$this->enabled = ((MODULE NAME HERE == 'True') ? true : false);

  $this->enabled = false;

Hello,
Can anyone help with the above please...
Credit card fraud is currently rife in Japan, we have reported 5 people to the police here, who basically tell you if we do anything or not, we will not let you know, and you can not follow up.

Considering we dont even get an incident number or similar, Im pretty sure all their notes, just go through the shredder as soon as we leave, despite them saying yes this is absolutely fraud.

Im trying to disable a credit card module if its the customers first order, and found the above on the forum which will disable the order if its over a certain value.
Can anyone please help with the query to find out if its the customers first order...
More specficically this line ->show_total() >= 5000)

Thanks in advance.

you could try something like:

// from
$this->enabled = ((MODULE NAME HERE == 'True') ? true : false);

global $cart;
if (!IS_ADMIN_FLAG && $_SESSION['cart']->show_total() >= 5000) {
  $this->enabled = false;
}
//to:
$this->enabled = ((MODULE NAME HERE == 'True') ? true : false);

global $cart, $db;
$customers_orders = $db->Execute("SELECT orders_id 
                                                  FROM " . TABLE_ORDERS . " 
                                                  WHERE customers_id = " . (int)$_SESSION['customer_id']);

if (!IS_ADMIN_FLAG && $customers_orders->EOF) {
  $this->enabled = false;
}

If using any production release to date of zen Cart 1.5.x (version was not stated in this thread) then could use the built in function: zen_count_customer_orders to check on the number of orders the customer has had.

The function has been found in includes/functions/functions_customers.php

The call could be:
zen_count_customer_orders($_SESSION['customer_id'])

And could look like the below using the above code from the OP:

$this->enabled = ((MODULE NAME HERE == 'True') ? true : false);

// global $cart; // <--- the code to the left is not necessary for this portion of the code, can't speak for below all of this. 
if (!IS_ADMIN_FLAG && zen_count_customer_orders($_SESSION['customer_id'] ?? 0) > 0) {
  $this->enabled = false;
}

While I don't really see a specific need to have the fallback to 0 if the customer_id is not set, I included it for those situations where something else has been modified away from default expected code.

Excellent, thanks very much will give it a go :)

Another way to go would be the Optional Payment Method plugin:
