# __construct()

Constructor

View source

Arguments

  • $elementType (string) – The element type class associated with this query
  • $config (array) – Configurations to be applied to the newly created query object

# __set()

Sets the value of a component property.

This method will check in the following order and act accordingly:

  • a property defined by a setter: set the property value
  • an event in the format of "on xyz": attach the handler to the event "xyz"
  • a behavior in the format of "as xyz": attach the behavior named as "xyz"
  • a property of a behavior: set the behavior property value

Do not call this method directly as it is a PHP magic method that will be implicitly called when executing $component->property = $value;.

# 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.

Returns

string[]

# 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:

protected function statusCondition($status)
{
    switch ($status) {
        case 'pending':
            return ['mytable.pending' => 1];
        default:
            return parent::statusCondition($status);
    }

Arguments

Returns

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