What should be the “sanitize_callback” for select? If I do not add “sanitize_callback” for select it will show this error message in Theme Check
REQUIRED: Found a Customizer setting that did not have a sanitization callback function. Every call to the add_setting() method needs to have a sanitization callback function passed.
or the reviewer will allow this?
I tried using this code
'sanitize_callback' => 'esc_url_raw',
but I think it is only for URL…
anyone can help me?
