使用query_posts，wp_query或get_posts在页面中创建各种自定义循环是更好的练习吗？

Question

现在，我正在使用 get_posts 要检索Cusstom的帖子类型，其中分配了自定义分类法以生成这样的静态内容：

<?php
/**
 * Template Name: Front Page
 * @package WordPress
 * @subpackage Prominent
 * @since Prominent 1.0
 */
get_header(); ?>
<div class="shadow-top">
    <!-- Shadow at the top of the slider -->
</div>
<div id="intro">
    <div class="container">
        <div id="slider-wrapper">
            <div id="slider">
            <?php // Create custom loop ?>
            <?php $custom_posts = get_posts('post_type=page_content&page_sections=Slider (Front Page)'); ?>
            <?php foreach( $custom_posts as $post ) : setup_postdata( $post ); ?>
                <p><?php the_content(); ?></p>
            <?php endforeach; ?>
            <?php wp_reset_query(); ?>
            </div>
            <div class="shadow-slider">
                <!-- Shadow at the bottom of the slider -->
            </div>
        </div><!-- #slider-wrapper -->
    </div><!-- .container -->
</div><!-- #featured -->
<div class="shadow-bottom">
    <!-- Shadow at the bottom of the slider -->
</div>
<div id="tagline">
    <div class="container">
        <?php
        $page_id = $post->ID; // 123 should be replaced with a specific Page's id from your site, which you can find by mousing over the link to edit that Page on the Manage Pages admin page. The id will be embedded in the query string of the URL, e.g. page.php?action=edit&post=123.
        $page_data = get_page( $page_id ); // You must pass in a variable to the get_page function. If you pass in a value (e.g. get_page ( 123 ); ), Wordpress will generate an error.

        $content = apply_filters('the_content', $page_data->post_content); // Get Content and retain Wordpress filters such as paragraph tags. Origin from: http://wordpress.org/support/topic/get_pagepost-and-no-paragraphs-problem
        $title = $page_data->post_title; // Get title
        ?>
        <div class="content0">
            <h2><?php echo $content; // Output Content ?></h2>
        </div>
    </div><!-- .container -->
</div><!-- #content-bottom -->
<div id="content">
    <div class="container">
        <div class="mainbar">
            <?php // Create custom loop
            $custom_posts = get_posts('post_type=page_content&page_sections=Content (Front Page)'); ?>
            <?php foreach( $custom_posts as $post ) : setup_postdata( $post ); ?>
                <div class="content-block">
                    <h2><?php the_title(); ?></h2>
                    <p><?php the_content(); ?></p>
                </div><!-- .content-block -->
            <?php endforeach; ?>
            <?php wp_reset_query(); ?>
        </div><!-- #mainbar -->
    </div><!-- .container -->
</div><!-- #content-bottom -->
<?php get_footer(); ?>

在这种情况下，什么是更好的练习？

使用query_posts，wp_query或get_posts？

Answer 1

你好 @Janochen：

如果您有选择， 去 WP_Query. 其他两个功能（query_posts() 和 get_posts()） 称呼 WP_Query 间接。

前者旨在允许您在运行标准查询后修改主查询，例如，当您想要第二个循环时。但 query_posts() 影响全局变量，并具有副作用。如果可能的话，请改用WP_QUERY，您的代码将更加强大。

至于 get_posts(), ，只是周围的包装纸 WP_Query 有一些潜在的意外默认值，所以您不妨致电 WP_Query 直接避免这些问题。
