=============================================
This modification will allow you to set percentages in the Table Rate Shipping method.
ie 5.00:3.00,25:10%,500:25999999:3%
Note: DO NOT USE "," ON ANY AMOUNT YOU ENTER, OTHER WISE THE PERCENT WILL NOT WORK FOR YOU.
The location of the edit is
/catalog/includes/modules/shipping/table.php
Around Line 64 After
$table_cost = split("[:,]" , MODULE_SHIPPING_TABLE_COST);
$size = sizeof($table_cost);
for ($i=0, $n=$size; $i<$n; $i+=2) {
if ($order_total <= $table_cost[$i]) {
$shipping = $table_cost[$i+1];
break;
}
}
Place
//Percentage Mod
if ( strpos($shipping,"%") > 0 && MODULE_SHIPPING_TABLE_MODE == 'price') {
$shipping = $order_total * round(($shipping/100),2);
}
//end Percentage Mod
That is it.
