[Vtigercrm-developers] Writing a function and using it in a custom module

[Asha]

Hi Darlington Mpofu,

Please see my comments inline:

> either


If the function is to perform action on client side, then you write it in
module.js. If the function is to perform action or do some computation on
the server side, then you write it in module.php. Some times you may have to
write function in module.js to trigger an action/function from module.php
file as a way to interact from client end.

You can call retrieve_entity_info on a CRMEntity instance to get the values
of all the fields and fetch them from the object. (You can also query them
directly from database if required).

Have a look at retrieve_entity_info function of data/CRMEntity.php file

It all depends on what your function does. If it performs a action that is
part of save, then it makes sense to have it in place.
