Wordpress replacing bloginfo with home_url?

Question

In my header file, I'm using Wordpress function bloginfo following three times:

<link rel="pingback" href="<?php bloginfo( 'pingback_url' ); ?>" />
<meta charset="<?php bloginfo( 'charset' ); ?>" />
<link rel="stylesheet" type="text/css" media="all" href="<?php bloginfo( 'stylesheet_url' ); ?>" />

But the theme check plugin gives me following warning:

bloginfo(url) was found in the file header.php. Use echo home_url() instead.

Can someone tell me how can I replace the that? I couldn't find any information in the function references on Wordpress website.

Answer 1

It may be not in your header.php .

find on all your active theme files any reference to:

bloginfo('url');

and replace it with:

echo home_url();
