More Information

Displays information about your site, mostly gathered from the information you supply in your User Profile and General Settings WordPress Administration Screens. It can be used anywhere within a template file. This always prints a result to the browser. If you need the values for use in PHP, use get_bloginfo().

Possible values for $show

• ‘name‘ – Displays the “Site Title” set in Settings > General. This data is retrieved from the “blogname” record in the wp_options table.
• ‘描述‘ – Displays the “Tagline” set in Settings > General. This data is retrieved from the “blog 描述” record in the wp_options table.
• ‘wpurl‘ – Displays the “WordPress address (URL)” set in Settings > General. This data is retrieved from the “siteurl” record in the wp_options table. Consider echoing 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‘ – Displays the “Site address (URL)” set in Settings > General. This data is retrieved from the “home” record in the wp_options table. Consider echoing home_url() instead.
• ‘admin_email‘ – Displays the “E-mail address” set in Settings > General. This data is retrieved from the “admin_email” record in the wp_options table.
• ‘charset‘ – Displays the “Encoding for pages and feeds” set in Settings > Reading. This data is retrieved from the “blog_charset” record in the wp_options table. Note: this parameter always echoes “UTF-8”, which is the default encoding of WordPress.
• ‘version‘ – Displays the WordPress Version you use. This data is retrieved from the $wp_version variable set in wp-includes/version.php.
• ‘html_type‘ – Displays 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‘ – Displays the Text Direction of WordPress HTML pages. Consider using is_rtl() instead.
• ‘language‘ – Displays the language of WordPress.
• ‘stylesheet_url‘ – Displays the primary CSS (usually style.css) file URL of the active theme. Consider echoing get_stylesheet_uri() instead.
• ‘stylesheet_directory‘ – Displays the stylesheet directory URL of the active theme. (Was a local path in earlier WordPress versions.) Consider echoing get_stylesheet_directory_uri() instead.
• ‘template_url‘ / ‘template_directory‘ – URL of the active theme’s directory. Within child themes, both get_bloginfo(‘template_url’) and get_template() will return the parent theme directory. Consider echoing get_template_directory_uri() instead (for the parent template directory) or get_stylesheet_directory_uri() (for the child template directory).
• ‘pingback_url‘ – Displays the Pingback XML-RPC file URL (xmlrpc.php).
• ‘atom_url‘ – Displays the Atom feed URL (/feed/atom).
• ‘rdf_url‘ – Displays the RDF/RSS 1.0 feed URL (/feed/rfd).
• ‘rss_url‘ – Displays the RSS 0.92 feed URL (/feed/rss).
• ‘rss2_url‘ – Displays the RSS 2.0 feed URL (/feed).
• ‘comments_atom_url‘ – Displays the comments Atom feed URL (/comments/feed).
• ‘comments_rss2_url‘ – Displays the comments RSS 2.0 feed URL (/comments/feed).
• ‘siteurl‘ – Deprecated since version 2.2. Echo home_url(), or use bloginfo(‘url’).
• ‘home‘ – Deprecated since version 2.2. Echo home_url(), or use bloginfo(‘url’).

   Show Blog Title

   Display your blog’s title in a tag.

   
   <h1><?php bloginfo( 'name' ); ?></h1>
   

Show Blog 描述

Displays the tagline of your blog as set in Settings > General.

<p><?php bloginfo('描述'); ?> </p>

If using bloginfo as a variable, for example:$url = bloginfo('url'); it will return null. This is because bloginfo() echos the result immediately. So if you want to use any of the bloginfo() parameters as variables use get_bloginfo(). This function returns the result as a string.

Example output

In this example case, the Site Address (URL) is shown as http://www.example.com/home, and the WordPress address (URL) is displayed as http://www.example.com/home/wp.

<?php } ?>
