Action introduction before button to save customizer settings data.

[Collizo4sky]

In a project I am working on, we need to add an icon indication before the "Save & Publish" customizer button.

This patch introduces an Action before the button.

Can you please commit this @westonruter 🙏

@Collizo4sky hi, for this you'll want to use JavaScript to add the desired element to the Customizer. You may refer to the Customize Snapshots plugin for an ​example. You can see that this addButtons function gets called in a wp.customize.bind( 'ready, ... ) event callback.

But there is no harm in adding an action there. What can possibly go wrong?

[westonruter]

Actions and filters should only be added where required, when there is no alternative solution or established practice in place. Otherwise, it just adds bloat to WordPress.

@westonruter Not everyone is that great with JavaScript. Adding an action will make our life easier compared to going the javascript route. WordPress has lot's of actions and filters already, I don't see adding just one more reducing the bloat-ness of WordPress.

Kindly please reconsider your stance on this. I am sure a lot of persons who need to add something before the button will prefer this over the JS solution you linked to above.

@Collizo4sky Here is a simple standalone example for what you can do without adding a new action:

<?php
add_action( 'customize_controls_print_footer_scripts', function() {
        ?>
        <script>
                jQuery( function( $ ) {
                        $( '#customize-header-actions' ).prepend( $( '<span>Hello!</span>' ) );
                } );
        </script>
        <?php
} );

Thanks for the code snippet.
