In wp-admin/customize.php you have Site Identity section that includes: Logo, Site Title, Tagline and Icon fields.
The site title and tagline I got working by creating the fields and adding this to functions.php
update_option('custom_logo', get_field('veebilehe_logo', 'options'), true);
update_option('blogname', get_field('veebilehe_pealkiri', 'options'), true);
update_option('blogdescription', get_field('luhikirjeldus', 'options'), true);
update_option('site_icon', get_field('veebisaidi_ikoon', 'options'), true);
But I have no idea how to get the Logo and Icon. I created image types for them but no idea what the Return Format should be or if it’s even correct.
Can anyone help?
Thanks.
