Products Fields
Products fields allow you to relate products to a parent element.
# Settings
Products fields have the following settings:
- Sources – The product types you want to relate entries from. (Default is “All”.)
- Limit – The maximum number of products that can be related with the field at once. (Default is no limit.)
- Selection Label – The label that should be used on the field’s selection button. (Default is “Add a product”.)
# The Field
Products fields list all of the currently selected products, with a button to select new ones:
Clicking the “Add an entry” button will bring up a modal window where you can find and select additional entries:
# Templating
If you have an element with a Products field in your template, you can access its selected products using its handle:
{% set products = entry.productsFieldHandle %}
That will give you an ElementCriteriaModel object, prepped to output all of the selected products for the given field. In other words, the line above is really just a shortcut for this:
{% set products = craft.commerce.products({
relatedTo: { sourceElement: entry, field: 'productsFieldHandle' },
order: 'sortOrder',
limit: null
}) %}
(See Relations for more info on the relatedTo param.)
# Examples
To check if your Products field has any selected products, you can use the length filter:
{% if entry.productsFieldHandle | length %}
...
{% endif %}
To loop through the selected products, you can treat the field like an array:
{% for product in entry.productsFieldHandle %}
...
{% endfor %}
Rather than typing “entry.productsFieldHandle” every time, you can call it once and set it to another variable:
{% set products = entry.productsFieldHandle %}
{% if products | length %}
<h3>Some great products</h3>
{% for product in products %}
...
{% endfor %}
{% endif %}
You can add parameters to the ElementCriteriaModel object as well:
{% set clothingProducts = entry.productsFieldHandle.type('clothing') %}
If your Products field is only meant to have a single product selected, remember that calling your Products field will still give you the same ElementCriteriaModel, not the selected product. To get the first (and only) product selected, use first()
:
{% set product = entry.productsFieldHandle.first() %}
{% if product %}
...
{% endif %}
