Create a theme options page with CMB2
How do you actually echo out the options in your template files? I know about echo get_post_meta($post->ID, '_cmb_so_and_so', true); but not about how to echo the actual options, a company logo, a colour selected, etc. I could not find this in the wiki? Thank you though, this theme options page works like a charm, like a charm I tell you.
@BernardMyburgh
from the wiki, use '' to echo the theme options.
repeatable is not working
Text field type default value not echo until I set a value and save it. Any solution?
The option page add's backslashes to single and double quotes every time you save, any way around this?
Where should I put this code?
When I used this example, I found that all my quotes are escaped with a backslash ' probably because magic_quotes kicks in here. The strange thing is, that I haven't seen this, when I use the custom fields in a custom post type, instead of an option page. (probably the same problem that RJdeJong posted here a few days ago).
My quick workaround for this was to define a custom sanitization for the textarea fields that I use in the option page and put a stripslashes() here.
If it's happening on save, custom sanitization callback may be needed. If only happening on display, you'll want a custom escaping callback.
Line 143 should be 'cmb2_get_option' in order for this to work with CMB2.
taxonomy_multicheck working but not in admin display - its always show all the checkboxes checked
Is there a hook to display a message when the metabox gets saved?
Is there a way to use this to create multiple options/sections? Basically I want to have "Social Links", "Homepage Layout", etc as sections that have their own custom fields..
Like any other Theme Options panels that come with themes these days.
Can repeatable groups work in here? I cant get it to...
@amitrahav taxonomy_multicheck is for setting terms on posts/users. It shouldn't be used for an admin page. @mauricenaef you can use the 'admin_notices' hook. @owldesign you can use the 'title' field type to highlight sections. @thatryan yes, should work the same.
Important to note: the key that makes CMB2 save the data is line 104: https://gist.github.com/jtsternberg/8601075#file-theme-options-cmb-php-L104
show_on must be an array and key must be set to "options-page". This was not obvious to me as I deconstructed this.

You are missing a bracket around line 110 to close the 'fields' array.
