Extending WordPress Options API, read options from places other than database, the OOP way.

The Goals, or What This Package Does?

WordPress Option API only allows you get_option from database. This package is for those who not accepting the status quo.


Installation should be done via composer, details of how to install composer can be found at

$ composer require typisttech/wp-option-store

You should put all WP Option Store classes under your own namespace to avoid class name conflicts.



use TypistTech\WPOptionStore\Factory;

// By default, the `Factory` adds 2 strategies (order matters):
//  1. ConstantStrategy
//  2. DatabaseStrategy
$filteredOptionStore = Factory::build();

// To get an option from strategies:
//  1. Read `MY_OPTION` constant
//  2. If (1) is not `null`, jump to (6)
//  3. Read from `get_option('my_option')`, the normal WordPress Options API
//  4. If (3) is not `null`, jump to (6)
//  5. We have tried all strategies, pass `null` to (6)
//  6. Pass whatever we have read (could be null) through `apply_filters('my_option', $whateverWeHaveRead);`

// To get an option and perform type cast.


This strategy gets options from PHP constants.

define('MY_OPTION', 'abc123');

$strategy = new ConstantStrategy();

$value1 = $strategy->get('my_option');
// $value1 === 'abc123';

$value2 = $strategy->get('my_non_exist_option');
// $value2 === null;


This strategy gets options from WordPress Options API.

update_option('my_option', 'abc123');

$strategy = new DatabaseStrategy();

$value1 = $strategy->get('my_option');
// $value1 === 'abc123';

$value2 = $strategy->get('my_non_exist_option');
// $value2 === null;

Important: An unset value should be null instead of WordPress' default false.


This class gets option values from strategies.

__construct(StrategyInterface ...$strategies)

OptionStore constructor.

  • @param StrategyInterface[] ...$strategies Strategies that get option values.
$databaseStrategy = new DatabaseStrategy();
$constantStrategy = new ConstantStrategy();
$optionStore = new OptionStore($constantStrategy, $databaseStrategy);

Note: Strategies order matters!

get(string $optionName)

Get an option value.

  • @param string $optionName Name of option to retrieve.
// It returns the first non-null value from strategies.
define('MY_OPTION', 'abc');
update_option('my_option', 'xyz');

$value1 = $optionStore->get('my_option');
// $value1 === 'abc';

// It returns `null` when option not found.
$value2 = $optionStore->get('my_non_exist_option');
// $value2 === null;

Type casting

OptionStore provides several helper methods for type casting.



This is a subclass of OptionStore.

get(string $optionName)

Get an option value.

  • @param string $optionName Name of option to retrieve.
// It returns the first non-null value from strategies,
// and applies filters.
define('MY_OPTION', 'abc');
update_option('my_option', 'xyz');

add_filter('my_option', function($value) {
    return 'filtered ' . $value;

$value = $filteredOptionStore->get('my_option');
// $value === 'filtered abc';

Note: Filters are applied before type casting.


Factory is a helper class to reduce boilerplate code for those who use default strategies. If you use a custom strategy or reorder the strategies, don't use this class.

build(): FilteredOptionStore

$filteredOptionStore = Factory::build();

Frequently Asked Questions

Can I implement my own strategy classes?

Of course! Just implements the StrategyInterface.

Take a look at classes ConstantStrategy and DatabaseStrategy as well as their tests for example implementations of StrategyInterface.

If you'd like to create a open-source package to do this to help others, open a new issue to let us know, we'd love to help you with it.

Can I change the order of the strategies?

Why not? Don't use Factory.

// Order matters!
$optionStore = new FilteredOptionStore(
    new MyStrategy1(),
    new MyStrategy2(),
    new MyStrategy3(),

Is this a plugin?

No, this is a package that should be part of your plugin.

What to do when plugin team tell me to clean up the vendor folder?

Re-install packages via the following command. This package exports only necessary files to dist.

$ composer install --no-dev --prefer-dist --optimize-autoloader

Can two different plugins use this package at the same time?

Yes, if put all WP Option Store classes under your own namespace to avoid class name conflicts.

Do you have real life examples that use this package?

Here you go:

Add your own plugin here

Will you add support for older PHP versions?

Never! This plugin will only work on actively supported PHP versions.
