Postage rates by Attribute

[bargaindropper]

OK, here is the thing:

Due to Royal Mail having pricing by proportion, my problem is that many items can be posted by Large Letter. If I have an attribute, I need to change it to Packet rate.
I currently do this with some products by using products_type.

The query is currently:

      if ((IS_ADMIN_FLAG == false && $_SESSION['cart']->in_cart_check('products_options_value_id','2') > 0)) {
          $this->enabled = false;
      } 
 
 {
          // Enable option otherwise
          $this->enabled = true;

Is it possible to do something similar based on attributes.

I need to check for options_values_id in products_attributes to see if it is 74 or 75, so I can disable the large letter rate. (which is what the code above is taken from.

Many thanks.

Whoops, I messed that up. I copied the code, I had tried tweaking.

if ((IS_ADMIN_FLAG == false && $_SESSION['cart']->in_cart_check('products_type','2') > 0)) {
$this->enabled = false;
}

{
// Enable option otherwise
$this->enabled = true;

Think I posted this in the wrong section.

Anyway, I have figured out a solution which appears to work.

In the relevant postage section (rm2ndlargeletter.php) I added the following lines:

	Just after the global $order, $total_weight ;
$query = 'SELECT products_options_value_id FROM customers_basket_attributes WHERE products_options_value_id >= 74';
	$this->prod_attrib = mysql_query($query);

and further down after } // end of looping through

if ((IS_ADMIN_FLAG == false && $_SESSION['cart']->in_cart_check('products_type','2') > 0))
		{
		$this->enabled = false;
		return ;
		}

	elseif(mysql_num_rows($this->prod_attrib)!=0){
		
		$this->enabled = false;
		}else{
          // Enable option otherwise
		$this->enabled = true;
		}		  
		return ;

That takes into account the product type of 2, then does a query on the basket to see if there are any items with the attributes of >73 which for me means gift boxes. If so, de-activates this shipping method.
The same code needs inserting into the rm2ndpacket.php but changing the false to true and the true to false.

Similare is done for signed for and 1st class.

Maybe not the best way to do it but then, I am no PHP programmer :).

Thought I would share that incase anyone could use it or improve on it.
