magento2 – Magento 2.3.4 Open tab on button click

I’d like to create, on the product page, a button that leads to a specific tab with id = “exampleid”like “Be the first to review this product”.
The phtml file is this:

// @codingStandardsIgnoreFile  

 * @var $block MagentoCatalogBlockProductView
    $_product = $block->getProduct();
        <?php if($_product->getData('exampleattribute')==1){?>
            <div id="exampleid">
               <?php echo $this->getLayout()->createBlock('MagentoCmsBlockBlock')->setBlockId('exampleblock')->toHtml();?>
        <?php } ?>

and the catalog_product_view.xml is this:

<?xml version="1.0"?>

<page xmlns:xsi="" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">
        <referenceBlock name="">
            <block class="MagentoCatalogBlockProductView" name="" template="Vendor_extension::exampletab.phtml" group="detailed_info">
                    <argument name="title" translate="true" xsi:type="string">Example tab</argument>
                    <argument name="sort_order" xsi:type="string">25</argument>                    

what is the correct and clean way to create a link that calls the id of the tab?
Thanks a lot to everyone đŸ˜‰

Less file not included on frontend. Magento 2.3.4

I’ve got a really strange issue, If I choose to minify or merge css, then my site breaks, but not straight away, it seems to take some time and then eventually style-l.css just doesn’t get included on the frontend.

The file is still generated, but just not included on the front end, but it seems to happen after time (or after heavy load?).

I can’t see to work out why it wouldn’t be included. When the site breaks, the style-l.css link is still accessible – so it’s not as if the file is then missing.

Has anyone come across this before? Tearing my hair out as there are no error messages anywhere in the logs. I can’t even work out when the site will break or what I can do to make it break to begin testing, it’s completely random.

Using magento 2.3.4, Smartwave Porto theme patched to the latest version.

magento2 – Magento 2.3.4 – The status of the shipment is always empty

I am using Magento 2.3.4 and I see in the sales_shipment table that there is a field called shipping status. This field is empty, but if I look in the model, I saw that there is a default value "New". So how does this field work? – For my needs I need a state at the shimpment but I don't make it work!

Custom email template, use user ID. Magento 2.3.4

I want to use the username / username in personalized emails, when I use {{trans "% name," name = $}} , I receive an empty field.

Should I create custom variables for this data?

Reinstall Magento 2.3.4 on an existing store without losing products, categories, design, etc.

After installing a new theme as a new store view, most of my product images (around 1000) will not show up on the new store view. They show OK on the view of the original store with the old theme.
It is suggested that I probably have incorrect rewrites because when I look at the images I see that sometimes magento searches for them in the wrong cache folder and sometimes it looks for an image with the wrong name.
Additionally, some of the original store view images that are works don't exist in the magento cache folder at all, so they can't work, so it looks like they be retrieved from the cache, cdn or something.

the image resize command did not help.

Can reinstalling magento (2.3.4) help? without losing all my configurations?
