Query or show a specific post in wordpress


If you are looking for php code or a plugin for your WordPress that takes a post ID and returns the database record for that post then read on. This is very helpful when you want to show a specific post on your homepage or other pages to get more attention. It allows you to design your homepage or a page with the post(s) that you want to be shown on the page rather than the 10 recent posts that the WordPress automatically chooses for you.

PHP CODE EXAMPLE

Example 1

The following code will Query the post with post id 26 and Show the title and the content.

<?php
$post_id = 26;
$queried_post = get_post($post_id);
$title = $queried_post->post_title;
echo $title;
echo $queried_post->post_content;
?>

Example 2

The following style could be more useful as it lets the user customise the font easily.

<?php
$post_id = 26;
$queried_post = get_post($post_id);
?>
<h2><?php echo $queried_post->post_title; ?></h2>
<?php echo $queried_post->post_content; ?>

Example 3

Using an Array… The following code will query every post number in ‘thePostIdArray’ and show the title of those posts.

<?php $thePostIdArray = array("28","74", "82", "92"); ?>
<?php $limit = 4 ?>
<?php if (have_posts()) : ?>
<?php while (have_posts()) : the_post(); $counter++; ?>
<?php if ( $counter < $limit + 1 ): ?>
<div id="post-<?php the_ID(); ?>">
<?php $post_id = $thePostIdArray[$counter-1]; ?>
<?php $queried_post = get_post($post_id); ?>
<h2><?php echo $queried_post->post_title; ?></h2>
</div>
<?php endif; ?>
<?php endwhile; ?>
<?php endif; ?>

How to Display the Post Content Like WordPress

When you retrieve the post content from the database you get the unfiltered content. If you want to achieve the same output like WordPress does in its’ posts or pages then you need to apply filter to the content. You can use the following code:

<?php
$post_id = 26;
$queried_post = get_post($post_id);
$content = $queried_post->post_content;
$content = apply_filters('the_content', $content);
$content = str_replace(']]>', ']]&gt;', $content);
echo $content;
?>

Using a Plugin

You can also use the Get-a-Post WordPress plugin to query a specific post.
