I seem to be missing something when it comes to overriding controllers. This is a somewhat recurring question in here, but nothing I've found in other questions worked for me, so either they might be a bit outdated or I am missing something obvious. I am on Magento 2.3.4, trying to override Magento's module-contact functionality.

Here's what I've done:

Created a new module in /app/code/vendor/module. Checked that the module shows up in module manager / php magento module:status. Created etc/di.xml with the following code

<?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\Controller\Index\Post" type="Vendor\Module\Controller\Index\ExtendIndex" />

Created etc/module.xml

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Module/etc/module.xsd">
    <module name="Module" setup_version="1.0.0">
            <module name="Magento_Contact"/>

Created /Controller/Index/ExtendIndex.php with minor functionality for testing

namespace Vendor\Module\Controller\Index;
class ExtendIndex extends \Magento\Contact\Controller\Index\Post
    public function execute($coreRoute = null)

    echo "1";
        $this->messageManager->addSuccess('Message from new controller.');
        return parent::execute($coreRoute);

Then flushed Magento Cache

Despite all that, which seems to be every step needed for this to work, it hasn't, and I've tried all minor variations in terms of code I could think, as it could simply be a "" somewhere that shouldn't be be or similar.

What am I missing here?

Firstly I see some concern/ The name of the modules folders must be capitalized as follows:


The name of the module in the module.xml file be as follows

<module name="Vendor_Module" setup_version="1.0.0">
  • Thanks for your reply. But everything on the code is correct, name wise (as in, capitalizations and such). I see some is indeed wrong in the text here but is just because I typed vendor/module when writing the question instead of copy pasting the names. Anyways I double checked that after your reply and still no dice Nov 12, 2021 at 20:32
  • Very important you have Vendor_Module dans module.xml, can you edit the question with the correct code or with the same code you have Nov 13, 2021 at 7:17
