Check if current page is the homepage

Question

I'm trying to run a check within my _layout.html' to remove the navigation bar if the user is on the homepage. I've tried with the following code below, but browsing to a page which is theindex.html` of a Channel breaks the code with the following error:

Variable "entry" does not exist.

This is the code within my _layout.html

{% set handle = entry.section.handle %}
{% if handle == 'homepage' %}
{% else %}
  {% if not craft.app.user.isGuest %}
      {% set users = craft.users %}
      {% include '_navigation'%}
    {% else %}
  {% endif %}
{% endif %}

Answer 1

This works in Craft 3

{% set url = craft.app.request.url %}

{% if url == "/" %}
   homepage
{% endif %}

Answer 2

Our homepage is set via Craft's recommendation:

You can designate any one entry as a site’s homepage using a special home URI.

Since the homepage is an entry, it will always have an entry object with a uri, so I can use a simple one-liner like:

{% set isHomepage = entry is defined and entry.uri == "__home__" ? true : false %}

Answer 3

I'd rather:

{% if entry.uri == "__home__" %}
  🏠
{% endif %}

Answer 4

If using Craft 3.3.6 or later, the best option is probably entry.isHomepage, i.e.

{% if entry is defined and entry.isHomepage %}
   This is the homepage
{% endif %}

Answer 5

To prevent a Twig exception, you may wish to use entry is defined to catch this error.

Another way to detect the homepage would be looking at the request with craft.app.request, something like craft.app.request.pathInfo, if it equals /, then you've got your condition.

Answer 6

Another option for you. Check for the presence of a url segment.

{% if not craft.app.request.segment(1) %}
    This is the homepage
{% endif %}

Answer 7

This works nicely and limits error possiblities:

{% if craft.app.urlManager.matchedElement and craft.app.urlManager.matchedElement.uri == '__home__' %}
    Show on homepage
{% endif %}

Answer 8

My site is localized, so I ended up doing...

{% if craft.app.request.url == '/' or craft.app.request.url == '/' ~ craft.app.language %}
