Sitecore 9 Forms: The required anti-forgery cookie __requestVerificationToken is not present

Have you submitted a form and it returned with this error ‘The required anti-forgery cookie “__requestVerificationToken” is not present’? If so, here is the resolution.

  • This could be because of caching. Can you check if your rendering component or container/page level caching check box is checked? if so, unchecking the caching will fix the issue.
  • Also here is quick check you can do to see whether your form is cached – Inspect the form and check the _requestverificationtoken value like below and refresh the page – do you see same value now? if so, your form is in cache!
 <input name="__RequestVerificationToken" type="hidden" value="O0P3KYBqgEZXlksWnY3fhu0PptEB0a47rRGMgHNnF6lIL2S8tcts9z9NxdxIum7ANKMv95FZB275AeLTw6WxcOl4jCQ1">

Install Sitecore 9.1 quickly in 5 easy steps

Image result for install software

I’m participating in Sitecore Hackathon for the first time this year. One of the requirement is to have sitecore 9.1(Initial version) installed on your machine. So I want to share my experience how i quickly installed Sitecore 9.1 using SIF on developer machine in 5 easy steps. This post includes the prerequisites, preparation and installation.

Prerequisites:

  • OS: Windows 10, Windows Server 2016
  • DB:
    • Microsoft SQL Server 2017 or 2016 SP2 – Supports the XM database and is the required for the xDB
    • Microsoft SQL Server 2014 Sp2 – Only supports XM databases and does not support the xDB
    • MongoDB Server 3.6.6 – This is required if you are going to use MongoDB for the Collection database or as a Session State Provider
  • IIS 10
  • . NET
    • Sitecore XP 9.1.0 requires .NET Framework 4.7.1
    • Sitecore Identity server requires .NET Core Runtime 2.1.3
    • You must apply any available updates to the .NET Framework on every Sitecore installation
  • Search Indexing
    • Solr 7.2.1 – Default search provider
    • Azure Search – supported and recommended for Azure Cloud PaaS deployments only
    • Lucene – Only supports content search and does not support xConnect.
  • Powershell 5.1 – for Installing SIF

Preparation:

  • Download installation package(XP Single) from here
  • Extract the zip file you just downloaded
  • Again extract this file – XP0 Configuration files 9.1.0 rev. 001564.zip
  • Copy your license.xml file (If you have enrolled for Hackathon, you should have received the file in email)

Now let’s begin the installation!

Step 1: Solr 7.2.1 Install

Check out Jeremy Davis’s low effort Solr installs. It’s pretty cool! https://jermdavis.wordpress.com/2017/10/30/low-effort-solr-installs/

If you want to take traditional approach(Install as service using NSSM tool), here are the steps

  • Download Solr from here
  • Install as service using NSSM tool

  • It opens the NSSM Service Installer like below. Fill out the fields.
  • Note: If you already another version of solr running, make sure to give different port name.
Solr 5 running as a service on Microsoft Windows

Step 2: Install SIF

Run the following scripts in Powershell as administrator.

Register-PSRepository -Name SitecoreGallery -SourceLocation https://sitecore.myget.org/F/sc-powershell/api/v2;
Install-Module SitecoreInstallFramework;
Install-Module SitecoreFundamentals;
Update-Module SitecoreInstallFramework;
Update-Module SitecoreFundamentals;
Import-Module SitecoreFundamentals -Force;
Import-Module SitecoreInstallFramework -Force;

Step 3: Update config files

Update the following files in the folder with the exact information – solr path, solr service name, configsets path, instance name for sitecore, SQL instance name and login credentials.

  • XP0-SingleDeveloper.ps1
  • XP0-SingleDeveloper.json
  • xconnect-solr.json
  • sitecore-solr.json

Step 4: Install prerequisites

Install-SitecoreConfiguration -Path .\Prerequisites.json

Step 5: Install Sitecore 9.1

  • Execute the script ./XP0-SingleDeveloper.ps1 (takes good amount of time to execute)
  • Fingers crossed!

Note: There is no ‘b’ admin password. You can get the password at the end of the script execution. Nice work Sitecore!

Notice that it installed the third site in IIS – Identity Server (New to 9.1)

Also noticed the http://[sitename]/sitecore/login now redictes to identiyserver in the URL.

Have fun exploring Sitecore 9.1!

Sitecore Certification : Exam and Review

I recently took the Sitecore 9.0 Certified Platform Associate Developer exam online and passed with an overall score of 88%.

Here are the steps I have taken to become certified:

  • Took the Developer’s Fundamental Collection online. You can also do it through Instructor-Led or Virtual Classroom options – https://learning.sitecore.com/#homepage-learning-solutions
  • Went through all the modules and lab exercises. When I completed the fifth module, I received an access key in the email to book the exam.
  • You can book the exam in-person in the center or online. I chose online and booked the exam via https://www.webassessor.com/sitecore/index.html
  • This is a proctor guided exam, no book allowed. Also, the exam software Senitel says you should have an external web camera. It worked with the in-built camera on my work computer. So don’t worry about the external camera.
  • The exam has 50 questions and 90 minutes to complete. You can review the answers as many times as you want. I completed the exam in 30 minutes and review the answers in the next 30 minutes and I still have 30 more minutes left!
  • Overall I got a 88% score. Here is my Topic level scoring:

Architecture: 100%
Creating and Editing Items: 100%
Development Environment: 75%
Docs and Support: 100%
Installation: 100%
Publishing: 100%
xManagement: 100%
Field Types: 83%
Media: 100%
Templates: 85%
Versioning: 100%
Presentation: 77%
API: 100%

  • Once you complete you exam, you will receive an email from test center with score and certification pdf file. Good luck!

