This release contains corrections for the following GitHub issues:

Sorry for the churn, but v1.2.2 is now available for download.

This version corrects unwanted PHP warnings on the featured_products page.

Re-creating the support thread, since the original one "went missing".

The GA-4 Analytics plugin (available at https://www.zen-cart.com/downloads.php?do=file&id=2368) can be used on Zen Cart sites using 1.5.6b through 1.5.8 without issue. For 1.5.6b installations (or non-standard/older templates), be sure to read the readme since there are a couple of notifications that must be added to template files for the GA-4 Analytics' observer class to do its thing.

Other than that, no core file overwrites, just a couple of configuration settings in your admin.

I reviewed the readme.html but it doesn't mention older versions. How does one install this on 1.5.5f?

One doesn't! The plugin supports zc156 and later.

[Techiant]

Is there another plug in that can handle GA4? Or a manual way to insert code in a header file?

[swguy]

The phrase "The plugin supports zc156 and later" means the plugin relies on internal Zen Cart code changes (often but not exclusively notifiers) that are only present in a specific release or higher.

1.5.5 is quite old and only runs on long-deprecated versions of PHP that are vulnerable to attack. You need to upgrade.

I have installed the GA-4 Analytics update to Zen Cart 1.5.6c however I get an error in the log and Web site doesn't load

PHP Parse error: syntax error, unexpected '?' in /includes/classes/observers/class.ga4_analytics.php on line 309

case FILENAME_SPECIALS:
global $specials, $listing;

$products = $listing ?? $specials ?? []; <<line 309
if (empty($products)) {
break;
}
$_SESSION['ga4_analytics'][] = [
'event' => 'view_item_list',
'parameters' => [
'item_list_name' => GA4_ANALYTICS_SPECIALS,
'items' => $this->getListingItems($products),
]
];
break;


I have put the G- code in the GA4 Analytic admin field.

Any ideas?

[lat9]

You need to update the site to PHP 7.0 at a minimum. The null-coalesce operator (??) wasn't available until that PHP version.

[GordoTheFlash]

Thought it might be something like that, but don't like updating PHP unless instructed.

Thank you

Updated Php version on server to 7 however I though I would see the change appear on the web site admin under the version menu?

But it still has PHP Version 5.6.40

Does it take a while to filter through?
