Downloads webfonts (like for example Google-Fonts), and hosts them locally on a WordPress site.
This improves performance (fewer requests to multiple top-level domains) and increases privacy. Since fonts get hosted locally on the site, there are no pings to a 3rd-party server to get the webfonts and therefore no tracking.
A WordPress theme will typically enqueue assets using the wp_enqueue_style function:
function my_theme_enqueue_assets() {
// Load the theme stylesheet.
wp_enqueue_style(
'my-theme',
get_stylesheet_directory_uri() . '/style.css',
array(),
'1.0'
);
// Load the webfont.
wp_enqueue_style(
'literata',
'https://fonts.googleapis.com/css2?family=Literata&display=swap',
array(),
'1.0'
);
}
add_action( 'wp_enqueue_scripts', 'my_theme_enqueue_assets' );To locally host the webfonts, you will first need to download the wptt-webfont-loader.php file from this repository and copy it in your theme. Once you do that, the above code can be converted to this:
function my_theme_enqueue_assets() {
// Include the file.
require_once get_theme_file_path( 'inc/wptt-webfont-loader.php' );
// Load the theme stylesheet.
wp_enqueue_style(
'my-theme',
get_stylesheet_directory_uri() . '/style.css',
array(),
'1.0'
);
// Load the webfont.
wp_enqueue_style(
'literata',
wptt_get_webfont_url( 'https://fonts.googleapis.com/css2?family=Literata&display=swap' ),
array(),
'1.0'
);
}
add_action( 'wp_enqueue_scripts', 'my_theme_enqueue_assets' );$remote_url = 'https://fonts.googleapis.com/css2?family=Literata&display=swap';
$contents = wptt_get_webfont_styles( $remote_url );
Returns the stylesheet contents, using locally hosted webfonts.
$remote_url = 'https://fonts.googleapis.com/css2?family=Literata&display=swap';
$contents = wptt_get_webfont_url( $remote_url );
Returns a stylesheet URL, locally-hosted.
The wptt_get_webfont_url will - by default - download .woff2 files. However, if you need to support IE you will need to use .woff files instead. To do that, you can pass woff as the 2nd argument in the wptt_get_webfont_url function:
wptt_get_webfont_url( 'https://fonts.googleapis.com/css2?family=Literata&display=swap', 'woff' );If you have the need to store font files in a custom directory you can pass a custom path and URL using filters. Be sure you add these filters BEFORE the file containing the WPTT_WebFont_Loader class is called.
/**
* Change the base path.
* This is by default WP_CONTENT_DIR.
*
* NOTE: Do not include trailing slash.
*/
add_filter( 'wptt_get_local_fonts_base_path', function( $path ) {
return WP_CONTENT_DIR;
} );
/**
* Change the base URL.
* This is by default the content_url().
*
* NOTE: Do not include trailing slash.
*/
add_filter( 'wptt_get_local_fonts_base_url', function( $url ) {
return content_url();
} );
/**
* Change the subfolder name.
* This is by default "fonts".
*
* Return empty string or false to not use a subfolder.
*/
add_filter( 'wptt_get_local_fonts_subfolder_name', function( $subfolder_name ) {
return 'fonts';
} );
