How to send an Object as Order Meta Data?

[mariusbolik]

Hello,

I installed a Plugin to view the meta date of an order. If I place an order through the Website, the field looks like this:

GraphQL returns it as

{
  key: "_eh_pe_details",
  value: "Array"`.
}

How needs the data to look like that I am sending to WooGraphQL?
I tried to send JSON, but it doesn't work:

What is the right way to send a JavaScript Object?

Regards,

@mariusbolik It seems the data isn't being serialized into a JSON on the client side. Have you tried running it thru JSON.stringify()

I'm having this same issue, where I'm trying to get the tracking data that is placed in meta fields by the Shipment Tracking plugin. The problem is that the return via gql is an actual string that says "Array". How can we get the nested data?

From the plugin docs:

The Shipping Tracking plugin stores the tracking information in the order meta with the meta key _wc_shipment_tracking_items. It’s an array with the following structure:

- tracking_provider — String of predefined provider
- custom_tracking_provider — String of custom provider
- custom_tracking_link — String of custom tracking URL
- tracking_number — String of tracking number
- date_shipped — Timestamp of shipment date

Sorry for the late response!

This happens when I JSON Encode the content:

Here is the critical part of the Object. See the _eh_pe_details value:

We use the Webtoffee PayPal Plugin. But other Payment Plugins also need objects to be send to the backend.

This is my solution to problem, but I wouldn't recommend it since it involves changing data type definition in plugin file. What it does is looking if is_array for String type is true, and if so it json_encodes the value. This allows query result to be json string which can be parsed with JSON.parse.

How it can solve Your problem? Probably Your way of sending data is valid and the problem You're facing is data type value that query returns.

 #\includes\type\object\class-meta-data-type.php  line 43

'value' => [
	'type'        => 'String',
	'description' => __( 'Meta value.', 'wp-graphql-woocommerce' ),
	'resolve'     => function ( $source ) {
		#return ! empty( $source->value ) ? (string) $source->value : null;
		$value = is_array($source->value) ? json_encode($source->value) : $source->value;
		return ! empty( $source->value ) ? (string) $value : null;
	},
