There is a very poor coding practice among freelancers that they create individual pages for every custom post types, but I think there is a better way to do this by Creating functions in
functions.php and then calling those functions.
For any Function/meta created in
functions.php, how to integrate or call that function for Custom Post types?
I am unable to Understand the basic logic can come one explain.
EDIT from comments
....my question was suppose there is a meta created for BIG text (Through Function)and now we have 10 custom post types and we want this meta to be shown in 5 CPT's then w/o repeating the codes how can we build function and attach it to those custom post types?
