wp_nonce_tick: 这个函数用来生成一个唯一的值,可以和wp_create_nonce函数结合使用,以创建一个唯一的nonce。它通常用于确保nonce在一定时间内有效。

返回创建nonce的随时间变化的变量。

一个nonce有两个tick的寿命。处于第二个tick的nonce可以被更新,例如通过自动保存。

function wp_nonce_tick( $action = -1 ) {
		/**
		 * Filters the lifespan of nonces in seconds.
		 *
		 * @since 2.5.0
		 * @since 6.1.0 Added `$action` argument to allow for more targeted filters.
		 *
		 * @param int        $lifespan Lifespan of nonces in seconds. Default 86,400 seconds, or one day.
		 * @param string|int $action   The nonce action, or -1 if none was provided.
		 */
		$nonce_life = apply_filters( 'nonce_life', DAY_IN_SECONDS, $action );

		return ceil( time() / ( $nonce_life / 2 ) );
	}
endif;

if ( ! function_exists( 'wp_verify_nonce' ) ) :
	/**
	 * Verifies that a correct security nonce was used with time limit.
	 *
	 * A nonce is valid for 24 hours (by default).
	 *
	 * @since 2.0.3
	 *
	 * @param string     $nonce  Nonce value that was used for verification, usually via a form field.
	 * @param string|int $action Should give context to what is taking place and be the same when nonce was created.
	 * @return int|false 1 if the nonce is valid and generated between 0-12 hours ago,
	 *                   2 if the nonce is valid and generated between 12-24 hours ago.
	 *                   False if the nonce is invalid.
