Manage your entities and repositories with this simple repository manager. An all in one solution for building repositories and entities.

Basic examples

Create your first entity

The entity will contain the data for a specific object (Also known as DAO) and will mediate between the application and the database. An entity has to use getters and setters.

<?php

namespace YourProject\People;

use InternetPixels\RepositoryManager\Entities\AbstractEntity;
use InternetPixels\RepositoryManager\Entities\EntityInterface;

class PersonEntity extends AbstractEntity implements EntityInterface
{

    /**
     * @var string
     */
    private $name;

    /**
     * @var int
     */
    private $age;

    /**
     * @return string
     */
    public function getName(): string
    {
        return $this->name;
    }

    /**
     * @param string $name
     */
    public function setName(string $name)
    {
        $this->name = $name;
    }

    /**
     * @return int
     */
    public function getAge(): int
    {
        return $this->age;
    }

    /**
     * @param int $age
     */
    public function setAge(int $age)
    {
        $this->age = $age;
    }
}

Create your first repository

A repository will handle all data transfers between an entity and your database. The repository will build queries to execute those actions.

Note: The entityName needs to map to your database table name.

<?php

namespace YourProject\People;

use InternetPixels\RepositoryManager\Entities\AbstractEntity;
use InternetPixels\RepositoryManager\Factories\EntityFactory;
use InternetPixels\RepositoryManager\Repositories\AbstractRepository;

class PeopleRepository extends AbstractRepository
{

    protected $entityName = 'people';

    public function update(AbstractEntity $entity)
    {
        $query = $this->queryBuilder->new($this->entityName)
            ->update([
                'name' => $this->dataManager->sanitize($entity->getName()),
                'age' => $this->dataManager->sanitize($entity->getAge()),
            ])
            ->where(['id' => $entity->getId()])
            ->limit(1)
            ->get();

        return $this->executeQuery($query);
    }
    
    /**
     * @param array $data
     * @return PersonEntity
     */
    protected function dataToEntity(array $data): PersonEntity
    {    
        /** @var PersonEntity $entity */
        $entity = EntityFactory::create('people');

        $entity->setName($data['name']);
        $entity->setAge($data['age']);
        
        return $entity;
    }
}

Register the Data manager

You only need to register the RepositoryDataManager and the new entity in the EntityFactory. The Data manager needs an (existing) Mysqli connection.

$mysqliConnection = new \Mysqli(
    $config['mysql.host'],
    $config['mysql.user'],
    $config['mysql.password'],
    $config['mysql.database']
);

$repositoryDataManager = new \InternetPixels\RepositoryManager\Managers\RepositoryDataManager($mysqliConnection);

// Add all your entities:
\InternetPixels\RepositoryManager\Factories\EntityFactory::register('people', new PersonEntity());

$peopleRepository = new PeopleRepository($repositoryDataManager);

Usage of the repository

In a service of your application you can implement the PeopleRepository and use them for basic CRUD actions or your custom implementations.

$peopleRepository = new PeopleRepository($repositoryDataManager);

// Get all records:
$people = $peopleRepository->read();

// Update a person
$person = EntityFactory::create('people');
$person->setId(1);
$person->setName('Person name');
$person->setAge(26); // update the age

$peopleRepository->update($person);

// Delete a person
$person = EntityFactory::create('people');
$person->setId(1);

$peopleRepository->delete($person);

Usage of the SQL Query builder

This package contains a simple query builder. Please use the functionality to prevent basic SQL issues.

// Sanitize input in a repository before pushing to the database:
$safe = $this->dataManager->sanitize($entity->getName());

// Build a new select query in a repository
$query = $this->queryBuilder->new($this->entityName)
            ->select()
            ->get();
            
// Build a new select query in a repository with a limit
$query = $this->queryBuilder->new($this->entityName)
            ->select()
            ->limit(2)
            ->get();
            
// Build a new select query in a repository with a where clause
$query = $this->queryBuilder->new($this->entityName)
            ->select()
            ->where(['age' => 25])
            ->get();
