For example if someone is creating a search plugin, how will he call user info with avatar and for that matter any other info like videos, events etc.

I have a complete code for a search plugin with php, css and js files, but it was not built for oxwall. It has a .sql to create a table, but here in our oxi website, we already have a database and just have to fetch it and show to the user.

I guess it is simple, but I am not a dev so may be difficult for me. I want to try myself atleast. I want someone to provide code and also tell me where to put it. Attached file is a components file contains a code which i think might bring the data
