请记住，我已经更改了可读性的属性，include 采用逗号分隔的类别字符串slugs （include=\'slug-1, slug-2\'）。此属性将用于包括类别。exclude 工作原理相同（exclude=\'slug-1, slug-2\'），但它采用逗号分隔的类别字符串slugs编辑
我已经测试了我的代码并修复了几个小错误。如果我只是从它创建一个普通的短代码，它就会像预期的那样工作。概念验证-短代码

我使用如下[testcode include=\'testslug-1, testslug-2\' exclude=\'testslug-3, testslug-4\']
我也测试了您的分页功能，它也按预期工作。function home_pagination( $query = null )
{
$big = 999999999; // need an unlikely integer
if ( get_query_var(\'paged\') ) {
$paged = get_query_var(\'paged\');
} elseif ( get_query_var(\'page\') ) {
$paged = get_query_var(\'page\');
} else {
$paged = 1;
}
$pagination = paginate_links(
array(
\'base\' => str_replace( $big, \'%#%\', esc_url( get_pagenum_link( $big ) ) ),
\'format\' => \'?paged=%#%\',
\'current\' => $paged,
\'total\' => $query->max_num_pages,
\'prev_text\' => \'« Previous\',
\'next_text\' => \'Next »\',
)
);
return $pagination;
}
编辑你的评论，正如我已经说过的，静态首页和单页使用get_query_var( \'page\' ) 用于分页，而所有其他用途get_query_var( \'paged\' ). 我已经用以下代码更新了上面的所有代码if ( get_query_var(\'paged\') ) {
$paged = get_query_var(\'paged\');
} elseif ( get_query_var(\'page\') ) {
$paged = get_query_var(\'page\');
} else {
$paged = 1;
}
这将对问题进行排序page 和paged 并使您的短代码和分页可以在所有页面上工作，而无需对其进行任何特定更改编辑3
Here is a sligtly modified version of the code by @ChipBennet 这将解决以下问题/page/2function home_pagination( $query = null )
{
global $wp_rewrite;
if ( get_query_var(\'paged\') ) {
$paged = get_query_var(\'paged\');
} elseif ( get_query_var(\'page\') ) {
$paged = get_query_var(\'page\');
} else {
$paged = 1;
}
$pagination = array(
\'base\' => @add_query_arg( \'paged\', \'%#%\' ),
\'format\' => \'\',
\'current\' => $paged,
\'total\' => $query->max_num_pages,
\'prev_text\' => \'« Previous\',
\'next_text\' => \'Next »\',
);
if ( $wp_rewrite->using_permalinks() )
$pagination[\'base\'] = user_trailingslashit( trailingslashit( remove_query_arg( \'s\', get_pagenum_link( 1 ) ) ).\'/%#%/\', \'\' );
if ( ! empty( $wp_query->query_vars[\'s\'] ) )
$pagination[\'add_args\'] = array( \'s\' => get_query_var( \'s\' ) );
return paginate_links( $pagination );
}
