你要找的功能是wp_link_pages(). 默认用法如下：

wp_link_pages( 
    array(
        \'before\'           => \'<p>\' . __(\'Pages:\'),
        \'after\'            => \'</p>\',
        \'link_before\'      => \'\',
        \'link_after\'       => \'\',
        \'next_or_number\'   => \'number\',
        \'nextpagelink\'     => __(\'Next page\'),
        \'previouspagelink\' => __(\'Previous page\'),
        \'pagelink\'         => \'%\',
        \'echo\'             => 1
    )
)
