Zero1_LayoutXmlPlus

This module is aimed at reducing the need to override templates for blocks. For example, changing a single class for a button shouldn't require you to override the template. However for significant dom structure changes we would still recommend overriding the template.

Installation

composer require module enable setup:upgrade

Actions

The functionality has been split into "actions" different actions that can be taken on the output of a blocks html before it is passed to a user.

XPath Cheat Sheet

Other Recommendations

When it comes to stopping blocks outputting content, using layout xml can often remove the requirement to change the template. N.B when referencing a block you must use it's name and not it's alias Example dont do

<?= // $block->getChildHtml('review_form') ?>

do

<referenceBlock name="product.review.form" display="false"></referenceBlock>
