get_bloginfo()

返回你博客的信息，这些信息可以用在任何地方的 PHP 代码中。这个函数，和 bloginfo() 一样，可以用来在模板文件的任何地方显示你博客的信息。

用法

 <?php $bloginfo = get_bloginfo( $show, $filter ); ?> 

参数

$show

(string) (可选) Keyword naming the information you want.

默认值: name

• ‘name’ – Returns the “Site Title” set in Settings > General. This data is retrieved from the “blogname” record in the wp_options table.
• ‘description’ – Returns the “Tagline” set in Settings > General. This data is retrieved from the “blogdescription” record in the wp_options table.
• ‘wpurl’ – Returns the “WordPress address (URL)” set in Settings > General. This data is retrieved from the “siteurl” record in the wp_options table. Consider using site_url() instead, especially for multi-site configurations using paths instead of subdomains (it will return the root site not the current sub-site).
• ‘url’ – Returns the “Site address (URL)” set in Settings > General. This data is retrieved from the “home” record in the wp_options table. Equivalent to home_url().
• ‘admin_email’ – Returns the “E-mail address” set in Settings > General. This data is retrieved from the “admin_email” record in the wp_options table.
• ‘charset’ – Returns the “Encoding for pages and feeds” set in Settings > Reading. This data is retrieved from the “blog_charset” record in the wp_options table.
• ‘version’ – Returns the WordPress Version you use. This data is retrieved from the $wp_version variable set in wp-includes/version.php.
• ‘html_type’ – Returns the Content-Type of WordPress HTML pages (default: “text/html”). This data is retrieved from the “html_type” record in the wp_options table. Themes and plugins can override the default value using the pre_option_html_type filter.
• ‘text_direction’ – Returns the Text Direction of WordPress HTML pages. Consider using is_rtl() instead.
• ‘language’ – Returns the language of WordPress.
• ‘stylesheet_url’ – Returns the primary CSS (usually style.css) file URL of the active theme. Consider using get_stylesheet_uri() instead.
• ‘stylesheet_directory’ – Returns the stylesheet directory URL of the active theme. (Was a local path in earlier WordPress versions.) Consider using get_stylesheet_directory_uri() instead.
• ‘template_url’ / ‘template_directory’ – URL of the active theme’s directory (‘template_directory’ was a local path before 2.6; see get_theme_root() and get_template() for hackish alternatives.) Within child themes, both get_bloginfo(‘template_url’) and get_template() will return the parent theme directory. Consider using get_template_directory_uri() instead (for the parent template directory) or get_stylesheet_directory_uri() (for the child template directory).
• ‘pingback_url’ – Returns the Pingback XML-RPC file URL (xmlrpc.php).
• ‘atom_url’ – Returns the Atom feed URL (/feed/atom).
• ‘rdf_url’ – Returns the RDF/RSS 1.0 feed URL (/feed/rfd).
• ‘rss_url’ – Returns the RSS 0.92 feed URL (/feed/rss).
• ‘rss2_url’ – Returns the RSS 2.0 feed URL (/feed).
• ‘comments_atom_url’ – Returns the comments Atom feed URL (/comments/feed).
• ‘comments_rss2_url’ – Returns the comments RSS 2.0 feed URL (/comments/feed).
• ‘siteurl’ – Deprecated since version 2.2. Use home_url(), or get_bloginfo(‘url’).
• ‘home’ – Deprecated since version 2.2. Use home_url(), or get_bloginfo(‘url’).

$filter

(string) (可选) Keyword specifying how to filter what is retrieved.

默认值: raw

• ‘display’ – Passes the value of $show through the wptexturize() function before returning it to caller.
• ‘raw’ – Returns the value of $show as is.
