Icons

Creating a Theme for Tiki? See https://themes.tiki.org/IconsQuestion

PHP

Try to avoid direct inclusion of any image tags in PHP including icons. See the Templates below:

Templates

There is a Smarty function which helps to insert icons in the code:
lib/smarty_tiki/function.icon.php

It will display a Tiki icon, using theme icons if they exist. The function supports modern icon fonts, CDN delivery, and caching for optimal performance.

Icon Parameters

The Question function supports these parameters:

  • name: name of icon from iconset (recommended over _id)
  • size: size of icon when using icon fonts (eg: "lg", "2x", "3x")
  • style: style variant supported by the iconset (eg: for Font Awesome: "regular", "solid", "light", "brands")
  • class: custom classes for the anchor element
  • iclass: custom classes for the icon itself
  • ititle: custom title attribute for the icon
  • istyle: custom style for the icon itself
  • href: URL for making the icon clickable
  • title: tooltip text (also used for menu text)
  • data-bs-toggle: Bootstrap 5 data attribute for components

Performance Features

The icon system includes:

  • Automatic caching of rendered icons
  • CDN support for icon fonts
  • Error handling with fallback icons
  • Optimized theme-specific icon loading


Tiki 14 - Icon sets

Why?

The goal of having icon sets is to
- make it easy to change icons in Tiki
- keep icon usage in smarty tpl files simple
- move icon customization out of the smarty tpl files
- more focus in having a centralized, future proof way of handling icons in Tiki

How icons work from Tiki14

- Tiki remains to have one central function to manage icons, which is the existing icon smarty_tiki function (/lib/smarty_tiki/function.icon.php)
- To include an icon in a smarty tpl file is use the icon smarty_tiki function in the tpl files like this:


- Icons are referenced by a descriptive name in tpl-s (eg: "save", "delete", etc). Icon naming in the tpl files is focusing on functionality (eg: save, edit, delete, etc).
- Icons are part of an icon set. Icon sets are defined using a multidimensional array in a php file that provide settings and definitions for the icon files.
- Tiki ships with a default icon set (themes/base_files/iconsets/default.php), which is the fallback for all other icon sets. This file should not be modified for local customizations. The default iconset uses font-awesome fonts.

- Cascading iconset approach (similar to css): there is a base (default) icon set, other icon sets need to define only what should be different than the default icon set
- File name convention for icon sets: nothing special, it just have to be distinct than the existing ones in the themes/base_files/iconsets/ folder
- In the Look&Feel administration you can choose from the icon sets shipped with Tiki.
- If you want to contribute an icon set to Tiki, put it to the themes/base_files/iconsets/ folder with a distinct name eg: mybelovediconset.php, famfam.php etc.

Specification

Copy to clipboard
return array( 'name' => tr('Default (Font-awesome)'), // Mandatory, will be displayed as Icon set option in the Look&Feel admin UI 'description' => tr('The default system icon set using Font-awesome fonts'), // TODO display as Icon set description in the Look&Feel admin UI 'tag' => 'span', // The default html tag for the icons in the icon set. 'prepend' => 'fa fa-', 'append' => ' fa-fw', 'icons' => array( /* This is the definition of an icon in the icon set if it's an "alias" to one of the default icons. * The key must be unique, it is the "name" parameter at the icon function, * so eg: {icon name="actions"} * will find 'save' in the array and apply the specified configuration */ 'actions' => array( 'id' => 'play-circle', // id to match the defaults defined below ), 'add' => array( 'id' => 'plus-circle', ), ); }

Samples

Glyphicons iconset

Copy to clipboard
function iconset_glyphicons() { return array( 'name' => tr('Glyphicons'), 'description' => tr('Glyphicon focused iconset, see http://getbootstrap.com/components/'), 'tag' => 'span', 'prepend' => 'glyphicon glyphicon-', 'append' => '', 'icons' => array( 'actions' => array( 'id' => 'play-circle', ), 'add' => array( 'id' => 'plus-sign', ), ), 'defaults' => array( 'adjust', 'align-center', ); }

Legacy iconset (mainly famfamfam icons)

Copy to clipboard
function iconset_legacy() { return array( 'name' => tr('Legacy (pre Tiki14) icons'), 'description' => tr('Legacy (pre Tiki14) icons, mainly using famfamfam images'), 'tag' => 'img', 'prepend' => 'img/icons/', 'append' => '.png', 'icons' => array( 'actions' => array( 'id' => 'application_form', ), 'add' => array( 'id' => 'large/icon-configuration', ), 'defaults' => '', ); }

Theme specific icon set

Customization


Params will be used as attributes for a HTML tag (e.g. class, etc.), except for special params starting with '_' :

  • - _id: short name (i.e. 'page_edit') or relative file path (i.e. 'img/icons/page_edit.png'). required
  • - _type: type of URL to use (e.g. 'absolute_uri', 'absolute_path'). Defaults to a relative URL.
  • - _tag: type of HTML tag to use (e.g. 'img', 'input_image'). Defaults to 'img' tag.
  • - _notag: if set to 'y', will only return the URL (which also handles theme icons).
  • - _menu_text: if set to 'y', will use the 'title' argument as text after the icon and place the whole content between div tags with a 'icon_menu' class (not compatible with '_notag' param set to 'y').
  • - _menu_icon: if set to 'n', will not show icon image when _menu_text is 'y'.
  • - _confirm: text to use in a popup requesting the user to confirm its action (yet only available with javascript)
  • - _defaultdir: directory to use when the _id param does not include the path
  • - _extension: Filename extension - default 'png'


When introducing new icon in .tpl file, developers should always use this icon Smarty syntax:

Copy to clipboard
{icon _id=error style="vertical-align: middle"}


The example above means it will create icon from the img/icons/error.png file and add a style attribute to it.

Tiki 13

There are glyphicons (font vector format icons) being introduced now in trunk with Bootstrap instead of bitmap (image based) icons.
For example you can have "OK" icon rendered by this HTML code:

Copy to clipboard
<span class="glyphicon glyphicon-ok"></span>


Icon Cache System

The icon system implements automatic caching to improve performance:


Example of how caching affects icon generation:

Copy to clipboard
// First request - generates and caches HTML {icon name="save" class="btn btn-primary"} // Subsequent identical requests - returns cached HTML {icon name="save" class="btn btn-primary"} // Different parameters - generates new cache entry {icon name="save" class="btn btn-secondary" size="lg"}