Tips and Tricks : GIT Cherry Pick

I came across a situation where I need to merge only couple of commits from branch(not the entire branch) and Git cherry pick does the job pretty clean. I use Git extensions IDE and context menu makes it easier.

Here are the steps:

  • Make sure you checkout the branch you want to merge the commits
  • Navigate to the commit you want to cherry pick
  • Right click and select cherry pick commit option

  • It opens a dialog with the option to choose auto commit and add commit reference. I recommend checking both of them. By default, they are not checked. Hit Cherry pick button.
  • Now the commit is auto committed and ready to be pushed into current branch.

Happy cherry picking!

Sitecore 9 Forms: Custom Submit Action

One of most common scenario I came across in Sitecore 9 Form is to create your custom submit action. You can achieve this in three simple steps.

Here is a video of how to create Custom Submit Action.

Step 1: Create submit action button in Sitecore

Create the custom action button under /sitecore/system/Settings/Forms/Submit Actions.

Step 2: Create code behind class

Create a class that inherits SubmitActionBase class and override the Execute method.

public class CustomSubmitAction : SubmitActionBase<string>
{
public CustomSubmitAction(ISubmitActionData submitActionData) : base(submitActionData)
{
}

public override void ExecuteAction(FormSubmitContext formSubmitContext, string parameters)
{
Assert.ArgumentNotNull((object)formSubmitContext, nameof(formSubmitContext));

if (this.TryParse(parameters, out string target))
{
try
{
if (this.Execute(target, formSubmitContext))
return;
}
catch (ArgumentNullException ex)
{
}
}
formSubmitContext.Errors.Add(new FormActionError()
{
ErrorMessage = this.SubmitActionData.ErrorMessage
});
}

protected override bool Execute(string data, FormSubmitContext formSubmitContext)
{
Assert.ArgumentNotNull(data, nameof(data));
Assert.ArgumentNotNull(formSubmitContext, nameof(formSubmitContext));

//Prepare model here
var model = new EmailModel()
{
Email = GetValue(formSubmitContext.Fields.FirstOrDefault(f => f.Name.Equals("EmailAddress")))
};

// Call any API service call

return true;
}

private static string GetValue(object field)
{
return field?.GetType().GetProperty("Value")?.GetValue(field, null)?.ToString() ?? string.Empty;
}

protected override bool TryParse(string value, out string target)
{
target = string.Empty;
return true;
}

Step 3: Set the custom submit action fields

Update the ModelType and Error Message on the button shown below.

Bind the custom submit action to Submit button like below.

Publish the button. The submit button on form should now trigger the custom save action! Any questions, let me know.

Happy sitecoring.

Sitecore 9 Forms: Success message


Sitecore 9 form feature is awesome and simple to work with. It is more like Visual Studio Toolbox and you can drag and drop the fields.

I had a requirement from Client asking for Ajax form and wanted to show Confirmation/Success message after the form is submitted. Out of the box, this is achievable with the Form.

Here is a small guide on how to create a form with confirmation message:

1. Select Forms from Dashboard.

2. Click Create button.
3. Select blank form.

4. Drag a page for main content.
5. Drag a another page for confirmation message.
6. Design the fields according to needs. Here I’m doing Email Signup form. You can add field validation and css-class as needed.

Please make sure you have these scripts in Layout.cshtml.

@Html.RenderFormStyles()
@Html.RenderFormScripts()

7. On the submit button, set the Navigation step to Next instead of submit. This does the trick to show the confirmation page.

7. Save the form.
8. Now you can see the form in Content Editor.

Don’t forget to publish the form and place it on a web page under MVC layout. Here is Sitecore documentation on Adding a form to webpage.

Happy Sitecoring.

Pattern Matching in C# 7.0 Switch Statements

I was trying to figure out what would be the best way to list out partial views based on Model type and found C# 7.0 new feature ‘Pattern matching in switch statements’ would be great fit for the scenario.

Before only string/integer can be compared, now you can compare on any type of object. Below is the example shows switch case based on Model Interface type.

@model Synthesis.IStandardTemplateItem

@switch (Model)
{
case INavigationColumnItem nci:
//Take any action
break;
case IColumnNavigationFolderItem ncfi:
//Take any action
break;
case IHeaderLogoItem hli:
//Take any action
break;
case IHeaderNavigationLinkItem hnli:
//Take any action
break;
case IHeaderPhoneNumberItem hpni:
//Take any action
break;
}

Checkout more cool new C# 7.0 features here. Happy coding.
