I am new to grocery crud as well as codeigniter. I am using following function for call_back but I is not working.
I am using 2 tabels
table_route(route_id(primarykey, autoincriment), fromcity_id, fromcity_name, tocity_id,tocity_name)
I am using set_relation for fromcity_id and tocity_id fields from table_route with city_id field in table_city
as with this set_relation I am only able to store city_id in in fromcity_id and tocity_id fields, I would also like to add city_name in fromcity_name and tocity_name fields. so I am using callback_after_insert and update functions to update citynames of the same table. my code as fallows.
even I am not able echo any text from call back function.
am I doing any mistake in above code?
