wp_title

Definition:
function wp_title($sep = '»', $display = true, $seplocation = '') {}

Display or retrieve page title for all areas of blog.
By default, the page title will display the separator before the page title, so that the blog title will be before the page title. This is not good for title display, since the blog title shows up on most tabs and not what is important, which is the page that the user is looking at.

Parameters

  • string $sep: Optional, default is ‘»’. How to separate the various items within the page title.
  • bool $display: Optional, default is true. Whether to display or retrieve title.
  • string $seplocation: Optional. Direction to display title, ‘right’.

Return values

returns:String on retrieve, null when displaying.

Defined filters

  • wp_title
    apply_filters('wp_title', $title, $sep, $seplocation)
