All tag fields Location relations Query Type

This Query Type is used to build queries that fetch Locations with Content tag field relations from all tag fields of a given Content.

Hint

Tag field Content relations are Content items tagged with a tag contained in the tag fields of a given Content.

Note

Only visible main Locations of the related Content will be used.

Hint

This query type assumes Netgen’s TagsBundle is used for tagging functionality.

Examples

On full view for product type Content fetch all Locations with Content of type article that is tagged with any of the tags from the given product. Sort them by name and paginate them by 10 per page using URL query parameter page:

ezpublish:
    system:
        frontend_group:
            ngcontent_view:
                full:
                    product:
                        template: '@ezdesign/content/full/product.html.twig'
                        match:
                            Identifier\ContentType: product
                        queries:
                            related_articles:
                                query_type: SiteAPI:Location/Relations/AllTagFields
                                max_per_page: 10
                                page: '@=queryParam("page", 1)'
                                parameters:
                                    content_type: article
                                    sort: name
{% set articles = ng_query( 'related_articles' ) %}

<h3>Related articles</h3>

<ul>
{% for article in articles %}
    <li>{{ article.content.name }}</li>
{% endfor %}
</ul>

{{ pagerfanta( articles, 'twitter_bootstrap' ) }}

Own conditions

content

Defines the source (from) relation Content, which is the one containing tag fields.

Note

This condition is required. It’s also automatically set to the Content instance resolved by the view builder if the query is defined in the view builder configuration.

  • value type: Content
  • value format: single
  • operators: none
  • target: none
  • required: true
  • default: not defined

Examples:

# this is also automatically set when using from view builder configuration
content: '@=content'
# fetch relations from Content's main Location parent Location's Content
content: '@=content.mainLocation.parent.content'
# fetch relations from Content's main Location parent Location's parent Location's Content
content: '@=content.mainLocation.parent.parent.content'

exclude_self

Defines whether to include Content defined by the content condition in the result set. If null is used as a value, the condition won’t be added.

  • value type: boolean, null
  • value format: single
  • operators: none
  • target: none
  • required: false
  • default: true

Examples:

# do not include the source relation Content, this is also the default behaviour
exclude_self: true
# include the source relation Content
exclude_self: false

Inherited Location conditions

main

Defines whether returned Locations are main Locations or not. Use true to get main Locations (which is also the default behaviour), false to get non-main Locations and null to get both.

  • value type: boolean, null
  • value format: single
  • operators: eq
  • target: none
  • required: false
  • default: true

Examples:

# identical to the example below
main: true
main:
    eq: true
# get both main and non-main Locations
main: ~

priority

Defines the priority of the Location. If null is used as a value, the condition won’t be added.

  • value type: integer, null
  • value format: single
  • operators: gt, gte, lt, lte, between
  • target: none
  • required: false
  • default: not defined

Examples:

# multiple operators are combined with logical AND
depth:
    gt: 4
    lte: 8
depth:
    between: [4, 7]

visible

Defines whether returned Locations are main Locations or not. Use true to get main Locations (which is also the default behaviour), false to get non-main Locations and null to get both.

  • value type: boolean, null
  • value format: single
  • operators: eq
  • target: none
  • required: false
  • default: true

Examples:

# identical to the example below
visible: false
visible:

# get both visible and hidden or invisible Locations
visible: ~

is_field_empty

Defines conditions on whether the Content fields are empty or not. If null is used as a value, the condition won’t be added.

Common query parameters

limit

Defines the maximum number of items to return. If null is used as a value, the limit will be set to the default value.

Note

This parameter will not be used if you execute the query from Twig using ng_query function. In that case Pargerfanta pager is used with semantic parameters page and max_per_page. To execute the query directly use ng_raw_query Twig function instead.

  • value type: integer, null
  • value format: single
  • required: false
  • default: 25

Examples:

limit: 10

offset

Defines the offset for search hits, used for paging the results. If null is used as a value, the offset will be set to the default value.

Note

This parameter will not be used if you execute the query from Twig using ng_query function. In that case Pargerfanta pager is used with semantic parameters page and max_per_page. To execute the query directly use ng_raw_query Twig function instead.

  • value type: integer, null
  • value format: single
  • required: false
  • default: 0

Examples:

offset: 20

sort

  • value type: string, SortClause, Location
  • value format: single, array
  • required: false
  • default: not defined

Here you can use any SortClause implementation or a Site API Location object. Using a Location object is the same a using sort clauses that are defined on it:

sort: "@=location"

The example above is a shortcut to the example below:

sort: "@=location.innerLocation.getSortClauses()"

If you define your query in the view configuration, you won’t be able to directly instantiate a SortClause there. For that reason we provide a way to define the sort clause as a string instead. With this format a subset of commonly used SortClauses is supported. Sort direction is defined as asc for ascending and desc for descending. In can be omitted, in which case it will default to asc.

Strings can be used to define multiple sort clauses through an array of definitions:

sort:
    - depth asc
    - modified desc

Following sort clauses are available through string definition:

Location depth

String depth enables sorting by Location’s depth:

sort: depth
sort: depth asc
sort: depth desc

Content Field

String in form of of field/[content_type]/[field] enables sorting by any Content Field. For example by Field with identifier title in ContentType with identifier article:

sort: field/article/title
sort: field/article/title asc
sort: field/article/title desc

Content modification date

String modified enables sorting by the Content modification date:

sort: modified
sort: modified asc
sort: modified desc

Content name

String name enables sorting by the Content name:

sort: name
sort: name asc
sort: name desc

Location priority

String priority enables sorting by the Location priority:

sort: priority
sort: priority asc
sort: priority desc

Content publication date

String published enables sorting by the Content publication/creation date:

sort: published
sort: published asc
sort: published desc
