Magento 2: Custom module to override the logo.phtml file of the custom theme

Question

Naming the custom module to override the logo.phtml file found at the path seen in the screenshot below a bit confusing to me as the module name is too long to decide on the naming. The vendor of the custom theme being used is Swissup.

I know the module name should begin with Swissup_(What comes here) with me not being able to figure out how to complete the module name after Swissup_. Any advice or help, please.

Answer 1

You can override the logo.phtml file under your custom module by making preference for Magento\Theme\Block\Html\Header\Logo class.

Add di.xml file under app/code/Vendor/Module/etc/frontend/di.xml with below content.

<?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\Theme\Block\Html\Header\Logo" type="Vendor\Module\Block\Rewrite\Html\Header\Logo"/>
</config>

After that, create Logo.php under app/code/Vendor/Module/Block/Rewrite/Html/Header with below content.

<?php 

namespace Vendor\Module\Block\Rewrite\Html\Header;

class Logo extends \Magento\Theme\Block\Html\Header\Logo
{
    /**
     * Current template name
     *
     * @var string
     */
    protected $_template = 'Vendor_Module::html/header/logo.phtml';
}

Copy the logo.phtml file from your theme and placed under app/code/Vendor/Module/view/frontend/templates/html/header.

Run the deployment commands and check your changes.

Hope it helps!!!

You can manage via after plugin on getTemplate() .

Create di.xml at app/code/StackExchange/Theme/etc/frontend

<?xml version="1.0" ?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
    <type name="Magento\Theme\Block\Html\Header\Logo">
        <plugin disabled="false" name="StackExchange_Theme_Plugin_Magento_Theme_Block_Html_Header_Logo" sortOrder="10" type="StackExchange\Theme\Plugin\Magento\Theme\Block\Html\Header\Logo"/>
    </type>
</config>

Then on plugin class StackExchange\Theme\Plugin\Magento\Theme\Block\Html\Header\Logo.php and

from afterGetTemplate() changes template from here.

<?php  declare(strict_types=1);

namespace StackExchange\Theme\Plugin\Magento\Theme\Block\Html\Header;

class Logo
{

    public function afterGetTemplate(
        \Magento\Theme\Block\Html\Header\Logo $subject,
        $result
    ) {

        return 'StackExchange_Theme::html/header/logo.phtml';
    }
}
