WordPress：仅当帖子数量> 3时才显示“更多帖子”按钮

Question

UPDATE I'm actually trying to display a "More Posts" button only if there are more than 3 posts in the "News" category. The current code that I've come up with after searching Stack Overflow is as follows... but doesn't seem to be functioning properly:

<?php
$cat = get_query_var('cat');
$posts = get_posts(array('News' => $cat));
if(count($posts) > 3)
{
 echo('<div class="more-box"><a href="#">More news and events</a></div>');
}
else
{
//CODE EXECUTED IF LESS THAN THREE POSTS EXIST IN CURRENT CATEGORY
}
?>

How would display the More Button only if there are >3 posts in News?

Thank you!

Answer 1

Your code looks properly without that line:

$posts = get_posts(array('News' => $cat));

Function get_posts doesn't have parameter News. If $cat is acronym of category then you should have something like this:

$posts = get_posts(array('category' => $cat));

Then Wordpress should return list of WP_Post objects. Also to count posts you can use another internal function:

 <?php wp_count_posts( $type, $perm ); ?> 

Where:

$type (string) (optional) Post type to count

$perm (string) (optional) To include private posts readable by the current user, set to 'readable' - Default: empty string
