Hi @caesar cek Support page please

has been submit new ticket

Hi, I'm sorry for bumping this old issue. The code above works fine for me. However, this become problem when I want only selected payment method to implement this. I.e, keep paypal payment as is, where offline payment, using fraction.

What I need is a code to detect payment method for current invoice.
Would you like to help me achieve that?

@caesar not work , could you help me please to full code?

Code:

 Am_Di::getInstance()->hook->add(Am_Event::INVOICE_CALCULATE, function(Am_Event $e) {
if ($invoice->paysys_id == 'offline') {
   if (@$GLOBALS['add_fraction']++) return;

   $invoice = $e->getInvoice();
   $item = $invoice->getItem(0);
   $id = $invoice->pk() ?: $e->getDi()->db->selectCell("SELECT MAX(invoice_id)+1 FROM ?_invoice;");
   if ($item && !$item->data()->get('add_fraction')) {
       $item->data()->set('add_fraction', 1);
       $item->data()->set('orig_first_price', $item->data()->get('orig_first_price') + ($id % 100));
       $invoice->calculate();
   }
}else{
if (@$GLOBALS['add_fraction']++) return;

   $invoice = $e->getInvoice();
   $item = $invoice->getItem(0);
   $id = $invoice->pk() ?: $e->getDi()->db->selectCell("SELECT MAX(invoice_id)-1 FROM ?_invoice;");
   if ($item && !$item->data()->get('add_fraction')) {
       $item->data()->set('add_fraction', 1);
       $item->data()->set('orig_first_price', $item->data()->get('orig_first_price') - ($id % 100));
       $invoice->calculate();
   }
}
   unset($GLOBALS['add_fraction']);
}); 

@caesar when there is an offline sign up or not it always falls to else. so when there is a signup using offline payment it doesn't work ,no error messages or error codes.

and for example I want to use if else if using currency USD and IDR is also not working.For example, I add a unique number after a (,) or (.), for example like above but behind a (,) or (.) : $10.01 or $10.02. like this . for code I use this code

PHP:

Am_Di::getInstance()->hook->add(Am_Event::INVOICE_CALCULATE, function(Am_Event $e) {
    if (@$GLOBALS['add_fraction']++) return;
    $invoice = $e->getInvoice();
   $item = $invoice->getItem(0);
   $id = $invoice->pk() ?: $e->getDi()->db->selectCell("SELECT MAX(invoice_id)-1 FROM ?_invoice;");
   $es = $invoice->pk() ?: $e->getDi()->db->selectCell("SELECT MAX(invoice_id)+1 FROM ?_invoice;");

    if ($invoice->currency=='USD') {
   if ($item && $item->first_price > 0 && !$item->data()->get('add_fraction'))  {
              $item->data()->set('add_fraction', 1);
       $item->data()->set('orig_first_price', $item->data()->get('orig_first_price') + '0.'.($es % 100));
       $invoice->calculate();  

  }
    } elseif ($invoice->currency=='IDR'){

  
    if ($item && $item->first_price > 0 && !$item->data()->get('add_fraction'))  {
              $item->data()->set('add_fraction', 1);
       $item->data()->set('orig_first_price', $item->data()->get('orig_first_price') - ($id % 100));
       $invoice->calculate();
  }
    }
   unset($GLOBALS['add_fraction']);
});
