Meta Box

Hi Peter,

any update here?

thank you

Ok, so I’ll change everything to the WC APIv3 now. Can you please confirm that from your side this is future proof?

Thank you

I tried to update via WC API v3 like this, did not work:

{
"meta_box": {
"relatedlist": [],
"untertitel": "Der ausagekräftige Untertitel",
"format": "",
"einband": "Softcover",
"illus": "",
"umfang": "456",
}
}

If I update like this, it does work:
{
"meta_data": [
{
"key": "umfang",
"value": "456"
}
]
}

This is still with the modified code of your plugIn.
And it I would need to change the whole import script to adjust to that.

The error is thrown when I try to update the metabox-data with wp2 API for a product:

Hi Peter,

No, I just have woo commerce products, nothing else. I’m importing/updating data from a database with a python script to the site, it was working fine, after updating to 2.02 it was not possible to update the products anymore and the error message suggested an error in line 9.

What I do:
Getting data and creating a woo simple product through Woo API.
Creating a post in custom post type "autor" with WordPress API.
Creating a post in custom post type "translator"with WordPress API..
Updating metabox fields and relations through WordPress API.

Running a cronjob and updating new versions of the connected database.

After removing the code it is running smoothly again.
I was wondering, as you were updating to make the product update possible, but here it was the opposite result.

I started this project in October last year and I could post/update the woo commerce simple product without any problem. In summer, I got an error 500 but the fields were still filled with the correct data.
Now, I get the error and the fields don’t contain any value.
Here is a sample json I send to the Rest API:
