Adding Custom tab to product page dependant on category in Magento 2.2.1

Question

I have used the following code

(https://www.cloudways.com/blog/add-custom-tab-product-page-magento-2/)

to create a module that adds a custom tab to our product pages. It works perfectly but I need to somehow change the module so that the custom tab only display on products in certain categories. Has anyone any suggestions on how to do this? Don't mind if the category numbers need to be hard coded as there won't be many! Please note we are using Magento 2.2.1

Try replacing code after <?php if ($_attributeValue): ?>, in attribute.phtml with following:

<?php if ($_attributeValue): ?>
<?php if ($_attributeType === 'your_type'):
    $objectManager = \Magento\Framework\App\ObjectManager::getInstance();
    $category = $objectManager->get('Magento\Framework\Registry')->registry('current_category');
    if (strtolower($category->getName()) === 'category_to_display'): ?>
        <?php /* @escapeNotVerified */ echo $_attributeValue; ?> <!-- add your tab logic here -->
    <?php endif; ?>
<?php else: ?>
<div class="product attribute <?php /* @escapeNotVerified */ echo $_className?>">
    <?php if ($_attributeLabel != __('none')): ?><strong class="type"><?php /* @escapeNotVerified */ echo $_attributeLabel?></strong><?php endif; ?>
    <div class="value" <?php /* @escapeNotVerified */ echo $_attributeAddAttribute;?>><?php /* @escapeNotVerified */ echo $_attributeValue; ?></div>
</div>
<?php endif; ?>    
<?php endif; ?>

change your_type to your declared attribute type, change category_to_display to your desired category name (chain || to add more categories to include tab). Add your code to add your tab logic here
