The data layer is a persistent abstraction component of your database that PDO has prepared instructions for performing common routines such as registering, reading, editing, and removing data.

O data layer é um componente para abstração de persistência no seu banco de dados que usa PDO com prepared statements para executar rotinas comuns como cadastrar, ler, editar e remover dados.

Documentation

For details on how to use the Data Layer, see the sample folder with details in the component directory

connection

To begin using the Data Layer, you need to connect to the database (MariaDB / MySql). For more connections PDO connections manual on PHP.net

Para começar a usar o Data Layer precisamos de uma conexão com o seu banco de dados. Para ver as conexões possíveis acesse o manual de conexões do PDO em PHP.net

define("DATA_LAYER_CONFIG", [
    "driver" => "mysql",
    "host" => "localhost",
    "port" => "3306",
    "dbname" => "datalayer_example",
    "username" => "root",
    "passwd" => "",
    "options" => [
        PDO::MYSQL_ATTR_INIT_COMMAND => "SET NAMES utf8",
        PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION,
        PDO::ATTR_DEFAULT_FETCH_MODE => PDO::FETCH_OBJ,
        PDO::ATTR_CASE => PDO::CASE_NATURAL
    ]
]);

your model

The Data Layer is based on an MVC structure with the Layer Super Type and Active Record design patterns. Soon to consume it is necessary to create the model of your table and inherit the Data Layer.

O Data Layer é baseado em uma estrutura MVC com os padrões de projeto Layer Super Type e Active Record. Logo para consumir é necessário criar o modelo de sua tabela e herdar o Data Layer.

class User extends DataLayer
{
    /**
     * User constructor.
     */
    public function __construct()
    {
        //string "TABLE_NAME", array ["REQUIRED_FIELD_1", "REQUIRED_FIELD_2"], string "PRIMARY_KEY", bool "TIMESTAMPS"
        parent::__construct("users", ["first_name", "last_name"]);
    }
}

find

<?php
use Example\Models\User;
$model = new User();

//find all users
$users = $model->find()->fetch(true);

//find all users limit 2
$users = $model->find()->limit(2)->fetch(true);

//find all users limit 2 offset 2
$users = $model->find()->limit(2)->offset(2)->fetch(true);

//find all users limit 2 offset 2 order by field ASC
$users = $model->find()->limit(2)->offset(2)->order("first_name ASC")->fetch(true);

//looping users
foreach ($users as $user) {
    echo $user->first_name;
}

//find one user by condition
$user = $model->find("first_name = :name", "name=Robson")->fetch();
echo $user->first_name;

//find one user by two conditions
$user = $model->find("first_name = :name AND last_name = :last", "name=Robson&last=Leite")->fetch();
echo $user->first_name . " " . $user->first_last;

findById

<?php
use Example\Models\User;

$model = new User();
$user = $model->findById(2);
echo $user->first_name;

secure params

See example find_example.php and model classes

Consulte exemplo find_example.php e classes modelo

$params = http_build_query(["name" => "UpInside & Associated"]);
$company = (new Company())->find("name = :name", $params);
var_dump($company, $company->fetch());

join method

See example find_example.php and model classes

Consulte exemplo find_example.php e classes modelo

$addresses = new Address();
$address = $addresses->findById(22);
//get user data to this->user->[all data]
$address->user();
var_dump($address);

count

<?php
use Example\Models\User;
$model = new User();

$count = $model->find()->count();

save create

<?php
use Example\Models\User;
$user = new User();

$user->first_name = "Robson";
$user->last_name = "Leite";
$userId = $user->save();

save update

<?php
use Example\Models\User;
$user = (new User())->findById(2);

$user->first_name = "Robson";
$userId = $user->save();

destroy

<?php
use Example\Models\User;
$user = (new User())->findById(2);

$user->destroy();

fail

<?php
use Example\Models\User;
$user = (new User())->findById(2);

if($user->fail()){
    echo $user->fail()->getMessage();
}

custom data method

class User{
    //...

    public function fullName(): string 
    {
        return "{$this->first_name} {$this->last_name}";
    }
    
    public function document(): string
    {
        return "Restrict";
    }
}

echo $this->full_name; //Robson V. Leite
echo $this->document; //Restrict
