WP_Site_Health_Auto_Updates::test_constants() WordPress Method

The WP_Site_Health_Auto_Updates::test_constants() method is used to check for the existence of the constants necessary for the auto-updates feature to work. This includes the WP_AUTO_UPDATE_CORE constant, as well as the AUTOMATIC_UPDATER_DISABLED and WP_AUTO_UPDATE_CORE constants. If any of these constants are not defined, the auto-updates feature will not be enabled.

WP_Site_Health_Auto_Updates::test_constants( string $constant, bool|string|array $value ) #

	public function test_constants( $constant, $value ) {
		$acceptable_values = (array) $value;

		if ( defined( $constant ) && ! in_array( constant( $constant ), $acceptable_values, true ) ) {
			return array(
				'description' => sprintf(
					/* translators: %s: Name of the constant used. */
					__( 'The %s constant is defined and enabled.' ),
					"<code>$constant</code>"
				),
				'severity'    => 'fail',
			);
		}
