Interaction observing breaks Westpac & St. George PayWay NET Payment Plugin

Are you using the “Direct Post” integration method in the payment plugin?

Yes. We’re using the older version of the plugin that only supports “Direct Post”

If you’re interested in trying a fix right now, you could paste this chunk of code into akismet-frontend.js right after the line var form = forms[i];, which is line 45 in version 5.0:

var formAction = form.getAttribute( 'action' );

// Ignore forms that POST directly to other domains; these could be things like payment forms.
if ( formAction ) {
	// Check that the form is posting to an external URL, not a path.
	if ( formAction.indexOf( 'http://' ) == 0 || formAction.indexOf( 'https://' ) == 0 ) {
		if ( formAction.indexOf( 'http://' + window.location.hostname + '/' ) != 0 && formAction.indexOf( 'https://' + window.location.hostname + '/' ) != 0 ) {
			continue;
		}
	}
}

That should prevent the interaction observation code from being run on any forms that submit to other sites, like credit card forms. If you try it, can you let me know whether it works for you?

That worked. Will this get patched in the next update? Otherwise I will have to revert back to 4.2.
