Enable PayPal but Only when Product ID 1234 is in cart?

[Ajeh]

See post #15 for how to do this ...

If you're still watching this Ajeh, I have a quick question for you.

This works a treat when I just want PayPal to show when only product ID 1395 is in the cart and nothing else:

if (!IS_ADMIN_FLAG) {
  // disable, (even when admin has it switched on):
  $this->enabled = false;
  global $cart;
  if ($_SESSION['cart']->in_cart_check('products_id','1395') > 0 && $_SESSION['cart']->count_contents() == $_SESSION['cart']->in_cart_check('products_id','1395')) {
    $this->enabled = true;
  }
} 

How would I tweak this code so that PayPal becomes an option when product ID 1395 is in the cart and any other product is also in the cart alongside it?

This part, when added in conjunction with the first half of the conditions, forces that the ONLY thing in the cart is that product number; so remove it if you don't care what else is in the cart with it:

&& $_SESSION['cart']->count_contents() == $_SESSION['cart']->in_cart_check('products_id','1395')

I think I may have figured it out. I just changed this:

  if ($_SESSION['cart']->in_cart_check('products_id','1395') > 0 && $_SESSION['cart']->count_contents() == $_SESSION['cart']->in_cart_check('products_id','1395')) { 

To this:

  if ($_SESSION['cart']->in_cart_check('products_id','1395') > 0 ) {

I'd like to take this in a slightly different direction by changing the logic to a customer ID instead of a product ID. What would I need to change this to?

if ($_SESSION['cart']->in_cart_check('products_id','6251') > 0 ) {

The logged-in customer number is in $_SESSION['customer_id']. Check against that.

Thank you Dr. Byte. I'm afraid the syntax and the general terms just let me down every time. I've no idea how to write it. This would probably just white screen the site:

if ($_SESSION['cart']->in_cart_check('customer_id','') = 4959 ) {


What do you change 'cart' to and what do you change ->in_cart_check to and I'm guessing the ('customer_id','') = 4959 is probably wrong too? I don't know how you gurus just know all that stuff :)

Forget any of the previous code posted. Instead, please write in english the logic you want turned into code. What do you want to do and why?

[limelites]

If user ID (or is it customer ID) is logged into her account then enable the PayPal payment module for her. Her customer ID is 4959

We don't like to take PayPal but on special request we will take it. So, if a customer asks us to take PayPal then it's good to be able to switch it on for them only.

Then change this (from your previous post awhile back):

 if ($_SESSION['cart']->in_cart_check('products_id','1395') > 0 ) {  

to this:

   if ($_SESSION['cart']->in_cart_check('products_id','1395') > 0  || $_SESSION['customer_id'] == 4959) {
