Loop through fields in field layout when `entry` is not set

Question

Is there a way in a template to loop through the fields in a field layout without having to tie them to an entry? I'm currently grabbing that list with entry.getFieldLayout(3).getFields(), but that only works when entry is set.

Answer 1

This can be done by reaching through the section and entry type to the final field layout. Like this:

{% set section = craft.sections.getSectionByHandle('sectionName') %}
{% set entryType = '' %}
{% for type in section.getEntryTypes %}
    {% if type.handle == 'entryType' %}
        {% set entryType = type %}
    {% endif %}
{% endfor %}
{% set fieldLayout = craft.fields.getLayoutById(entryType.fieldLayoutId) %}

You should be abel to use getFields as normal.
