Question

以下是我的index.php文件

<?php get_header(); ?> 
<?php 
if(get_option('zens_home') == "blog") { ?>  
<?php include (TEMPLATEPATH . '/lib/blog-home.php'); ?> 
<?php } else { ?> 
<div id="home-content" class="clearfix"> 
<ul id="shelf"> 

<?php 
?> 

<?php while (have_posts()) : the_post(); ?>
/*Start of mark*/
<li class="box" id="post-<?php the_ID(); ?>"> 
<?php $disc = get_post_meta($post->ID, 'fabthemes_discount', true); ?> 
<?php if ( $disc ) { ?> 
<span class="salebadge"></span> 
<?php }?> 

<a href="<?php the_permalink() ?>"><img class="productshot" width="172" height="243" src="<?php get_image_url(); ?>" alt="<?php the_title(); ?>"/></a> 

<div class="pricetab clearfix"> 

<?php if ( $disc ) { ?> 
<span class="oldprice"><del> <?php echo get_post_meta($post->ID, 'fabthemes_disc-price', true) ?> </del></span> 
<?php }?> 

<span class="prodetail"><a href="<?php the_permalink() ?>"><?php $price=get_post_meta($post->ID, 'fabthemes_price', true); echo $price; ?></a></span> 
</div> 
</li> 
/*End of mark*/
<?php endwhile; ?> 
<div class="clear"></div> 
<?php getpagenavi(); ?> 

</ul> 
</div>

在它已经使用的循环之上，我还想放置以下自定义查询

$args = [
    'posts_per_page' => -1,
    'post_type'      => 'products',
    'orderby'        => 'rand', // Order these posts randomly
    'tax_query'      => [
        [
            'taxonomy' => 'product-category',
            'terms'    => 27
        ]
    ]
];
$vip_posts = new WP_Query( $args );

// Run the loop
if ( $vip_posts->have_posts() ) {
    while ( $vip_posts->have_posts() ) {
        $vip_posts->the_post();

        // Display what you want in your loop like

        echo '</br>';

    }
    wp_reset_postdata();
}

但是，如果没有将其作为我主页上的明文或者发现自己出现某种语法错误，我就无法正常使用。

问题是我无法获取我在index.php的代码中标记的元素，并在使用自定义查询的循环之后启动

此处更简洁的方法是通过loop_start操作添加自定义查询。这样做的好处是您根本不需要更改模板文件。如果你愿意，你可以简单地将你的代码放在functions.php或插件中（我总是喜欢）

另一个优点是循环彼此分开，根据另一个问题你需要的东西，所以这种方法非常适合

以下代码未经测试，但应该让您了解如何使用操作

add_action( 'loop_start', function ( \WP_Query $q )
{
    // Make sure we only target the main query, if not, bail
    if ( !$q->is_main_query() ) 
        return;

    // Set a static counter to make sure this runs only once to avoid infinitive loops
    static $count = 0;

    // Make sure our counter is 0, if not, bail
    if ( 0 != $count )
        return;

    // Update our counter
    $count++;

    // This is the main query, lets target specific pages only
    if (    $q->is_home()
         || $q->is_post_type_archive( 'products' )
         || $q->is_tax( 'product-category' )
    ) {
        // Bail on vip pages
        if ( $q->is_tax( 'product-category', 'vip' ) ) // Make sure about vip slug
            return;

        // Bail if this is not the first page
        if ( $q->is_paged() )
            return;

        // Lets add our custom loop
        global $wp_query;

        $args = [
            'posts_per_page' => -1,
            'post_type'      => 'products',
            'orderby'        => 'rand', // Order these posts randomly
            'tax_query'      => [
                [
                    'taxonomy' => 'product-category',
                    'terms'    => 27
                ]
            ]
        ];
        $vip_posts = new WP_Query( $args );

        // Run the loop
        if ( $vip_posts->have_posts() ) {
            while ( $vip_posts->have_posts() ) {
                $vip_posts->the_post();

                // Display what you want in your loop like
                the_title();
                echo '</br>';

            }
            wp_reset_postdata();
        }

        // Lets make sure our main loop counter starts at -1
        $wp_query->rewind_posts();
    }
});

我该如何在index.php中实现这个自定义查询？
