Override feature.php

[Algirdas]

Hello,

 

I'm trying to override faeture.php class and  add custom field to it. I found tutorial how to add custom field to product class, but difference is that feature class don't have __constructor method and I don't know how to add custom field.
Maybe someone could give me example how to do that?

Also, when prestashop updates mysql database by overrided class?

 

Thank you

The simplest example for your override:

/*
Place this in /override/classes/Feature.php
*/
Feature::$definition['fields']['custom'] = array('type' => ObjectModelCore::TYPE_STRING, 'size' => 100);

class Feature extends FeatureCore
{
	public $custom;
}

Similar, for a feature value, which depends on different languages, you can see bellow:

/*
Place this in /override/classes/FeatureValue.php
*/
FeatureValue::$definition['fields']['custom'] = array('type' => ObjectModelCore::TYPE_STRING, 'lang' = true, 'size' => 100);

class FeatureValue extends FeatureValueCore
{
	public $custom;
}

Don't forget to delete /cache/class_index.php file for changes to take effect.
