You are right. A couple of fixes/suggestions, though. You should use absint as a sanitization callback. Also, you don’t have to explicitly use the WP_Customize_Control class. The number field can be created with the regular syntax you use for the text field with an exception of the type and additional attributes. Another thing is that … Read more

That’s indeed an interesting question. Looking at the following issues – both closed as won’t fix – I’d reason that replacing this color slider with a color picker is not recommended: https://github.com/WordPress/twentynineteen/issues/613 https://core.trac.wordpress.org/ticket/45619 Thing is, that Twenty Nineteen calculates the colors that will be displayed in the frontend from hue, saturation and lightness (HSL).

Use default values when you fetch the settings. Never store defaults in the database. Example: $defaults = array ( ‘foo’ => ‘bar’ ); $options = get_option( ‘my_theme_options’, $defaults ); echo $options[‘foo’];

The customizer preview is in a different window than the window that contains the customizer controls. Specifically, the customizer preview is contained inside of an iframe. So that is why you cannot directly use jQuery to select elements. One way to work around this is to use parent.jQuery from the preview, but this is not … Read more
Apparently custom nav menu walkers are not supported though they were supposed to be. I’m surprised this only has been discovered now. However, there is an easy fix for you to get them to work. Just add this to your theme: add_filter( ‘wp_nav_menu_args’, function( $args ) { if ( isset( $args[‘walker’] ) && is_string( $args[‘walker’] … Read more

So you could try: add_action( ‘wp_head’, ‘wpse_default_site_icon’, 99 ); add_action( ‘login_head’, ‘wpse_default_site_icon’, 99 ); function wpse_default_site_icon() { if( ! has_site_icon() && ! is_customize_preview() ) { // your default icons here } } The case when the site icon … Read more
tl;dr See standalone example plugin that demonstrates initiating a full refresh when a selective refresh request enqueues different scripts or styles and also which re-initializes JS behaviors for selectively-refreshed partial placement containers. I understand the goal to be to minimize the amount of logic required in the customizer to preview changes to updated partials that … Read more
You can get the list of widgets in a sidebar via: wp.customize(‘sidebars_widgets[sidebar-1]’).get() This is a list of the widgets’ IDs. The sidebars_widgets[sidebar-1] is the setting ID for the sidebar. Replace sidebar-1 with the ID of your sidebar. So to get the count just do: wp.customize(‘sidebars_widgets[sidebar-1]’).get().length If you want to listen for when a widget is … Read more
