Insert content into <title> head tag with function

Question

Is there a hook available that lets you append or prepend text to the <title> tag in the head?

I've seen lots of posts about customizing the <title> tag, but they all involve manually adding a function inside the <title> tag. I'm looking to modify it with a hook if possible so it can be easily turned on/off in a functions.php file.

Answer 1

The content is modified with filters, not hooks.

To modify the <title>, use wp_title filter

Example:

  add_filter('wp_title', 'set_page_title');

  function set_page_title($orig_title) { 
    return 'Modified ' . $orig_title;
  }

Answer 2

yes, it's wp_title
