I've been trying to add a block to the footer but so far it keeps returning Invalid block type: [Namespace]\[Module]\Block\Timeline

The source of what I have so far can also be found here: https://github.com/sandermangel/magento2-twitterfeed

my layout/default.xml

<?xml version="1.0"?>
<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">
    <body>
        <referenceBlock name="footer">
            <block class="[Namespace]\[Module]\Block\Timeline" name="twitterfeed-timeline" template="footer/timeline.phtml"></block>
        </referenceBlock>
    </body>
</page>

and my block class in vendor/[namespace]/[module]/Block/Timeline.php

namespace [Namespace]\[Module]\Block;

use Magento\Framework\View\Element\Template;

class Timeline extends Template
{

    /**
     * Timeline constructor.
     * @param Template\Context $context
     * @param array $data
     */
    public function __construct(
        Template\Context $context,
        array $data = []
    ) {
        parent::__construct($context, $data);
    }

    /**
     * @return mixed
     */
    public function getTweets()
    {
        // ---
    }
}

composer.json

And the exception.log error

Any idea on what might be wrong is appreciated

  • 'vendor/[namespace]/[module]/Block/Timeline.php' this path should be 'app/code/[Namespace]/[Module]/Block/Timeline.php' – Sohel Rana Nov 29 '15 at 17:16
  • Do you have errors in logs? – KAndy Nov 29 '15 at 17:33
  • @KAndy I've updated with the exception log. It's the error + backtrace – Sander Mangel Nov 29 '15 at 17:49
  • It means that your class cannot be loaded. Do you have you module registered in composer? Can you add composer.json. – KAndy Nov 29 '15 at 17:57
  • @KAndy sorry for the late reply. Added the composer.json. You're right. It fails to get an instance in Magento\Framework\View\Layout\Generator\Block::getBlockInstance but I wasn't able to determine why – Sander Mangel Nov 29 '15 at 20:59

I defined a use in the block class before the class definition. In this use I forgot a leading \ which cases an error. But since that error is caught and suppressed in Magento\Framework\View\Layout\Generator\Block::getBlockInstance it throws a completely unrelated error.

In short: causing a PHP error above the class definition will always result in the Invalid block type: error

  • I also had a similar problem now: I forgot to declare some "use" statements for some classes. The reported "Invalid block type" had nothing to do with the real problem. It took me a long time to figure it out. – peedee May 4 '16 at 10:33

To me was fixed when I changed the name of the file to the same of the class name and XML call. Like this:

app/code/Rafaelcg/Smartlook/view/frontend/layout/default.xml

<referenceContainer name="after.body.start">
            <block class="Rafaelcg\Smartlook\Block\Code" name="smartlook" as="smartlook" template="smartlook.phtml"/>
 </referenceContainer>

app/code/Rafaelcg/Smartlook/Block/Code.php

<?php   

namespace Rafaelcg\Smartlook\Block;

use \Magento\Framework\View\Element\Template;

class Code extends Template
{
