How do I reset an ecart variable

How do I reset an ecart variable

I have some logic where if certain conditions are true, I need to change the value of a variable called ShipCalcMethod in the cart. What is the syntax to do that? I can query it with eCart->DisplayInfo("ShipCalcMethod"), but how do I change it?

Thanks,
Nina Macdonald

you would do this in a calculation in the cart object, so that the value can be reset on an item by item basis.

you could create a calculation called "resetShipCalcMethod". for examples sake i will reset the ShipCalcMethod if the session variable "reset" equal 1

resetShipCalcMethod abs(isset($_SESSION['reset']) && $_SESSION['reset'] == '1')?[ShipCalcMethod] = '':''

I don't think that's quite what I need

Here is my code. This is not in the WA_eCart newProducts_PHP.php file, but earlier.

while (!$newProducts->EOF()) {
if ($newProducts->DisplayInfo("ShipCalcMethod") == "call"){
$quote++;
} elseif ($newProducts->DisplayInfo("ShipCalcMethod") == "fixedF") {
if($mattresses > 0 ) {
if ($newProducts->DisplayInfo("Quantity") <= $mattresses ) {
$newProducts->itemShipCalcMethod ="free";
$mattresses -= $newProducts->DisplayInfo("Quantity");
} else {
$newProducts->ItemShipCalcMethod ="fixed";
}
} else {
$newProducts->ItemShipCalcMethod ="fixed";
}
}
$newProducts->MoveNext();
}

I thought that $newProducts->ItemShipCalcMethod ="fixed"; would re-set the variable for that particular product/ship method, but it doesn't. Is there some syntax I can use to do this on the individual item in the cart.

At the beginning of this, I have already computed how many mattresses are in the order. Any foundation ships free if there is a off-setting mattress.

you need to do this in a calculation like I outlined previously.

Yes, but I don't understand your original post

Are you saying that I can just say [ShipCalcMethod] = "free";

in my code and it will know what product I am on? I don't really need the whole line you gave since I already have my test.

Thanks,

using just [ShipCalcMethod] = "free" will always set to free no matter what.


using the abs() function, you can use other variables to determine whether the ShipCalcMethod column should or should not be set to free.

the abs function returs true if the equation in perenthisis is true:
abs(equation)?execute if true:execute if false;

abs($var == '3')?[ShipCalcMethod] = 'free':''

this will set ship ShipCalcMethod to free only if $var is equal to 3.

Here's what works

I'm not sure you ever grasped that I needed to set the Shipping Method individually for a given product. Perhaps you did and I couldn't understand what you said. However, with your help, I did create a function that resets the value of the variable. Here, for later readers is my function with thanks to DisplayInfo().

function ModifyShipCalcMethod($newMethod) {
if (!$this->IsEmpty() && !$this->EOF()) {
eval("\$this->Items[".$this->DisplayIndex."]->ShipCalcMethod = "."\$newMethod".";");
}
}

I put this function in WA_eCart_Definition_PHP.php
I called it like this

$newProducts->ModifyShipCalcMethod("free"); OR
$newProducts->ModifyShipCalcMethod("fixed");

Yes, i did grasp that.



Calculations are performed on a per item bases.


glad you found a way to get it working.
