Hook form with build validate and submit

Context

EK application has a module that store personal documents for user. When user account is deleted, those documents may be transferred to another account.

To achieve that, we need to alter the user account cancel form when building the form, validating and submitting it.

Let's review the 3 steps.

 

BUILD

The form before altering it looks like this

cancel user account before hook

To achieve that we Implements hook_form_alter() in MyModule.module:

Custom Block in Drupal 8

In this article, we will see how we built custom blocks in EK management tools suite with a sample basic block in a module called 'mymodule' used for demo. It can be used to display multiple content, static or dynamic as in the example above.

Create the block script

First we will create a script that will display some content within a block. the script file will be called MyBlock.php and is placed in /mymodule/src/Plugin/Block/.


/**
 * @file
 * Contains \Drupal\mymodule\Plugin\Block\MyBlock.
 */
namespace Drupal\mymodule\Plugin\Block;
use Drupal\Core\Block\BlockBase;
use Drupal\Core\Session\AccountInterface;
use Drupal\Core\Access\AccessResult;

/**
 * Provides a 'Custom module widget' .
 *
 * @Block(
 *   id = "my_block",
 *   admin_label = @Translation("My custom block"),
 *   category = @Translation("mymodule Widgets")
 * )
 */

Install and use Swift Mailer in Drupal 8 (part 1 : dependency)

In a previous post from 2015, we described usage of Swift Mailer module to send HTML mail and mail with attachment. At this time, the module was not yet available for Drupal 8.

There is now a version alpha1 available. Let's go through installation process.

Because it has been rather tedious for us, we will try to explain the flow of the process as much as possible to help you save time.

 

1) Composer

 

The prerequisite is the installation of composer.

In our case we installed first on Windows inside a folder named  F:\Program Files\composer2\.

The installation exe for Windows can be found here.

Drupal 8 Guided Tour module

In Drupal 8 there is a Tour module in core that is very useful when it comes to web applications. In EK management tools we target professional users with small to medium scale companies. They usually have limited resources and time to spend on back office trainings. This is where the Tour module is very convenient to introduce functionalities to users who can quickly grasp the functions available to manage their back office.

We use the Tour functionality in our pages to guide users in their daily tasks like for instance in the form to create a new invoice or project page:
