"copy_post" meaning?

[Rubens Cury]

Hi all,
 
Does anybody know what means the "copy_post" var used on a class fields definition?
 
Example:

public static $definition = array(
		'table' => 'customer',
		'primary' => 'id_customer',
		'fields' => array(
			'secure_key' => array('type' => self::TYPE_STRING, 'validate' => 'isMd5', 'copy_post' => false),
			'lastname' => array('type' => self::TYPE_STRING, 'validate' => 'isName', 'required' => true, 'size' => 32),
			'firstname' => 	array('type' => self::TYPE_STRING, 'validate' => 'isName', 'required' => true, 'size' => 32),
			'email' => array('type' => self::TYPE_STRING, 'validate' => 'isEmail', 'required' => true, 'size' => 128),
			'passwd' => array('type' => self::TYPE_STRING, 'validate' => 'isPasswd', 'required' => true, 'size' => 32),
			'last_passwd_gen' => array('type' => self::TYPE_STRING, 'copy_post' => false),
			'id_gender' => array('type' => self::TYPE_INT, 'validate' => 'isUnsignedId'),
			'birthday' => array('type' => self::TYPE_DATE, 'validate' => 'isBirthDate'),
			'newsletter' => array('type' => self::TYPE_BOOL, 'validate' => 'isBool'),
			'newsletter_date_add' =>array('type' => self::TYPE_DATE,'copy_post' => false),
			'ip_registration_newsletter' =>	array('type' => self::TYPE_STRING, 'copy_post' => false),
			'optin' => array('type' => self::TYPE_BOOL, 'validate' => 'isBool'),
			'website' =>array('type' => self::TYPE_STRING, 'validate' => 'isUrl'),
			'company' =>array('type' => self::TYPE_STRING, 'validate' => 'isGenericName'),
			'siret' =>array('type' => self::TYPE_STRING, 'validate' => 'isSiret'),
			'ape' =>array('type' => self::TYPE_STRING, 'validate' => 'isApe'),
			'outstanding_allow_amount' =>array('type' => self::TYPE_FLOAT, 'validate' => 'isFloat', 'copy_post' => false),
			'show_public_prices' =>array('type' => self::TYPE_BOOL, 'validate' => 'isBool', 'copy_post' => false),

			'max_payment_days' =>array('type' => self::TYPE_INT, 'validate' => 'isUnsignedInt', 'copy_post' => false),
			'active' =>array('type' => self::TYPE_BOOL, 'validate' => 'isBool', 'copy_post' => false),
			'deleted' =>array('type' => self::TYPE_BOOL, 'validate' => 'isBool', 'copy_post' => false),
			'note' =>array('type' => self::TYPE_HTML, 'validate' => 'isCleanHtml', 'size' => 65000, 'copy_post' => false),
			'is_guest' =>array('type' => self::TYPE_BOOL, 'validate' => 'isBool', 'copy_post' => false),
			'id_shop' => array('type' => self::TYPE_INT, 'validate' => 'isUnsignedId', 'copy_post' => false),
			'id_shop_group' => array('type' => self::TYPE_INT, 'validate' => 'isUnsignedId', 'copy_post' => false),
			'id_default_group' => array('type' => self::TYPE_INT, 'copy_post' => false),
			'id_lang' => array('type' => self::TYPE_INT, 'validate' => 'isUnsignedId', 'copy_post' => false),
			'date_add' =>array('type' => self::TYPE_DATE, 'validate' => 'isDate', 'copy_post' => false),
			'date_upd' => array('type' => self::TYPE_DATE, 'validate' => 'isDate', 'copy_post' => false),

	);

When the customer submits data from the browser (a customer, an address, etc...), only the fields that have copy_post = true are submitted. 

 

The fields that are copy_post = false are never submitted from what the customer, instead they are calculated fields.

 

For example...

The customer name, email address, password would all be copy_post = true, since you want to use the values from the customer.

Other fields like secure_key, last_passwd_gen, newsletter_date_add are copy_post = false, since the customer would never be providing this information, it is also calculated by Prestashop code

Thank you very much @bellini13 for your clear explanation.
