insert multiple checkbox into database in php

hi
in my registration page i got about 20 input fields everythings are working fine except this multiple checkboxes. i read the articles related to my isses but no joy yet becouse my code is very complecated for example the register.php datas will be validate and process by process.php and then send to session.php from here data will be adding through database.php, so its very complecated where to add what for that i will give all the page code that related to register.php

the database field name is genaration tinyint(1),once i select one or two options and register it shows 0 value in genaration filed

here is the register.php
