Adding an additionnal input to an order


Recommended Posts

 Hi ! 


So what I want to do seems quite simple : allowing the customers to choose a precise hour of delivery for their order (to be displayed in the back-office).


I did some research and this is what I did so far :


    - Added "myVariable" to ps_cart table.

    - Added public $myVariable in Cart.php

    - Added 'myVariable' => array('type' => self::TYPE_DATE) in $definition in Cart.php

    - Created a module :

if (!defined('_PS_VERSION_'))
class heureLivraison extends Module
	public function __construct()
		$this->name = 'heurelivraison';
		$this->tab = 'front_office_features';
		$this->version = '1.0';
		$this->author = 'COLIN Théotime';
		$this->need_instance = 0;
		$this->ps_versions_compliancy = array('min' => '1.5', 'max' => '1.6');
		$this->bootstrap = true;
		$this->displayName = $this->l('Heure livraison');
		$this->description = $this->l('Permet aux clients de choisir une heure de livraison précise.');
		$this->confirmUninstall = $this->l('Are you sure you want to uninstall?');
		if (!Configuration::get('HEURELIVRAISON_NAME'))      
		  $this->warning = $this->l('No name provided');
	public function install()
		if (!parent::install())
		return false;
		return true;
	public function uninstall()
		if (!parent::uninstall())
		return false;
		return true;
	public function hookActionCarrierProcess($params)
		$cart = $params['cart'];
		$cart->myVariable = Tools::getValue('myVariable'); 

   - Installed it and hooked it to ActionCarrierProcess.

   - Added an input on the check out page.


Though, the variable isn't added to the table. I think my module isn't working as even with a fixed date, nothing is added.


Thanks for help ! May give away a little reward (Amazon gift card or anything else) if anyone can help me figure this out.

I expect the cart isn't saved during the checkout process anymore.


Maybe add the variable/field to the Order class/table, instead of the cart. Then when the order is saved (when confirming the order), it should be saved automatically.


My 2 cents,

Hmmm, so basically in which file do I need to get the value and add it to $order ? (using Tools::getValue('myVariable'); I guess ?)

I'm sorry, I'm really new to this but I'm slowly beginning to understand !


Thanks a lot for the answer.

Hi Nerloggz,


You should at first have a look at the Prestashop developer documentation  :


Your module should consist of some of these :

1- a form : /themes/Mytheme/appli.tpl

2- optional Css or Js files : /themes/Mytheme/css or /themes/Mytheme/js or /themes/Mytheme/modules/XXX/css or /themes/Mytheme/modules/XXX/js

3- controller or override files :

        - front : /controllers/front/AppliController.php

        - admin :  /controllers/admin/AdminAppliController.php  (for the backoffice management)

4- classes : /classes/Db.php contains some variables and the definition (fields) of the database table.

5- Database : using sql command or phpmyadmin, you have to prealably update your database, insert all new fields


Hope this help.
