Description

Mudrava Icon Field for ACF with Lucide adds a new field type to Advanced Custom Fields (ACF) that allows users to select icons from the Lucide icon library and brand logos from Simple Icons through an intuitive visual picker. The selected icon value is stored in the database, making it lightweight and flexible for frontend rendering.

Requirements: This plugin requires Advanced Custom Fields (ACF) version 6.0 or higher to function.

  • Visual Icon Picker – Browse and select from 1,700+ Lucide icons and 3,400+ brand logos
  • Brand Icons – Brand logos use Simple Icons values such as simple:facebook
  • Smart Search – Filter icons by name or tags instantly
  • Performant – Local sprite file, inline frontend SVG output, paginated grid (100 icons per page)
  • Native ACF Look – Seamlessly integrates with ACF’s design language
  • Responsive – Works on all screen sizes
  • Accessible – Keyboard navigation support
  • Flexible Output – Return icon value or full SVG markup
  • No External Requests – All icon data is stored locally

Usage

After installing both ACF and this plugin:

  1. Go to Custom Fields > Add New
  2. Add a new field and select Lucide Icon as the field type
  3. Configure the field settings (default value, return format, etc.)
  4. Save your field group

Template Examples

Get Icon Name:

<?php
$icon_name = get_field('your_field_name');
echo esc_html($icon_name); // Returns: 'rocket'
?>

Get SVG Markup (with return_format = ‘svg’):

<?php
$icon_svg = get_field('your_field_name');
echo $icon_svg; // Returns: <svg>...</svg>
?>

Using the Helper Function:

<?php
// Basic usage
echo mudrava_get_lucide_icon('rocket');

// With custom attributes
echo mudrava_get_lucide_icon('rocket', [
    'class'  => 'my-custom-class',
    'width'  => 32,
    'height' => 32,
    'stroke' => '#ff0000',
]);
?>

About Lucide Icons

Lucide is a modern, open-source icon library with 1,700+ carefully crafted icons. The bundled Lucide assets are from lucide-static 1.14.0 and are licensed under ISC.

About Brand Icons

Brand logos are bundled separately from Simple Icons 16.18.0 and are saved with the simple: prefix, for example simple:facebook.

Simple Icons is distributed under CC0-1.0, but individual brand logos and trademarks may still be governed by each brand owner’s guidelines and permissions. Check the relevant brand guidelines before using a logo in production. Source and guideline URLs from Simple Icons are bundled in data/brand-icons-meta.json.

Privacy

Data Collection:

This plugin does not collect, store, or transmit any user data or personal information.

External Requests:

This plugin does not make any external HTTP requests. All icon data is stored locally and served from your WordPress installation.

Cookies:

This plugin does not use cookies.

Third-Party Services:

This plugin does not integrate with or send data to any third-party services.

Requirements

Before installing this plugin, ensure you have:

  • WordPress 6.0 or higher
  • PHP 7.4 or higher
  • Advanced Custom Fields (ACF) 6.0 or higher (required)

Installation Steps

  1. Install and activate ACF (if not already installed)
  2. Upload the mudrava-acf-lucide-field folder to /wp-content/plugins/
  3. Activate the plugin through the ‘Plugins’ menu in WordPress
  4. The new “Lucide Icon” field type will appear in ACF field type selection

Via WordPress Admin

  1. Go to Plugins > Add New > Upload Plugin
  2. Upload the plugin zip file
  3. Click Install Now and then Activate
Do I need ACF Pro for this plugin to work?

No. The field type works with Advanced Custom Fields 6.0 or higher. It also works inside ACF Pro field groups such as Repeaters and Flexible Content.

Will the plugin work if I deactivate ACF?

No, the plugin will show an admin notice and the field type will not be available. You must keep ACF active.

Does this plugin make external requests?

No. All icon data is stored locally in the plugin files. No external API calls or CDN requests are made.

Where are the icons stored?

Lucide SVG data is bundled in assets/sprite.svg. Brand logo SVG data is bundled in assets/brand-sprite.svg. Search metadata is stored in data/icons.json and data/brand-icons.json. Everything runs locally on your server.

Why did social or brand icons disappear after updating Lucide assets?

Lucide v1 removed most brand icons from the current packages. Version 1.1.0 updates Lucide to lucide-static 1.14.0 and adds a separate Simple Icons brand bundle, which is the recommended direction for brand logos. New brand values are saved as simple:<slug>, and legacy unprefixed social values such as facebook, instagram, twitter, or youtube are resolved against Simple Icons when they no longer exist in Lucide.

Can I use this with ACF Repeater or Flexible Content fields?

Yes, the Lucide Icon field works perfectly within Repeater fields, Flexible Content fields, and any other ACF field groups.

What format does the field return?

You can configure the return format in the field settings:
* Icon Name – Returns the icon value as a string (e.g., “rocket” or “simple:facebook”)
* SVG Markup – Returns the complete SVG HTML code

How do I customize the icon appearance?

Use the mudrava_get_lucide_icon() helper function with custom attributes for width, height, stroke color, fill color, and CSS classes.

Is the plugin translation-ready?

Yes, the plugin is fully translation-ready with text domain mudrava-acf-lucide-field. Translation files should be placed in the /languages/ directory.
