Product shipping cost estimation

[MTechMgr]

Hello. I have made an article and loaded a module inside it, so in product details page the customer can click to read a shipping estimation cost.
The link loads a popup window with the article and gets the product weight thus etsimating the cost for dispatch.
For products <=3 kg the cost shows up perfect. For products >3 kg I have problems. Here is the code inside flexi custom code module.

Code: [Select]

<?php
$ZoneCost = 3;
$CostPerKilo = 1;

if ($product_weight <= 3) {
$rate = number_format($ZoneCost,2);
echo $rate. " €";
echo " excluding VAT.";
}
elseif ($product_weight > 4){
$rate = number_format($ZoneCost+($product_weight - 3)*$CostPerKilo,2);
echo $rate. " €";
echo " excluding VAT.";
}
?>
Can someone help pls?

surely elseif ($product_weight > 4){

should be  elseif ($product_weight > 3){

or better just }else{ ......

Code: [Select]

<?php
$ZoneCost = 3;
$CostPerKilo = 1;

echo $rate. " €";
echo " ex VAT.";
}
elseif ($product_weight > 3){

have u checked what $product_weight really is?

a string, an integer etc etc ..  type it to an integer ?

[MTechMgr]

well... where can I check it?
in backend i put kgs? for weight with the value 5.00 kg

come on.. this is basic php.. hardly what this forum is for

if u could write the above code then surely you can also echo out some values and debug it?

sorry i got lost searching in ps_shipping_method.php in classes folder

I didn't write the code I just made some changes to it and tested. I don't know php coding.

  i got dizzy seraching for the bug

the code above has nothing to do with core VM functions or methods.. it is just a simple php calc

and unless you know that $product_weight is actually the actual "product weight" as an integer then it will just return 3 always

It's a decimal (10,2) in table vm_product

Code: [Select]

<?php
settype($product_weight, "integer");
$ZoneCost = 3;
$CostPerKilo = 1;

if ($product_weight <= 3) {
$rate = number_format($ZoneCost,2);
echo $rate. " €";
echo " πλέον ΦΠΑ.";
}
elseif ($product_weight > 3){

$rate = $product_weight;
echo $rate. " €";
echo " πλέον ΦΠΑ.";
}
?>
is this correct?

[MTechMgr]

What can I do now?
I strongly need this solution 

[GJC Web Design]

employ a coder...   you can't expect free coding solutions from a forum esp. as this has nothing to do with VM..

[MTechMgr]

I don't expect sth from the forum. Thx for the advice in the problem
