Question

当我想在不使用循环的情况下显示单个帖子的时候，我使用它：

<?php
$post_id = 54;
$queried_post = get_post($post_id);
echo $queried_post->post_title; ?>

问题在于，当我移动网站时，ID通常会发生变化。有没有办法通过slug查询这篇文章？

Answer 1

来自WordPress Codex：

<?php
$the_slug = 'my_slug';
$args = array(
  'name'        => $the_slug,
  'post_type'   => 'post',
  'post_status' => 'publish',
  'numberposts' => 1
);
$my_posts = get_posts($args);
if( $my_posts ) :
  echo 'ID on the first post found ' . $my_posts[0]->ID;
endif;
?>

怎么样？

<?php
   $queried_post = get_page_by_path('my_slug',OBJECT,'post');
?>

Answer 3

一种较便宜且可重复使用的方法

function get_post_id_by_name( $post_name, $post_type = 'post' )
{
    $post_ids = get_posts(array
    (
        'post_name'   => $post_name,
        'post_type'   => $post_type,
        'numberposts' => 1,
        'fields' => 'ids'
    ));

    return array_shift( $post_ids );
}

由于wordpress api已更改，因此无法使用带有参数'post_name'的get_posts。我修改了Maartens功能：

function get_post_id_by_slug( $slug, $post_type = "post" ) {
    $query = new WP_Query(
        array(
            'name'   => $slug,
            'post_type'   => $post_type,
            'numberposts' => 1,
            'fields'      => 'ids',
        ) );
    $posts = $query->get_posts();
    return array_shift( $posts );
}
