Drupal 8 - Remove configuration from database
drush ev "\Drupal::configFactory()->getEditable('configuration.name')->delete();"
RuntimeException: Unable to determine class for field type found in the configuration
drush sqlq "DELETE FROM cache_config"
drush sqlq "DELETE FROM config WHERE name = 'field.storage.<module_name>.<field_machine_name>' OR data LIKE '%field.storage.<module_name>.<field_machine_name>%'"
drush sqlq "DELETE FROM config_snapshot WHERE name = 'field.storage.<module_name>.<field_machine_name>' OR data LIKE '%field.storage.<module_name>.<field_machine_name>%'"
On my case It was happening with "taxonomy_term" module and field named "field_location".
Drupal 8 - Load file entity by URI
/* @var \Drupal\file\FileInterface[] $files */
$files = \Drupal::entityTypeManager()
->getStorage('file')
->loadByProperties(['uri' => $uri]);
Drupal 8 fix-permissions.sh
Script:
#!/bin/bash
# Help menu
print_help() {
cat <<-HELP
This script is used to fix permissions of a Drupal installation
you need to provide the following arguments:
1) Path to your Drupal installation.
2) Username of the user that you want to give files/directories ownership.
3) HTTPD group name (defaults to www-data for Apache).
Usage: (sudo) bash ${0##*/} --drupal_path=PATH --drupal_user=USER --httpd_group=GROUP
Example: (sudo) bash ${0##*/} --drupal_path=/usr/local/apache2/htdocs --drupal_user=john --httpd_group=www-data

Drupal 8 - Sort multi arrays

// Also It's possible to use without a closure function
uasort($form['elements'], [

Drupal 7 - Retrieve field value properly
/** @var array $field_items */
$field_items = field_get_items('node', $node, 'FIELD_MACHINE_NAME');
/** @var array $field_value */
$field_value = (!empty($field_items)) ? reset($field_items) : [];
Drupal 7 - Retrieve current node object
// On the page node/%node, the router loads the %node object
if($node = menu_get_object()) {
echo '<pre>' . print_r($node, 1);
