您可以尝试wp_revisions_to_keep 过滤器以覆盖WP_POST_REVISIONS 常数：

/**
 * Turn off revisions
 */
add_filter( \'wp_revisions_to_keep\', function( $num, $post )
{
    //---------------------------------
    // Adjust the $num to your needs
    //---------------------------------
    if ( post_type_supports( $post->post_type, \'revisions\' ) )
        $num = 0;

    return $num;

}, PHP_INT_MAX, 2 );

要关闭它，我们还可以尝试使用remove_post_type_support():

/**
 * Remove revisions support for posts
 */
add_action( \'init\', function()
{
    remove_post_type_support( $post_type = \'post\', $supports = \'revisions\' );
} );
