The problem is I have the vendor name capitalized, and then, don't know why the overrides don't work. Only when you want to change the template but still using default block. For example:

Override the catalog_product_view (single product page - the image)

Folders structure:

    │   registration.php
    │       module.xml
            │       catalog_product_view.xml




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


<?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">
        <referenceBlock name="product.info.media.image" template="GST_Override::product/view/gallery.phtml"/>


<p> test </p>

Expected result: No image shown and display 'test'

Actual result: Default magento view

What I've tried:

1) If I use remove attribute on layout:

<referenceBlock name="product.info.media.image" template="GST_Override::product/view/gallery.phtml" remove="true"/>

The image is removed.

2) If I use custom block on layout:

<referenceBlock class="GST\Override\Block\Product\View\Gallery" name="product.info.media.image" template="GST_Override::product/view/gallery.phtml" remove="true"/>

It works.

3) Definately, if I use a 'normal' vendor name like Test it works.

Is this a kind of bug? should I never use all capital leters to name vendor or module? Did I make a mistake? Can you reproduce this error or it's just me?

Capitalizing vendor name is not a problem. But for our own convenience we will be using first letter as capital.

  • Yep, but now I have made enough modules with this namespacing. And the thing is, I have some overrides like this that aren't working, I'd need to create another vendor or something else bc I cannot solve this.

Looks like the problem not in module name and in module load sequence.

Try add to module.xml

        <module name="Magento_Catalog"/>
        <module name="Magento_ProductVideo"/>
  • Tried, doesn't work.
