__construct() ​

Constructor

View source

Arguments ​

  • $elementType (class-string<\craft\elements\db\TElement>) – 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;.

View source

Arguments ​

  • $name (string) – The property name or the event name
  • $value (mixed) – The property value

Throws ​

addOrderBy() ​

Adds additional ORDER BY columns to the query.

View source

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.

Returns ​

static – The query object itself

afterPopulate() ​

Since
3.6.0

Performs any post-population processing on elements.

View source

Arguments ​

Returns ​

craft\base\ElementInterface[], array[]

all() ​

Executes the query and returns all results as an array.

View source

Arguments ​

  • $db (yii\db\Connection, null) – The database connection used to generate the SQL statement. If this parameter is not given, the db application component will be used.

Returns ​

\craft\elements\db\TElement[], array – The query results. If the query results in nothing, an empty array will be returned.

ancestorDist() ​

Narrows the query results to only {elements} that are up to a certain distance away from the {element} specified by ancestorOf().

View source

Arguments ​

Returns ​

static

Example ​

twig
{# Fetch {elements} above this one #}
{% set {elements-var} = {twig-method}
  .ancestorOf({myElement})
  .ancestorDist(3)
  .all() %}
php
// Fetch {elements} above this one
${elements-var} = {php-method}
    ->ancestorOf(${myElement})
    ->ancestorDist(3)
    ->all();

ancestorOf() ​

Narrows the query results to only {elements} that are ancestors of another {element} in its structure.

Possible values include:

ValueFetches {elements}…
1above the {element} with an ID of 1.
a [[{element-class}]] objectabove the {element} represented by the object.

TIP

This can be combined with ancestorDist() if you want to limit how far away the ancestor {elements} can be.

View source

Arguments ​

Returns ​

Returns a list of behaviors that this component should behave as.

Child classes may override this method to specify the behaviors they want to behave as.

The return value of this method should be an array of behavior objects or configurations indexed by behavior names. A behavior configuration can be either a string specifying the behavior class or an array of the following structure:

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) {

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".
joinElementTable()Joins in a table with an id column that has a foreign key pointing to elements.id.
normalizeOrderBy()Normalizes format of ORDER BY data.
normalizeSelect()Normalizes the SELECT columns passed to select() or addSelect().

resolveFields()Determines which fields can be returned by toArray().
setCommandCache()Sets $command cache, if this query has enabled caching.
statusCondition()Returns the condition that should be applied to the element query for a given status.

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.

See also:

View source

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.

See also:

View source

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.

Throws ​

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() ​

Joins in a table with an id column that has a foreign key pointing to elements.id.

The table will be joined with an alias based on the unprefixed table name. For example, if {{%entries}} is passed, the table will be aliased to entries.

View source

Arguments ​

  • $table (string) – The table name, e.g. entries or {{%entries}}

normalizeOrderBy() ​

Normalizes format of ORDER BY data.

View source

Arguments ​

Returns ​

queryScalar() ​

Queries a scalar value by setting select() first.

Restores the value of select to make this query reusable.

View source

Arguments ​

Returns ​

boolean, string, null

Throws ​

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:
