Magento 2 Color Picker in system configuration

This tutorial is about addingColor Picker in Magento 2 admin configuration. In this article I will show how to add jquery color picker in Magento 2 system configuration. You can use following step to use this jquery color picker on frontend too. Magento 2 have default lib/web/jquery/colorpicker/js/colorpicker library so you don’t have to add any external library for that. Below are the steps of how to do it:

Lets start with the Image to demonstrate you what it looks like:

Magento 2 color picker

Magento 2 color picker

Here my Module Namespace is QaisarSatti.
And my module name is: HelloWorld

Lets have have a look at different steps below:

1. Create system.xml at app/code/QaisarSatti/HelloWorld/etc/adminhtml/system.xml
All admin config options for your module will go in this file. For color picker we will create a text field as below. Just for your information i have not added complete code here for sake of readability.

    <field id="color_background" translate="label" type="text" sortOrder="10" showInDefault="1" showInWebsite="1" showInStore="1">
         <label>Background Color</label>
         <frontend_model>QaisarSatti\HelloWorld\Block\ColorPicker</frontend_model> <!-- block for adding color picker on text box -->
     </field>

2. Create the QaisarSatti\HelloWorld\Block\ColorPicker.php
This code will enable color picker options with the text box.

<?php

namespace QaisarSatti\HelloWorld\Block;

class Color extends \Magento\Config\Block\System\Config\Form\Field {

   
    public function __construct(
    \Magento\Backend\Block\Template\Context $context, array $data = []
    ) {
        parent::__construct($context, $data);
    }

    protected function _getElementHtml(\Magento\Framework\Data\Form\Element\AbstractElement $element) {
        $html = $element->getElementHtml();
        $value = $element->getData('value');

        $html .= '<script type="text/javascript">
            require(["jquery","jquery/colorpicker/js/colorpicker"], function ($) {
                $(document).ready(function () {
                    var $currentelement = $("#'
. $element->getHtmlId() . '");
                    $currentelement.css("backgroundColor", "'
. $value .'");  //adding already selected value

                    // Attach the color picker
                    $currentelement.ColorPicker({
                        color: "'
. $value .'",
                        onChange: function (hsb, hex, rgb) {
                            $el.css("backgroundColor", "#" + hex).val("#" + hex);
                        }
                    });
                });
            });
            </script>'
;
        return $html;
    }

}

Now
3. Add the color picker JavaScript library.
Now finally we need to add color picker JavaScript library to admin config pages. Magento 2 by default is shipped with Color picker jQuery plugin. This plugin is present in lib/web/jquery/colorpicker/ folder.
Create the app/code/QaisarSatti/HelloWorld/view/adminhtml/layout/adminhtml_system_config_edit.xml. This layout file will be called on all admin configuration pages. We will add our color picker JavaScript and CSS to this layout.

<!-- File: app/code/QaisarSatti/HelloWorld/view/adminhtml/layout/adminhtml_system_config_edit.xml -->

<?xml version="1.0" encoding="UTF-8"?>
<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" layout="admin-2columns-left" xsi:noNamespaceSchemaLocation="../../../../../../../lib/internal/Magento/Framework/View/Layout/etc/page_configuration.xsd">
    <head>
        <css src="jquery/colorpicker/css/colorpicker.css"/>
    </head>
</page>

Now clear the cache and refresh the page. You will see the color picker enabled in config option.

That’s it from this tutorial. I strongly believe there is always room for improvement.So i am open for any suggestion and feed back. Please feel free to leave hat you are thinking in the comments section below. Cheers.
