Submit a form in Magento 2 custom module?

Question

I created a custom module. There is a form which user submit. I want to capture the post data. So how to create a post route ?

This is my routes.xml

<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="../../../../../../lib/internal/Magento/Framework/App/etc/routes.xsd">
<router id="standard">
 <route id="contactus" frontName="contactus">
 <module name="My_ContactUs" />
 </route>
</router>

And I have only 1 controller which display the form.

• Mike: This should be routes.xml and not di.xml

Answer 1

create a controller Save.php and copy paste in your module.

<?php
namespace [Namespace]\[ModuleName]\Controller\Index;
class Save extends \Magento\Framework\App\Action\Action
{
 /**
 * @var \Magento\Framework\View\Result\PageFactory
 */
 protected $resultPageFactory;
 /**
 * @param \Magento\Framework\App\Action\Context $context
 * @param \Magento\Framework\View\Result\PageFactory $resultPageFactory
 */
 public function __construct(
 \Magento\Framework\App\Action\Context $context,
 \Magento\Framework\View\Result\PageFactory $resultPageFactory
 )
 {
 $this->resultPageFactory = $resultPageFactory;
 parent::__construct($context);
 }
 /**
 * Default customer account page
 *
 * @return void
 */
 public function execute()
 {
 /** @var \Magento\Framework\Controller\Result\Redirect $resultRedirect */
 $resultRedirect = $this->resultRedirectFactory->create();
 try{
 $request = $this->getRequest()->getParams(); 
 $email = $request['email'];
 $this->resultPageFactory->create();
 return $resultRedirect->setPath('contactus/index/index');
 }catch (\Exception $e){
 $this->messageManager->addExceptionMessage($e, __('We can\'t submit your request, Please try again.'));
 $this->_objectManager->get('Psr\Log\LoggerInterface')->critical($e);
 return $resultRedirect->setPath('contactus/index/index');
 }
 }
}
?>

create save.phtml file from [Namespace]/[ModuleName/view/frontend/templates and copy paste it below code.

 <?php
 $objectManager = \Magento\Framework\App\ObjectManager::getInstance();
 $storeManager = $objectManager->create('\Magento\Store\Model\StoreManagerInterface');
 $baseURL_l = $social_image_url = $storeManager->getStore()->getBaseUrl();
 ?>
 <form action="<?php /* @escapeNotVerified */ echo $baseURL_l . 'contactus/index/save' ?>" method="post" id="form-validate" enctype="multipart/form-data" autocomplete="off" data-mage-init='{"validation":{}}' data-hasrequired="<?php /* @escapeNotVerified */ echo __('* Required Fields') ?>">
 <div class="field required">
 <label for="email_address" class="label"><span><?php /* @escapeNotVerified */ echo __('Email') ?></span><span class="span">*</span></label>
 <div class="control">
 <input type="email" name="email" autocomplete="email" id="email_address" value="" title="<?php /* @escapeNotVerified */ echo __('Email') ?>" class="input-text" data-validate="{required:true, 'validate-email':true}">
 </div>
 </div><br/>
 <div class="primary">
 <button type="submit" class="action submit primary" title="<?php /* @escapeNotVerified */ echo __('Submit') ?>"><span><?php /* @escapeNotVerified */ echo __('Submit') ?></span></button>
 </div>
 </form>

Now enter the email and hit the Submit button you will get the email $request['email'] this variable. So you can do it from your logic.
