Cross Sell Advanced [Support Thread]

I have been searching and had a question to you lat9 as you obviously know what you're doing.

I have selected my database in MyPhPAdmin and run a Search on all tables for the word "Xsell". It returned 2 results in admin_pages amd 4 results in configuration. When I look at these results within these tables they all relate to your plug in. So this has to be telling me that the previous plug in is completely erased. I have also looked at the products_xsell table to insure that there are no duplicate entries.....and nothing.

As this is a real head scratcher and I cannot go live with this result, would the old version of this plug in (the one I'm currently using on my v.1.5.5 site) work in zen cart v.1.5.7 I know that there have been some fundamental changes to zen cart....so thought I'd ask someone who is integrally involved.

Thanks again,

Jeff

Jeff, that YourStore template is very, very invasive. I'll suggest that you search through your storefront files for **xsell **to see where it's being used other than the plugin itself.

Hi lat9,

Thanks for you help and suggestion on searching my storefront files. I will definitely do this and post back.

Thanks again,
Jeff

Hi lat9,

My apologies and thank you for you help......the module works perfectly!! After several hours of trying this and searching that, I tried installing the old Multi Cross Sell v 1.03 module from my zen cart v.1.5.5 into my test v.1.5.7 and it worked and displayed correctly. I did notice that it displayed duplicate product titles but the lower one was in bold.....so it got me to thinking.

As I had not installed the images onto my v.1.5.7 test site (folder way to large with over 2300 products) I wondered if what I was seeing on my test site with your module installed with simply duplicate product titles as one is the displaying title and one was for the Image-Alt function. I removed the Multi Cross Sell and re-installed your Cross Sell Advanced II module and uploaded images for just one product into my test v.1.5.7 site. It worked!

Once again, my apologies for not realizing this earlier......and thank you once again for your help.....it is much appreciated.

Jeff

Suggestion on next push - add the link to the template modification instructions to the text readme file (or perhaps delete it entirely so you don't have to maintain two copies).

ZC 1.5.8 changes

• change ./includes/modules/xsell/category_product_selection.php to call zen_draw_pulldown_products instead of zen_draw_products_pull_down.

Otherwise works like a champ. Note that the old Related Products module no longer works with 1.5.8/PHP8 and will require significant updates.
I am pointing people to this module instead.

I'd quite forgotten that I had this in GitHub! Was that function name changed from 157 to 158? Just trying to understand the "why" for the change.

Yes, the function name was changed. I submitted a PR to your repo to fix.

Yep, saw the PR but didn't understand the why.

https://github.com/zencart/zencart/pull/5439
https://github.com/zencart/zencart/pull/4083

One of the function renames from 1.5.8.

Done, now in v2.0.2 readme.html

v2.0.2 of Cross Sell Advanced II is now available for download: https://www.zen-cart.com/downloads.php?do=file&id=2334

This release provides integration with zc158; see GitHub issue #7 for additional information.

Question about the help: you said

Note: If your site is using the ZCA Bootstrap Template, don't forget to copy the file /includes/templates/bootstrap/templates/tpl_modules_xsell2_products.php to your "clone" of the template!

Didn't you mean the other way around? Something like:

Note: If your site is not using the ZCA Bootstrap Template, don't forget to copy the file /includes/templates/bootstrap/templates/tpl_modules_xsell2_products.php to your template!

Or maybe:

v2.0.3 of Cross Sell Advanced II is now available for download: https://www.zen-cart.com/downloads.php?do=file&id=2334

Corrects the admin tool's pagination, thanks to @webchills.

Note: This might work with zc200, but I've not tested in that environment.

Google Merchant Center next doesn't like " in the titles.

So I use HTML entities like " instead of "

The cross sell items (related products) unfortunately show " instead of "

Thank you for updating this plugin lat9!

I am installing it in a v.2.1 upgrade and noticed that after uploading the files all installed correctly, I received the install message at the top of my Admin and I have the config areas in Admin.

When I go to edit the tpl_xxx_info_display.php files the tpl_document_general_info_display.php, tpl_document_product_info_display.php,and the tpl_product_free_shipping_info_display.php are very changed files from past Zen Cart versions.

There isn't the :

sections in these files any longer. When I simply added the code to the end of the files, it didn't throw any errors, but my index page now shows nothing in the center column (no products, no featured, no specials) just a white blank.....and again no error in the Debug Logs.

I have added the code to my tpl_product_info_display.php in the correct spot.

If I click on a category to go in, I then see the products in this category in my centre column as normal.

Any ideas on why it is not displaying on the index page???

Not without a link to the site.

The site I am working on is in my local computer as I am in the process of upgrading....unfortunately it is not on a live site.

I know this makes it extra difficult to diagnose....I only have the stock Zen Cart v.2.1 database installed with demo products to insure that my current live site database isn't causing any issues.

I do have a custom template, and the only file that is in my custom template (all others uploaded from this plugin are inside the stock Zen Cart) is the tpl_product_info_display.php which is the stock file with the added Cross Sell Advanced coding near the end of the file.

All was working and displaying properly on the development site before installing this plugin...and I am only installing one plugin at a time....testing and using it to insure to errors before moving onto the next.

Does this help?

In trying to decipher this error....the only error showing in my Debug Logs was for a plugin I have yet to install, ZX Slideshow, but is throwing an error as my Custom template file includes some code that is calling for this plugin.

I decided to uninstall the Cross Sell plugin first, (deleted all uploaded files and ran the SQL Unistall). I then installed the ZX Slideshow plugin, and everything in my Index page center column magically appeared!

I then installed the Cross Sell plugin once again, went to Admin and see it in the Admin->Config and in the Admin->Catalog.

Now when I load my site I get a total white screen with the following in the Debug Log:

I have double checked and reuploaded the file the Admin/includes/init_includes/init_xsell_config.php without any change.

Would you be able to shed some light on where I've gone wrong??

Thanks for your help.

From the log, it appears that you've copied the /admin/includes/auto_loaders/config.xsell.php to the storefront directory /includes/auto_loaders; remove that file that's in the wrong place.
