WordPress query single post by slug
PhpWordpressPhp Problem Overview
For the moment when I want to show a single post without using a loop I use this:
<?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?
Php Solutions
Solution 1 - Php
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;
?>
Solution 2 - Php
How about?
<?php
$queried_post = get_page_by_path('my_slug',OBJECT,'post');
?>
Solution 3 - Php
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 );
}
Solution 4 - Php
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 );
}
Solution 5 - Php
<?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;
}
}
