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>
<dataSource name="employee_form_data_source">
<argument name="dataProvider" xsi:type="configurableObject">
<argument name="class" xsi:type="string">Magemeta\UiForm\Model\DataProvider</argument>
<argument name="name" xsi:type="string">employee_form_data_source</argument>

<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!
