How create multi site setup in phalcon with some shared controllers , models, views with out duplicating views folder? - phalcon

Question

I need to setup multisite in phalcon where I need some common functionalities to be done among all sites and also will have site specific. Say it would have some common controllers modals and views, if I need anything to be changed in one particular site I should be able to change in that particular site with out affecting other sites. just by creating single view template and extending the controllers and modals. If i need to change anything in all sites then I could be able to change it in a single place.

Steps to setup multiple site with different domain name
Steps to acheive it
Step 1 : Register the namespaces of common controllers and models
Step 2 : Extend the phalcon view engine to cascading the view (say for example View engine will look for specific template file in site specific view folder if its not exist it will look in common views folder, there is no need to replicate all the template files in all sites views directories, you can overwrite single template file alone).
Step 3 : Extend Phalcon volt to provide Skin path for templates Step 4: Create site specific Volt cache folder
Step 5 : Create seperate folders with sitenames in public folder for js/css/images Step 6: Create common contollers, views, modals
Step 7: Extend common controllers , modals in site specific folderss , Views wil be taken from common folder. if you want to overwrite any template you can overwiite that alone no need all view folder. Step 8 : Set sitename by current domain name. this sitename will be used to register contollers models directries
Step 9: Set two views directory one is common and another is sitename (thi can be done only if you have extened the phalcon view to add two directories refer step 2) Files extended are here this should be in your public directory.
Files extended are here, this should be in your root directory.

To render Js and css site specific in volt tempaltes
You use can like this
{{ stylesheet_link(constant('SITENAME') ~'/css/main.css') }}
{{ javascript_include(constant('SITENAME') ~'/js/main.js') }}
