Restricting payment methods to only certain categories

I've had 2 clients request the ability to limit payment methods to only certain categories. For example, one has products that he is not allowed to take payments from paypal but can accept payments thru authorize.net for the same productsl. These products are in one category only.

I would assume that you could add in a switch to the specific payment method itself not to allow for certain categories (haven't considered that thru yet so I could be wrong) but would it be possible to add this as a switch for all payment methods rather than do one at a time?

If you wanted to disable PayPal Express for Products in categories_id 12, where categories_id 12 is the master_categories_id for these Products ... then you can customize the code in RED:
/includes/modules/payment/paypalwpp.php

    $this->enabled = (MODULE_PAYMENT_PAYPALWPP_STATUS == 'True');

// bof: do not show for categories_id 12 based on master_categories_id
    if (!IS_ADMIN_FLAG) {
      global $cart;
      $chk_cat = $_SESSION['cart']->in_cart_check('master_categories_id','12');
      if ($chk_cat > 0) {
        $this->enabled = false;
      }
    }
// eof: do not show for categories_id 12 based on master_categories_id

wow, you must have answered during my server changes. Just saw this - now got to remember who was asking for it!

Thanks once again!

You are most welcome ... :smile:

Hi,
Can i add restrictions for product ID s as well (in addition to blocking categories) 
TIA

Let's say you want to add products_id 33 and another categories_id 45 just to show you how those would work:
$this->enabled = (MODULE_PAYMENT_PAYPALWPP_STATUS == 'True');

[B]// bof: do not show for categories_id 12 and 45 based on master_categories_id and products_id 33
    if (!IS_ADMIN_FLAG) {
      global $cart;
      $chk_cat = $_SESSION['cart']->in_cart_check('master_categories_id','12');
      $chk_cat += $_SESSION['cart']->in_cart_check('master_categories_id','45');
      $chk_cat += $_SESSION['cart']->in_cart_check('products_id','33');
      if ($chk_cat > 0) {
        $this->enabled = false;
      }
    }
// eof: do not show for categories_id 12 and 45 based on master_categories_id and products_id 33
[/B]

the += keeps adding on to the count for $chk_cat for each categories_id where master_categories_id matches and for specific products_id where the products_id matches ...

The $_SESSION['cart']->in_cart_check can check cart content based on many things, and only on occasion is there any reason to touch the actual shopping_cart.php class file to obtain matches for various types of checks regarding what is in the shopping_cart ...

Thanks so much!
