Answer 1

get_next_post and get_previous_post should help you out.

Answer 2

如果它在 The Loop 内，您可以使用the_excerpt()或get_the_excerpt()根据您的要求使用。

如果它在循环之外，您可以使用这样的函数通过帖子 ID 获取帖子摘录：

function get_excerpt_by_id($post_id){
    $the_post = get_post($post_id); //Gets post ID
    $the_excerpt = $the_post->post_content; //Gets post_content to be used as a basis for the excerpt
    $excerpt_length = 35; //Sets excerpt length by word count
    $the_excerpt = strip_tags(strip_shortcodes($the_excerpt)); //Strips tags and images
    $words = explode(' ', $the_excerpt, $excerpt_length + 1);

    if(count($words) > $excerpt_length) :
        array_pop($words);
        array_push($words, '…');
        $the_excerpt = implode(' ', $words);
    endif;

    $the_excerpt = '<p>' . $the_excerpt . '</p>';

    return $the_excerpt;
}

希望这可以帮助！

Answer 3

您可以使用以下功能

对于下一篇文章链接

<?php next_post_link('format', 'link', 'in_same_cat', 'excluded_categories'); ?>

对于以前的帖子链接

<?php previous_post_link($format, $link, $in_same_cat = false, $excluded_categories = ''); ?> 

Answer 4

function content($limit) {
$excerpt = explode(' ', get_the_excerpt(), $limit);
if (count($excerpt)>=$limit) {
array_pop($excerpt);
$excerpt = implode(" ",$excerpt).'...';
} else {
$excerpt = implode(" ",$excerpt);
}   
$excerpt = preg_replace('`\[[^\]]*\]`','',$excerpt);
return $content;
}

在帖子页面中，输入这样的字数限制->回显内容（100）。希望这会帮助你。
