Tags

You can create folksonomies for your entries, users, and assets using Tags.

# Tag Groups

Before you can create tags, you must create Tag Groups to contain them.

To create a new tag group, go to Settings → Tags and click New Tag Group.

Each tag group holds a unique set of tags, and lets you define a custom set of fields that should be available to tags within the group. However, you don't need to assign any fields to the Tag Group Field Layout in order to use the group.

# Assigning Tags

To assign tags to things (like Entries), you must create a Tags field and add it to a Field Layout.

Each Tags field is connected to a single tag group. Whatever you attach the field to (entries, assets, users, etc.) will be able to create new tags and create relations to any of the tags within that group.

# Querying Tags

You can fetch tags in your templates or PHP code using tag queries.

{# Create a new tag query #}
{% set myTagQuery = craft.tags() %}

Once you’ve created a tag query, you can set parameters on it to narrow down the results, and then execute it by calling .all(). An array of Tag objects will be returned.

See Element Queries to learn about how element queries work.

# Example

We can display a list of the tags in a “Blog Tags” tag group by doing the following:

  1. Create a tag query with craft.tags().
  2. Set the group parameter on it.
  3. Fetch the tags with .all().
  4. Loop through the tags using a for tag to create the list HTML.
{# Create a tag query with the 'group' parameter #}
{% set myTagQuery = craft.tags()
    .group('blogTags') %}

{# Fetch the tags #}
{% set tags = myTagQuery.all() %}

{# Display the tag list #}
<ul>
    {% for tag in tags %}
        <li><a href="{{ url('blog/tags/'~tag.id) }}">{{ tag.title }}</a></li>
    {% endfor %}
</ul>

    .one() %}

This can be combined with fixedOrder if you want the results to be returned in a specific order.

# ignorePlaceholders

Causes the query to return matching tags as they are stored in the database, ignoring matching placeholder elements that were set by craft\services\Elements::setPlaceholderElement().

# inReverse

Causes the query results to be returned in reverse order.

{# Fetch tags in reverse #}
{% set tags = craft.tags()
    .inReverse()
    .all() %}

# limit

Determines the number of tags that should be returned.

{# Fetch up to 10 tags  #}
{% set tags = craft.tags()
    .limit(10)
    .all() %}

# offset

Determines how many tags should be skipped in the results.

{# Fetch all tags except for the first 3 #}
{% set tags = craft.tags()
    .offset(3)

{# Fetch all tags in order of date created #}
{% set tags = craft.tags()
    .orderBy('dateCreated asc')
    .all() %}

# preferSites

If unique is set, this determines which site should be selected when querying multi-site elements.

For example, if element “Foo” exists in Site A and Site B, and element “Bar” exists in Site B and Site C, and this is set to ['c', 'b', 'a'], then Foo will be returned for Site C, and Bar will be returned for Site B.

If this isn’t set, then preference goes to the current site.

{# Fetch unique tags from Site A, or Site B if they don’t exist in Site A #}
{% set tags = craft.tags()
    .site('*')
    .unique()
    .preferSites(['a', 'b'])
    .all() %}

# relatedTo

Narrows the query results to only tags that are related to certain other elements.

See Relations for a full explanation of how to work with this parameter.

{# Fetch all tags that are related to myCategory #}
{% set tags = craft.tags()
    .relatedTo(myCategory)
    .all() %}

Narrows the query results to only tags that match a search query.

See Searching for a full explanation of how to work with this parameter.

{# Get the search query from the 'q' query string param #}
{% set searchQuery = craft.app.request.getQueryParam('q') %}

{# Fetch all tags that match the search query #}
{% set tags = craft.tags()
    .search(searchQuery)
    .all() %}

# site

Determines which site(s) the tags should be queried in.

The current site will be used by default.

Possible values include:

Value Fetches tags…
'foo' from the site with a handle of foo.
['foo', 'bar'] from a site with a handle of foo or bar.
['not', 'foo', 'bar'] not in a site with a handle of foo or bar.
a craft\models\Site object from the site represented by the object.
'*' from any site.

If multiple sites are specified, elements that belong to multiple sites will be returned multiple times. If you only want unique elements to be returned, use unique in conjunction with this.

{# Fetch tags from the Foo site #}
{% set tags = craft.tags()
    .site('foo')
    .all() %}

# siteId

Determines which site(s) the tags should be queried in, per the site’s ID.

The current site will be used by default.

Possible values include:

Value Fetches tags…
1 from the site with an ID of 1.
[1, 2] from a site with an ID of 1 or 2.
['not', 1, 2] not in a site with an ID of 1 or 2.

{# Fetch tags from the site with an ID of 1 #}
{% set tags = craft.tags()
    .siteId(1)
    .all() %}

# title

{# Fetch tags with a title that contains "Foo" #}
{% set tags = craft.tags()
    .title('*Foo*')
    .all() %}

# trashed

Narrows the query results to only tags that have been soft-deleted.

{# Fetch trashed tags #}
{% set tags = craft.tags()
    .trashed()
    .all() %}

# uid

Narrows the query results based on the tags’ UIDs.

{# Fetch the tag by its UID #}
{% set tag = craft.tags()
    .uid('xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx')
    .one() %}

# unique

Determines whether only elements with unique IDs should be returned by the query.

This should be used when querying elements from multiple sites at the same time, if “duplicate” results is not desired.

{# Fetch unique tags across all sites #}
{% set tags = craft.tags()
    .site('*')
    .unique()
    .all() %}

# uri

Narrows the query results based on the tags’ URIs.

['not', '*foo*', '*bar*'] with a URI that doesn’t contain foo or bar.
{# Get the requested URI #}
{% set requestedUri = craft.app.request.getPathInfo() %}

{# Fetch the tag with that URI #}
{% set tag = craft.tags()
    .uri(requestedUri|literal)
    .one() %}

# with

Causes the query to return matching tags eager-loaded with related elements.

See Eager-Loading Elements for a full explanation of how to work with this parameter.

{# Fetch tags eager-loaded with the "Related" field’s relations #}
{% set tags = craft.tags()
    .with(['related'])
    .all() %}
