Want to override Magento 2 Contact Form Block

Question

I have created a custom module app/code/Demo/Mymodule and I want to override Contact Form Block.

After configuration and registration of module, I have Created di.xml in app/code/Demo/Mymodule/etc

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
<preference for="Magento\Contact\Block\ContactForm" type="Demo\Mymodule\Block\ContactForm" />
</config>

Then, I have created ContactForm.php in app/code/Demo/Mymodule/Block

<?php
namespace Demo\Mymodule\Block;
use Magento\Framework\View\Element\Template;
class ContactForm extends \Magento\Contact\Block\ContactForm{
public function getFormAction()    {
echo "Demo Text";
return $this->getUrl('contact/index/post', ['_secure' => true]);
}
}

I have run all the commands like:

php bin/magento setup:upgrade
php bin/magento cache:clean

But, I am not getting output (Demo Text) on contact page

Answer 1

I have checked your code, it's working

You can see "Demo Text" before in form action. You can view it by inspect element.

Contact form action like this in inspect element

<form class="form contact" action="Demo Texthttp://

Also you can test it by write exit; just after "Demo Text" in your custom block.

public function getFormAction()    {
echo "Demo Text";
exit;
return $this->getUrl('contact/index/post', ['_secure' => true]);
}

If you show text on contact form, see below solution for it

Copy file from

vendor/magento/module-contact/view/frontend/templates/form.phtml

and put it to

app/design/frontend/Vendor/YourTheme/Magento_Contact/templates/form.phtml

You can change contact us form from this file, write a code as per you need.
