ssp_single_export_additional_urls
The "ssp_single_export_additional_urls" hook allows you to manually include additional URLs to parse and export during static generation of your WordPress site. This can be helpful for example when you want to include a custom page or file that is not referenced on your page like a json or txt file.
add_filter('ssp_single_export_additional_urls', function( $urls ) { // URL to a file. $urls[] = 'https://your_site_url.com/example.txt'; return $urls; } );
