在while循环之后，限制if语句中的项目数

Question

I have a custom-made calendar lister in wordpress, which gets the custom-post type Events, which have an ACF field with the Events' date and compares it with today's date to list it. I want to limit the number of the posts to 5, but with the logic that filters out 5 events in the while loop the older events also get in the filter and count in the 5, so in the end with the comparison they are also counted in, and for eg. if I have 2 older events only 3 are show in the if statement. Here is the code:

    $args = array( 
    'post_type' => 'events', 'meta_key'=>'date', 'orderby'=>'meta_value', 'order'=>'ASC', 'posts_per_page'=>5 );

$loop = new WP_Query( $args );

while ( $loop->have_posts() ) : $loop->the_post(); 

    $title = get_the_title();

    $maindate = DateTime::createFromFormat('Ymd', get_field('date'));
    $today = DateTime::createFromFormat('Ymd', date('Ymd'));

if ( $maindate >= $today ) :

... + then the html code with the elements

Any idea how can I restructure it?

If I understand you correctly you want to list the 5 upcoming events, and leave out the old ones. You now filter them in your while loop, but you can better filter them in your query.

ACF uses Wordpress meta fields (see this link ), so you can query on those as well. This would come down to something like this:

$args = array( 
    'post_type' => 'events', 
    'meta_key'=>'date', 
    'meta_query' => [
        ['key' => 'date', 
         'value' => date('Y-m-d'), 
         'compare' => '>=']
     ],  
     'orderby'=>'meta_value', 
     'order'=>'ASC', 
     'posts_per_page'=>5 );
