修改WP_LIST_AUTHER函数以输出网格中的所有用户(和分页)

时间：2011-05-29 作者：Sam K

标题说明了一切。

我一直在使用WP\\u LIST\\u AUTHOR并对其进行修改，以创建更多的成员目录，而不仅仅是一个作者列表，同时保留许多原始选项不变（接下来我将添加更多）。我的第一个任务是在其中构建分页，我成功地做到了这一点（下面的代码）[虽然还不是很漂亮]。

我现在希望它将这些信息构建到表格中（可能每页15个结果，在3x5网格中。行-单元格-单元格-行-单元格-单元格等）。我真的不确定最好的方法是什么，或者如果可以用当前的代码构造方式来完成，那么任何建议或链接的资源都将不胜感激！我真的只是把事情拼凑在一起；）另请注意；该网站使用s2member插件，任何代码都不需要干扰该功能。

您的代码片段有点太冗长，无法理解（现在已经很晚了），因此这是一个替代方案。我认为分叉wp_list_author() 这可能太过分了。在用户搜索中挂钩，并准确地分割出您需要的作者部分，这将更加优雅。

下面是我想到的一些示例代码：

add_action(\'pre_user_query\',\'offset_authors\');

$authors_per_page = 1;
$current_page = absint(get_query_var(\'page\'));

function offset_authors( $query ) {

    global $current_page, $authors_per_page;

    $offset = empty($current_page) ? 0 : ($current_page - 1) * $authors_per_page;    
    $query->query_limit = "LIMIT {$offset},{$authors_per_page}";
}

wp_list_authors();
也请查看paginate_links() 用于生成分页的函数。

Pagination with custom loop

我的问题可能是Pagination not working with custom loop, 但有一种不同。我使用自定义循环来显示flash游戏。我想按类别在游戏页面上分页。类别php：<?php if ($cat) { $cols = 2; $rows = 4; $paged = ((\'paged\')) ? get_query_var(\'paged\') : 1; $post_per_page = $cols * $rows; // -1 s
