如果页面模板位于子文件夹中，请选择主题文件夹/页面模板/页面模板。php然后您可以使用下面的查询：

$page_details = get_pages( array(
 \'post_type\' => \'page\',
 \'meta_key\' => \'_wp_page_template\',
 \'hierarchical\' => 0,
 \'meta_value\' => \'page-templates/page-template.php\'
));

谢谢

如果需要的话，下面是一个更加清晰的脚本，它考虑了一种语言。注意，它假定使用的是Polylang，而不是WPML。

function get_post_id_by_template($template,$lang_slug = null){
  global $wpdb;
  $wh = ($lang_slug) ? " AND t.slug = %s" : "";

  $query = $wpdb->prepare(
    "SELECT DISTINCT p.ID
    FROM $wpdb->posts p
    INNER JOIN $wpdb->postmeta meta ON meta.post_id = p.ID
    INNER JOIN $wpdb->term_relationships tr ON meta.post_id = tr.object_id
    INNER JOIN $wpdb->term_taxonomy tt ON tr.term_taxonomy_id = tt.term_taxonomy_id
    INNER JOIN $wpdb->terms t ON tt.term_id = t.term_id
    WHERE p.post_status = \'publish\' AND meta.meta_key = %s AND meta.meta_value = %s" . $wh,
    \'_wp_page_template\',
    $template,
    $lang_slug
  );

  $ids = $wpdb->get_results($query);

  if($ids && isset($ids[0])){
    $p = $ids[0];
    return $p->ID;
  } else {
    return false;
  }
}// get_post_id_by_template

下面是一个可用于WPML和Polylang的完整函数。贷记至https://github.com/cyrale/

/**
* Search for a page with a particular template.
*
* @param string $template Template filename.
* @param array  $args     (Optional) See also get_posts() for example parameter usage.
* @param bool   $single   (Optional) Whether to return a single value.
*
* @return Will be an array of WP_Post if $single is false. Will be a WP_Post object if the page is find, FALSE otherwise
