也许像这样的方法行得通？

// Assuming $posts = new WP_Query( $args );
$post_to_remove = 123;
// If using post objects
foreach ( $posts->posts as $i => $post ) {
  if ( $post_to_remove == $post->ID ) {
    unset( $posts->posts[$i] );
    break; // no need to continue the loop as the post has been found
  }
}
// If only IDs were queried
foreach ( $posts->posts as $i => $post_id ) {
  if ( $post_to_remove == $post_id ) {
    unset( $posts->posts[$i] );
    break; // no need to continue the loop as the post has been found
  }
}
// do your rendering while/for/foreach loop after sorting

<?php if (have_posts()) : ?>

    <?php while (have_posts()) : the_post(); ?>

        <?php if ( $post_to_remove == get_the_id() ) { continue; } ?>

    <?php endwhile; ?>

        <?php // Navigation ?>

    <?php else : ?>

        <?php // No Posts Found ?>

<?php endif; ?>
