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
createElement (optional) - an element factory function, which will be passed the element query, the current query result data, and the first source element that the result was eager-loaded for

php

use craft\base\ElementInterface;
use craft\db\Query;

public static function eagerLoadingMap(array $sourceElements, string $handle)
{
    switch ($handle) {
        case 'author':
            $bookIds = array_map(fn(ElementInterface $element) => $element->id, $sourceElements);
            $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 = array_map(fn(ElementInterface $element) => $element->id, $sourceElements);
            $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 (self[]) – An array of the source elements

Returns

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

`extraFields()`

Returns the list of fields that can be expanded further and returned by toArray().

This method is similar to fields() except that the list of fields returned by this method are not returned by default by toArray(). Only when field names to be expanded are explicitly specified when calling toArray(), will their values be exported.

The default implementation returns an empty array.

You may override this method to return a list of expandable fields based on some context information (e.g. the current application user).

View source

Returns

array – The list of expandable field names or field definitions. Please refer to fields() on the format of the return value.

`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,

php

// 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,

php

class Product extends Element
{
    public static function find(): ElementQueryInterface
    {
        // 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,

php

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

View source

If set to a callback function, the function will be passed two arguments: $dir (either SORT_ASC or SORT_DESC) and $db (a craft\db\Connection object), 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)

`tableAttributeHtml()`

Returns the HTML that should be shown for a given attribute in Table View.

This method can be used to completely customize what actually shows up within the table’s body for a given attribute, rather than simply showing the attribute’s raw value.

For example, if your elements have an email attribute that you want to wrap in a mailto: link, your tableAttributeHtml() method could do this:

php

switch ($attribute) {
    case 'email':
        return $this->email ? Html::mailto(Html::encode($this->email)) : '';
    // ...
}
return parent::tableAttributeHtml($attribute);

WARNING

All untrusted text should be passed through craft\helpers\Html::encode() to prevent XSS attacks.

By default the following will be returned:

If the attribute name is link or uri, it will be linked to the front-end URL.
If the attribute is a custom field handle, it will pass the responsibility off to the field type.
If the attribute value is a DateTime object, the date will be formatted with a localized date format.
For anything else, it will output the attribute value as a string.
