Get count of new entries since last visit I'm relatively new to craft, but thanks to this board I am making great progress :-) But here is my first question, which is not answered in here:

I would like to get the count of entries of a certain section, which have been published since the last visit of a user. I'm pretty sure I have to somehow use a cookie for this, but am completely unaware of how to do this in combination with twig :(
You can use the cookies Plugin (or for Craft 2)  to store the value of the timestamp when the users has visited the page for the last time. Or you can create your custom code like explained in the question: How to set a cookie

You can get the current timestamp like it's stated in the docs 

{% set currentTimestamp = now|date('U') %}


And store the cookie like explained

{# Set the cookie using 'set' variable #}
{% do craft.cookies.set( NAME, VALUE, DURATION, PATH, DOMAIN, SECURE, HTTPONLY) %}
{% set yourTimeStamp = getCookie( NAME ) %}


Then you'll search for entries after the specific date

{% set newEntries = craft.entries.postDate('&gt;= ' ~ yourTimeStamp)|length %}
