# eagerLoadingMap()

Returns an array that maps source-to-target element IDs based on the given sub-property handle.

This method aids in the eager-loading of elements when performing an element query. The returned array should contain the following keys:

  • elementType – the fully qualified class name of the element type that should be eager-loaded
  • map – an array of element ID mappings, where each element is a sub-array with source and target keys.
  • criteria (optional) – Any criteria parameters that should be applied to the element query when fetching the eager-loaded elements.
use craft\db\Query;
use craft\helpers\ArrayHelper;

public static function eagerLoadingMap(array $sourceElements, string $handle) {
    switch ($handle) {
        case 'author':
            $bookIds = ArrayHelper::getColumn($sourceElements, 'id');
            $map = (new Query)
                ->select(['source' => 'id', 'target' => 'authorId'])
                ->from('{{%books}}')
                ->where(['id' => $bookIds)
                ->all();
            return [
                'elementType' => \my\plugin\Author::class,
                'map' => $map,
            ];
        case 'bookClubs':
            $bookIds = ArrayHelper::getColumn($sourceElements, 'id');
            $map = (new Query)
                ->select(['source' => 'bookId', 'target' => 'clubId'])
                ->from('{{%bookclub_books}}')
                ->where(['bookId' => $bookIds)
                ->all();
            return [
                'elementType' => \my\plugin\BookClub::class,
                'map' => $map,
            ];
        default:
            return parent::eagerLoadMap($sourceElements, $handle);
    }
}

View source

Arguments

  • $sourceElements (craft\base\ElementInterface[]) – An array of the source elements
  • $handle (string) – The property handle used to identify which target elements should be included in the map

Returns

array, false, null – The eager-loading element ID mappings, false if no mappings exist, or null if the result should be ignored

# exporters()

Since
3.4.0

Returns the available export options for a given source.

The exporters can be represented by their fully qualified class name, a config array with the class name set to a type key, or by an instantiated element exporter object.

TIP

Element types that extend craft\base\Element should override craft\base\Element::defineExporters() instead of this method.

View source

Arguments

  • $source (string) – The selected source’s key.

Returns

array – The available element exporters.

# fieldLayouts()

Since
3.5.0

Returns all of the field layouts associated with elements from the given source.

This is used to determine which custom fields should be included in the element index sort menu, and other things.

View source

Arguments

  • $source (string) – The selected source’s key

Returns

craft\models\FieldLayout[]

# find()

Creates an craft\elements\db\ElementQueryInterface instance for query purpose.

The returned craft\elements\db\ElementQueryInterface instance can be further customized by calling methods defined in craft\elements\db\ElementQueryInterface before one() or all() is called to return populated craft\base\ElementInterface instances. For example,

// Find the entry whose ID is 5
$entry = Entry::find()->id(5)->one();
// Find all assets and order them by their filename:
$assets = Asset::find()
    ->orderBy('filename')
    ->all();

If you want to define custom criteria parameters for your elements, you can do so by overriding this method and returning a custom query class. For example,

class Product extends Element
{
    public static function find()
    {
        // use ProductQuery instead of the default ElementQuery
        return new ProductQuery(get_called_class());
    }
}

You can also set default criteria parameters on the ElementQuery if you don’t have a need for a custom query class. For example,

class Customer extends ActiveRecord
{
    public static function find()
    {
        return parent::find()->limit(50);
    }
}

View source

Returns

craft\elements\db\ElementQueryInterface – The newly created craft\elements\db\ElementQueryInterface instance.

# findAll()

Returns a list of elements that match the specified ID(s) or a set of element criteria parameters.

The method accepts:

  • an int: query by a single ID value and return an array containing the corresponding element (or an empty array if not found).
  • an array of integers: query by a list of ID values and return the corresponding elements (or an empty array if none was found). Note that an empty array will result in an empty result as it will be interpreted as a search for primary keys and not an empty set of element criteria parameters.
  • an array of name-value pairs: query by a set of parameter values and return an array of elements matching all of them (or an empty array if none was found).

Note that this method will automatically call the all() method and return an array of \craft\base\Element instances. For example,

// find the entries whose ID is 10
$entries = Entry::findAll(10);
// the above code is equivalent to:
$entries = Entry::find()->id(10)->all();
// find the entries whose ID is 10, 11 or 12.
$entries = Entry::findAll([10, 11, 12]);
// the above code is equivalent to:
$entries = Entry::find()->id([10, 11, 12]])->all();
// find users whose email ends in "example.com"
$users = User::findAll(['email' => '*example.com']);
// the above code is equivalent to:
$users = User::find()->email('*example.com')->all();

View source

Arguments

  • $criteria (mixed) – The element ID, an array of IDs, or a set of element criteria parameters

Returns

static[] – An array of Element instances, or an empty array if nothing matches.

# findOne()

Returns a single element instance by a primary key or a set of element criteria parameters.

The method accepts:

  • an int: query by a single ID value and return the corresponding element (or null if not found).
  • an array of name-value pairs: query by a set of parameter values and return the first element matching all of them (or null if not found).

