Code

In this example, we will use a field to get tags list, the number of tags dynamic.

Simple taxonomy autocomplete field.

Example:

$form['tagtest'] = [

  '#type' => 'entity_autocomplete',

  '#target_type' => 'taxonomy_term',

  '#title' => 'Taxonomy Term',

];

Completely reset

Delete the .git directory locally.

Recreate the git repository:

$ cd (project-directory)

$ git init

$ (add some files)

$ git add .

$ git commit -m 'Initial commit'

Example of a pager (pagination) on php:

function showpager($currentIndex = 0, $buttons = 5, $totalPages = 50) {

  $currentPage = $lowerLimit = $upperLimit = min($currentIndex, $totalPages);

  //Search boundaries



Note : On drupal the best practice is use drupal behaviors but not JS or Jquery codes such as:

<button onclick='myFunction()'>Click</button>

keyvalue.expirable service allow to save Key / Value variable in the database.

Example:

// Save without date limit.

\Drupal::service('keyvalue.expirable')->get('my_module')->set('my_var', 123);

Get HTTP Header information From JavaScript

Note : It's not possible to read the current headers. You could make another request to the same URL and read its headers, but there is no guarantee that the headers are exactly equal to the current.

Create a customizable text.

Example :

use Drupal\Component\Render\FormattableMarkup;

$text = new FormattableMarkup('My name is @name', ['@name' => "The name"]);

Drupal's event system allow to create triggers when an event has been happened like create a custom hook on drupal 7.

Use Event Subscriber service.

The EventSubscriber allow to execute an action on boot as hook_boot or hook_init of drupal 7.

Example.
