The best of the above solution is that if i have the same name field in other post types i can check them as featured and there can only be one – allways.
And the query to put the featured post in the top off all posts:
<?php
$args = [
'post_type' => ['post', 'evento'],
'meta_key' => 'post_em_destaque',
'orderby' => 'meta_value post_date',
'post_status' => 'publish',
'posts_per_page' => 6,
'paged' => $paged
];
$the_query = new WP_Query( $args );
?>
And tho show and style the post as you wish inside the loop:
<?php if ( $the_query->have_posts() ) : ?>
<?php while ( $the_query->have_posts() ) : $the_query->the_post(); ?>
<?php if ( get_field( 'post_em_destaque' ) ): ?>
// The contetn of the featured post here
<?php else: ?>
// The rest of the posts
<?php endif; ?>
<?php endwhile; ?>
<?php wp_reset_postdata(); ?>
<?php endif; ?>
Hope this can be useful for someone in time.
