URL Parameters Break Links

[lindasdd]

Is there a trick to getting URL Parameter links to work with category and manufacturer pages? Or rather, is it normal that URL Parameters break links?

My sites that rewrite URL's to be static work fine with URL Parameters.

My sites without URL rewriters cause links with URL parameters to lead to pages that display 'There are no products to list in this category.'

Product links seem to be ok.

A link to one of the site's displaying this behavior?

Was hoping not to have to provide a link

Here is an example. Manufacturer page is:
https://www.lindasdietdelites.com/in...turers_id=376?

Link with URL Parameters might be:
https://www.lindasdietdelites.com/in...719emailtolist

What plugin is injecting those utm_* variables?

The best way is a redirect. Is it all manufacturers pages being tagged or just some?

It isn't a plugin. It is basic Google UTM Parameters. They can't be hard coded into a redirect because they change all the time based on different marketing.

Think I figured it out. Because there is already a Query in the link (?) you need to start the UTM section with an & instead of a ?. For example:
https://www.lindasdietdelites.com/index.php?main_page=index&manufacturers_id=376&utm_source=Funnel1&utm_medium=ema il&utm_campaign=032719emailtolist

You could just remove the utm_* stuff by modifying init_includes/init_canonical.php (put it in init_includes/overrides/init_canonical.php). Add these parms to the $excludeParams array.

Or could use an observer off of:

$zco_notifier->notify ('NOTIFY_INIT_CANONICAL_PARAM_WHITELIST', $current_page, $excludeParams, $keepableParams, $includeCPath);

And update $excludeParams to accomplish the same without the override.

Yes, that should correct the issue.