Note that this method will automatically call the one() method and return an \craft\base\Element instance. For example,

// find a single entry whose ID is 10
$entry = Entry::findOne(10);
// the above code is equivalent to:
$entry = Entry::find->id(10)->one();
// find the first user whose email ends in "example.com"
$user = User::findOne(['email' => '*example.com']);
// the above code is equivalent to:
$user = User::find()->email('*example.com')->one();

View source

# searchableAttributes()

Defines which element attributes should be searchable.

This method should return an array of attribute names that can be accessed on your elements. craft\services\Search will call this method when it is indexing keywords for one of your elements, and for each attribute it returns, it will fetch the corresponding property’s value on the element. For example, if your elements have a “color” attribute which you want to be indexed, this method could return:

return ['color'];

Not only will the “color” attribute’s values start getting indexed, but users will also be able to search directly against that attribute’s values using this search syntax:

color:blue

There is no need for this method to worry about the ‘title’ or ‘slug’ attributes, or custom field handles; those are indexed automatically.

TIP

Element types that extend craft\base\Element should override craft\base\Element::defineSearchableAttributes() instead of this method.

View source

Returns

string[] – The element attributes that should be searchable

# sortOptions()

Returns the sort options for the element type.

This method should return an array, where each item is a sub-array with the following keys:

  • label – The sort option label
  • orderBy – An array, comma-delimited string, or a callback function that defines the columns to order the query by. If set to a callback function, the function will be passed a single argument, $dir, set to either SORT_ASC or SORT_DESC, and it should return an array of column names or an yii\db\ExpressionInterface object.
  • attribute (optional) – The table attribute name that this option is associated with (required if orderBy is an array or more than one column name)
  • defaultDir (optional) – The default sort direction that should be used when sorting by this option (set to either asc or desc). Defaults to asc if not specified.
return [
    [
        'label' => Craft::t('app', 'Attribute Label'),
        'orderBy' => 'columnName',
        'attribute' => 'attributeName',
        'defaultDir' => 'asc',
    ],
];

A shorthand syntax is also supported, if there is no corresponding table attribute, or the table attribute has the exact same name as the column.

return [
    'columnName' => Craft::t('app', 'Attribute Label'),
];

Note that this method will only get called once for the entire index; not each time that a new source is selected.

View source

Returns

array – The attributes that elements can be sorted by

# sources()

Returns the source definitions that elements of this type may belong to.

This defines what will show up in the source list on element indexes and element selector modals.

Each item in the array should be set to an array that has the following keys:

  • key – The source’s key. This is the string that will be passed into the $source argument of actions(), indexHtml(), and defaultTableAttributes().
  • label – The human-facing label of the source.
  • badgeCount – The badge count that should be displayed alongside the label. (Optional)
  • sites – An array of site IDs that the source should be shown for, on multi-site element indexes. (Optional; by default the source will be shown for all sites.)
  • criteria – An array of element criteria parameters that the source should use when the source is selected. (Optional)
  • data – An array of data-X attributes that should be set on the source’s <a> tag in the source list’s, HTML, where each key is the name of the attribute (without the “data-” prefix), and each value is the value of the attribute. (Optional)
  • defaultSort – A string identifying the sort attribute that should be selected by default, or an array where the first value identifies the sort attribute, and the second determines which direction to sort by. (Optional)
  • hasThumbs – A bool that defines whether this source supports Thumbs View. (Use your element’s getThumbUrl() method to define your elements’ thumb URL.) (Optional)
  • structureId – The ID of the Structure that contains the elements in this source. If set, Structure View will be available to this source. (Optional)
  • newChildUrl – The URL that should be loaded when a user selects the “New child” menu option on an element in this source while it is in Structure View. (Optional)
  • nested – An array of sources that are nested within this one. Each nested source can have the same keys as top-level sources.

TIP

Element types that extend craft\base\Element should override craft\base\Element::defineSources() instead of this method.

View source

Arguments

  • $context (string, null) – The context ('index' or 'modal').

Returns

array – The sources.

# statuses()

Returns all of the possible statuses that elements of this type may have.

This method will be called when populating the Status menu on element indexes, for element types whose hasStatuses() method returns true. It will also be called when craft\elements\db\ElementQuery is querying for elements, to ensure that its “status” parameter is set to a valid status. It should return an array whose keys are the status values, and values are the human-facing status labels, or an array with the following keys:

  • label – The human-facing status label.
  • color – The status color (green, orange, red, yellow, pink, purple, blue, turquoise, light, grey, black, or white) You can customize the database query condition that should be applied for your custom statuses from craft\elements\db\ElementQuery::statusCondition().

See also hasStatuses() View source

Returns

array

# tableAttributes()

Defines all of the available columns that can be shown in table views.

This method should return an array whose keys map to attribute names and database columns that can be sorted against when querying for elements, and whose values make up the table’s column headers. The first item that this array returns will just identify the database column name, and the table column’s header, but will not have any effect on what shows up in the table’s body. That’s because the first column is reserved for displaying whatever your element’s __toString() method returns. All other items besides the first one will also define which element attribute should be shown within the data cells. (The actual HTML to be shown can be customized with getTableAttributeHtml().)

View source

Returns

array – The table attributes.

# trackChanges()

Since
3.4.0

Returns whether Craft should keep track of attribute and custom field changes made to this element type, including when the last time they were changed, and who was logged-in at the time.
