Code Snippet: Integrate Custom Fonts into Gutenberg, Bricks, Oxygen

Introduction
Builders Bricks and Oxygen allow the use of Google fonts.
It is also possible to integrate your own fonts, either directly or using additional plugins.
Legal Restrictions for Google Fonts
In some countries, the direct integration of Google fonts is problematic due to data protection regulations (GDPR, DSGVO, …).
Instead, Google fonts must be stored on your own server.
Cumbersome Integration of Custom Fonts
Most existing solutions for integrating your own fonts require you to upload the individual font files with the respective font family, style and weight. Depending on the number and variants of the font files, this is a time-consuming and cumbersome process.
Solution
This snippet simplifies the provision and integration of your own fonts:
The font files can simply be uploaded to a folder on your own server. The snippet automatically recognizes the font family, style and weight based on the file names. Fonts with variable weights are also supported.
I have developed the Web Font Loader for the integration of locally provided Google fonts:
Using this service, Google fonts can be easily downloaded in modern formats and uploaded to the folder on your own server.
The snippet recognizes these fonts and integrates them automatically, including support for variable font weights and Unicode ranges, if available.
Since version 3.4.0 of the snippet, the fonts are also available in the Gutenberg Editor.
Oxygen Builder allows you to select standard web-safe font combinations, Google Fonts and even TypeKit fonts.
Custom fonts, such as fonts licensed by the customer, are not available here.
Bricks Builder allows you to select web-safe default font combinations and Google Fonts. Besides, Bricks offers its own management for custom fonts. However, these fonts must be uploaded as individual files and manually registered with name, weight, and style.
Of course you can upload your own fonts to the server and then embed them by CSS yourself. But in Oxygen or Bricks such a font is still not available for selection.
Instructions
- Install the snippet.
You can either download the JSON file and import it into the plugins Code Snippets or Advanced Scripts,
or copy the source code and create a snippet yourself in your preferred snippet plugin. - Call any page of your website.
The snippet will automatically create a new directorywp-content/uploads/fonts
on your server. - Now you can add your own fonts and also locally stored Google Fonts.
Just follow the corresponding instructions below.
Google currently offers well over 1,000 fonts via its Google Fonts service, which can be used free of charge in accordance with the licenses of the respective creators.
The fonts can be integrated into your own website – but only via a direct connection to the Google servers. This is not easily permitted in some countries for data protection reasons (DSGVO, GDPR, …). For download, Google offers the fonts only in TTF format, which is not suitable for use on the web due to the file size.
Therefore, I have developed a web service Web Font Loader, which allows downloading Google fonts in modern and web-ready formats WOFF2 and WOFF.

Just choose the fonts you want to use and click the download button.
You will receive a ZIP file. Unzip this ZIP file. You will see a folder with the name of the font:

Upload the entire folder to the wp-content/uploads/fonts
directory on your server.
The folder contains important files that the snippet needs to properly integrate and deploy the fonts.
The snippet will automatically detect all available font files, weights, styles and also the available charsets. The necessary information is read from the included JSON file.
New as of version 3.2.6:
Since 2016, all major browsers support the WOFF2 font format.
A new option in the snippet prevents the old WOFF format from being offered to the browser.
This avoids that the browser unintentionally loads the WOFF files in addition to the WOFF2 files when using emoji or symbols on the page.
If older browsers, such as Internet Explorer or very old generation Apple devices, must be supported, this option can be changed in the configuration section of the snippet:
public static $wfl_support_woff = true; // Support old style WOFF files from Web Font Loader for browsers before 2016.
This option only affects fonts downloaded from the Web Font Loader.
Fonts from other sources will still be provided in all available formats.
Upload your font files to the wp-content/uploads/fonts
directory on your server.
Preferably the files should have modern formats like WOFF2 and WOFF.
However, older and proprietary ones like EOT and SVG are also supported, as well as formats that are not actually intended for use on the web, like OTF and TTF.
You can also organize the files in subfolders, e.g. grouped by font family.
The code snippet will find all font files, makes them available for selection in the builder and automatically generates the corresponding CSS code.
Font Files, Names, Weights and Styles
These details are determined from the file names.
The snippet supports the font formats EOT, OTF, SVG, TTF, WOFF, WOFF2.
The filename of the font file will be used as font name.
So for the font file "Matthias Altmann.woff2" the builder will display the font name "Matthias Altmann".
If the file name contains keywords for font weights, these are recognized and not included in the font name, but noted in the generated CSS code accordingly.
The following weights and styles are currently recognized:
Font Weight | Keywords |
---|---|
100 | Thin |
200 | ExtraLight, UltraLight |
300 | Light |
400 | Normal, Regular, Book |
500 | Medium |
600 | Demi, DemiBold, SemiBold |
700 | Bold |
800 | ExtraBold, UltraBold |
900 | Black, Heavy |
The keywords are not case sensitive and may contain hyphens between the keyword parts.ExtraLight
is therefore recognized in the same way as extra-light
.
Numeric values (100, 200, ...) in the file names are also recognized as font weights.
Furthermore, the keywords "italic" and "oblique" are recognized for the italic font style. Also here, the capitalization and a leading hyphen are irrelevant.
If there are multiple font files with the same name but different font formats (eot, otf, svg, ttf, woff, woff2), the builder will display the font name only once. However, the generated CSS will contain all available font formats. The browser will choose the preferred one by itself.
Fonts with variable weights are also supported: If the keywords VariableFont_wght
or [wght]
(case-insensitive) are recognized in the file name, the CSS is automatically adjusted for fonts with variable weights.
Configuration
There are some variables for configuration in the snippet.
The variables are listed and described in the source code in the CONFIGURATION section.
Testing the fonts
The snippet implements a test function that outputs a list of all fonts, weights and styles recognized and registered by the snippet. Here you can check the integration and display of the fonts, also in different font sizes.
Test with Admin Function
In the WordPress administration there is a new menu item "MA Custom Fonts" under Appearance
Here you get a quick overview of the fonts registered by the snippet

