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

Signature

public void __construct ( $elementType, array $config = [] )

__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

MethodDescription
afterPrepare()This method is called at the end of preparing an element query for the query builder.
beforePrepare()This method is called at the beginning of preparing an element query for the query builder.
cleanUpTableNames()Clean up table names and aliases Both aliases and names are enclosed into {{ and }}.
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".
extractRootFields()Extracts the root field names from nested fields.
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 craft_elements.id.
normalizeOrderBy()Normalizes format of ORDER BY data.
queryScalar()Queries a scalar value by setting select() first.
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.

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.

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.

Signature

protected boolean beforePrepare ( )

customFields()

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

These fields will get their own criteria parameters in the craft\elements\db\ElementQueryInterface that gets passed in, their field types will each have an opportunity to help build the element query, and their columns in the content table will be selected by the query (for those that have one). If a field has its own column in the content table, but the column name is prefixed with something besides “field_”, make sure you set the columnPrefix attribute on the craft\base\Field, so craft\services\Elements::buildElementsQuery() knows which column to select.

View source

Returns

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

Signature

protected craft\base\FieldInterface[] customFields ( )
