我试图制作链接,br和斜体标签适用于手动摘录但没有运气,没有摘录中断。我已尝试了许多不同的代码,如http://bacsoftwareconsulting.com/blog/index.php/wordpress-cat/how-to-preserve-html-tags-in-wordpress-excerpt-without-a-plugin/中提出的那样,没有,现在我有了这段代码:
function wp_trim_all_excerpt($text) {
global $post;
$raw_excerpt = $text;
//Add the allowed HTML tags separated by a comma
$excerpt_length = apply_filters('excerpt_length', 150000);
$text = wp_trim_words( $text, $excerpt_length ); //since wp3.3
$allowed_tags = '<p>,<a>,<em>,<strong>,<i>,<br>';
$text = strip_tags($text, $allowed_tags);
return apply_filters('wp_trim_excerpt', $text, $raw_excerpt); //since wp3.3
}
remove_filter('get_the_excerpt', 'wp_trim_excerpt');
add_filter('get_the_excerpt', 'wp_trim_all_excerpt');
但是$ allowed_tags没有保存任何内容,我认为因为我有wp_trim,但是我已经玩了几个小时没有任何东西,我也尝试使用高级摘录插件并在页面中激活摘录,但是,不要知道为什么,有HTML工作。
有什么想法吗?
答案 0 :(得分:0)
上述解决方案仍然存在限制,因为某些HTML标记成对出现。如果摘录包含开始标记但不包含相应的结束标记,则网页的其余部分可能格式不正确。
此代码检查此类标记的摘录并根据需要添加结束标记:
