COD only above certain order amount?

[ronwong]

Hi, this does not work either

------------------------
// turn off COD for low value
if (zen_get_shipping_enabled($this->code) and $total_cart >= 50) {
$this->enabled = ((MODULE_PAYMENT_COD_STATUS == 'True') ? true : false);
}
-----------------------

I'd have to actually see the page of code you are trying to alter to tell you where to place it and to find out if that code is the exact code you need.

It is the "style" you want to follow though. I used it on a few sites (for shipping etc..) and it worked fine. Again, though, those are different modules.

[ronwong]

The following is the standard cod.php file that came with the installation,

'// turn off COD for table' and '// turn off COD for low value' is what I tried to add, both does not work

I really appreciate your help...

You want it to look like this. As I mentioned in the previous post, the information I sent you was for example only to get you moving in the right direction. You had the wrong variable and did not specify the order total to run your figures against on the page.

You must either be doing something wrong, a setting somewhere in the cart is incorrect, or the session variable is not pulling correctly.

I have that exact code working (for $50 and over to get COD otherwise they do not get that option) on my zen test site without a hitch:



EDIT:

In fact, after I just submitted this post I saw your mistake so I am editing it here.

You have the following code:
$this->enabled = ((MODULE_PAYMENT_COD_STATUS == 'True') ? true : false);
(the above line should NOT be in here).

//$this->enabled = ((MODULE_PAYMENT_COD_STATUS == 'True') ? true : false);
$total_cart = $_SESSION['cart']->show_total();
if ($total_cart >= 50) {
$this->enabled = ((MODULE_PAYMENT_COD_STATUS == 'True') ? true : false);
}

That is incorrect.

You left in the bold variable I show above and in fact, if you look at the code I sent, or copied directly, you'll see I commented that line out with a "//" in front.

You need to remove that line in bold above and it should work just fine.

[ronwong]

good grief! You are absolute right! I got it working!

This is a first step. I am actually looking for a more complex setup, I will be trying to play with the codes before I ask for your kind help:

This is the pseudo code:

COD availbale if:
delivery is 'self collect' (all case)
else
availbale if order above $50 only for other delivery methods


---------------------------------------------
My settings"
-Shipping available: Local Van delivery($10), Post(pay stamp), Self collect(free), Free Shipping(free)
-PAyment: Credit card, COD, Check.MO, Bank Transfer
-Free delivery if total order > $30
-Free deliver if chosen leave the option with us to send down by post or van.

I want to limit COD option to orders above $50 because COD obviously means we have to send van down for delivery, so we want to discourange that for small orders ($30-50).

I have done this with your code!

But If people choose self collect, they should have the option to COD even if its $5 total order. Currently these group will not have COD option with this new code.

I am running this site in Singapore, which is a damn small place, so we have local delivery as a very big part of consideration, and COD too.

[ronwong]

Hi Linda, your code has problem as well, with a clean cod.php file and your additional codes, its ok on the customer side checkout. It is also ok in admin when I click modules-payment. But when I open the admin-customers-orders, and click to open each order, orders with COD as payment will not open, and there is a line:

PHP Fatal error: Call to a member function on a non-object in C:\Program Files\Ensim\Sitedata\onlineshop\Inetpub\wwwroot\includes\modules\payment\cod.php on line 74

line 74 refers to this line:

if ($_SESSION['cart']->show_total() < 50) {

I have taken out all other codes regarding the other conditions. so its down to the baisc total>50 codes only.

Any idea?

[Ajeh]

Where exactly are you when you see this error?

I am trying to reproduce it ...

[ronwong]

hi,
ok, clean unmodified file, then put in your code in cod.php, no other conditions yet. So orders above 50, COD will show, below, COD will not show. I log in as a regular registered customer and tried all the combination of shipping and payment. Works fine.

Now I log into admin.
Modules -> Payment. No error. Your code solved the problem over econcepts original code. Great.

Now the error:
Do a check out transaction with a dummy customer. You can try 2 transaction to compare. One use COD, another use say bank transfer. Both have to be above $50 so that COD is shown?

Log back into admin.
Customers -> Orders
So your new 2 transaction is listed. say 1001 and 1002.
We usually click on the transaction to open it up to see the details, and also to update status etc.
But if the transaction is a COD transaction, it wont show the details, it will show:

PHP Fatal error: Call to a member function on a non-object in C:\Program Files\Ensim\Sitedata\onlineshop\Inetpub\wwwroot\in cludes\modules\payment\cod.php on line 74

and nothing else. I dont believe I did any other customization of any sort.
