Then strip the url from the conditions before redirecting. Aside from condtions you can also … Read more
Change directory where get_header(), get_footer() and get_sidebar() look for templates
Simple solution, use get_template_part(). For example: get_template_part( ‘partials/footer’ ); Which would get the footer.php inside the partials/ directory. Another example: get_template_part( ‘partials/footer’, ‘home’ ); Which would get the footer-home.php inside the partials/ directory. One more example: get_template_part( ‘partials/footer/blog’ ); Which would get the blog.php inside the partials/footer/ directory.

HTTP Security Headers in wp-config
The .htaccess file is read by the Apache server software before it even hands over to WordPress to generate a page. It is by far the best place to have your security headers. That said, WordPress does have a class to modify the headers before they are send to the browser. This class contains a … Read more
Headers already sent – WordPress core
WordPress provides a way to prevent the header HTML from being rendered, by appending &noheader=true to the url. That will cause the header HTML to wait for you to call it manually, so that you can do a redirect before that. To later render the header HTML from your page, you’ll have to use this: … Read more
Indenting (tabbing) WP_head
Technically possibly, but probably not worth the effort (and overhead). If you inspect the source with something like Developer Tools in Chrome, your HTML will be automatically indented. In fact, some caching plugins (like W3 Total Cache) even remove all whitespace to improve page load times. That said, if you want to ensure that your … Read more
