Undefined Offset 'error' from PaymentModule.php (ps1.6.1.10)

[darvidc]

Hi,

 

I'm running PS1.6.1.10 (after updating recently from PS1.6.1.8) and during some payments I'm getting the following entries in the php error.log?

 

[06-Jan-2017 13:54:23 Europe/Stockholm] PHP Notice:  Undefined offset: 62345 in /var/www/html/ps16/classes/PaymentModule.php on line 233

[06-Jan-2017 13:54:23 Europe/Stockholm] PHP Warning:  Invalid argument supplied for foreach() in /var/www/html/ps16/classes/PaymentModule.php on line 233

 

If I then look at my "PaymentModule.php" (not Overridden in any way) it seems to be something to do with delivery and carrier data! See below Line 233 in red:

 

            foreach ($cart_delivery_option as $id_address => $key_carriers) {

                foreach ($delivery_option_list[$id_address][$key_carriers]['carrier_list'] as $id_carrier => $data) {

                    foreach ($data['package_list'] as $id_package) {

                        // Rewrite the id_warehouse

                        $package_list[$id_address][$id_package]['id_warehouse'] = (int)$this->context->cart->getPackageIdWarehouse($package_list[$id_address][$id_package], (int)$id_carrier);

                        $package_list[$id_address][$id_package]['id_carrier'] = $id_carrier;

                    }

                }

            }

 

Has anybody got any idea about this problem and how to fix it, please?

 

Thanks, In Advance

are any of those carriers produced from a carrier module?  Or did you manually create all of the carriers in your store?

Hi Bellini13

 

I have created all of the carriers manually in my store. I havn't used any Carrier modules.

then i'm afraid you would need to debug that foreach to determine what Prestashop is trying to do, and what carrier data is being used that is causing the issue.  maybe the carrier data has some invalid ascii character ?

Thanks, but I'm running "Live" and I don't know how to do a debug without affecting the shop?

 

I've know turned off the "FS Cache" and the above error and a couple of others seemed to have disappeared from the php "error.log". (I have one remaining error

"PHP Notice:  Trying to get property of non-object in /var/www/html/ps16/classes/module/Module.php on line 2284"

which seems to have something to do with currencies, which if I can't sort it out today, I'll start a new thread for.

 

I can't see any performance difference after turning off the FS Cache (I don't know how to check that either, if I could) but which of the other Cache methods would be recommended to try on my single Debian VPS?

create a test shop and debug there

Any reason you believe one is needed?  if you use mysql query cache, you might not even need a cache.  you just have to test and see which has the best performance without being defective

[darvidc]

Ok thanks, I'll try a test shop and look at the mysql query cache solution as well.

 

Any tips on how I can test performance?
