Demo

Features

  • icon picker form element
  • icon field for tt_content, pages and sys_category
  • RTE plugin
  • icon gallery with filter function
  • displays icons from image files or font (css)
  • extracts and caches font styles (css)
  • works with remote css files
  • can include generated stylesheet in the frontend

Pro tip: Use your Icomoon development file. Your Icon Picker is always up to date, and you can serve the font files from your own remote without manually downloading and adjusting paths!

Installation

  1. Install via composer

    composer require blueways/bw-icons
    
  2. Update database schema

  3. Include PageTS

    Enable the extension in the Extension Manager and include the static PageTS for TYPO3 core icons or set up your own icons. See Configuration section.

  4. Enable icons for tt_content, pages and/or sys_category

    In the extension settings (Admin Tools → Extension Configuration → bw_icons), you can enable the icon fields. If you want to use it for other tables, see For developers section.

  5. Include RTE configuration (optional)

    imports:
       - { resource: EXT:bw_icons/Configuration/RTE/IconPicker.yaml }
    
    editor:
       config:
         toolbar:
           - { name: 'icon', items: [IconPicker] }
    

Configuration

The displayed icons are set up via PageTS. Choose a unique identifier and select FileIconProvider if you want to add image files from a directory or CssIconProvider if you want to display font icons from a stylesheet.

mod.tx_bwicons {

    # Get icons from directory and subdirectory. Subdirectories become sidebar links.
    typo3icons = Blueways\BwIcons\Provider\FileIconProvider
    typo3icons {
        title = TYPO3 Icons
        folder = EXT:core/Resources/Public/Icons/T3Icons/svgs
    }

    # Get icons from stylesheet. Multiple font-faces in one file become sidebar links.
    fontawesome = Blueways\BwIcons\Provider\CssIconProvider
    fontawesome {
        title = FontAwsome
        file = fileadmin/fontawesome/css/all.css
    }

    # Get icons from remote stylesheet. Styles and font files are cached in /typo3temp
    icomoon = Blueways\BwIcons\Provider\CssIconProvider
    icomoon {
        title = Icomoon
        file = https://i.icomoon.io/public/b23ec64zea/Project/style.css
    }
}

After changing the settings, make sure to clear the cache.

RTE Configuration

After importing the yaml configuration, you can add the new button anywhere you want to your RTE present. Read more about RTE configuration.

imports:
   - { resource: EXT:bw_icons/Configuration/RTE/IconPicker.yaml }

editor:
   config:
       toolbar:
           - { name: 'icon', items: [IconPicker] }

Usage

The icons are saved as filename ( e.g. EXT:myext/Resources/Public/Images/icon.svg or fileadmin/icons/foo.png) if you use the FileIconProvider or as css class names ( e.g. fas fa-arrow-right) by using CssIconProvider.

If you have configured only the selection of SVGs, you can safely use the <f:image src="{data.tx_bwicons_icon}" /> viewHelper in your fluid template.

By only using font icons, you can output like <i class="{data.tx_bwicons_icon}"></i>.

If you have a mixture, you can use my ViewHelper that determines the type by checking for a dot in the icon name:

{namespace bw=Blueways\BwIcons\ViewHelpers}

<bw:icon icon="{data.tx_bwicons_icon}"/> Hello world!

Output:

<i class="fa fas-wave"></i> Hello world!

or

<img src="/fileadmin/icons/foo.svg" /> Hello world!

CSS Frontend Include

If you want to include the extracted styles in the frontend, you can use the CssUtility to generate the style-tags in the head of your page. Include this in your TypoScript setup:

page.headerData {
	123 = USER
	123.userFunc = Blueways\BwIcons\Utility\CssUtility->includeStyleSheets
}

For developers

Usage in other tables

  1. Create database field for the icon:

    create table tx_myext_domain_model_foo (
        icon_field varchar(255) not null default '',
    );
  2. Edit TCA: Add the renderType iconSelection in the config array:

    ...
    'icon_field' => [
         'label' => 'My Icon',
         'config' => [
            'type' => 'input',
            'renderType' => 'iconSelection'
         ]
    ],
    ...

    Optional: you may restrict which icon providers are available:

    ...
    'icon_field' => [
         'label' => 'My Icon',
         'config' => [
            'type' => 'input',
            'renderType' => 'iconSelection',
            'iconProviders' => 'fontawesome,otherProviderKey'
         ]
    ],
    ...

New icon sources

If you want to add other icon sources (e.g. from API), you can create your own IconProvider. Just make sure to extend from Blueways\BwIcons\Provider\AbstractIconProvider.
