Conditional Logic Feature?

Can you add it as an issue (feature request) on Github?

You could write a hook on on Forms3rdPartyIntegration_use_form and inspect the $form argument, then return false on your condition.

Or you could hook to Forms3rdPartyIntegration_service_filter_args later down and set response_bypass so it skips over the post. You’d have access to already transformed submission by then.

I think something like:

add_filter('Forms3rdPartyIntegration_service_filter_args', 'forms3rdparty_conditional_send', 10, 3);

function forms3rdparty_conditional_send($post_args, $service, $form) {
    // inspect transformed submission body for presence/lack/value of the desired value
    if( !isset($post_args['body']['my-conditional-field']) ) {
        // set plugin bypass -- will treat this as though it had sent the submission; we don't want the plugin to think it failed
        $post_args['response_bypass'] = array('body' => 'OKAY'); // essentially a success placeholder
    }

    return $post_args;
}

Ahh jeez…my mistake.

I forgot that the response_bypass should return a response that looks just like a real wp_post response — see source line https://github.com/zaus/forms-3rdparty-integration/blob/master/forms-3rdparty-integration.php#L507

You’re probably getting a ‘physical request failure’ message, right? The function should instead return:

$post_args['response_bypass'] = array('body' => 'OKAY', 'response' => array('code' => 200));