Test by Shortcode
The snippet provides a shortcode [ma-customfonts-test
].
This shortcode can be easily entered on a new page in the Gutenberg Editor. With the shortcode placed on a page you can easily test the fonts e.g. on a smartphone.

Performance
While developing the script I paid a lot of attention to efficiency and performance. Detecting existing fonts and generating the CSS code takes only milliseconds on an average server.
The CSS code for the fonts is linked as CSS file or emitted at the end of each page, no matter if one of the fonts is used on that page or not.
However, the browser loads a font only when it is really needed, and then only in the one preferred format.
Compatibility
Oxygen
So far, I know of some WordPress plugins that integrate custom fonts into Oxygen in a similar way: "Elegant Custom Fonts", "Oxy Font Manager", "Swiss Knife", "Use Any Font".
Since the way of implementation or the technical approach to integrate fonts into Oxygen are similar in these plugins and my code snippet, these solutions are not compatible. You have to choose one of these solutions. So please deactivate these plugins, or in case of "Swiss Knife", deactivate the "Font Manager" before using my Code Snippet.
Oxygen offers the possibility to embed Google Fonts directly.
If you want to use this code snippet to host Google Fonts locally on your own server, I recommend disabling Google Fonts support in Oxygen: Oxygen > Settings > Bloat Eliminator > Disable Google Fonts
Bricks
I am not aware of any incompatibilities with Bricks.
Bricks offers the possibility to embed Google Fonts directly.
If you want to use this code snippet to host Google Fonts locally on your own server, I recommend disabling Google Fonts support in Bricks: Bricks > Settings > Performance > Disable Google Fonts

