How to add Bloginfo Shortcode?

The bloginfo() function in WordPress gives you access to lots of useful information about your site. See the complete list. To access all these values from inside Page/Post content itself, we can make a shortcode to return the values. Add this to your functions.php file in your theme:

function digwp_bloginfo_shortcode( $atts ) {
   extract(shortcode_atts(array(
       'key' => '',
   ), $atts));
   return get_bloginfo($key);
}
add_shortcode('bloginfo', 'digwp_bloginfo_shortcode');

Now you can output any of the values by calling that shortcode with “key”. For example, the name of your site:

[bloginfo key='name']

Or directly to images in your theme folder:

<img src="[bloginfo key='template_url']/images/logo.jpg" alt="[bloginfo key='name'] logo" />
