我试图让这个 WordPress 页面模板显示特定帖子的摘录。创建帖子后,我确定将链接插入到我想要的位置。我能够获取标题、缩略图、永久链接等......但出于某种原因我无法获取摘录。我努力了:
the_excerpt();
get_the_excerpt();
the_content('',FALSE);
get_the_content('', FALSE, '');
get_the_content('', TRUE);

除其他事项外。当我尝试时,get_the_content('', TRUE)它会为我提供链接之后所有内容的内容,但我想要链接之前的内容。
有任何想法吗?
<?php
$query = 'cat=23&posts_per_page=1';
$queryObject = new WP_Query($query);
?>
<?php if($queryObject->have_posts()) : ?>
<div>
<?php while($queryObject->have_posts()) : $queryObject->the_post() ?>
<div>
<h1><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></h1>
<br>
<?php the_post_thumbnail() ?>
<?php #the_excerpt(); ?>
<div>
<a href="<?php the_permalink(); ?>">Read More</a>
</div>
</div>
<?php endwhile ?>
</div>
<?php endif; wp_reset_query();

尝试将其添加到您的functions.php并通过帖子ID调用摘录:
\n\n//get excerpt by id\nfunction get_excerpt_by_id($post_id){\n $the_post = get_post($post_id); //Gets post ID\n $the_excerpt = ($the_post ? $the_post->post_content : null); //Gets post_content to be used as a basis for the excerpt\n $excerpt_length = 35; //Sets excerpt length by word count\n $the_excerpt = strip_tags(strip_shortcodes($the_excerpt)); //Strips tags and images\n $words = explode(' ', $the_excerpt, $excerpt_length + 1);\n\n if(count($words) > $excerpt_length) :\n array_pop($words);\n array_push($words, '\xe2\x80\xa6');\n $the_excerpt = implode(' ', $words);\n endif;\n\n return $the_excerpt;\n}\nRun Code Online (Sandbox Code Playgroud)\n\n然后在模板中这样调用它:
\n\nget_excerpt_by_id($post->ID);\nRun Code Online (Sandbox Code Playgroud)\n
这是一个非常巧妙的解决方案,可以为您解决问题!
<div class="post">
<h3 class="title"><?php echo $post->post_title ?></h3>
<?
// Making an excerpt of the blog post content
$excerpt = strip_tags($post->post_content);
if (strlen($excerpt) > 100) {
$excerpt = substr($excerpt, 0, 100);
$excerpt = substr($excerpt, 0, strrpos($excerpt, ' '));
$excerpt .= '...';
}
?>
<p class="excerpt"><?php echo $excerpt ?></p>
<a class="more-link" href="<?php echo get_post_permalink($post->ID); ?>">Read more</a>
</div>
