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" />

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

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

  • What you want to change in your custom block? – Suresh Chikani Aug 8 '17 at 11:46
  • Right now, I just want to add text (Demo Text) which I have written in ContactForm.php. I just want to check whether the block is overridden or not – Syed Muneeb Ul Hasan Aug 8 '17 at 11:48

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";
return $this->getUrl('contact/index/post', ['_secure' => true]);

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

Copy file from


and put it to


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

  • Where to write exit? I can't get it – Syed Muneeb Ul Hasan Aug 8 '17 at 11:57

  • Actually I want to show text on contact form – Syed Muneeb Ul Hasan Aug 8 '17 at 12:01
  • No need to modify core block. You can write directly in form.phtml file. – Suresh Chikani Aug 8 '17 at 12:03
  • If I want to show text on contact form using ContactForm.php (Block), then how can I do that? – Syed Muneeb Ul Hasan Aug 8 '17 at 12:27
