I know that I can programmatically create a user using the following code, in Drupal .

<?php

use Drupal\user\Entity\User;

// Create user object.
$user = User::create();

//Mandatory settings
$user->setPassword("password");
$user->enforceIsNew();
$user->setEmail("email");
$user->setUsername("username");
$user->addRole('role_name');
$user->set("field_machine_name", 'value');       
$user->save();

We know Taxonomy is a powerful core module and helps us categorize the content. A vocabulary in Drupal is essentially a container for terms that are used by the system. These terms are what Drupal uses to connect certain areas together within the website.

How do I create a role programmatically in Drupal 8+

//your data array
$data = array('id' => 'client', 'label' => 'Client');
//creating your role
$role = \Drupal\user\Entity\Role::create($data);
//saving your role
$role->save();

In my case, I wanted to be able to auto-create multiple roles ("clients","managers","salesrep") to work with my custom module.

This is how I auto-create roles programmatically in Drupal.

In the Drupal administration section, each theme has its own settings page at admin/appearance/settings/themeName. This page has a form with standard settings like “Logo image settings” and “Shortcut icon settings.”

Drush is the command line shell and Unix scripting interface for Drupal. The most common way to install Drush is to install it on a per-project basis using Composer. We'll walk through the steps to do that, as well as how to set up the Drush Launcher tool (to make it possible to execute Drush commands without having to specify a full path to the executable).

Run composer require

composer require drush/drush

Once that's completed run the command ./vendor/bin/drush --version to verify it worked.

Create patch or diff file from git repository and apply it to another different git repository

There are different ways to apply a Git patch. Let’s learn more about various Git Diff commands and how to create/apply a patch with the help of Git diff and Git apply. We will assume that you have already cloned/obtained a copy of the project in your local repository and have pulled the latest changes so you’re not working on an older version of the project. Take a look at some Github best practices here.

There are various ways you can add blocks to regions in pages in Drupal. You could add it in the block interface, use Panels or Context. But what if you just want to place a block directly in a Twig template?

The simplest way to place a block in a Twig template is to use the Twig Tweak module. Twig Tweak is a very handy module that gives you a range of functions to make theming with Twig easier.

Install Twig Tweak

This is how you can get the url of a field link rendered as a string (internal or external). 

<a href="{{ node.field_link.get(0).getUrl().toString() }}">{{ node.field_link.get(0).title }}</a>

Short snippet that shows how to get url parameters in drupal . to get query parameter form the url, you can us the following.

If you have the url for example /path?id=x

To get "id" from the url, use:

$id= \Drupal::request()->query->get('id');

This is how you can dynamically modify the content displayed in the "empty" area of your "custom" view when it's rendered as a block, based on the configuration's empty header text. Of course you can update the conditions as you think they fit better for you. You can put this into your web/modules/custom/custom.module file.

Although this is of course available from within views admin ui section, sometimes in production for example you might not provide for security reasons the views_ui module making it hard for modifying the empty header text message of a view.
