I am currently working on a WPLMS enhancement for a customer, that allows to simplify the payout of instructor commissions. The whole system runs on the MyCred Points System and students pay for courses with Points. The problem is how to easily payout the instructor commissions via PayPal.
There is currently no addon for MyCred available that does that magic, so I build one myself.
At the moment the payment process via PayPal is completely manual, due to budget constraints. I am basically generating a custom “Send Money” link that prefills the PayPal email and amount to send.
The interface itself handles the payout sessions, tracks the instructor balance, paid and unpaid points.
Here some images to illustrate the admin dashboard:
This list the instructors and their point balance and allows to start the payment process.
Payout sessions make sure, that only one session can be started per instructor, as the instructor could earn new points during the process. The points converted can be changed, allowing you to payout a fixed amount of points.
Its a 3 step process. Login at PayPal. Open the “Send money” dialog and send money to instructor. Confirm that you manually send the money and than register the payment and payout points in the system.
The session can be cancelled at any point. You can also leave the session open and continue at a later point.
On the frontend I added an interface to the BuddyPress Profile, that allows the instructor to track his payouts and balance.
The whole setup could be updated using PayPal Adaptive Payments, to make the whole process completely automated. Something to consider for the future :) Pretty happy with the manual process so far and it will be a great help for my customer to keep track of the commission payouts.
The whole setup is currently targeted for WPLMS, but can easily be adapted to other setups using the MyCred Points System.
“OpenLog is a lightweight front end Javascript plugin (< 1kb gzipped!) that sends your user’s console errors & warnings in real time to a dynamic dashboard built with Node.”
You can not have enough tools to track errors and warnings during development. OpenLog is a nice clean dashboard to keep an overview of things being logged.
It will automatically track console.log, console.info, console.warn and console.error.
You can also use its build in methods.
Javascript Error tracking is becoming more and more important, with applications moving to the client. Many service providers already offer a variety of extensive error tracking solutions for a price. These providers help to get around browser limitations and get the most out of errors.
Depending on your budget, that might not always be an option and not always needed.
To the rescue comes ErrorBoard, that provides a basic interface to track window.onerror events. Requires Node.js, NPM and a free port.
Here the window.onerror, how I set it up for now:

// checks if there was a previously defined window.onerror and preserve it var oldOnError = window.onerror; window.onerror = function( message, url, line, column, error ) { if (errorMsg.indexOf('Script error.') > -1) { return false; } try { var e = encodeURIComponent; var meta = '{"project":"portalzine.de"}'; ( new Image() ).src = 'http://UrltoErrorBoard/error?message=' + e( message ) + '&url=' + e( url ) + '&line=' + e( line ) + '&meta=' + e( meta ) + ( error && error.stack ? '&stack=' + e( error.stack ) : '' ) + ( column ? '&column=' + e( column ) : '' ) ; } catch(e) { // we don't want errors to throw inside onerror } // Call any previously assigned handler if (typeof oldOnError === 'function') { oldOnError.apply(this, arguments); } // returning false triggers the execution of the built-in error handler return false; }; |

var el = document.getElementById('YourElementID'); var e = document.createEvent("MouseEvents"); e.initMouseEvent("click", true, true, window, 0, 0, 0, 0, 0, false, false, false, false, 0, null); el.dispatchEvent(e); |
This often comes up, when you work with jQuery and try to do a simple $(“#YourElementID”).trigger(“click”); or similar.
With inline content being loaded via ajax, you are loosing a lot of interesting usage data. These can be tracked using Google Analytics Events or by sending a Pageview.

(function($) { track = { config:{ pageName : "Your Page", eventSelector : ".trackEvent a, .trackEvent", pageviewSelector : ".trackPage a, .trackPage", }, init : function(){ $("body").delegate(this.config.eventSelector ,"click", function(){ // Navigation / Readmore / Apply / FAQ / Contact / Share var cat = $(this).attr("data-track-cat") || "Navigation"; var action = $(this).attr("data-track-action") || "Click"; var label = $(this).attr("data-track-label") || $(this).text() ; this.sendEvent(cat, action, label); }); $("body").delegate(this.config.pageviewSelector, "click", function(){ var label = $(this).text() +" - "+ this.config.pageName var page = "/"+label.split(' ').join('-').toLowerCase()+"/"; this.sendPageview(page,label); }); }, sendEvent: function(cat, action, label){ ga('send', 'event', { 'eventCategory' : cat , 'eventAction' : action, 'eventLabel' : label, 'eventValue' : 1 }); }, sendPageview : function(page,label){ ga('send', { 'hitType': 'pageview', 'page' : page , 'title' : label }); } }; /* INIT */ track.init(); })(jQuery); |
The above allows to automate tracking by attaching simple classes and use HTML5 data attributes to assign category, action and label. Direct tracking is also possible. Lets split it up :)

$("body").delegate(".trackEvent a, .trackEvent","click", function(){ // Navigation / Readmore / Apply / FAQ / Contact / Share var cat = $(this).attr("data-track-cat") || "Navigation"; var action = $(this).attr("data-track-action") || "Click"; var label = $(this).attr("data-track-label") || $(this).text() ; this.sendEvent(cat, action, label); }); |
This monitors links with the class .trackEVENT attached and fills the event data using HTML5 data attributes. All attributes have default values assigned.
A possible link would look like this:
|
1 |
<a href="#" class=".trackEvent" data-track-cat="Subscribe" data-track-action="View" data-track-label="All my news!">Subscribe to my news!</a> |
The sendEvent function than sends this to Google Analytics.

$("body").delegate(".trackPage a, .trackPage", "click", function(){ var label = $(this).text() +" - "+ this.pageName var page = "/"+label.split(' ').join('-').toLowerCase()+"/"; this.sendPageview(page,label); }); |
Much simpler, this just gets the element text and submits the click as a new Pageview. The label gets the pagename attached and the actual page url is constructed from the label. The sendPageview function than sends this to Google Analytics.

track.sendEvent(cat, action, label); track.sendPageview(page, label); |
Really simple and effective way within a simple OnePager or a bigger web application. BTW I am using delegation to make sure that also links within AJAX content can be tracked.
