URGENT: Yet another payment module not working

movieseals · March 29, 2020

Using Bellini's Interac module, which used to work fine, with the TB compatible version and TB 1.1.x - latest version. I did check the configuration table in the DB for INTERAC_OS_PENDING_PAYMENT and it had indeed the wrong order status, which I fixed, but unlike my other module, the customer still gets a 500 error and I get this in the logs:

Decoded exception

Too few arguments to function iemt::execPayment(), 0 passed in /home/zbookstore/public_html/modules/iemt/controllers/front/validation.php on line 51 and exactly 1 expected

in file modules/iemt/iemt.php at line 237

This error has nothing to do with newer version of TB.

this is related to PHP7+.

the message is very clear about the reason.

look at file: modules/iemt/controllers/front/validation.php on line 51.

this function require 1 argument which is not passed.

this function exists on file: modules/iemt/iemt.php at line 237, now i can't tell much about what is expected for $old_cart. but i guess you can try to pass the cart from validation.

so try changing line 51 in validation.php file to: $this->module->execPayment($cart);

if you can show the rest of the code after line 247 it will be better.

Here is the whole code. I put line 50 in red, and everything from 247:

As you can see this variable is not even being used in the function.

anyway just do this and you should be fine.

If I change line 51 with $this->module->execPayment($cart);

now the entire site gives a 500 error.

are you sure you are changing in the validation file?

all you need to do is to change from:

$this->module->execPayment(); to $this->module->execPayment($cart);

I misunderstood you. Rookie mistake. 😞 It works now. Thank you so much for your assistance!

Also, if possible, please contact developer of the module and ask them to adjust their code

Will do. I had gone to the website and downloaded the latest update, but it still has that issue.
