__construct()

View source

Arguments

  • $config

createFromConfig()

Since
3.5.0

Creates a new field layout tab from the given config.

View source

Arguments

Returns

self

elementHasErrors()

Since
3.4.0

Returns whether the given element has any validation errors for the custom fields included in this tab.

View source

Arguments

Returns

boolean

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 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:

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) {
        return $model->first_name . ' ' . $model->last_name;
    },
];

In this method, you may also want to return different lists of fields based on some context information. For example, depending on scenario or the privilege of the current application user, you may return different sets of visible fields or filter out some fields.

The default implementation of this method returns attributes() indexed by the same attribute names.

Protected Methods

MethodDescription
conditional()Returns whether this element can be conditional.
defineBehaviors()Returns the behaviors to attach to this class.
defineRules()Returns the validation rules for attributes.
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.
resolveFields()Determines which fields can be returned by toArray().
settingsHtml()Returns the settings HTML for the layout element.

defineRules()

Since
3.4.0

Returns the validation rules for attributes.

See rules() for details about what should be returned.

Models should override this method instead of rules() so EVENT_DEFINE_RULES handlers can modify the class-defined rules.

View source

Returns

array

settingsHtml()

Returns the settings HTML for the layout element.

View source

Returns

string, null
