Add Html tags in Product Feature - html

Question

I need to save html tags in features section of the create/edit product page.
I have changed TYPE_HTML and isCleanHTML in classes/FeatureValue.php, but the validation still ignores html tags.
Ex.
'value' => array('type' => self::TYPE_HTML, 'lang' => true, 'validate' => 'isCleanHtml', 'required' => true, 'size' => 255),
Thank you.

You have to use definition of FeatureValue and change it so it can save HTML as well as need to change code in file where it is saving product custom feature value. Rather than changing in core files, I will make use of Overrides.
Follow below mentioned steps.
1) Create file Product.php file on path override\classes and put below code in it. This will save HTML in value field.
<?php
/**
* #override Product.php
*/
class Product extends ProductCore
{
/**
* Add new feature to product
*/
public function addFeaturesCustomToDB($id_value, $lang, $cust)
{
$row = array('id_feature_value' => (int)$id_value, 'id_lang' => (int)$lang, 'value' => pSQL($cust, true));
return Db::getInstance()->insert('feature_value_lang', $row);
}
}
2) Create FeatureValue.php file on path override\classes and put below code in it. Changing definition so that it can validate HTML.
<?php
/**
* #override FeatureValue.php
*/
class FeatureValue extends FeatureValueCore
{
/**
* #see ObjectModel::$definition
*/
public static $definition = array(
'table' => 'feature_value',
'primary' => 'id_feature_value',
'multilang' => true,
'fields' => array(
'id_feature' => array('type' => self::TYPE_INT, 'validate' => 'isUnsignedId', 'required' => true),
'custom' => array('type' => self::TYPE_BOOL, 'validate' => 'isBool'),
/* Lang fields */
'value' => array('type' => self::TYPE_HTML, 'lang' => true, 'validate' => 'isCleanHtml', 'required' => true, 'size' => 255),
),
);
}
3) To autoload newly created override class files; delete class_index.php file from var\cache\dev and var\cache\prod folder.
Hope it will help you!
