the static things rendered,
in our crm the top-menu bar is rendered through preprocess(). which remains
same in all views.

The process() api is used to response for user request, which keep changing
randomly. for example in list-view, contents of list-view will change based
on sorting,page-navigation, which is handled by process() api.
