New Plugin of OJS3: NBN Italia

Hi all,
I made a plugin that contact the Italian NBN resolver and with username e password get an NBN from the server.
It’s the upgrade of the still existing plug in for version 2.0.
I mashed up the working code from the old plugin with code examples taken by URN and DOI plugins.
I think it’s not perfect but it works.
I hope that the developers could have a look to address me for a better code.

There are some things that still do not work well. For example, after the click the link should disappear and be replaced by a SPINNER, so the server response should appear.
But I have no idea how to make it.

The plugin code is on GitHub:

Thanks in advance,


Hi @Alfredo_Cosco,

Excellent, glad to hear about this! Can you point me to the spot in the code that generates the link action you’re having trouble with?

Hello @asmecher,
This is the link before the identifier creation:

Once clicked the link a number is generated by the resolver so if you reload the tab you can assign it:

It would be nice to have:

  1. the link as a button
  2. an ajax switch so you don’t have to reload the page.

The code that creates the link is in the function getLinkActions (line 159 of

            $linkActions = array();
	$request = Application::getRequest();	
	$contextId = $pubObject->getJournalId();
	$objectId = $pubObject->getId();
	// Edit object pub id
	$linkActions['editPubIdLinkActionNBN'] = new LinkAction(
		new AjaxAction(
					array('verb' => 'resolve', 'plugin' => $this->getName(), 'category' => 'pubIds','context'=>$contextId, 'article'=>$objectId)


Hi @Alfredo_Cosco,

You might have to write your own Javascript handler for the page containing the link action in order to get it to do what you want – there are lots of examples of handlers extending AjaxFormHandler that might serve as good templates.
