WordPress最近的新闻/帖子，带或不带特色图片

Posted 2021-02-24

This will show a number of recent posts along with their associated featured image (thumbnail) if they have one. The template code asks for the 2 most recent posts with the custom post type of "news." Change the quantity and post type as needed. This also uses a custom excerpt generator, which isn't necessary except that this particular code references it.

<?php
 
// custom excerpt generator. put into functions.php.
function flexcerpt($excerpt = '', $excerpt_length = 50, $readmore = "Read more&raquo;", $tags = '<a>', $permalink = null) {
	global $post;
	$excerpt = strip_tags($excerpt, $tags);
	$excerpt = strip_shortcodes($excerpt);
	$string_check = explode(' ', $excerpt);
	if ($permalink === null) {
		$permalink = get_permalink();
	}
 
	if (count($string_check, COUNT_RECURSIVE) > $excerpt_length) {
		$new_excerpt_words = explode(' ', $excerpt, $excerpt_length+1);
		array_pop($new_excerpt_words);
		$excerpt_text = implode(' ', $new_excerpt_words);
		$temp_content = strip_tags($excerpt_text, $tags);
		$excerpt = preg_replace('|[(.+?)](.+?[/\1])?|s','',$temp_content);
		// $excerpt .= ' ... <a href="' . $permalink . '">' . $readmore . '</a>';
		// return $excerpt;
	} else {
		//return $excerpt;
	}
 
	$excerpt .= '... <a href="' . $permalink . '">' . $readmore . '</a>';
	return $excerpt;
}
 
?>
