extraFields()

Define extra fields that you _might_ want included in the `toArray()` output.

public extraFields() : array<string|int, callable>

These are virtual fields that are not included by default like the ones defined in fields(). Instead, use the second parameter of the toArray(null, ['name']) method to specify which extra fields you want in the output.

A virtual field is defined as a pair like 'name' => callback.

Return values
array<string|int, callable>

fields()

These are fields for use in `toArray()`.

public fields() : array<string|int, callable|bool>

By default this will include all public fields of the object.

Given 'name' => true a field will appear in the array output. Given false|null|0|unset|... the field will not be present.

Define a pair like 'name' => callback create a 'virtual' field. This can override existing properties or create whole new fields.

Note, if not implementing the ArrayableFields interface, this method will only define 'virtual' fields. That said, inheriting the parent fields is safe and will future-proof the code.

// Inheriting fields from the parent:
$fields = parent::fields();
$fields['hide_this_field'] = false;
unset($fields['this_also_works']);
return $fields;

// Declaring explicit fields, ignoring inherited:
return [
  'real_field' => true,
  'and_this_field' => true,
];

// Adding virtual fields:
$fields = parent::fields();
$fields['virtual_thing'] = [$this, 'getMyVirtualThing'];
$fields['inline_thing'] = function() {
   return 'hey look: ' . time();
};
return $fields;

Specify a 'filter' to restrict the fields included in the output.

Specify an 'extra' to include additional fields if implementing the ArrayableFields interface. This will add properties that were excluded from fields() and includes any virtual fields defined in extraFields(). included in fields() and any virtual fields defined in extraFields().

Performed before all save actions.

protected _beforeSave() : void

clearCache()

Trash this cache.

protected clearCache([string|null $key = null ]) : void

Maybe you've mutated something. Go on. Trash it.

Provide the key parameter to selectively delete a cached item.

Recommended placements:

  • __clone()
  • DataObject::update()
Parameters
$key : string|null = null

getCachedDate()

Get a date object version of the 'property' field.

protected getCachedDate(string $property) : DateTimeInterface

getCachedIterable()

Cache an iterable result as an array.

protected getCachedIterable(string $id, callable|iterable<string|int, mixed> $fn) : array<string|int, mixed>

More useful than you might think. This takes anything you yield and dumps it in a cached array, and also returns it.

Example:

function getItems(): array
{
    return $this->getCachedIterable('items', function() {
        yield 'key1' => 'one';
        yield 'key2' => 'two';
    });
}
Parameters
$id : string
$fn : callable|iterable<string|int, mixed>

() => iterable

Return values
array<string|int, mixed>

getCachedResult()

Cache the result of a function against a hash of the input.

protected getCachedResult(array<string|int, mixed> $inputs, mixed $fn) : mixed

This is largely identical to getCachedValue() but a bit more flexible.

Your inputs must be serializable.

Parameters
$inputs : array<string|int, mixed>
$fn : mixed

(...$inputs) => mixed

getCachedValue()

Cache the result of a function.

protected getCachedValue(string $id, callable $fn) : mixed

Use this with caution plz.

Parameters
$id : string
$fn : callable

() => mixed

Return values
mixed —

function result

getFieldList()

Get the field definitions for the table that holds this record

protected static getFieldList() : array<string, PdbColumn>
Return values
array<string, PdbColumn>

getFieldType()

Test for a field type.

protected static getFieldType(string $field_name) : string|null
Parameters
$field_name : string
Return values
string|null

getSerializedProperties()

Get an array of properties to serialize.

protected getSerializedProperties() : array<string|int, mixed>

Override this to modify the behaviour of the serializer.

By default, this returns properties that are:

  • public
  • not private or protected
  • not static
  • not implementing NotSerializable
Return values
array<string|int, mixed> —

[string => value]

typeCastValue()

Convert a property value to it's appropriate type.

protected static typeCastValue(static $instance, string $property, mixed &$value) : void

Supported types:

  • array: from JSON-encoded string
  • array: from comma-separated SET
  • bool: from '0' or '1'
  • int: from numeric string
  • float: from numeric string
  • datetime: from string
  • string: from anything else
Parameters
$instance : static
$property : string
$value : mixed
