Square Payment Module for Zen Cart [Support Thread]

[billsey5]

Zen-Cart 1.5.5e, PHP 5.4.44, MySQL 5.6.15, Square Payment Module 0.90.

I have the files placed correctly, with square_handler.php in the domain/shop folder and the rest in domain/shop/includes. Application ID and Application Secret are entered correctly from the SquareUp.com app I created. I am seeing the red (Access Token needed). When I click on the green Click here I get the prompt and I enter the login and password for Square which then closes the tab and returns me to my Zen-Cart admin tab. Where can I find a log of the error?

[billsey5]

Aha, a clue perhaps... When I get sent back to Payment Modules I see:

ERROR: module not loaded due to missing language file: C:/Web Files/localuser/CHCG/Shop/includes/languages/english/modules/payment/square_handler.php

And that folder contains a file called square.php, not square_handler.php. Do I need to rename? The setting for the location for domain/shop/square_handler.php is correct on Square, so it doesn't make sense for it to be looking in the languages folders.

[billsey5]

No one has any ideas? I'm kind of stuck...

ERROR: module not loaded due to missing language file: C:/Web Files/localuser/CHCG/Shop/includes/languages/english/modules/payment/square_handler.php

Can you verify that this is what you are seeing?

The system should NOT be looking for that file in that location.

Square.php should be the correct file.

Square_handler.php should be in the root of your site.

I tried again a few minutes ago and didn't get that message again. I still just get returned without a request to authorize from Square. Where should I look for log files that might shed some light on this?

[billsey5]

OK, I found what looks to be a logfile tied to the error. I've tweaked it just to hide the admin directory name. Looks like something to do with checking a version number?

No other idea? Is there a different way to get Square support with Zen Cart? If not is there a suggestion for a replacement for Zen Cart that will work?

ERROR: module not loaded due to missing language file: C:/Web Files/localuser/CHCG/Shop/includes/languages/english/modules/payment/square_handler.php

That would only appear if you put a file named square_handler.php into the /includes/modules/payment directory. The system looks for the module files, and their corresponding matching filename for language file. That error message means you've got a module file present without a matching language file.
And in this situation you should not have a "square_handler.php" file in the /includes/modules/payment directory. It belongs in the root directory of your shop.

Zen-Cart 1.5.5e, PHP 5.4.44, MySQL 5.6.15, Square Payment Module 0.90.

Is it possible to upgrade to a more current version of PHP? PHP 5.4 is really old: its last update was Sept 2015.

I am seeing the red (Access Token needed). When I click on the green Click here I get the prompt and I enter the login and password for Square which then closes the tab and returns me to my Zen-Cart admin tab.

The normal flow is:
- Click green button
- it takes you to the Square site, asking for login if you're not already logged in. Presents an authorization prompt if not already authorized.
- returns you to your store admin
- If the "Access Token Needed" alert is still showing, press F5 to reload the admin page in your browser.

I tried again a few minutes ago and didn't get that message again. I still just get returned without a request to authorize from Square.

Is the directory you've been quoting (C:/Web Files/localuser/CHCG/Shop/) a local development PC? Or is it the live production server for your domain?
What browser/s are you doing this Admin / SquareLogin in?

Where should I look for log files that might shed some light on this?

Any logs generated by the module are stored with other error reports in the /logs/ folder as "myDebug-xxxxxxxx.log" filenames.

Let me try to cover everything, I have gotten closer though. The server is live, but not visible to the public yet. I'm using Firefox 59 and have tested with IE and Edge as well.

The cert is a Let's Encrypt cert. It seems like curl has problems with those even though no one else seems to. After using the test script for curl and putting a replacement cacert.pem file in the PHP environment, and upgrading the site to 5.6 the test script was able to run completely.

Once curl would work correctly the green button acted as it should and Square was active on the site.

I now find that I can add things to my cart, go through the checkout process until I get to the confirm my order where after I push the button it waits for a minute or two and then gives me a 500 - internal server error. A refresh of the page gives the warning about resending data the take me back to the payment information page with a "Unable to process payment due to a communications error. You may try again or contact us for assistance." notice.

Let me know where I can look for more info on fixing this.
