Document title in 4.4

WordPress 4.1 introduced a way for themes to support a new way of rendering the document title, letting CoreCore Core is the set of software required to run WordPress. The Core Development Team builds WordPress. handle its generation and output. The next step followed just recently (#31078), deprecating wp_title() and replacing it with a more comprehensive way to generate titles.

UPDATE 12 November – wp_title has been reinstated until alternative usages have been identified and a path forward for them defined.

PluginPlugin A plugin is a piece of software containing a group of functions that can be added to a WordPress website. They can extend functionality or add new features to your WordPress websites. WordPress plugins are written in the PHP programming language and integrate seamlessly with WordPress. These can be free in the WordPress.org Plugin Directory https://wordpress.org/plugins/ or can be cost-based plugin from a third-party authors can now check for theme support and have a few new filters available that will allow them to change or replace the title in a reliable way:

  • 'pre_get_document_title' short-circuits wp_get_document_title() if it returns anything other than an empty value.
  • 'document_title_separator' filters the separator between title parts.
  • 'document_title_parts' filters the parts that makemake A collection of P2 blogs at make.wordpress.org, which are the home to a number of contributor groups, including core development (make/core, formerly "wpdevel"), the UI working group (make/ui), translators (make/polyglots), the theme reviewers (make/themes), resources for plugin authors (make/plugins), and the accessibility working group (make/accessibility). up the document title, passed in an associative array.

This latest change makes the new APIAPI An API or Application Programming Interface is a software intermediary that allows programs to interact with each other and share data in limited, clearly defined ways. (almost) feature complete and theme authors are discouraged from using wp_title() in the future. If it was decided to add a UIUI User interface to let users choose the make up of their document title, or another improvement to how title generation works, we now have a forward compatible way to handle these things.

To upgrade themes from using wp_title() to declaring theme support for core’s title-tagtag A directory in Subversion. WordPress uses tags to store a single snapshot of a version (3.6, 3.6.1, etc.), the common convention of tags in version control systems. (Not to be confused with post tags.) without breaking backwards compatibility with WordPress 4.0 and older, theme authors can check if the callback function exists and add a shiv in case it does not:

if ( ! function_exists( '_wp_render_title_tag' ) ) :
	function theme_slug_render_title() {
?>
<title><?php wp_title( '-', true, 'right' ); ?></title>
<?php
	}
	add_action( 'wp_head', 'theme_slug_render_title' );
endif;
