Method Details

`afterMoveInStructure()` public method #

Performs actions after an element is moved within a structure.

public void afterMoveInStructure ( \craft\elements\int $structureId )

$structureId integer The structure ID

`afterSave()` public method #

Performs actions after an element is saved.

public void afterSave ( \craft\elements\bool $isNew )

`$isNew`	boolean	Whether the element is brand new
throws	yii\base\Exception	if reasons

`beforeSave()` public method #

Performs actions before an element is saved.

public boolean beforeSave ( \craft\elements\bool $isNew )

`$isNew`	boolean	Whether the element is brand new
return	boolean	Whether the element should be saved
throws	yii\base\Exception	if reasons

`defineActions()` protected static method #

Defines the available element actions for a given source (if one is provided).

protected static array defineActions ( \craft\elements\string $source = null )

`$source`	string, null	The selected source’s key, if any.
return	array	The available element actions.

`defineDefaultTableAttributes()` protected static method #

Returns the list of table attribute keys that should be shown by default.

protected static string[] defineDefaultTableAttributes ( \craft\elements\string $source )

`$source`	string	The selected source’s key
return	string[]	The table attributes.

`defineSortOptions()` protected static method #

Returns the sort options for the element type.

protected static array defineSortOptions ( )

return	array	The attributes that elements can be sorted by

`defineSources()` protected static method #

Defines the sources that elements of this type may belong to.

protected static array defineSources ( \craft\elements\string $context = null )

`$context`	string, null	The context ('index' or 'modal').
return	array	The sources.

`defineTableAttributes()` protected static method #

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

protected static array defineTableAttributes ( )

return	array	The table attributes.

`displayName()` public static method #

Returns the display name of this class.

public static string displayName ( )

return	string	The display name of this class.

`extraFields()` public method #

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).

public array extraFields ( )

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

`find()` public static method #

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\elements\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);
    }
}

public static craft\elements\db\CategoryQuery find ( )

`getIsEditable()` public method #

Returns whether the current user can edit the element.

public boolean getIsEditable ( )

public static boolean hasContent ( )

return	boolean	Whether elements of this type will be storing any data in the `content` table.

`hasStatuses()` public static method #

public static boolean hasStatuses ( )

return	boolean	Whether elements of this type have statuses.

`hasTitles()` public static method #

Returns whether elements of this type have traditional titles.

public static boolean hasTitles ( )

return	boolean	Whether elements of this type have traditional titles.

`hasUris()` public static method #

Returns whether elements of this type can have their own slugs and URIs.

Note that individual elements must also return a URI format from getUriFormat() if they are to actually get a URI.

public static boolean hasUris ( )

return	boolean	Whether elements of this type can have their own slugs and URIs.

`isLocalized()` public static method #

Returns whether elements of this type store content on a per-site basis.

If this returns true, the element’s getSupportedSites() method will be responsible for defining which sites its content should be stored in.

public static boolean isLocalized ( )

return	boolean	Whether elements of this type store data on a per-site basis.

`refHandle()` public static method #

Returns the handle that should be used to refer to this element type from reference tags.

`route()` protected method #

Returns the route that should be used when the element’s URI is requested.

protected mixed route ( )

return	mixed	The route that the request should use, or null if no special action should be taken

`rules()` public method #

Returns the validation rules for attributes.

Validation rules are used by validate() to check if attribute values are valid. Child classes may override this method to declare different validation rules.

Each rule is an array with the following structure:

[
    ['attribute1', 'attribute2'],
    'validator type',
    'on' => ['scenario1', 'scenario2'],
    //...other parameters...
]

where

attribute list: required, specifies the attributes array to be validated, for single attribute you can pass a string;
validator type: required, specifies the validator to be used. It can be a built-in validator name, a method name of the model class, an anonymous function, or a validator class name.
on: optional, specifies the \craft\elements\scenario array in which the validation rule can be applied. If this option is not set, the rule will apply to all scenarios.
additional name-value pairs can be specified to initialize the corresponding validator properties. Please refer to individual validator class API for possible properties.

A validator can be either an object of a class extending \craft\elements\Validator, or a model class method (called inline validator) that has the following signature:

// $params refers to validation parameters given in the rule
function validatorName($attribute, $params)

In the above $attribute refers to the attribute currently being validated while $params contains an array of validator configuration options such as max in case of string validator. The value of the attribute currently being validated can be accessed as $this->$attribute. Note the $ before attribute; this is taking the value of the variable $attribute and using it as the name of the property to access.

Yii also provides a set of \craft\elements\Validator::builtInValidators. Each one has an alias name which can be used when specifying a validation rule.

Below are some examples:

[
    // built-in "required" validator
    [['username', 'password'], 'required'],
    // built-in "string" validator customized with "min" and "max" properties
    ['username', 'string', 'min' => 3, 'max' => 12],
    // built-in "compare" validator that is used in "register" scenario only
    ['password', 'compare', 'compareAttribute' => 'password2', 'on' => 'register'],
    // an inline validator defined via the "authenticate()" method in the model class
    ['password', 'authenticate', 'on' => 'login'],
    // a validator of class "DateRangeValidator"
    ['dateRange', 'DateRangeValidator'],
];

Note, in order to inherit rules defined in the parent class, a child class needs to merge the parent rules with child rules using functions such as array_merge().
