【问题描述】:
我想添加一个数字导航以便浏览帖子。
在我的主题主页中,我有显示帖子的代码。
<div class="container mt-80 mb-80">
<div class="card-columns">
<?php $args['tax_query'] = array(
array(
'taxonomy' => 'category',
'terms' => array('portfolio'),
'field' => 'slug',
'operator' => 'NOT IN',
),
);
query_posts($args);?>
<?php while(have_posts()) : the_post(); ?>
<div class="card">
<div class="card-body">
<a href="<?php the_permalink(); ?>" title="<?php the_title_attribute(); ?>">
<?php the_post_thumbnail('full', array('class' => 'image-post card-img-top')); ?>
</a>
<h3 class="card-title"><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></h3>
<p class="card-text"><?php echo get_the_excerpt(); ?> ...</p>
<span class="entry-date"><?php echo get_the_date(); ?></span>
</div>
</div>
<?php endwhile; wp_reset_query(); ?>
</div>
</div>
为了显示分页,我尝试在 function.php 上添加此代码
我想在帖子下方插入页码以浏览它们,但我不想安装任何插件。
function 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"; }
这个在 index.php 上
<?php numeric_posts_nav(); ?>
出现导航但无法正常工作。有谁知道为什么?
