Parameters 3 required
| Name / Type | Description |
|---|---|
| $option string | Name of the option to update. Expected to not be SQL-escaped. Required |
| $value mixed | Option value. Must be serializable if non-scalar. Expected to not be SQL-escaped. Required |
| mixed | (bool | null) $autoload Optional. Whether to load the option when WordPress starts up. Accepts a boolean, or `null` to stick with the initial value or, if no initial value is set, to leave the decision up to default heuristics in WordPress. For existing options, `$autoload` can only be updated using `update_option()` if `$value` is also changed. 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. For non-existent options, the default is null, which means WordPress will determine the autoload value. Required |
