# Emoji One

bringing you emojione.com & emoji.codes

The web's first and only complete open source emoji set. It is 100% free and super easy to integrate.

The Idea

To standardize emoji on the web through the use of common :shortnames:.

When storing user inputted text in your database, say from a guestbook or through a CMS admin, you should always make sure you are storing text containing only :shortnames: and not Unicode emoji characters or emoji images. Then, when you are displaying that content to the user, you can convert it server-side with the PHP toolkit provided, or client-side using the Javascript toolkit which is also provided. Demos of this process using Javascript, jQuery, and PHP are included in the repo, and we have example code snippets below.

What are Shortnames?

Shortnames are semi-standardized human-readable identifiers for each emoji icon. Many online web applications will accept these shortnames as alternatives for the actual unicode character. We've compiled the full list over at emoji.codes with quick copy & search functions.

Installation

We've teamed up with JSDelivr to provide a simple way to install these emoji on any javascript-enabled website. Add the following script and stylesheet links to the head of your webpage:

<script src="//cdn.jsdelivr.net/emojione/1.3.0/lib/js/emojione.min.js"></script>
<link rel="stylesheet" href="//cdn.jsdelivr.net/emojione/1.3.0/assets/css/emojione.min.css"/>

Quick installs can also be done using NPM and Bower (for the Javascript toolkit) or Composer (for the PHP toolkit).

NPM

> npm install emojione

Bower

> bower install emojione

Composer

 "require": { "emojione/emojione": "dev-master" }

##Usage Examples

Below there are some examples of how you will actually use the libraries to convert Unicode emoji characters to :shortnames: and :shortnames: to emoji images.

###Javascript Conversion

.toShort(str) - native unicode -> shortnames

This demo shows you how to take native unicode emoji input, such as that from your mobile device, and translate it to their corresponding shortnames. (we recommend this for database storage)

.shortnameToImage(str) - shortname -> images

This demo shows you how to take input containing only shortnames and translate it directly to Emoji One images. (when displaying the unified input to clients)

.unicodeToImage(str) - native unicode -> images

This demo shows you how to take native unicode emoji input, such as that from your mobile device, and translate it directly to Emoji One images. (would be great for a live editor preview)

.toImage(str) - native unicode + shortnames -> images (mixed input)

This demo shows you how to take input containing both native unicode emoji and shortnames, and translate it into Emoji One images for display.

###PHP Conversion

::toShort($str) - native unicode -> shortnames

This demo shows you how to take native unicode emoji input, such as that from your mobile device, and translate it to their corresponding shortnames. (we recommend this for database storage)

::shortnameToImage($str) - shortname -> images

This demo shows you how to take input containing only shortnames and translate it directly to Emoji One images. (when displaying the unified input to clients)

::unicodeToImage($str) - native unicode -> images

This demo shows you how to take native unicode emoji input, such as that from your mobile device, and translate it directly to Emoji One images. (would be great for a live editor preview)

::toImage($str) - native unicode + shortnames -> images (mixed input)

This demo shows you how to take input containing both native unicode emoji and shortnames, and translate it into Emoji One images for display.

###Extras

Shortname Autocomplete

Easily add shortname autocomplete functionality to any text input on your page.

ASCII Smiley Conversion

With one quick step you can start converting common ASCII smileys to their corresponding images.

Alternate Alt Tags

Change from the native unicode emoji in the resulting alt tags to their shortnames insteads.

Live Preview Box

Display converted Emoji in a preview box as the user is typing.

Conversion HTML Class

Stick a class of .emojione-convert on any HTML element and automatically convert native unicode emoji and/or shortnames to images after page load.

Convert on Form Submission

Converts unicode input to shortnames once the user submits the form.

Sprites (PNG)

With an additional CSS file you can use Emoji One as resizeable PNG sprites (up to 64x64).

Sprites (SVG)

This sprite method requires no extra CSS, and is infinitely resizeable.

Other Considerations

###Character Encoding — UTF-8

If you're getting serious about implementing emoji into your website, you will want to consider your web stack's character encoding. You should make sure that all connection points are using the same encoding. There are a lot of options and configuration possibilies here, so you'll have to figure what works best for your own situation.

A quick Google search will bring up a lot of information on how to get your entire web stack to use UTF-8, which is needed to properly handle Unicode emoji.

To get you started, here's a nice guide: UTF-8: The Secret of Character Encoding.
