I'm currently in the process of building a wordpress multi-site for a client. I've completed aspect #1, which was creating Theme-1. Theme-1 was built utilizing excessive amounts of the AdvancedCustomFields PLUGIN.
I'm working to build Theme-2, this one is the primary theme that will be utilized for all of the sub-sites created through the multi-site option. The issue I'm having is that the AdvancedCustomFields are no longer an option, I need to build all of the customization into the functions.php file directly.
Is it possible to create custom fields through the theme directly - without utilizing a plugin?
I need the theme pages to have "Left Side" "Right Side" "Footer" as WYSIWYG editors. So if someone goes to create a new page all of these field settings are there by default.
Is this possible?
