簡單的數字下載和分頁

Question

我試圖讓我的分頁與我的網站上的自定義下載頁面一起工作。我使用簡易數字下載作爲我的商店後端，並在自定義wp_query中調用商店商品。我有相同的代碼來分頁我的檔案，但由於某種原因，它不在這裏工作。我將不勝感激任何可以提供的幫助。這裏是我的代碼：

從我functions.php文件

/* Pagination numbers function 
------------------------------------ 
Allows Google-like page numbers to post pages by calling function */ 

function custom_numeric_posts_nav() { 

    if(is_singular()) 
     return; 

    global $wp_query; 

    /** Stop execution if there's only 1 page */ 
    if($wp_query->max_num_pages <= 1) 
     return; 

    $paged = get_query_var('paged') ? absint(get_query_var('paged')) : 1; 
    $max = intval($wp_query->max_num_pages); 

    /** Add current page to the array */ 
    if ($paged >= 1) 
     $links[] = $paged; 

    /** Add the pages around the current page to the array */ 
    if ($paged >= 3) { 
     $links[] = $paged - 1; 
     $links[] = $paged - 2; 
    } 

    if (($paged + 2) <= $max) { 
     $links[] = $paged + 2; 
     $links[] = $paged + 1; 
    } 

    echo '<div class="navigation"><ul>' . "\n"; 

    /** Previous Post Link */ 
    if (get_previous_posts_link()) 
     printf('<li>%s</li>' . "\n", get_previous_posts_link()); 

    /** Link to first page, plus ellipses if necessary */ 
    if (! in_array(1, $links)) { 
     $class = 1 == $paged ? ' class="active"' : ''; 

     printf('<li%s><a href="%s">%s</a></li>' . "\n", $class, esc_url(get_pagenum_link(1)), '1'); 

     if (! in_array(2, $links)) 
      echo '<li>…</li>'; 
    } 

    /** Link to current page, plus 2 pages in either direction if necessary */ 
    sort($links); 
    foreach ((array) $links as $link) { 
     $class = $paged == $link ? ' class="active"' : ''; 
     printf('<li%s><a href="%s">%s</a></li>' . "\n", $class, esc_url(get_pagenum_link($link)), $link); 
    } 

    /** Link to last page, plus ellipses if necessary */ 
    if (! in_array($max, $links)) { 
     if (! in_array($max - 1, $links)) 
      echo '<li>…</li>' . "\n"; 

     $class = $paged == $max ? ' class="active"' : ''; 
     printf('<li%s><a href="%s">%s</a></li>' . "\n", $class, esc_url(get_pagenum_link($max)), $max); 
    } 

    /** Next Post Link */ 
    if (get_next_posts_link()) 
     printf('<li>%s</li>' . "\n", get_next_posts_link()); 

    echo '</ul></div>' . "\n"; 

}

     </div> <!-- END #store-item --> 

    <?php endwhile; ?> 

    <!-- Call custom numbered pages --> 
    <?php custom_numeric_posts_nav(); ?>

    <?php } ?> <!-- endif --> 

?> 

Answer 1

那是因爲裏面custom_numeric_posts_nav()你使用全局變量$wp_query，而在你的自定義查詢$my_download_query 。

你可以改變custom_numeric_posts_nav()接受可變$my_download_query作爲可選的參數，如果順利通過，使用：

function custom_numeric_posts_nav($query = '') { 

    if(!$query) 
     $query = $GLOBALS['wp_query']; 

    /** Stop execution if there's only 1 page */ 
    if($query->max_num_pages <= 1) 
     return; 

    // ... and change the rest of the function accordingly ... 

} 

這時候你怎麼稱呼它：

<!-- Call custom numbered pages --> 
<?php custom_numeric_posts_nav($my_download_query); ?>
