Adding Fields to Inline Entity Form Table

/ June 28, 2018

Inline Entity Form is a useful module for reference entities and being able to edit them in place.

Here’s what the edit form looks like out of the box for an unlimited value entity reference:

Often it’s helpful to provide additional information to your editors.

If you have a look at inline_entity_form.module you will find a function called theme_inline_entity_form_entity_table(). Within this you will see how this table is built, and how you can manipulate the form to add additional columns of information.

Using the Messenger Service Instead of drupal_set_message in Drupal 8

/ June 7, 2018

As you may know, drupal_set_message() is deprecated in Drupal 8.5.0.

Here’s a quick example of using dependency injection to use the new Messenger service:

mymodule.services.yml

services:
  mymodule.authentication:
    class: Drupal\mymodule\MymoduleAuthentication
    arguments: ['@messenger']

services:

mymodule.authentication:

class: Drupal\mymodule\MymoduleAuthentication

arguments: ['@messenger']

src/MymoduleAuthentication.php

<?php

namespace Drupal\mymodule;

use Drupal\Core\Messenger\MessengerInterface;

/**
 * Provides authentication functionality for my module.
 *
 * @package Drupal\mymodule
 */
class MymoduleAuthentication {

  /**
   * Include the messenger service.
   *
   * @var \Drupal\Core\Messenger\MessengerInterface
   */
  protected $messenger;

  /**
   * Constructor.
   */
  public function __construct(MessengerInterface $messenger) {
    $this->messenger = $messenger;
  }

  /**
   * Shows a "Hello, world" message.
   */
  private function showHelloWorldMessage() {
    $this->messenger->addMessage('Hello, world');
  }

}

<?php

namespace Drupal\mymodule;

use Drupal\Core\Messenger\MessengerInterface;

/**

* Provides authentication functionality for my module.

* @package Drupal\mymodule

class MymoduleAuthentication {

/**

* Include the messenger service.

* @var \Drupal\Core\Messenger\MessengerInterface

protected $messenger;

/**

* Constructor.

public function __construct(MessengerInterface $messenger) {

$this->messenger = $messenger;

}

/**

* Shows a "Hello, world" message.

private function showHelloWorldMessage() {

$this->messenger->addMessage('Hello, world');

}

Automatically Put Files Into a YYYY/MM Directory Structure

/ June 6, 2018

#!/usr/bin/env bash

## This script will find .sql and .gz files in the current
## directory and move them into YYYY/MM directories (created
## automatically).

BASE_DIR=$(pwd)

## Find all .sql and .gz files in the current directory
find "$BASE_DIR" -maxdepth 1 -type f -name "*.sql" -o -name "*.gz" |
 while IFS= read -r file; do

    ## Get the file's modification year
    year=$(date -d "$(stat -c %y $file)" +%Y)

    ## Get the file's modification month
    month=$(date -d "$(stat -c %y $file)" +%m)

    ## Create the YYYY/MM directories if they don't exist. The -p flag
    ## makes 'mkdir' create the parent directories as needed so
