Sitecore Personalization – Dynamic functionality
In past Quick Start Guides I covered how to get Sitecore Personalization working and how to create dynamic content. This post will outline how to dynamically swap-out components and how Visitor Tags and .NET roles of users can be used to automatically show functionality and content most suited to them.
Update: I have since released this as a Sitecore Marketplace Module for download. Improvements I have made and the full source code are available in this recent blog post
MIME Type Custom Form Validator
I was recently working on methods to validate files uploaded by End Users and the usual recommendation of checking the file extension didn’t sit right with me, even more so when I found out that the .NET API ultimately just checks the File extension as well.
So the product a mornings work I’ve written a decent method of checking those upload files are what they say they are. In this case I created a Custom Sitecore WFFM Field Validator but its simple enough to port the code to custom web forms. Hopefully another dev will find this suitable as an alternative method.
