DrupalHeadless

Description

The DrupalHeadless project provides the following components as a compatible PSR-4 package:

• The original Drupal 7 Database Abstraction Layer
• A replacement for the Entity Field Query

This package was created in order to provide an elegant and suitable way of interact with Drupal 7 databases without the requeriment of install a full Drupal 7 stack. DrupalHeadless can used as with standalone scripts or can be deployed via composer in different solutions like for example Drupal 8.

How to use the database abstraction layer?

If you are familiar with Drupal 7 Database API, then it is going to be easy for you to use the DrupalHeadless database abstraction layer because it is based in the original abstraction layer.

Database connection and query

 use \DrupalHeadless\Database\Database;

 // Set connection info
 Database::addConnectionInfo('default', 'default', [
     'driver'    => 'mysql',
     'database'  => 'drupal',
     'username'  => 'root',
     'password'  => 'root',
     'host'      => '127.0.0.1',
     'prefix'    => 'drupal_'
 ]);

 $query = Database::getConnection('default', 'default');

 $st = $query->select('node', 'n');

 $result = $st->fields('n')
     ->range(0, 10)
     ->execute()
     ->fetchAll();

As an alternative it is also possible to use the statement helper:

 use \DrupalHeadless\Database\Database;
 use \DrupalHeadless\Database\DatabaseHelper as DH; 

 // Set connection info
 Database::addConnectionInfo('default', 'default', [
     'driver'    => 'mysql',
     'database'  => 'drupal',
     'username'  => 'root',
     'password'  => 'root',
     'host'      => '127.0.0.1',
     'prefix'    => 'drupal_'
 ]);


 $result = DH::select('node', 'n')
     ->fields('n')
     ->range(0, 10)
     ->execute()
     ->fetchAllAssoc('nid');

How to use the Entity Field Query?

Select (and retrieve all the fields)

    use \DrupalHeadless\Database\Database;
    use \DrupalHeadless\Entity\EntityController as EC;
    use \DrupalHeadless\Entity\Model;


    // Set connection info
    Database::addConnectionInfo('default', 'default', [
        'driver'    => 'mysql',
        'database'  => 'drupal',
        'username'  => 'root',
        'password'  => 'root',
        'host'      => '127.0.0.1',
        'prefix'    => 'drupal_'
    ]);


    $connection = Database::getConnection('default', 'default');


    // Search the first 5 nodes with bundle "article" that contain the word "Test" into the body field
    $result_node = EC::entity($connection, new Model\Node(), 'article')
        ->load()
        ->fieldCondition('body', 'value', '%Test%', 'LIKE')
        ->range(0, 5)
        ->fetchAll();


    // Search the user with UID = 1 
    $result_user = EC::entity($connection, new Model\Users(), 'user')
        ->load()
        ->propertyCondition('uid', 1)
        ->fetch();

Insert

use \DrupalHeadless\Database\Database;
use \DrupalHeadless\Entity\EntityController as EC;
use \DrupalHeadless\Entity\Model;


// Set connection info
Database::addConnectionInfo('default', 'default', [
    'driver'    => 'mysql',
    'database'  => 'drupal',
    'username'  => 'root',
    'password'  => 'root',
    'host'      => '127.0.0.1',
    'prefix'    => 'drupal_'
]);


$connection = Database::getConnection('default', 'default');


$entity = EC::entity($connection, new Model\Node(), 'article');


// Load entity node and bundle "article" which "title" is equal to "This is a test"
$result_node = $entity->load()
    ->propertyCondition('title', 'This is test')
    ->fetch();


// Insert into the custom/dynamic field the value "myvideo"
$entity = $entity->insertFieldset('field_videoid', $result_node->nid, ['value' => 'myvideo'], 0);
