Check before checkout

[name29]

Hi!

 

How i can insert before checkout some custom PHP code in order to verify that the product inside the shopping card are really saleble?

 

 

Thank you

edit, or better, override controllers/front/OrderController.php   (Make backup)

 

And in function Init, you could add some code to check. They do already some basic check here, like:

 

 

 

...

$product = $this->context->cart->checkQuantities(true);

 

if ((int)$id_product = $this->context->cart->checkProductsAccess())

{

  $this->step = 0;

  $this->errors[] = sprintf(Tools::displayError('An item in your cart is no longer available (%1s). You cannot proceed with your order.'), Product::getProductName((int)$id_product));

}

 

// If some products have disappear

if (is_array($product))

{

  $this->step = 0;

  $this->errors[] = sprintf(Tools::displayError('An item (%1s) in your cart is no longer available in this quantity. You cannot proceed with your order until the quantity is adjusted.'), $product['name']);

}

 

// Check minimal amount

  $currency = Currency::getCurrency((int)$this->context->cart->id_currency);

...

 

etc.

 

You could then add your own check function here.

 

My 2 cents,

pascal.

Hi Pascal!

 

Thank you for your reply!

 

I need to add some fields during check-out (before payment ) and verify that the service that are insidie the shopping cart are selable.

 

Where i can put the code for add another "step" (login/address/payment) in the check-out process?

Hi name29,

 

in the same file:

/controllers/front/OrderController.php

 

you will see a function:

 

public function initContent()

 

with a switch command, where depending on

     switch ((int)$this->step)

 

it will go to login/address/carrier/billing etc.

 

In theory, you could add a step here, but at least in this file, and maybe outside it, it references many times to step X, step Y

 

like this code:

   if (!$this->context->customer->isLogged(true) && in_array($this->step, array(1, 2, 3)))

 

 

so be very, very careful if you insert a step, that you have to renumber the steps everywhere.

 

my 2 cents,

pascal
