The Public Knowledge for Mobile, Web and Facebook works well enough, but it is coded badly and is really difficult to customise.
I HAVE to get to the bottom of this because I have to get a developer to make it able to be multi-branded. Here is my documentation on unpacking this beast to see how it works.

This may not make any sense to you, but it is has definitely helped me to understand the structure of the PKB app and it is a cheat sheet of where to go to change things when I need to. |
Overview
I love the PKB App, but I need some additional features - notably multiple branding. It can look and function exactly like PKB2 but if it looks nicer that would be great. I need
- Multi Language
- Multiple brands
- Faceted Search
- Share this (just print and email)
- A better support ticket function (nicer looking, more questions)
I don't need
- Deflection
Most importantly it needs to be able to be used with the ServiceCloud share Knowledge Article via URL feature https://help.salesforce.com/ap ex/HTViewSolution?urlname=Know ledge-One-widget-Share-an-arti cle-as-a-URL-Email-an-article- as-a-PDF-unavailable&language= en_US
Structure
Pages
- pkb_Home VF Page is the first page that is called when the visitor comes to the site. This is set up in the Sites settings as the Active Site Home Page. It is not visible in the URL as the Path as defined in the sites is shown only. eg xxxx.force.com/mykb is xxxx.force.com/mykb/pkb_Home
- All this page does is call pkb_Template
- and sets the controller as pkb_Controller
- and gets the Language from the URL
- Structure
- Apex
- Turn off all SF look
- standardStylesheets="false"
- showHeader="false"
- sidebar="false"
- Controllers
- Extension - pkb_Controller
- Parameters
- language = CurrentPage.parameters.1
- Composition
- Turn off all SF look
- Apex
- The Good
- There is no CSS in this page.
- Notes
- Create your own Home Page name and set the Active Site Home Page in Sites to the new Home page - eg just Home rather than pkb_Home might be nicer.
- But for brands have brandXhome and brandyhome pages
- Create your own Home Page name and set the Active Site Home Page in Sites to the new Home page - eg just Home rather than pkb_Home might be nicer.
- pkb_Home_fb the Facebook Home page - I'm ignoring this at the moment.
- pkb_Template the main HTML layout of the page that is displayed when the visitor first sees your site - this is probably going to be the main page you customise.
- Notes
- Controller - controls everything coming out of Salesforce
- Javascript - sets some parameters
- CSS - is everywhere
- theKad - the variable name for the actual Data of the Article. This comes from the Controller

- Javascript to prepare to render the overlay - calls a function
- Something in here also for Javascript function to hideImmediateHelp - I still have not worked this one out.
- If Header info is shown
- pkb_article - this is the main HTML for viewing the article summary in a list - this is only called from Component - pkb_results. I would not do too much customisation to this, unless you have different fields you need to display from your article types.
- Parameters (Attributes)
- Article ID
- Title
Summary - URL Name
- Article Type Name
- Article Type Label
- Last Modified Date

- nonSiteArticleURL - the ID of the Article for if this is displayed from inside Salesforce.
- articleURL - sets up if it should display the site or non site URL
- Div Article - displays the Title with the URL to the Article - uses the Variables articleURL and params to work out the correct URL

- Summary - only shows the first 255 chars then a ...
- Div Data - displays the Article Type Label and the firstPublishedDate - eg my Article type is Knowlege 15 May 2001
- Parameters (Attributes)
- pkb_articleview - this is the main article HTML. It's probably not wise to change this much - have the background of the article distinguished from the rest of the site.
- Parameters (Attributes)
- The controller
- showFeedbackYesNo
- showBackLinks
- Add an Attribute for what the Breadcrumbs should display as for each site
- Sets variable for pageNum
- Div
- inline styles for margin
- Div - Class = articleViewIcons - shows the share this icons
- Component - pkb_articleicons
- Div Backlinks - sets up the backlinks and breadcrumbs
- Dependant upon the toggle for displaySearchResultsLink in the controller
- Div id = articleContainer
- Inline styles for width
Info OK, here is the crux of the whole thing - it uses an <apex:insert tag to insert the body of the article in here.
Insert seems to be like an include page. Now to find out where the body is defined... I have no idea.
- Output panel with inline sytels for margins
- Weird code to not display the article content if you are displaying through standard apex - weird.
- Shows component pkb_related only if it's facebook - WHY?
- Shows component pkb_feedbackyesno if showFeedbackYesNo is true
- Replace this with a 5 star rating
- Parameters (Attributes)
- pkb_articleicons - the Share This icons - all call a JS source or URL or even iFrame - now, calling an external javascript from a Salesforce page is not allowed is it?
- Div
- inline CSS
- Google Plus
- not needed anymore
- Facebook
- get rid of it - you are a business, not promoting scandals on Facebook.
- RSS
- may be useful if you have RSS on the rest of your site. Otherwise delete it.
- Twitter
- Only if you are really strong on monitoring your twitter otherwise it HAS to go.
- Print
- Yeah, probably keep it
- Email
- It just sends a URL to the article - not very useful
- Yep, keep it.
- Div
Javascript
- pkb_js
- Notes
- This javascript is displayed in full view on a PKB site - you can copy all the javascript that another site using PKB has modified.
- takes parameter (attribute) of the controller
- Change this to also take the parameter of the home page
- Has JQuery
- Has JQuery to detect if the browser is a mobile device.
- Remove this when making your HTML responsive
- Sets some variables - these are captured from the Apex controller and stored in JS variables so the javascript can use it - noted only important ones.
- baseURL - pkbCon.currentSiteURL
- currLanguage - pkbCon.SelectedLanguage
- contactUS - pkbCon.displayContactUs
- viewingArticle - pkbConViewingArticle
- pkbHome -
"{!IF(pkbCon.facebook,$Page.pkb_Home_fb,$Page.pkb_Home)}";
Nope, you don't want this, you don't need Facebook - you want the home page passed in from the template
- Functions
- These are well documented.
- searchButtonClicked
- Displays the error message from custom label - PKB2_js_search_string_length when there is less than 3 chars entered.
- There are some functions to
- toggle when feedback is displayed
- show or hide featured articles
- show or hide the contact form
- To adjust the height of the right column.
- Notes
Controller
- Terms
- KAD = KnowledgeArticleData
- KAV = KnowledgeArticleVersion
- This is the interface between the Salesforce data and the HTML
- It does all the queries and the logic
- Do not mess around with this - you will break things
- Definitely do not change anything that comes from CUSTOM SETTINGS
- Some things you may want to change.
- // populate the case data
- To add extra fields to the Case
- Also look at the CONTACT US FOR WRAPPER CLASS
- // attempt to create the account and contact if configured to do so
- To add extra Contact and Account fields
- // send email only if siteAdmin isn't null
- To send the Case email with different fields
- // populate the case data
Still to do:
- Where does the body of the article display come from
- How does the language work
- Where to pass in the site name

- A YouTube video
- The guide
- A really nice step by step guide

To Change CSS
All the various places there may be CSS
- Template - footer
- Template - header - left and right
- Every single component
- The CSS file of course
(Also see the note about the Important Tag)
Language
I still can't work out the language translation of the label - in the controller it says it comes from the standard user Locale picklist, but where is the translation for that stored (not in ObjectTranslations - USer-zh_CN.objectTranslation file only has custom fields
The value in the dropdown box is zh_CN but the text is 中国的 which google translates to China's or China and Of - this is not good. And our chinese language translator is not happy with it.
Hm, maybe it is not even a Salesfore thing as this seems to be about Javascript generally.
Maybe I will have to hard code it? Nooooo!
