I would like to add a meta value to the title
<title> tag in a custom post typed page. So there would be meta value before normal post title. I have a custom field created that contains the needed data, but I don't know how to show it in the
<title>. I can show it in pages
<h1> in a template file, but I need the title tag to start with that data.
How to do this? My theme uses
<?php wp_head(); ?> and
add_theme_support( 'title-tag' ); to print title.
