README

What's the QueryModel ?

Abstract: QueryModel is a standalone component for inserting, updating, reading and deleting data in the database. Recommended for projects with mvc structure.

Getting Started

Installation

You can install the QueryModel in your project with composer.

Just run the command below on your terminal:

composer require basecode/querymodel

or in your composer.json require:

"basecode/querymodel": "1.1.*"

Usage

For the correct functioning of the QueryModel it is necessary that you create a constant named DB_CONFIG with the access data of the database. See the example below.

Example config.php file:

<?php
define("DB_CONFIG", [
    "driver" => "mysql",
    "host" => "localhost",
    "name" => "querymodel",
    "user" => "root",
    "password" => "",
    "options" => [
        PDO::MYSQL_ATTR_INIT_COMMAND => "SET NAMES utf8",
        PDO::ATTR_DEFAULT_FETCH_MODE => PDO::FETCH_OBJ
    ]
]);

Example of use index.php file:

<?php
    date_default_timezone_set("America/Sao_Paulo");

    define("DS", DIRECTORY_SEPARATOR);
    require_once dirname(__DIR__).DS."vendor".DS."autoload.php";
    require_once dirname(__FILE__).DS."config".DS."Config.php";

    use BaseCode\QueryModel\QueryModel;

    Class User extends QueryModel
    {
        protected $table = "users";
        // protected $primary = "id";

        protected $required = [
            "name",
            "email",
            "password"
        ];

        protected $timestamp = [
            "create" => "created_at",
            "update" => "updated_at"
        ];

        public function posts()
        {
            return $this->select("users.name, posts.title")
            ->join("INNER JOIN posts ON users.id = posts.id_user")
            ->where("users.id = :id")
            ->params(["id" => $this->id])
            ->execute();
        }

        public function usersPosts()
        {
            return $this->select("users.id, users.name, posts.title")
            ->join("INNER JOIN posts ON users.id = posts.id_user")
            ->execute();
        }

    }

    Class Post extends QueryModel
    {
        protected $table = "posts";
        // protected $primary = "id";

        protected $required = [
            "id_user",
            "title",
            "message"
        ];

        protected $timestamp = [
            "create" => "created_at",
            "update" => "updated_at"
        ];

    }

    $user = new User();
    $post = new Post();

    echo "<pre>";

    // insert register
    $user->name = "test";
    $user->email = "[e-mail]";
    $user->password = md5("123");
    $user->save();
    
    // select all
    print_r($user->all()->execute());

    // select all set columns
    print_r($user->select("name, email")->all()->execute());

    // select all set limit
    print_r($user->all()->limit(1)->execute());

    // select all set order by
    print_r($user->all()->orderBy("id DESC")->execute());

    // select all return first
    print_r($user->all()->first());

    // select by id and fill in the model
    $user->findById(2)->fill();
    print_r($user);

    // select by id and return object stdClass with the data
    print_r($user->findById(2)->first());

    // select by id and update
    $user->findById(1)->fill();
    $user->email = "[e-mail]";
    $user->save();

    // select by condition without parameters | not recommended
    $result = $user->findBy("email = '[e-mail]'")->execute();
    print_r($result);

    // select by condition with parameters | recommended
    $result = $user->findBy("email = :email")->params([
        "email" => "[e-mail]"
    ])->execute();
    print_r($result);

    // destroy user current
    $user->findById(4)->fill();
    $user->destroy();

    // delete by condition without parameters | not recommended
    $user->delete("email = '[e-mail]'");

    // delete by condition with parameters | recommended
    $user->delete("email = :email", [
        "email" => "[e-mail]"
    ]);

    // mode of use select joins (INNER JOIN, LEFT JOIN, RIGHT JOIN...)
    $user->findById(9)->fill();

    // erros
