Accessing taxonomy's name and parent TID in Drupal 8

This function allows you to access a taxonomy entity fields and get the following results. The child's parents TID, the TID, and the field's string name of the TID being requested.  The results are placed into an array and custom keys can be used when being iterated over.

It works in Drupal 8 but I have access the fields using name spacing and avoided depreciated Drupal 8 functions and methods so it should be future proofed for Drupal 9

How to stop a specific block from being cached in Drupal 8

If you have a block in Drupal 8 that needs to update its contents every time there is a page load then use the hook and code below.

On a Drupal 8 website we developed, it needed to swap out different menus depending on the page that was being requested. We found that Drupal was caching the block twig logic and the only way we could get the menus to swap was keep clearing the cache. To stop this from happening we added ['max-age'] = 0 to the right part of the block render array and all the caching on the block type stopped.

Accessing a block types content programatically

For anyone who is looking to access Block Fields programmatically that were created in block content in Drupal 8, this function will achieve that and will also allow you to access the files URL created in the "block content" image field if it exists. This uses Drupals new namespacing so it should work into the future with Drupal 9

I created a block type in Drupal 8's UI (structure/block/block-content/types ) and added the fields. To access block type in hook_preprocessor_html programmatically you can use the following function

Learn to use vim and forget the plugins

The more and more I use vim the quicker my productivity becomes this has allowed me streamlined my development tool chain. One of the issues over the years I kept finding myself doing is extending vims functionality to make it work like an IDE and more mouse friendly. I happen to find these videos on how to use vim from Derek Wyatt.org.

To my amazement I found that I had missed the whole point of vim. Using buffers instead of tabs and learning how to navigate and edit without using the arrow keys and a mouse has really shown me the power off vim.
