计算帖子数（自定义帖子类型）查询问题

我正在尝试计算自定义帖子类型“工作”的总帖子数。当我知道有帖子时，我的查询只会返回“ 0”。我不认为这是在检查帖子类型是否包含帖子，但是我不知道为什么...有什么想法吗？

<?php $jobs = new WP_Query(array( 'post_type' => 'jobs' ));?>
<?php if ($jobs->have_posts()) { 

    $count_posts = wp_count_posts()->publish; 
    if ( $count_posts == "1" ) { 
        echo "<h2>There is currently one vacancy...</h2>"; }
    else { echo "<h2>There are currently  $count_posts vacancies...</h2>"; }

} else { ?>
<h2>There are currently no vacancies.</h2>
<?php } ?>

该wp_count_posts函数具有$type要计算的帖子类型的参数，如果要获取作业数，则应使用此参数

像这样：

$count_posts = wp_count_posts( 'jobs' )->publish;

将它们替换为您的meta_key和meta_value：

$meta_key = 'x';
$meta_value = '2';

$sql = "SELECT count(DISTINCT pm.post_id)
FROM $wpdb->postmeta pm
JOIN $wpdb->posts p ON (p.ID = pm.post_id)
WHERE pm.meta_key = '$meta_key'
AND pm.meta_value = '$meta_value'
AND p.post_type = 'post'
AND p.post_status = 'publish'
";

$count = $wpdb->get_var($sql);
echo "<p>Count is: $count</p>";
