Problems setting up PayPal Sandbox

Problems setting up PayPal Sandbox

I can not seem to get Sandbox testing working. It just directs straight to the failure page.

So far I have tried setting up new PayPal Sandbox test accounts, entered the new credentials in the gateway settings but with know success.

I have seen on other forum posts that there was an error in the eCart code notified by @Warrio on 6/14/2015 5:30pm.

which stated that the following line of code had to be changed

from: $WA_PP_ECO_Set_params[1][$nextIndex] = "".($WA_PayPal_PayPal_API_TestMode) ."";

to: $WA_PP_ECO_Set_params[1][$nextIndex] = "true";

I tried this change on both confirm.php and pp_confirm.php but still it directs to the failure page.

I dumped the session and the result is as follows:

array(11) { ["WAENCRYPTEDRETURNUSED"]=> bool(false) ["WAENCRYPTEDRETURNSUCCESS"]=> bool(false) ["rtm_application_Items"]=> string(262) "1|WAECART|rtm_application|WAECART|Right to Manage Online Application Form|WAECART||WAECART|0|WAECART|1|WAECART|150|WAECART|1000|WAECART|6|WAECART|3|WAECART|152147432825588538|WAECART|0|WAECART|483.33333333333|WAECART|1 rtm_application (1)|WAECART|333.33333333333" ["WAEC_ContinueRedirect"]=> string(86) "/registered-applications/consent-form.php?entryID=49&submission=No&fee=Unpaid&accID=35" ["eCart_PPECO_System"]=> string(2) "US" ["WA_BillingAgreements"]=> array(0) { } ["PayPal_ECO_Token"]=> string(0) "" ["ECO_Auth_Request"]=> string(1575) " to Manage Online Application Form483.3311Sale" ["ECO_Auth_Result"]=> string(0) "" ["WAVT_consentform_437_Errors"]=> string(0) "" ["consentID"]=> int(8) }

Not quite sure if this gives an indication to what the problem is..

I have zipped and attached all relevant pages.

The user is starts from the consent-form.php page and when they submit the form they're directed to the view-cart.php page and from there taken to PayPal.

Help please.
Thanks in advance.

You should not need to update that line manually... I'd change it back.

The credentials are saved in the webassist/ecart/checkout/credentials/gateways.php

Are you uploading that file after updating your username and password and setting it to test mode? That could be the issue. I'd need FTP access to fully test.

Hi Ray..Ive tried it with or without changing that line of code. I only changed it because of the post by 'Warrio' which you acknowledged, so I assumed it was a noted error that needed changing.

And yes I had remembered to upload the new Gateway credentials.

FTP and database details in PM

Many thanks

The global test-mode is set to false on line 5 of the gateways.php file. That is where you should update it instead of on the page.

When you look at that file are the credentials for the username and password correct for your test-mode account?

Have you created a test-mode user?

I honestly don't use test mode. I usually do live transactions and refund them since paypal also refunds all transaction fees.

What page on the site can I go to to add items to the cart and check out? I'll take a look and debug to see if I can find anything or at least get a relevant error message.

Hi Ray.. you can access the page from URL in PM

It will take you to a simple form.

in the form, choose 'sole' owner, tick all the radio inputs, choose yes for 'Do you live at above property', tick the declaration and submit the form. This will take you to the view cart page which directs to PayPal.

Many thanks.

Your server seems to be blocking communication with the paypal server. The issue might not be with the code at all.

I created a sample page /untitled.php that tries to communicate with the webassist server and that won't work either. You may need to contact your hosting provider and ask why curl isn't able to communicate with the paypal server. You may need to enable something on the server admin control panel.

Hi Ray.. So how come it works in live mode. its only an issue in test mode and the Sandbox.

If this is the case. Whats different about how the server communicates with Sandbox than the live PayPal?

Whats 'Curl' by the way?

Well... maybe you have the paypal domain open but not the sandbox? Are you logged into the sandbox when you test? I think you have to log into sandbox first before doing tests in that session.

The live site uses:

sandbox uses:

Perhaps one is open for communication and not the other? All of the other code is the same for sandbox and live. The only thing that changes is the url of the page. I see that no response is given at all. That usually means it is blocked at the server level. Otherwise you should at least get a permissions error.

CURL is the way php communicates with remote web sites like paypal.

I created a test page:

It shows that you haven't updated your server to TLS 1.2. That is probably the issue. Show that page to your hosting provider and ask them to fix it for you. That is probably the issue.
