I have modified twentythirteen template adding custom settings for my theme. All settings appear in theme customization section and I am able to save them.
I am using WP 3.6.
How to retrieve those custom settings in my theme file?
By default the settings of Twenty Thirteen are saved in DB in the
wp_options table, with the option_name
theme_mods_twentythirteen. You can get them with:
Also you must know that from version 3.4 WordPress uses a Customize Manager.
