link payment product price to item price

[jw4]

I want to link the payment product price to the price of the item being advertised.

I have 2 payment products:
item under �10 - free (product id '1')
item over �10 is 10% item value to max �5.00. (product id '16')

In includes/core/checkout/step3submit I have amended the code to be conditional update of oSubTotal as follows (added code in red, existing in blue) under the create order section (at line 134)

// adding condition statement to set ad price to % of total price for general item ads JM 10.11.10
if ($orderdata['oProductID']='16')
{
if ($data['price']>='50') {
$orderdata['oSubTotal']='5';
}
else
{
$orderdata['oSubTotal']=$data['price']/10;
}
}
else
{
$orderdata['oSubTotal']=$subTotal;
}
//end of added code

What is happening though is that if free ad package selected (productid 1), price at Listing preview is calculated as for productid 2.

Somehow the field I am checking 'oProductID' gets set to '16' no matter which payment product selected.

I have checked in debug as follows (where product id is 1 - i.e. free ad):

Listing details: $productid=1

Add Images: $pID=1

Step 5: Verify detaisl - $productid-1 BUT $oProductID=16 (where does this come from?)

Listing Preview: both $productid and $oProductId now = 16

PLEASE can anyone tell me what I am doing wrong? I don't understand why my if statement is not working on the product id and why the product id values are changing in the later scripts.

Any help gratefully received!

I don't know how that is happening, however one thing I would recommend to you is NOT use the variable $orderdata['oProductID']

Everything throughout the checkout process regarding the product is by the variable $productid, which includes assigning $orderdata['oProductID'] = $productid which is right above where I am assuming you put the code that you posted. The $orderdata array is used only to update the order in the db and nowhere else.

Try basing your logic on the variable $productid instead

PHP Code:

if ( $productid = 16 )

HI thanks very much for response.

I have tried using $productid instead, but it doesn't work. Even though in debug mode I can see $productid is available, when hitting continue after entering listing details I get the following error message:

Warning: Smarty error: unable to read resource: "" in /home/corpora7/public_html/our-stuff.org/includes/classes/smarty/Smarty.class.php on line 1092.

Could you tell me what I am doing wrong?

Here is the amended code

// adding condition statement to set ad price to % of total price for general item ads JM 10.11.10
if ($productid=16)
{
if ($data['price']>='50')
{
$orderdata['oSubTotal']='5';
}
else
{
$orderdata['oSubTotal']=$data['price']/10;
}
}
else
{
$orderdata['oSubTotal']=$subTotal;
}
//end of added code


Many thanks again for any help.

Just to let you know, my problem resolved using $productid (for id value '1').

I don't know what the problem was - maybe some data corruption. I deleted and re-added the payment products and deleted all history from my browsers.

I know have a payment product where the Ad price relates to the cost of the item being sold, to a maximum value of �5.00 - condition coded as:

//adding condition statement to set ad price to % of total price for general item ads JM 10.11.10

if ($productid=1)
{

if ($data['price']>='50')
{
$orderdata['oSubTotal']='5';
}

if ($data['price']>'10' && $data['price']<'50')
{
$orderdata['oSubTotal']=$data['price']/10;
}
}
//end of added code

thanks again for help, this is a great forum
