Paypal Debugging + small glitch in paypal_connect.php

[mbdiscover]

1) To enable Debugging for Paypal Module set the debugging level from 0 to 1

 

Enter your Database for prestashop

Navigate to Table: [yourDatabase]_configuration

Modify Row: "PAYPAL_DEBUG_MODE" Value:1

 

 

 

2) There is a small glitch in the offical module "paypal_connect.php"

 

Private function _connectByFSOCK($host, $script, $body)

 

The row 127 with [ $tmp = ''; ] must be moved to the top of the function.

If not an error PHP can occur.

 

The reason is, the IF Clause doesnt init the $tmp on Failure.

Thus the return statement will not work properly.

 

 

 

3) If you changed the paypal_debug_mode = 1 you will get a response in the prestashop frontend.

 

Without:

Please try to contact the merchant:

With:

 

Please try to contact the merchant:

 

Making new connection to 'api-3t.sandbox.paypal.com/nvp'

Connect failed with fsockopen method

PayPal response:

->

 

 

4) The reason behind the error might be the PHP Setting of Hosting Provider.

The PHP configuration

"allow_url_fopen" = "false"

"disable_functions" = might contain "fsockopen"

 

Hope this will help, as it took me some hours to figure the trouble out.

No visible error in frontend is always an annoyance.
