Migrating site use the stand alone Express Checkout

I am migrating a website from using the PayPal Advanced method over to use the stand alone Express Checkout.

It turns out I have a copy of that site where I first set it up using Express Checkout, but I need to update the files. I tried rerunning the checkout wizard within that site but it timed out because I have so much custom code in the eCart file.
What I did was create a new site from scratch and did a comparison to see what had changed.

Most of it is pretty obvious to me but I had some questions.

Within the webassist/ directory:

I would assume that most of the files in the newly generated site, would be the correct files to use. I know that credentials are specific to each site and so are the email templates and style sheets, but other than that, can I just copy the other files over as a whole? Including paymentoptions.js?

In the WA_eCart/ directory:

PP_ECO_.php. Both the newly generated file and the older file have the same version number “$WA_PP_ECO_VersionNumber = "63.0”” but are different. Use the newest one?

The pp_confirm.php file:

In the pp_confirm.php file, the “$PPVals =“ is different on the newly generated file. Which should I use?

New file…
$PPVals = isset($_SESSION["WASF_CheckoutWizard_Compact_Default"])?$_SESSION["WASF_CheckoutWizard_Compact_Default"]:array();

Or

Old file just has…
$PPVals = array();

I know the session would be named differently since it's based on the style used but should I include that ternary operator for the correct session?

Use the new version of everything. The only custom file is the gateways.php file which has your usernames and passwords.

Thanks Ray,

Lastly, for now.

On the confirm.php page, (both old and new), a WA Universal Email was generated to send the wa_receipt.php . Why is this in the confirm.php file and again on the pp_confirm.php file?
The one on confirm.php is triggered by $_POST["Payment_submit”], however I do not find a button by that name, so I assume it’s not even used. Is that correct?

With express checkout the only one that is used is pp_confirm.php.

Thanks Ray! I really appreciate the help.

I noticed that with the stand alone Express Checkout, the user only fills in shipping information on the checkout page which is perfect since the shipping address is all we really need.

But, I also see that PayPal returns both shipping and billing address.

I need to make sure that the address entered on the site always remains in the database as they entered it. I don’t want the shipping address to be changed when PayPal returns to pp_confirm.php.
Is it possible to prevent them from changing the shipping address at PayPal?

Here’s what I am worried will happen. Someone will check out using their current shipping address then pay at PayPal using their Mom’s account or spouses account that still contains an old address or a different billing address.

If the email goes out to the shipping department and it shows the billing address in place of what was entered on the site, it could be a problem. Since this is different than how the Advanced and Pro pages work, I wanted to make sure.

Thanks,

You can pass a setting to prevent the shipping address from changing.

You just have to add this with the other parameters being passed:

$nextIndex = count($WA_PP_ECO_Set_params[0]);
$WA_PP_ECO_Set_params[0][$nextIndex] = "addressoverride";
$WA_PP_ECO_Set_params[1][$nextIndex] = "1";

If you can't spot where to add it, just attach your confirm.php page and I can give you a line number. You can add it right after the address or phone number.

That will prevent them from updating the address once passed to paypal.

Thanks Ray,

It goes on the pp_confirm.php page and not the confirm.php page?

I see the params settings on the confirm.php page, such as ReturnURL and CancelURL.

Thanks,
Troy

This would be on the confirm.php page. Sorry I had put the wrong page.

Perfect. Thanks Ray!

One more thing, if you don’t mind. I would like to record the email address of the account they used when paying at paypal.
With the Advanced checkout I always just capture the post returned from paypal. How would I do that with Express Checkout?

//this is what I used in advanced checkout, on the success page
if (!session_id()) session_start();
if ((((isset($_POST["EMAIL"])) ? $_POST["EMAIL"] : "") != ""))     {
$_SESSION["PPAcountEmail"] = "".((isset($_POST["EMAIL"])) ? $_POST["EMAIL"] : "")  ."";
}

Can I just use WA_PP_ECO_GetValue($WA_PP_ECO_GetResult, "Payer") for that address?

Thanks,
