Parameters 3 required
| Name / Type | Description |
|---|---|
| $option string | Name of the option to add. Expected to not be SQL-escaped. Required |
| mixed | $value Optional. Option value. Must be serializable if non-scalar. Expected to not be SQL-escaped. Required |
| $deprecated string | Optional. Description. Not used anymore. |
| mixed | (bool | null) $autoload Optional. Whether to load the option when WordPress starts up. Accepts a boolean, or `null` to leave the decision up to default heuristics in WordPress. For backward compatibility 'yes' and 'no' are also accepted, though using these values is deprecated. Autoloading too many options can lead to performance problems, especially if the options are not frequently used. For options which are accessed across several places in the frontend, it is recommended to autoload them, by using true. For options which are accessed only on few specific URLs, it is recommended to not autoload them, by using false. Default is null, which means WordPress will determine the autoload value. Required |
