控制Wordpress中显示的链接数

Question

我使用下面的代码来显示边栏中最喜欢的帖子的链接，但我想控制链接的数量，只显示3个链接，如果超出了这一点，我希望链接查看所有的最爱显示。

PHP：

<?php
$favorites = va_get_dashboard_favorites($dashboard_user->ID, (bool) $is_own_dashboard );

if ( $favorites->post_count > 0 ) {
while ( $favorites->have_posts() ) : $favorites->the_post();

$post_status = $is_own_dashboard ? 'post-status' : '';
?>
<article id="post-<?php the_ID(); ?>" <?php post_class( $post_status ); ?>>
    <a href="<?php echo get_permalink($ID); ?>">My link to a post or page</a><?php echo    get_the_title($ID); ?>
</article>
<?php
endwhile;
} else {
?>

<?php
}
 }          

我怎样才能做到这一点？

请帮帮忙

Answer 1

我在其他地方找到了va_get_dashboard_favorites函数，它看起来是相同的。最简单的方法是限制va_get_dashboard_favorites() WP_Query。例如：

方法1

这段代码是在wp-content/themes/vantage-new/includes/dashboard.php中找到的，顺便说一句

function va_get_dashboard_favorites( $user_id, $self = false ) {

    $favorites = new WP_Query( array(
      'connected_type'  => 'va_favorites',
      'connected_items' => $user_id,
      'nopaging'        => true,
      'posts_per_page' => 3, // limiting posts to 3
    ) );

    return $favorites;

}

然后，要添加一个视图-所有的链接，只需将其添加到iunder循环中即可。例如：

<?php
    $favorites = va_get_dashboard_favorites($dashboard_user->ID, (bool) $is_own_dashboard );

    if ( $favorites->post_count > 0 ) {
        while ( $favorites->have_posts() ) : $favorites->the_post();

        $post_status = $is_own_dashboard ? 'post-status' : '';
?>
    <article id="post-<?php the_ID(); ?>" <?php post_class( $post_status ); ?>>
    <?php get_template_part( 'content-listing', get_post_status() ); ?>
    </article>
<?php
        endwhile;
?>
    <br /><a href="#yourview-all-link-here">View all</a>
<?php
    } else {
?>

方法2(根据OP的更新更新)

根据OP的注释，更新后的代码仅显示3个链接

<?php
    $favorites = va_get_dashboard_favorites($dashboard_user->ID, (bool) $is_own_dashboard );

    $counter = 0;
    $max = 3;
    if ( $favorites->post_count > 0 ) {
        while ( $favorites->have_posts() and ($counter < $max)) : $favorites->the_post();

            $post_status = $is_own_dashboard ? 'post-status' : '';
?>
    <article id="post-<?php the_ID(); ?>" <?php post_class( $post_status ); ?>>
    <?php get_template_part( 'content-listing', get_post_status() ); ?>
    </article>
<?php
            $counter++;
        endwhile;
?>
    <br /><a href="#yourview-all-link-here">View all</a>
<?php
    } else {
?>

Answer 2

我相当肯定WP_Query会在这种情况下工作。

<?php $posts = WP_Query(array(
   'posts_per_page' => 3
    //any other options can go in this array
)); ?>
// Your code goes here
<?php wp_reset_query(); ?> //This makes sure your query doesn't affect other areas of the page
