Hello Hikashop Team
Hope you are all well and safe. Sorry, but I have a little problem with Variant updating...

When I try to select an alternative characteristic from the existing characteristic options I get a script error, and the characteristic is not changed.

For instance, when I want to change a Colour from the existing colour, "Bracken" to become another created colour "Bracken (waiting for stock)", the change is not saved and the browser reports "Uncaught ReferenceError: hikashopUpdateVariant is not defined..."

This seems to be happening since a recent update to the latest version of Hikashop.
Any help appreciated.
Kind regards, Bob

Hi,

Please download again the install package of the latest version of HikaShop on our website and install it on yours.
It will add a patch which should fix that.

Fantastic! Thanks Nicolas for staying up late to answer this. All working well here! Hope you, Team Hika and family are keeping well and managing to find some peace and calm during these crazy times. Thanks again and stay safe.

Ah, spoke too soon.
We use the Attach Invoice Plugin, and since the update when I try to download the Invoice I receive an error message:
<< >>
And the invoice is not downloaded.
Where should I look to solve this?

Forget that - a couple of hours and the issue has disappeared, sort of. Perhaps some caching thing...

Hi,

I don't think this is linked to the update.
This error means that somewhere in the invoice you have a br tag not written properly.
It's hard to say where though.
What I would recommend is to add the code: before the code: in the file plugins/system/attachinvoice/attachinvoice.php and then try again.
That way, you'll get to see the HTML of the invoice before the PDF is generated out of it. Then, you can search for that br tag in the HTML of the invoice in order to better understand where the problem is coming from.
It could be the store address, it could be the name of a product, the address of the customer, the address format, etc.

Thanks Nicolas
I think I've found it... some code I was trying, to add a custom product field to invoice.php in ../attachinvoice/attachinvoice

So, easy to fix the <br/>. Just a little stuck on how to add a custom product field (in our case 'nmpartnumber'). Any tips?

I've tried echo $product->order_product_nmpartnumber;
And a number of other methods, with no success.

Hi,

The custom product field data is not loaded in the invoice.
You could do like that: This supposes that the "column name" setting of your custom product field is "nmpartnumber".

Brilliant - that's helped me a lot! (French colleagues need every little detail on every invoice for their system).
I made only one tiny change, if it helps others: Merci beaucoup encore!

Sorry to raise this again, now way off the original topic.
Can I use a similar method to access a custom field of type Item?

Each of our bicycles have a Frame number, which we want to record on each invoice, as well as in the item field, "itmframenumber"

If it helps, this is my first naive attempt in the file attachinvoice/invoice.php
There is data in the itmframenumber field which shows on the back-end order details.

Hi,

The custom item field data is directly avaliable in $product.
So you can just do:
echo $product->itmframenumber;

Another question: What's the emoji code for <<feeling like an idiot>>? Thanks a lot Nicolas

No worries
