Zenid issue

[hockey2112]

Hello,

Here's a link to the site in question: http://tinyurl.com/cp3t8ww

If you then click on the "Relish" link , you will likely have a zenid appended to the url with an ampersand (website.com/relish&zenid=blahblahblah). Unfortunately, this gives you a Page Not Found error message. If you then click the "Relish" link again (or any other link), the page loads correctly and no zenid shows up in the URL (since the zenid is set at that point, I am assuming).

If you go to the home page in a different browser and then click on the "Upcoming Shows and Markets" link, you will see the zenid appended to the url with a question mark. When you click this, it loads up the next page just fine.

The difference between those two pages is that the Upcoming Shows page is a simple EZ page, and the Relish link is an EZ Page that links to the internal URL "relish", which is the URL assigned to the Relish category via CEON URI Mapping.

I emailed the CEON developer, and he said that it isn't an issue with Ceon URI Mapping, it that his module doesn't make the mistake of appending an ampersand instead of a question mark. He said I should check the menu module being used, but it is simply the stock Zen Cart menu.

Any ideas on how to fix this issue?

Thanks!

Selecting the Relish link does not generate a 404 error for me

I did get a Page Not Found the first time I clicked the Relish link. It worked correctly the second time.

I find this happens on first click of all your pages ...

Try turning off the SEO/rewrites and see if that clears up this problem ...

I notice that error occours because the url is http://sunshinefoodco.com/relish&zenid=ss0a6lap50cn4l9vtpdl4ssjo5 in spite of http://sunshinefoodco.com/relish?zenid=ss0a6lap50cn4l9vtpdl4ssjo5

I hope it's useful for you...
I'm having the same problem but i can't solve ... at the moment!!

I notice that error occours because the url is http://sunshinefoodco.com/relish&zenid=ss0a6lap50cn4l9vtpdl4ssjo5 (instead) of http://sunshinefoodco.com/relish?zenid=ss0a6lap50cn4l9vtpdl4ssjo5

I'm going to go out on a limb and guess this behavior only appears on EZ-Page links using the "Internal URL" field to point to a category or product. This is a common problem encountered due to the way EZ-Pages handle the "Internal URL" or "alt_url" field. Basically it passes the entire contents of this field to zen_href_link as the "page" with no parameters instead of correctly reading the page and splitting off the parameters.

There are a couple workarounds:

1. Configure Zen Cart to use "Cookie Domain" and "Force Cookie Use". These settings can be changed from "admin" -> "configuration" -> "sessions". In my experience, once these settings are enabled only users who have disabled cookies will ever see the zenid in the URL.
2. Use a full URL in the "External URL" including the "http://".
3. Use zen_href_link directly in your templates instead of using the EZ-Page header, footer, and sidebox.

Hi,

That's exactly what is happening.

There are a couple workarounds:

1. Use zen_href_link directly in your templates instead of using the EZ-Page header, footer, and sidebox.

That is also my recommendation.. the site was built using dynamic Zen Cart URIs but now it has moved across to using static URIs the EZ-Page internal URI functionality is no longer "appropriate" and I recommend changing to using zen_href_link. If Zen Cart had originally been built to use static URIs then this would already have been the case I'd imagine and this problem wouldn't have appeared. The solution is easy as you point out. :)

All the best..

"correctly reading"? Can you explain what you mean?

Hi,

"correctly reading"? Can you explain what you mean?

Actually, what I've said is wrong.. the problem isn't that the links aren't using zen_href_link, it's that a "feature" of zen_href_link() is that it can't cope with URIs that are static but don't have parameters.

In the modules/ezpages_bar_header.php file code like the following is used:

zen_href_link($page_query->fields['alt_url'], '', ($page_query->fields['page_is_ssl']=='0' ? 'NONSSL' : 'SSL'), true, true, true) 

For this to work properly the zen_href_link() function requires that a parameter list is supplied, in which case the URI has a "first" parameter with a question mark prepended. The session ID is always appended using an ampersand because of the code:

$separator = '&'; 

In Ceon URI Mapping I made it so that no such thing could happen. Sorry, should have also got in touch to have this "feature" fixed for Zen Cart itself. Code from Ceon URI Mapping which can be an easy basis for making the same changes to the zen_href_link function:

if (strlen($parameters) > 0) {
                // Must add the parameters to the link
                $link .= '?';
                
                while (substr($parameters, 0, 1) == '?' || substr($parameters, 0, 1) == '&') {
                    $parameters = substr($parameters, 1, strlen($parameters) - 1);
                }
                
                $link .= zen_output_string($parameters);
                
                $separator = '&';
            } else {
                $separator = '?';
            } 

Hope that helps!

All the best...

Hi,

Suppose I may as well make things easy :)

This code:

if (!$static) {
      if (zen_not_null($parameters)) {
        $link .= 'index.php?main_page='. $page . "&" . zen_output_string($parameters);
      } else {
        $link .= 'index.php?main_page=' . $page;
      }
    } else {
      if (zen_not_null($parameters)) {
        $link .= $page . "?" . zen_output_string($parameters);
      } else {
        $link .= $page;
      }
    }

    $separator = '&'; 

should be changed to:

$separator = '&';
    
    if (!$static) {
      if (zen_not_null($parameters)) {
        $link .= 'index.php?main_page='. $page . "&" . zen_output_string($parameters);
      } else {
        $link .= 'index.php?main_page=' . $page;
      }
    } else {
      if (zen_not_null($parameters)) {
        $link .= $page . "?" . zen_output_string($parameters);
      } else {
        $link .= $page;
        
        $separator = '?';
      }
    } 

That'll prevent any errors occurring when the session ID is appended.

All the best...
