Image creation via Rest API, including additional data/meta data

[apermo]

When creating a new attachment with the Rest API, that also includes data, normal data like the title will be handled, but additional data, like meta data for example are not handled.

When adding this code near the end of the method create_item() on the file class-wp-rest-attachments-controller.php the issue is solved.

$request->set_url_params( [ 'id' => $id ] );             
                                                               
$response = parent::update_item( $request );             
                                                               
if ( is_wp_error( $response ) ) {                        
        return $response;                                    
}                                                        

I added it prior $fields_update...

Note: Since this requires an upload with data and registered meta, I've added an example file. And you need to register the meta on the website too.

register_meta( 'post', 'my_meta', [
			'type' => 'string',
			'description' => '',
			'single' => true,
			'show_in_rest' => true,
		] );

Thanks for the report @apermo!

I've uploaded a patch to add support for setting meta while creating an attachment. Could you let me know if it fixes your issue?

[TimothyBlynJacobs]

Uploaded an additional patch removing the change to an unrelated test.
