ObjectModel

PHP helpers to access objects and its collections in database

Warning! This project is currently in deep private beta. Please do not use it if you care about anything good.

Installation

  1. Add this package as a Composer dependency:
composer require getrix/objectmodel
  1. Define a database callback. This is a callback function stored in a static property $databaseCallback of ObjectModel class that should return an PDO object with link to database.

 

Usage

Quick example:

use Getrix\ObjectModel;

Getrix\ObjectModel::setDB(
    new PDO("mysql:dbname=bbass;host=localhost", "user", "password"
);

final class Post extends Getrix\ObjectModel {
  protected static $table = 'Posts';
  protected static $primaryKey = 'id';

  public function __construct(array $row = null) {
    parent::__construct(self::$table, self::$primaryKey,
      [
        "id" => [
          "type" => "integer"
        ],
        "title" => [
          "type" => "string"
        ],
        "text" => [
          "type" => "string"
        ]
      ], $row );
  }
}

$post = Post::getById(1);

var_dump($post);

Field rules

Any object handled with ObjectModel should have a schema that describes validation and transformation rules for each of data field in database. Schema should be defined in object constructor, for ex.:

[
    "id" => [
      "type" => "integer"
    ],
    "title" => [
      "type" => "string"
    ],
    "text" => [
      "type" => "string"
    ]
]

 

Schema field properties

Property Description Values Default
type Type of field See “Schema field types” below string
required Is this field is required or not true or false false
default Default value for the field that will be set in case of field value is null any -
fn Field validator/transformation callback function. Will be used instead of default type validation rules function(ObjectField $schema,mixed $value,boolean $reverse) -
populate Used to define population class name See “Populating field values” below -

 

Schema field types

Type Description Direct action (from DB) Reverse action (to DB)
string Plain string Applies stripslashes default PHP function after the htmlspecialchars_decode Applies addslashes after htmlspecialchars
integer Number
associative Associative array Translates stored value to corresponding value in values field property by its key Stores key value of corresponding entry in values associative array of the field
