# __call()

Calls the named method which is not a class method.

View source (opens new window)

Arguments

Returns

mixed – The method return value

Throws

# __construct()

Constructor

View source (opens new window)

Arguments

# __get()

Returns the value of a component property.

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

  • a property defined by a getter: return the getter result
  • a property of a behavior: return the behavior property value

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

View source (opens new window)

Arguments

Returns

mixed – The property value or the value of a behavior's property

Throws

# __isset()

Checks if a property is set, i.e. defined and not null.

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

  • a property defined by a setter: return whether the property is set
  • a property of a behavior: return whether the property is set

# behaviors()

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() (opens new window) when no specific fields are specified.

A field is a named element in the returned array by toArray() (opens new window). This method should return an array of field names or field definitions. If the former, the field name will be treated as an object property name whose value will be used as the field value. 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:

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.
return [
    'email',
    'firstName' => 'first_name',
    'lastName' => 'last_name',
    'fullName' => function ($model) {
        return $model->first_name . ' ' . $model->last_name;
    },
];

# 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 (opens new window)

Returns

boolean (opens new window) – 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.

# 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.

View source (opens new window)

Returns

string (opens new window)[]

# customFields()

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

View source (opens new window)

# normalizeOrderBy()

Normalizes format of ORDER BY data.

View source (opens new window)

Arguments

Returns

# 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' => true];
        default:
