Override Custom Theme Layout File with one in Module?

Question

I have a custom layout file mytheme/default/magento_theme/layout/custom_cms_name.xml

I need to override with a theme file from my custom module:

/companyname/modulename/frontend/layout/

I tested and "/companyname/modulename/frontend/layout/cms_page_view_id_idhere.xml" works so I know the module is working but /companyname/modulename/frontend/layout/custom_cms_name.xml does not work.

What naming convention can I use within my module to override custom layout form my theme ??

Answer 1

I think your path worng .You are missing view folder.For Example Check below

Your path is :-

/companyname/modulename/frontend/layout/custom_cms_name.xml

instand of :-

/companyname/modulename/view/frontend/layout/custom_cms_name.xml

And finally you test your xml file like this :-

<?xml version="1.0"?>
<page
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" layout="1column" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">
    <referenceContainer name="content">
        <block class="Companyname\Modulename\Block\Post" name="brand.list" template="Companyname_Modulename::yourfilename.phtml"/>
    </referenceContainer>
</page>

And Then run Below commands :-

php bin/magento s:up
php bin/magento s:s:d -f
php bin/magento c:c
php bin/magento c:f
