[firefoxrembi]

Hi,

I want add new field in prestashop 1.5 on information tab when I add or edit product. This field only insert a bit value to database like online_only field or sale.

 

I add checkbox in information.tpl file and add in product.php file this line

/** @var boolean hit */
   public $hit = false;

 

and in same file

 

'hit' =>						 array('type' => self::TYPE_BOOL, 'shop' => true, 'validate' => 'isBool'),

but when I add last code, the value is inserted but no insert product name and other field.
