Revision preview not showing changes

    When creating a revision (which is a draft) and doing some changes in it and then clicking on preview – the preview doesn’t show any changes (even though draft was saved). I figured it’s because it was using original post’s permalink and basically showing it instead of revision. I’ve come up with a fix which I’ll post below

    My fix is to change the permalink in revision by adding some unique slug to it and then removing that when publishing it back into original post:

    
// revisionize: revision draft preview not showing changes - fix

add_action( 'revisionize_after_create_revision', function( $original_id, $revision_id ) {
	// adding a unique slug to revision permalink that will be removed when publishing it back to original
	$add_slug = '-revisionize_some_slug';
	// updating post_name didn't work with revisionize to change permalink of revision. post_name was actually empty on revision post
	$permalink = get_post_meta( $revision_id, 'custom_permalink', true );
	if ( substr( $permalink, -1 ) === '/' ) {
		$permalink = substr( $permalink, 0, -1 ) . $add_slug . '/';
	} else {
		$permalink .= $add_slug;
	}
	update_post_meta( $revision_id, 'custom_permalink', $permalink );
}, 10, 2 );

add_action( 'revisionize_before_publish', function( $original_id, $revision_id ) {
	// removing our unique slug from permalink before publishing revision into original
	update_post_meta( $revision_id, 'custom_permalink', str_replace( '-revisionize_some_slug', '', get_post_meta( $revision_id, 'custom_permalink', true ) ) );
}, 10, 2 );
