如果 have_posts 则帖子标题重复

Question

我正在尝试从自定义帖子类别中添加一些帖子标题。我目前让它打印正确数量的<li>，但不幸的是它是同名的。你会看到我使用 meta 缩小了范围，所以我得到了 5 个同名的结果。

我不假装是这方面的专家，所以我虚心地向社区寻求任何帮助。

提前致谢。

我试过做一个 foreach 和 if have_posts。两者都产生了相同的结果。

$page_title = get_the_title();

$args = array(
        'orderby' => 'title',
        'post_type' => 'person',
        'post_status' => 'publish',
        'meta_key' => 'division',
        'meta_value' => 'Singles'
    );

    $string = '';
    $query = new WP_Query( $args );
    if( $query->have_posts() ):
        $string .= '<ul>';
            while( $query->have_posts() ):
                $query->the_post();
                $string .= '<li>' . get_the_title() . '</li>';
            endwhile;
        $string .= '</ul>';
            echo $string;
            wp_reset_postdata();
    else :
    // No, we don't have any posts, so maybe we display a nice message
    echo "<p class='no-posts'>" . __( "Sorry, there are no posts at this time." ) . "</p>";
    endif;

所以我们要做的是查找“Singles”中存在多少帖子（在我的情况下是 5 个），并在 <li> 中打印每个帖子的标题。目前它打印 5 次中的 1 次。

get_the_title() 有以下实现

function get_the_title( $post = 0 ) {
    $post = get_post( $post );

    $title = isset( $post->post_title ) ? $post->post_title : '';
    $id    = isset( $post->ID ) ? $post->ID : 0;

    if ( ! is_admin() ) {
        if ( ! empty( $post->post_password ) ) {

            /**
             * Filters the text prepended to the post title for protected posts.
             *
             * The filter is only applied on the front end.
             *
             * @since 2.8.0
             *
             * @param string  $prepend Text displayed before the post title.
             *                         Default 'Protected: %s'.
             * @param WP_Post $post    Current post object.
             */
            $protected_title_format = apply_filters( 'protected_title_format', __( 'Protected: %s' ), $post );
            $title                  = sprintf( $protected_title_format, $title );
        } elseif ( isset( $post->post_status ) && 'private' == $post->post_status ) {

            /**
             * Filters the text prepended to the post title of private posts.
             *
             * The filter is only applied on the front end.
             *
             * @since 2.8.0
             *
             * @param string  $prepend Text displayed before the post title.
             *                         Default 'Private: %s'.
             * @param WP_Post $post    Current post object.
             */
            $private_title_format = apply_filters( 'private_title_format', __( 'Private: %s' ), $post );
            $title                = sprintf( $private_title_format, $title );
        }
    }

    /**
     * Filters the post title.
     *
     * @since 0.71
     *
     * @param string $title The post title.
     * @param int    $id    The post ID.
     */
    return apply_filters( 'the_title', $title, $id );
}

如您所见，您可以将帖子传递给它，然后它将获得其标题。由于您没有将帖子传递给它，因此它没有为您获得标题。建议：

$page_title = get_the_title();

$args = array(
        'orderby' => 'title',
        'post_type' => 'person',
        'post_status' => 'publish',
        'meta_key' => 'division',
        'meta_value' => 'Singles'
    );

    $string = '';
    $query = new WP_Query( $args );
    if( $query->have_posts() ):
        $string .= '<ul>';
            while( $query->have_posts() ):
                $string .= '<li>' . get_the_title($query->the_post()) . '</li>';
            endwhile;
        $string .= '</ul>';
            echo $string;
            wp_reset_postdata();
    else :
    // No, we don't have any posts, so maybe we display a nice message
    echo "<p class='no-posts'>" . __( "Sorry, there are no posts at this time." ) . "</p>";
    endif;
