This plugin appears at Settings -> Fonts. For each @font-face, specify .woff URL, weight, style, and a font family name. Appropriate @font-face rules will be saved to a CSS file and enqueued with wp_enqueue_stylesheet, so that you can use the font with the font-family CSS property. No nonsense. No API keys. No font conversion. No bloat. Integration Instructions for Plugin & Theme Developers Use ECF_Plugin::get_font_families() to get a list of font families added with Elegant Custom Fonts. Then add these to any “Font” dropdowns in your plugin or theme. Example: if (class_exists(‘ECF_Plugin’)) { $font_family_list = ECF_Plugin::get_font_families(); } else { $font_family_list = null; } /* loop through the $font_family_list array and add each family to your ‘Font’ dropdowns */
