Blog Posts How to Create Module in Magento 2

by Cozmot | Nov 5, 2020 | Magento2

Magento 2 CMS is an excellent option to develop an online store. However, it may not be enough for modern business requirements. To overcome the default limitations, there are Magento 2 extensions available in the market that extend the functionality of Magento 2. You can also opt to create module in Magento 2 rather than approaching any third party extension providers. However, you may have tons of questions regarding Magento 2 module development such as how one can develop Magento 2 module that helps the Magento 2 store to increase store facility, what are the most important things for the development of a module and so on. Well, don’t worry. Here we have prepared a comprehensive guide on creating your first Magento 2 module. To create a module or extension in Magento 2, you need to create these important files.

module.xml
registration.php

But, before getting started, let’s discuss some of the basic things that you need to know. The extension is built under app/code. When you go through this path, the first folder name demonstrates the name of the extension provider company. The second folder shows the name of the extension. For easy explanation, we are here giving the name of extension “Extension” and the name of a company “Meetanshi”. Alright. So coming back to the important files. What you need to do is create a file having a specific path.

Steps to create a module in Magento 2:

1. Create module.xml at app/code/Cozmot/Extension/etc In module.xml file, copy and paste this code.

<?xml version=“1.0”?>

<config xmlns:xsi=“http://www.w3.org/2001/XMLSchema-instance”

xsi:noNamespaceSchemaLocation=“../../../../../lib/internal/Magento/Framework/Module/etc/module.xsd”>

</module>

</config>

Now, you also need to create a file that is registration.php. 2. Create registration.php at app/code/Cozmot/Extension

<?php

use Magento\Framework\Component\ComponentRegistrar;

ComponentRegistrar::register(

ComponentRegistrar::MODULE,

‘Cozmot_Extension’,

__DIR__

);

These two files are mandatory to create and get started with extension development. After creating module.xml and registration.php files, the next step is to execute commands in the command line.

php bin/magento setup:upgrade

php bin/magento setup:static–content:deploy –f

php bin/magento cache:flush

Run these three commands and your extension will appear in app/etc/config.php. If the command gives output ‘0’, that indicates the extension is disabled. On the other hand, if the command shows output ‘1″, it explains that the extension is enabled and all the functionalities of the extension are working smoothly.

The image explains that the name of the extension “Meetanshi_Extension” is enabled. That’s it. In the next tutorial, you will learn how to display a message on the frontend. However, if you do not want the hassle of creating an extension on your own, you can visit COZMOT for top-notch extensions developed by certified Magento developers!

How to Save Form Data to the Custom Table in Magento 2

by Cozmot | Nov 5, 2020 | Magento2

save form data to the custom table in Magento 2. When you fill out details in a form and click on a Submit button, the data has to be stored in a table. To do that, you will need to create Submit.php file. For instance, if you want to collect name, email addresses and telephone number of customers for sending newsletters, the data should be stored in a database. If the data is not stored in the database, we simply cannot access and send newsletters. Learn the programmatic method as shown below:

use Magento\Framework\View\Result\PageFactory;

use Meetanshi\Extension\Model\ExtensionFactory;

use Magento\Framework\Controller\ResultFactory;

use Magento\Framework\App\Action\Action;

class Submit extends Action

{

protected $resultPageFactory;

protected $extensionFactory;

public function __construct(

Context $context,

PageFactory $resultPageFactory,

ExtensionFactory $extensionFactory

)

{

$this->resultPageFactory = $resultPageFactory;

$this->extensionFactory = $extensionFactory;

parent::__construct($context);

}

public function execute()

{

try {

$data = (array)$this->getRequest()->getPost();

if ($data) {

$model = $this->extensionFactory->create();

$model->setData($data)->save();

$this->messageManager->addSuccessMessage(__(“Data Saved Successfully.”));

}

} catch (\Exception $e) {

$this->messageManager->addErrorMessage($e, __(“We can\’t submit your request, Please try again.”));

}

$resultRedirect = $this->resultFactory->create(ResultFactory::TYPE_REDIRECT);

$resultRedirect->setUrl($this->_redirect->getRefererUrl());

return $resultRedirect;

}

Implement the code and you will be able to save data in the database. As we have written the message “Data Saved Successfully” to display while submitting the data, the same message will appear when the data is being saved.

That’s it. If you have queries regarding this blog, feel free to ask in the Comment section below. I will try my level best to solve your problem. Do consider sharing this blog post with the beginners who are willing to learn Magento extension development. Thank you.]]>
