TaxJar Issue - Composer Related?

Zen Cart 1.57d. PHP Version: 7.3.33. Not using any other plugins related to checkout process.

Testing the newest chuckphillips TaxJar plugin so I can get away from taxcloud.

Error Message

[10-Dec-2022 18:29:20 America/New_York] PHP Fatal error: require(): Failed opening required '/home/xxxxxxxxx/public_html/taxjar/vendor/autoload.php' (include_path='.:/opt/cpanel/ea-php73/root/usr/share/pear') in /home/xxxxxxxxx/public_html/includes/functions/extra_functions/taxjar.php on line 5

Confused.

autoload.php doesn't exist in that folder

Do I need to do something related to composer on my server or am I not understanding something else?

sorry to bump, this is the taxjar/composer.json in the plugin. thought this may matter?

Yes, its a composer issue. Sorry Ill update the docs to cover that.

Basically, you run composer and it installs the latest Taxjar client api into your store. From a command line, navigate to your store's folder and execute

Code:

---

composer require taxjar/taxjar-php

---

Taxjar's instructions for the above are here:

https://developers.taxjar.com/api/gu...php-quickstart

Then, to prevent a warning about your PHP version, you will need to mod one more file:

../vendor/composer/platform_check.php

Change:

Code:

---

if (!(PHP_VERSION_ID >= 80100)) {
to
if (!(PHP_VERSION_ID >= 70300)) {

---

We run the taxjar client on PHP 7.4 and have used it on 7.2 and 7.3. The latest Taxjar client is asking for php 8+, but has been successfully installed on earlier versions. YMMV

I just asked support at my host to help me with this.

Was told the following:

I ran the command from the document root, but getting an error : [RuntimeException]
Could not scan for classes inside "not_for_release/testFramework" which does not appear to be a file nor a folder

Now have a vendor folder located at the root with a couple dozen subfolders.

I see a composer and taxjar folder within the vendor folder.

Not seeing ../vendor/composer/platform_check.php that u mentioned

Not seeing an autoload.php file either.

thx for earlier response.
I've never used composer and I avoid CLI because I have limited knowledge at best
Guessing my issue is with Composer installation??

Request the hosting support to remove the taxjar/taxjar-php

When I was trying to run an update I was getting error message related to my version of php.

Will updating my php version to 8.0 just before I run the composer require again then roll back to php 7.3 give me what I need since the install is looking for php 8.0?

The vendor folder should be inside the taxjar folder. Try moving it and its contents there.

Or run composer from the public_html/taxjar folder.

Can't move the vendor folder that was my host support helped me with.

I ended up running the composer require taxjar/taxjar-php command on a different domain that I don't use as a test (and out of fear).

I copied the vendor file from that host and placed it in the public_html/taxjar.

Seems to be working.

Hate to do things in such a roundabout way, but I never used composer and I should have tested it first in a dev environment.

Also

I'm getting the following error:

#1 ot_taxjar->__construct() called at [/home/xxxxxxxxx/public_html/admin/modules.php:106]
#2 require(/home/xxxxxxxxx/public_html/admin/modules.php) called at [/home/xxxxxxxxx/public_html/admin/index.php:11]
--> PHP Warning: Use of undefined constant MODULE_ORDER_TOTAL_TAXJAR_SORT_ORDER - assumed 'MODULE_ORDER_TOTAL_TAXJAR_SORT_ORDER' (this will throw an Error in a future version of PHP) in /home/xxxxxxxxx/public_html/includes/modules/order_total/ot_taxjar.php on line 20.

function __construct() {
$this->code = 'ot_taxjar';
$this->title = MODULE_ORDER_TOTAL_TAXJAR_TITLE;
$this->description = MODULE_ORDER_TOTAL_TAXJAR_DESCRIPTION;
$this->sort_order = MODULE_ORDER_TOTAL_TAXJAR_SORT_ORDER;

}

So I looked at the ot_tax file. Based on that I made the following change:

function __construct() {
$this->code = 'ot_taxjar';
$this->title = MODULE_ORDER_TOTAL_TAXJAR_TITLE;
$this->description = MODULE_ORDER_TOTAL_TAXJAR_DESCRIPTION;
$this->sort_order = defined('MODULE_ORDER_TOTAL_TAXJAR_SORT_ORDER') ? MODULE_ORDER_TOTAL_TAXJAR_SORT_ORDER : null;
if (null === $this->sort_order) return false;

}

Nothing has blown up yet, so maybe that'll work?

Thx again chuck

Just got this message:

--> PHP Warning: sizeof(): Parameter must be an array or an object that implements Countable in /home/xxxxxxxxx/public_html/includes/classes/order_total.php on line 66.

Not sure if my change above may have caused this or just the timing of a customer making a purchase?

Using PHP 7.3

No code change should be necessary at this point. I think you should roll that back.

The constant MODULE_ORDER_TOTAL_TAXJAR_SORT_ORDER is undefined for some reason. That is set in the Order Total configuration for the Taxjar module. What do you have for that setting? It is expecting a number.

I really don't know any PHP, so thanks for ur time.

When I look for examples (like ot_tax.php) or similar files I went into the developers tool kit and searched: $this->sort_order

Seeing examples like ot_cod_fee.php, ot_group_pricing.php, flat.php, etc.

They are all defining the constant for $this->sort_order.

When I look at the bottom part of the ot_taxjar page, I'm seeing the numeric fields are part of the insert statement.

I'm getting the following warning running 7.3 using the original ot_taxjar.php:

#1 ot_taxjar->__construct() called at [/home/xxxxxxxxx/public_html/stifF-qrU-cHill/modules.php:204]
#2 require(/home/xxxxxxxxx/public_html/stifF-qrU-cHill/modules.php) called at [/home/xxxxxxxxx/public_html/stifF-qrU-cHill/index.php:11]
--> PHP Warning: Use of undefined constant MODULE_ORDER_TOTAL_TAXJAR_SORT_ORDER - assumed 'MODULE_ORDER_TOTAL_TAXJAR_SORT_ORDER' (this will throw an Error in a future version of PHP) in /home/xxxxxxxxx/public_html/includes/modules/order_total/ot_taxjar.php on line 20.

I think the change I attempted above (if it was correct by chance) should have also included an additional line: $this->output = array();

//$this->sort_order = MODULE_ORDER_TOTAL_TAXJAR_SORT_ORDER;
$this->sort_order = defined('MODULE_ORDER_TOTAL_TAXJAR_SORT_ORDER') ? MODULE_ORDER_TOTAL_TAXJAR_SORT_ORDER : null;
if (null === $this->sort_order) return false;

$this->output = array();

Figured the undefined constant was defaulting to true and making sort order values in the db record available?


I'm not saying you're wrong, just trying to understand the mod.
