WordPress option with some safeguards

---

A simple wrapper that adds validation and enforcing consistencies when dealing with WordPress options, such as when adding, updating, and retrieving an option. It supports both *_option as well as the corresponding function for network-enable installatiopn, *_site_option functions.

Why?

WordPress option can handle various type of values including strings, booleans, arrays, and integers. However, it lacks the capability to check the type of value being stored or retrieved. The retrieved value can vary depending on the type value stored in the option, for example:

• false returns string(0) ""
• true returns string(1) "1"
• 0 returns string(1) "0"
• 1 returns string(1) "1"
• '0' returns string(1) "0"
• '1' returns string(1) "1"
• null returns string(0) ""

It is the responsibility of developers to ensure that the value of the option aligns with the expected type. This library aims to help handling this situation better by enabling developers to implement validations, ensuring the correct type of values when adding, updating, and retrieving an option value.

Installation

composer require syntatis/wp-option

Usage

First, create an instance of the Option class from the library and define the schema of the options. The schema is an array of options where the key is the name of the option and the value is an array of the option's schema defining:

Schema	Description	Values
type	The type of the option value	The value can be one of the following: string, boolean, integer, float, and array.
default	The default value of the option	Ideally, the value should be of the same type as the type value.

use Syntatis\WP\Hook\Hook;
use Syntatis\WP\Option\Option;

$option = new Option(new Hook());
$option->setSchema([
  'wporg_custom_option' => [
    'type' => 'integer',
  ],
]);
$option->register();

After the schema defined and registered, it will ensure that the returned value of the option is of the correct type. For example, if the option value is "1" (numeric string) and the type defined in the schema for the option is integer, the value will be converted to 1 when retrieved.

add_option('wporg_custom_option', '1');
get_option('wporg_custom_option'); // int(1)

By default, when a default is not set for the option registered, the value returned will be a null, instead of a false as how WordPress handles it.

get_option('wporg_custom_option'); // null

If the option is defined in the schema, the default value will be returned instead.

use Syntatis\WP\Hook\Hook;
use Syntatis\WP\Option\Option;

$option = new Option(new Hook());
$option->setSchema([
  'wporg_custom_option' => [
    'type' => 'integer',
    'default' => 0,
  ],
]);
$option->register();

get_option('wporg_custom_option'); // int(0)
