我的一个页面上有以下代码。当我使用 echo get_num_queries(). 我正在尝试减少查询量，但我无法找到它们的来源。

我唯一能想到的是get_post_meta. get_post_meta 是否每次都运行查询？如果是这样，有没有更好的方法来做到这一点，所以我不会每次都运行查询？

<?php
/*  This is the second wordpress loop which will show only non paid dealers per the above wp_query in query_single.  The 0 passed is non-paid dealers*/

     query_single('dealers', 'draft', '0', $taxtype,  $value);
?>

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

<?php
$address=get_post_meta($post->ID, 'wpcf-street_address', TRUE);
$city=get_post_meta($post->ID, 'wpcf-city', TRUE);
$state=get_post_meta($post->ID, 'wpcf-state_abbreviation', TRUE);
$zip=get_post_meta($post->ID, 'wpcf-zip_code', TRUE);
$phone=get_post_meta($post->ID, 'wpcf-phone_number', TRUE);
$paid=get_post_meta($post->ID, 'wpcf-paid', TRUE);
$post_id=get_the_ID();
get_each_dealer_brand($post_id);?>

<ul class="ullisting">
<?php
if($paid==0) {

    echo "<li><p class=\"plisting\"><strong>";the_title();echo "</strong></p></li>";
    echo "<li><p class=\"plisting\">$address | $city, $state $zip</p></li>";
    echo "<li><p class=\"plisting\">P: $phone</p></li>";
    echo "<li><p class=\"listing\"><span><small>$brands_list</small></span></p></li>";
} 
?>
</ul>

您可以通过调用 get_post_meta 一次来减少查询计数 - 它会获取所有相关字段：

// will have all of your fields and more in an array, with fewer queries called
$post_meta = get_post_meta($post->ID);
var_dump($post_meta);
