Creating an ObjectModel for a Module

[mohdoh]

I am creating a new module that create, read, update and delete a table in the database. Thus, I am creating a new ObjectModel for this module. Below is what I did, appreciate if someone can point out what I am doing wrong that the Controller not reading the classl:
 
I created a classes folder in the module directory, and place the following 'Measurement.php' file in it:

<?php
class MeasurmentCore extends ObjectModel
{
	public $id_customer = null;
	public $alias;
	public $weight;
	public $height;
	public $date_add;
	public $date_upd;
	public $deleted = 0;
	public static $definition = array(
		'table' => 'measure',
		'primary' => 'id_measure',
		'fields' => array(
			'id_customer' => 		array('type' => self::TYPE_INT, 'validate' => 'isNullOrUnsignedId', 'copy_post' => false),
			'alias' => 				array('type' => self::TYPE_STRING, 'validate' => 'isGenericName', 'required' => true, 'size' => 32),
			'weight' => 			array('type' => self::TYPE_INT, 'validate' => 'isUnsignedInt', 'required' => true),
			'height' => 			array('type' => self::TYPE_INT, 'validate' => 'isUnsignedInt', 'required' => true),
			'deleted' => 			array('type' => self::TYPE_BOOL, 'validate' => 'isBool', 'copy_post' => false),
			'date_add' => 			array('type' => self::TYPE_DATE, 'validate' => 'isDateFormat', 'copy_post' => false),
			'date_upd' => 			array('type' => self::TYPE_DATE, 'validate' => 'isDateFormat', 'copy_post' => false),
		),
	);
}

Then in the ModuleFrontController 'measurements.php' located in the 'measure/controllers/front/'

<?php
Class MeasureMeasurementsModuleFrontController extends ModuleFrontController
{
	protected $_measure;

	public function init()
	{
		parent::init();

		include_once(_PS_MODULE_DIR_.'measure/classes/measurement.php');
		$this->_measure = new Measurement($id_measure);
		
	}  

	public function initContent()
	{
		parent::initContent();
		$this->setTemplate('measure.tpl');
				
	} 
}

When I load the '/index.php?fc=module&module=measure&controller=measurements' page, I get this error:

Fatal error: Class 'Measurement' not found in C:\wampn\.*.*\modules\measure\Controllers\front\Measurements.php on line 11

Thanks in advance,

Hi

 

i think you miss indicate $id_measure

if i look Addresscontrller.php the $id_adress = somethink

 

try

public function init()
{
parent::init();

include_once(_PS_MODULE_DIR_.'measure/classes/measurement.php');

$id_measure = (int)Tools::getValue('id_measure', 0);

// Initialize measure
if ($id_measure)
{
$this->_measure = new Measurement($id_measure);
}

}  

@++

You "should" use include_once before class definition

<?php
require_once(...);

Class MeasureMeasurementsModuleFrontController extends ModuleFrontController
{

But ... in overall: You should never use require/include methods. Use composer instead of it and you can rely on it's autoloader.

 

Also few more things: follow the rules and standards: PSR-2, SOLID, camel case naming convention, etc.

This is crucial to keep your code clean, extendable and understanable when you will have to work with it later.

composer is something i am working on, i also had some errors using object model, i was looking to rely on direct db requests, i was creating a module for prestashop facebook comments, got some help on object model validation methods from a blog post....

 

what is the issue with require_once....
