WordPress 查询单篇文章

当我想显示一篇文章而不用循环时，我使用以下方法:

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

问题是当我移动站点时，id 通常会改变。有没有办法通过蛞蝓来查询这篇文章？

From the 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;
?>

How about?

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

a less expensive and reusable method

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:

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 );
}

<?php
$page = get_page_by_path('slug', ARRAY_N);
echo $page->post_content


function get_id_by_slug($page_slug) {
$page = get_page_by_path($page_slug, ARRAY_N);
if ($page[0] > 0) {
return $page[0];
}else{
return null;
}
}