Fixes: - Fixed PHP warning in admin_init(): Variable $builder_fonts_to_gutenberg definition was inside of Oxygen block, hence undefined in Bricks block. 2024-02-25 3.4.0 Reorganization of code base. New Features: - Support for assigning fonts in Gutenberg. Can be disabled by setting $gutenberg_font_family_select = false; - Oxygen Builder: Hide "Top 20" Google Fonts if Google Fonts are disabled. - Added filter for excluding ma-customfonts.css from FlyingPress CSS minimizer which causes issues with already minimized CSS containing @font-face rules. Changes: - Changed CSS file name from ma_customfonts.css to ma-customfonts.css - Changed test page slug from ma_customfonts to ma-customfonts - Removed setting $recursive for font file scan. Always scan recursive. - Added compatibility check for "Oxy Font Manager" - Oxygen Builder font lists now show "Custom" badge for injected fonts - Custom Fonts Test now loads CSS using URL parameter ver= to assure proper refresh. - Setting $fonts_in_gutenberg changed to $builder_fonts_in_gutenberg (Bricks, Oxygen) - Setting renamed: $cssoutput to $css_output, $cssminimize to $css_minimize, $fontdisplay to $font_display - $timing now allows levels 0/false (off), 1/true (basic), 2 (extended) - $timing now also calculates memory usage. Please note that memory usage won't simply be cummulated. Methods use memory temporarily but also free memory after use. 2022-10-17 3.3.1 Changes: - Migrated JavaScript from jQuery to vanilla JS (ES6) to eliminate jQuery dependency. - Modernized initialization to avoid errors with WPCodeBox: Replaced @ error control operator with ?? null coalescing operator (Thanks to Alexander van Aken for reporting) 2022-09-26 3.3.0 New Features: - Custom Fonts are now also available in Bricks Builder. They are listed in section "Standard Fonts". (Thanks to Luke Wakefield for the implementation idea and to Tom Homer for contacting and informing me about Luke's solution) - New configuration option $fonts_in_gutenberg: Allows to enable (default) or disable the assignment of custom fonts in Gutenberg. Changes: - Renamed code snippet from "MA Oxygen Custom Fonts" to "MA Custom Fonts" Fixes: - The snippet applies display and text fonts defined in Oxygen to Gutenberg Editor. Google fonts defined in Oxygen are not loaded for Gutenberg. So we can't assign Google fonts to Gutenberg. Only custom fonts are now assigned. (Thanks to Kamil Alhaijali for reporting) 2022-09-19 3.2.7 Compatibility Fix: - In Oxygen 4.0.4, Pro Menu calls ECF_Plugin::get_font_families() as Ajax call. For performance reasons, MA Custom Fonts doesn't get initialized for Ajax calls and doesn't have the base font directory set, which causes an error. We now just return an empty custom fonts list to prevent this error. That doesn't impact the Pro Menu functionality. (Many thanks to Kevin Pudlo from the Oxygen development team for reporting, support and testing concerning the Pro Menu component, and Alexander van Aken for reporting a similar issue concerning the Mega Menu component.) 2022-06-02 3.2.6 New Features: - New configuration option $wfl_support_woff: Font packages downloaded from Web Font Loader (https://webfontloader.altmann.de) contain WOFF2 files supported by all modern browsers, and also WOFF files to support ancient browsers before 2016 like Internet Explorer, or Safari on older Apple devices. The new default setting is to NOT provide old style WOFF files for ancient browsers. Set this option to true if you still need to support old browsers before 2016. (Many thanks to Sunny Trochaniak and Yan Kiara for reporting issues and supporting investigations with unexpected WOFF loading when using symbols/emoji) - Added display of timing details at end of page Appearance > MA Custom Fonts Fixes: - Corrected initialization of dummy ECF plugin to let Oxygen detect custom fonts and prevents attempts to be loaded as Google fonts (Thanks to Firat Sekerli for reporting) Changes: - Removed configuration and all code for debugging. - For Web Font Loader fonts: Only emit CSS if related font file exists. User might have deleted e.g. the files for a specific language. 2022-03-13 3.2.5 New Features: - Legend and coloring for font formats in custom fonts test screen Changes: - Renamed Admin menu Appearance > "Custom Fonts" to "MA Custom Fonts" - Renamed test shortcode from "maltmann_custom_fonts_test" to "ma-customfonts-test" - Optimized handling of font_base (dir, url) by class var - Enhanced detection of variable weight fonts by [wght] in filename (Thanks to Paul Batey for reporting) - Adapted min/max font weight for variable fonts from 100/900 to 1/1000 according to https://developer.mozilla.org/en-US/docs/Web/CSS/@font-face/font-weight#values (Thanks to Paul Batey for reporting) - Completely re-built custom font test screen (WP Admin and Shortcode) to improve - variable weight fonts (display logic) - responsive view (for test on smartsphones) 2022-02-11 Tested with PHP 8.0, WordPress 5.9, Oxygen 4.0 beta 1 2021-10-26 3.2.4 Changes: - Deferred initialization to hook wp_loaded, after incompatibility checks - Gutenberg: Apply custom fonts for new posts also - Renamed IDs (for scripts and styles) and CSS classes (for font test) for consistency Performance: - Avoid unneccessary init by separating admin/frontend and more detailed checks Fixes: - Fixed an issue comparing hashes for code and file (Thanks to David Sitniansky for reporting) - Emit styles for Gutenberg correctly if $cssoutput is configured as 'html' 2021-10-15 3.2.3 Changes: - Gutenberg: Use display font for post title (Thanks to Sunny Trochaniak for reporting) - Fonts preview: Changed sample text size from 15 to 16 px which is browser standard - Fonts preview: Shortcode output uses WP system fonts for UI instead of custom fonts - CSS file link now contains ?ver=... instead of ?hash only Performance: - Only create CSS file if contents (font configuration) have changed Fixes: - Removed itemprop="stylesheet" from <link rel="stylesheet" ...> (Thanks to Max Gottschalk for reporting and testing) - Proper quoting for font families 2021-08-02 3.2.2 Changes: - Using scheme-less URL to avoid issues with wrong WordPress URL configuration - Added admin notice if folder wp-content/uploads/fonts is not writable.
