Arguments

$columns (string, array, yii\db\ExpressionInterface) – The columns (and the directions) to be ordered by. Columns can be specified in either a string (e.g. "id ASC, name DESC") or an array (e.g. ['id' => SORT_ASC, 'name' => SORT_DESC]).

The method will automatically quote the column names unless a column contains some parenthesis (which means the column contains a DB expression).

Note that if your order-by is an expression containing commas, you should always use an array to represent the order-by information. Otherwise, the method will not be able to correctly determine the order-by columns.

Since version 2.0.7, an yii\db\ExpressionInterface object can be passed to specify the ORDER BY part explicitly in plain SQL.

`fields()`

Returns the list of fields that should be returned by default by toArray() when no specific fields are specified.

A field is a named element in the returned array by toArray(). This method should return an array of field names or field definitions.

If the latter, the array key should be the field name while the array value should be the corresponding field definition which can be either an object property name or a PHP callable returning the corresponding field value. The signature of the callable should be:

php

function ($model, $field) {
    // return field value
}

For example, the following code declares four fields:

email: the field name is the same as the property name email;
firstName and lastName: the field names are firstName and lastName, and their values are obtained from the first_name and last_name properties;
fullName: the field name is fullName. Its value is obtained by concatenating first_name and last_name.

php

return [
    'email',
    'firstName' => 'first_name',
    'lastName' => 'last_name',
    'fullName' => function ($model) {

  .positionedBefore({myElement})
  .all() %}

`preferSites()`

Since: 3.2.0

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 B, and Bar will be returned for Site C.

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

customFields()	Returns the fields that should take part in an upcoming elements query.
extractFieldsFor()	Extract nested fields from a fields collection for a given root field Nested fields are separated with dots (.). e.g: "item.id" The previous example would extract "id".

filterCondition()	Removes empty operands from the given query condition.
getUnaliasedColumnsFromSelect()
getUniqueColumns()	Returns unique column names excluding duplicates.
isEmpty()	Returns a value indicating whether the give value is "empty".

resolveFields()	Determines which fields can be returned by toArray().
setCommandCache()	Sets $command cache, if this query has enabled caching.

`afterPrepare()`

This method is called at the end of preparing an element query for the query builder.

It is called at the beginning of prepare(), right after query and subQuery have been created.

Returns

boolean – Whether the query should be prepared and returned to the query builder. If false, the query will be cancelled and no results will be returned.

`beforePrepare()`

This method is called at the beginning of preparing an element query for the query builder.

The main Query object being prepared for the query builder is available via query. The subselect’s Query object being prepared is available via subQuery. The role of the subselect query is to apply conditions to the query and narrow the result set down to just the elements that should actually be returned. The role of the main query is to join in any tables that should be included in the results, and select all of the columns that should be included in the results.

Returns

boolean – Whether the query should be prepared and returned to the query builder. If false, the query will be cancelled and no results will be returned.

`cacheTags()`

Since: 3.5.0

Returns any cache invalidation tags that caches involving this element query should use as dependencies.

Use the most specific tag(s) possible, to reduce the likelihood of pointless cache clearing.

When elements are created/updated/deleted, their craft\base\ElementInterface::getCacheTags() method will be called, and any caches that have those tags listed as dependencies will be invalidated.

View source

Returns

string[]

`customFields()`

Returns the fields that should take part in an upcoming elements query.

View source

Returns

craft\base\FieldInterface[] – The fields that should take part in the upcoming elements query

`joinElementTable()`

$table (string) – The unprefixed table name. This will also be used as the table’s alias within the query.

`normalizeOrderBy()`

Normalizes format of ORDER BY data.

View source

Arguments

$columns (array, string, yii\db\ExpressionInterface, null) – The columns value to normalize. See orderBy() and addOrderBy().

Returns

array

`statusCondition()`

Returns the condition that should be applied to the element query for a given status.

For example, if you support a status called “pending”, which maps back to a pending database column that will either be 0 or 1, this method could do this:

php

protected function statusCondition($status)
{
    switch ($status) {
        case 'pending':
            return ['mytable.pending' => true];
        default:
            return parent::statusCondition($status);
    }

View source

Arguments

$status (string) – The status

Returns

string, array, yii\db\ExpressionInterface, false, null – The status condition, or false if $status is an unsupported status

Events

EVENT_AFTER_POPULATE_ELEMENT

Type: craft\events\PopulateElementEvent

The event that is triggered after an element is populated.

If craft\events\PopulateElementEvent::$element is replaced by an event handler, the replacement will be returned by createElement() instead.

EVENT_AFTER_PREPARE

Type: craft\events\CancelableEvent

An event that is triggered at the end of preparing an element query for the query builder.

EVENT_BEFORE_PREPARE

Type: craft\events\CancelableEvent

An event that is triggered at the beginning of preparing an element query for the query builder.
