Need A Quick CSS Override On Just One Page Via JavaScript?

Found this to work really well for a WordPress custom theme where the only option I had was to drop an override via a header/footer plugin option:

var ref= window.location.pathname;
var search="/youruniquepagelink/";
if (ref.indexOf(search) > -1) {
let myElements = document.querySelectorAll(".your-class");
for (let i = 0; i < myElements.length; i++) {
	myElements[i].style.display = "none";

Sitecore Error (SOLVED): An item name cannot contain any of the following characters: \/:?”\-|[] (controlled by the setting InvalidItemNameChars)

You may have ran into an issue during deployments when trying to publish in the past where you have seen this message:

“An item name cannot contain any of the following characters: \/:?”<>\-|[] (controlled by the setting InvalidItemNameChars)”

In order to help move forward on this you need to disable the default ItemNameValidation settings if you are having some deployment issues.

To do that (would only recommend temporarily) you can follow the steps below:

Add a config file to App_Config/Include named z.DisableItemNameValidation.config and put this in it:

<configuration xmlns:patch="">
      <setting name="ItemNameValidation">
        <patch:attribute name="value"></patch:attribute>

Again, when you are finished I would recommend taking this back out of your files to keep things as standard as possible.

HTML, Intercom, JavaScript, Web, Wordpress

So You Only Want Intercom Chat On Certain Pages In WordPress? Here’s How!

So I had a client want to use Intercom. Great! So I went to Intercom and signed up for an account, then went to our WordPress instance and downloaded the Intercom for WordPress plugin. Everybody wins! Until…I get the requirement after the fact that the client does not want the chat pop up on every page…but only on certain pages. However, the out of the box Intercom for WordPress plugin is only built to be supported for all pages and not some. What to do…what to do…let’s figure it out.

First, login into your WordPress (.org version) as an admin and uninstall the Intercom for WordPress plugin. Next install the Head, Footer and Post Injections Plugin:

Once installed, go to the Head, Footer and Post Injections plugin settings and insert the following script injection into the Desktop and Mobile (Check the Mobile checkbox) BEFORE THE CLOSING TAG (FOOTER). 

var ref1= window.location.pathname;
var search1 = "/pagepath1/";
var search2 = "/pagepath2/"; 
if (ref1.indexOf(search1) > -1 || ref1.indexOf(search2) > -1)
  window.intercomSettings = {
    app_id: "YourIntercomID"
<script>(function(){var w=window;var ic=w.Intercom;if(typeof ic==="function"){ic('reattach_activator');ic('update',intercomSettings);}else{var d=document;var i=function(){i.c(arguments)};i.q=[];i.c=function(args){i.q.push(args)};w.Intercom=i;function l(){var s=d.createElement('script');s.type='text/javascript';s.async=true;s.src='';var x=d.getElementsByTagName('script')[0];x.parentNode.insertBefore(s,x);}if(w.attachEvent){w.attachEvent('onload',l);}else{w.addEventListener('load',l,false);}}})()</script>

Save the plugin settings. This JavaScript will check on the specified page paths and only execute turning on Intercom for the specific page paths. Hope this helps!

.Net MVC – Display a user’s Full Name instead of User.Identity.Name (DOMAIN\USERNAME)

I had a request come in on a MVC web app to display a user’s full name instead of their domain network username. The app was using something like:

<p>Hello, @User.Identity.Name</p>

which displayed like:

Hello, MYDOMAIN\myusername!

So to update this on the MVC web app (and avoid a dedicated helper) here is what I did:

In your _ViewImports.cshtml include:

@using System.DirectoryServices.AccountManagement

Then, in your _Layouts.cshtml place this

    var context = new PrincipalContext(ContextType.Domain);
    var principal = UserPrincipal.FindByIdentity(context, User.Identity.Name);

The above will render the user’s currently logged in claims and return their claim attributes as needed. You can use others as you have them also for other purposes, too.

Now, in your _Layouts.cshtml you can switch your original hello item to:

<p>Hello, @principal.GivenName @principal.Surname!</p>

You should get a friendlier format like:

Hello, Jared Meredith!

Hope that helps. Questions or comments are always welcome!

Check For Internet Explorer (IE) Compatibility Mode

Create a JavaScript file called iecheck.js and paste the following in the snippet:

function trueOrFalse() {
 return true;

function IeVersion() {
 // Set defaults
 var value = {
 IsIE: false,
 TrueVersion: 0,
 ActingVersion: 0,
 CompatibilityMode: false

// Try to find the Trident version number
 var trident = navigator.userAgent.match(/Trident\/(\d+)/);
 if (trident) {
 value.IsIE = true;
 //Convert from the Trident version number to the IE version number
 value.TrueVersion = parseInt(trident[1], 10) + 4;

// Try to find the MSIE number
 var msie = navigator.userAgent.match(/MSIE (\d+)/);
 if (msie) {
 value.IsIE = true;
 // Find the IE version number from the user agent string
 value.ActingVersion = parseInt(msie[1]);
 } else {
 // Must be IE 11 in "edge" mode
 value.ActingVersion = value.TrueVersion;

// If we have both a Trident and MSIE version number, see if they're different
 if (value.IsIE &amp;&amp; value.TrueVersion &gt; 0 &amp;&amp; value.ActingVersion &gt; 0) {
 // In compatibility mode if the trident number doesn't match up with the MSIE number
 value.CompatibilityMode = value.TrueVersion != value.ActingVersion;
 return value;

Once you have the JavaScript file then open your page where you are going to check for compatibility for and place a reference to the iecheck.js file in the head tag.

<script src="iecheck.js" type="text/javascript"></script>

After that you have multiple options on how to use the script.

For example, if you would like to check for compatibility and redirect then paste the following snippet inside of the body of your html:

<script type="text/javascript">
// 0 = not in compatibility view, 1 = in compatibility view
var ie = IeVersion();
if ((ie.CompatibilityMode == "0") && (ie.IsIE == "1")) {
window.location = "redirecttosomewhere.html"
else {
// do nothing, is in compatibility view

Another example would be if you just want to see the results on the page; just place this snippet inside of the body of your html:

<script type="text/javascript">
// <![CDATA[
var ie = IeVersion();
document.write("IsIE: " + ie.IsIE + "</br>");
document.write("TrueVersion: " + ie.TrueVersion + "</br>");
document.write("ActingVersion: " + ie.ActingVersion + "</br>");
document.write("CompatibilityMode: " + ie.CompatibilityMode + "</br>");
// ]]>

Hope this helps. Questions are always welcome.
