Php 在WordPress足球池中添加分页

我正在使用wordpress插件制作一个足球池。一个非常好的插件，但是排名中没有分页。因此，当你有超过1000名参与者时，你会得到一份很长的名单

插件作者提供了一个可以用来创建分页的类。不幸的是，我的php知识在这方面非常薄弱

这是分页类：

    <?php
class Football_Pool_Pagination {
    public $show_total = true;
    public $page_param = 'paged';
    public $current_page = 1;
    public $wrap = false;

    private $total_pages = 0;
    private $total_items = 0;
    private $page_size = 20;

    public function __construct( $num_items, $wrap = false ) {
        $this->total_items = $num_items;
        $this->total_pages = $this->calc_total_pages( $num_items, $this->page_size );
        $this->current_page = $this->get_pagenum();
        $this->wrap = $wrap;
    }

    public function get_page_size() {
        return $this->page_size;
    }
    public function set_page_size( $size ) {
        $this->page_size = $size;
        $this->total_pages = $this->calc_total_pages( $this->total_items, $this->page_size );
        $this->current_page = $this->get_pagenum();
    }

    public function show( $return = 'echo' ) {
        $current_url = set_url_scheme( 'http://' . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'] );

        if ( $this->total_pages ) {
            $page_class = $this->total_pages < 2 ? ' one-page' : '';
        } else {
            $page_class = ' no-pages';
        }

        $output = '';
        if ( $this->wrap ) $output .= sprintf( '<div class="tablenav top%s">', $page_class );

        $output .= sprintf( '<div class="tablenav-pages%s">', $page_class );
        if ( $this->show_total ) {
            $output .= sprintf( '<span class="displaying-num">%s</span>'
                            , sprintf( _n( '1 item', '%s items', $this->total_items, FOOTBALLPOOL_TEXT_DOMAIN )
                                        , $this->total_items
                                )
                        );
        }

        $disable_first = $disable_last = '';
        if ( $this->current_page == 1 ) {
            $disable_first = ' disabled';
        }
        if ( $this->current_page == $this->total_pages ) {
            $disable_last = ' disabled';
        }

        $output .= '<span class="pagination-links">';
        $output .= sprintf( '<a class="first-page%s" title="%s" href="%s">&laquo;</a>'
                            , $disable_first

        $output .= sprintf( '<a class="prev-page%s" title="%s" href="%s">&lsaquo;</a>'
                            , $disable_first

                                            $current_url ) )

                                            $current_url ) )

我认为你应该使用这个插件：

它必须节省您的时间，并降低项目的复杂性


谢谢
谢谢你的回答，但这是一个为帖子和页面添加分页的插件。。。我怎样才能用它来满足我的需要。。为了让reacords获得分页？访问并找到合适的位置，然后按照此方法放置此代码
