限制WordPress中的粘性帖子数量

Question

I have a website in development and the customer wanted a news and FAQ page. Not a problem! He wanted to be able to add his own posts (to both news and FAQ. Again, not a problem! The last thing he requested was that he was able to manage the amount of posts showing and what kind of posts that were shown. Now this is where i got confused. I've already build a system where the customer can select a category to show. (i'm using AwesomeBuilder for this). Now we have three different types of posts. Regular, Regular + Sticky, and Sticky. Should the client select the option to only show Regular posts i can turn the sticky posts off by using post__not_in. However if the client selects either Regular + Sticky or Sticky the amount function doesn't work anymore.

Lets say the client selects a maximum amount of 10 posts. At the regular category this gets maxed at 10 and that's it. At the sticky posts however this doesn't happen, it just shows all the sticky posts since stickies are told to always stay on top. Regular + Sticky would show all the sticky posts followed by 10 regular posts. I hope my situation and problem is clear.

Code below.

$sticky = get_option( 'sticky_posts' );
$number = $atts['number'];

if ($atts['sticky'] == 'nieuws') {
    $args = array('post__not_in'  => $sticky, 'posts_per_page' => $number );

} elseif ($atts['sticky'] == 'nieuws-sticky') {
    $sticky_count = count($sticky);
    if ($sticky_count <= $number){
        $number_sticky = $number - $sticky_count;
        $args = array('post_type' => post, 'posts_per_page' => $number_sticky);
    }
    else {
//      $sticky = array_slice($sticky,0, 1);
//      echo 'hello'. $sticky;
        $args = array('post__in'  => $sticky );
    }
} else {
//  $sticky = array_slice($sticky,1, 2);
    $args = array('post__in'  => $sticky, 'posts_per_page' => $number );
}

ps. I know THIS is the about the same question but it hasnt been answered yet.

Answer 1

确保$ number变量得到10，并确保在query_posts函数中使用$ args，例如query_posts（$ args）;。

You can refer to this "Display just the first sticky post, if none return the last post published: " from the link.
