Magento 2 Creating A UI Form

UI component is designed for Magento 2 software to render a User Interface (UI) in a simple and flexible way. To create a UI form in Magento 2 by using the UI component. For example that you want to create employee form as a UI form in admin, which has Employee Name, Employee Id, Employee Salary, and Employee Address field. The table name is supposed to be employee_details. First of all, you need to create a Model and Resource Model for this employee_details table.

Step 1: Create Router For Controller

In the first step, you need to create a routes.xml file in Magemeta/UiForm/view/adminhtml/layout folder.

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:App/etc/routes.xsd">
    <router id="admin">
        <route id="uiform" frontName="uiform">
            <module name="Magemeta_UiForm"/>
        </route>
    </router>
</config>

Step 2: Create A Controller

Please create a Edit.php file in Magemeta/UiForm/Controller/Adminhtml/Employee

<?php
namespace Magemeta\UiForm\Controller\Adminhtml\Employee;
 
use Magento\Framework\Controller\ResultFactory;
 
class Edit extends \Magento\Backend\App\Action
{
    /**
     * @return \Magento\Backend\Model\View\Result\Page
     */
    public function execute()
    {
        $resultPage = $this->resultFactory->create(ResultFactory::TYPE_PAGE);
        return $resultPage;
    }
}

Step 3: Create Layout File

In this step, we need to create uiform_employee_edit.xml layout file in ‘Magemeta/UiForm/view/adminhtml/layout’ folder.

<?xml version="1.0"?>
<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">
    <update handle="styles"/>
    <body>
        <referenceContainer name="content">
            <uiComponent name="employee_form"/>
        </referenceContainer>
    </body>
</page>

Step 4: Create employee_form.xml File In Magemeta/UiForm/view/adminhtml/ui_component

Now, we need to create employee_form.xml file in Magemeta/UiForm/view/adminhtml/ui_component

<?xml version="1.0" encoding="UTF-8"?>
<form xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Ui:etc/ui_configuration.xsd">
    <argument name="data" xsi:type="array">
        <item name="js_config" xsi:type="array">
            <item name="provider" xsi:type="string">employee_form.employee_form_data_source</item>
            <item name="deps" xsi:type="string">employee_form.employee_form_data_source</item>
        </item>
        <item name="label" xsi:type="string" translate="true">Employee Information</item>
        <item name="config" xsi:type="array">
            <item name="dataScope" xsi:type="string">data</item>
            <item name="namespace" xsi:type="string">employee_form</item>
        </item>

    </argument>
    <dataSource name="employee_form_data_source">

                <item name="collapsible" xsi:type="boolean">true</item>
                <item name="label" xsi:type="string" translate="true">Employee Details</item>
                <item name="sortOrder" xsi:type="number">20</item>
            </item>
        </argument>
        <field name="employee_id">
            <argument name="data" xsi:type="array">
                <item name="config" xsi:type="array">
                    <item name="dataType" xsi:type="string">text</item>
                    <item name="label" xsi:type="string" translate="true">Employee Id</item>
                    <item name="formElement" xsi:type="string">input</item>

                    <item name="dataScope" xsi:type="string">employee_id</item>
                </item>
            </argument>
        </field>
        <field name="employee_name">
            <argument name="data" xsi:type="array">
                <item name="config" xsi:type="array">
                    <item name="dataType" xsi:type="string">text</item>
                    <item name="label" xsi:type="string" translate="true">Employee Name</item>
                    <item name="formElement" xsi:type="string">input</item>
                    <item name="source" xsi:type="string">employee</item>
                    <item name="dataScope" xsi:type="string">employee_name</item>
                </item>
            </argument>
        </field>
        <field name="employee_salary">
            <argument name="data" xsi:type="array">
                <item name="config" xsi:type="array">
                    <item name="dataType" xsi:type="string">text</item>
                    <item name="label" xsi:type="string" translate="true">Employee Salary</item>
                    <item name="formElement" xsi:type="string">input</item>
                    <item name="source" xsi:type="string">employee</item>
                    <item name="dataScope" xsi:type="string">employee_salary</item>
                </item>
            </argument>
        </field>
        <field name="employee_address">
            <argument name="data" xsi:type="array">
                <item name="config" xsi:type="array">
                    <item name="dataType" xsi:type="string">text</item>
                    <item name="label" xsi:type="string" translate="true">Employee Address</item>
                    <item name="formElement" xsi:type="string">textarea</item>
                    <item name="source" xsi:type="string">employee</item>
                    <item name="dataScope" xsi:type="string">employee_address</item>
                </item>
            </argument>
        </field>
    </fieldset>
</form>

Step 5: Create DataProvider.php File In Magemeta/UiForm/Model Folder

Last step, you need to create DataProvider.php file in Magemeta/UiForm/Model folder.

<?php
namespace Magemeta\UiForm\Model;
 
use Magemeta\UiForm\Model\ResourceModel\Employee\CollectionFactory;
 
class DataProvider extends \Magento\Ui\DataProvider\AbstractDataProvider
{
    /**
     * @param string $name
     * @param string $primaryFieldName
     * @param string $requestFieldName
     * @param CollectionFactory $employeeCollectionFactory
     * @param array $meta
     * @param array $data
     */
    public function __construct(
        $name,
        $primaryFieldName,
        $requestFieldName,
        CollectionFactory $employeeCollectionFactory,
        array $meta = [],
        array $data = []
    ) {
        $this->collection = $employeeCollectionFactory->create();
        parent::__construct($name, $primaryFieldName, $requestFieldName, $meta, $data);
    }
 
    /**
     * Get data
     *
     * @return array
     */
    public function getData()
    {
        return [];
    }
}

After completing all above steps, your UI form is ready once you run setup:upgrade.

Hope this helps you guys!
