WordPress query single post by slug
提问by George Oiko
For the moment when I want to show a single post without using a loop I use this:
目前，当我想在不使用循环的情况下显示单个帖子时，我使用以下命令：
<?php
$post_id = 54;
$queried_post = get_post($post_id);
echo $queried_post->post_title; ?>
The problem is that when I move the site, the id's usually change. Is there a way to query this post by slug?
问题是当我移动网站时，id 通常会改变。有没有办法通过 slug 查询这篇文章？

From the WordPress Codex:
来自 WordPress 法典：
<?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;
?>

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

a less expensive and reusable method
一种成本较低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 );
}

As wordpress api has changed, you can′t use get_posts with param 'post_name'. I′ve modified Maartens function a bit:
由于 wordpress api 已更改，您不能使用带有参数“post_name”的 get_posts。我稍微修改了 Maartens 函数：
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 );
}
