Error on Add to cart

Hi,

HikaShop uses the PHP function called bccomp in some areas when comparing floating numbers for greater precision / control.
It seems that the bcmath compat was added to Joomla for servers where bcmath is not available in PHP.
And the deprecated message there comes from that bcmath compat library.
This comes from changes made in PHP 8.2 :
exakat.readthedocs.io/en/latest/Referenc...#deprecated-callable
I found one instance on the web with someone else simply turning off the error reporting to avoid the message from popping up:
github.com/SondagesPro/pdfReport/commit/...5d6a5cd0fbee3387R821
Now, from what I can see on the official github of the bcmath_compat library, this deprecated message has already been dealt with:
github.com/phpseclib/bcmath_compat/blob/master/src/BCMath.php
Similarly, you can change the line:
return call_user_func_array('self::' . $name, $arguments);
to:
return call_user_func_array(self::class . "::$name", $arguments);
and it will remove that deprecated message.
In the long term, Joomla will update the bcmath_compat library and it will remove the deprecated message.

You could also turn off the "error reporting" in the Joomla configuration. That should actually be the case on any live website for security reasons.

Hi,

No. This is not an error. It's a deprecated message. It tells the developer that they need to adapt the code for futur versions of PHP.
It doesn't change the behavior of the system. So your issue with Square is not linked to this. That's why I brushed it off in the other thread ( www.hikashop.com/forum/payment-methods/9...stration-issues.html ).

I specifically researched the deprecated message here as you posted it as a separate message. I also provided the solution in my previous message here. If you apply the change, you'll see that the deprecated message doesn't appear anymore. And you'll see that you'll still have the same issue with Square as the two are not linked.

So I think we can close this subject here and focus on the real problem you have on the other thread.
