I want to list ‘n’ number of posts (ordered by latest first) — post’s title linked to the post’s permalink — from a tag on my WordPress blog. I also want to assign each link its own class or ID.
I checked this doc on WordPress Codex, which is very relevant to what I need, but makes little sense to me (and I’m therefore unable to modify it to my needs).
Hope I am clear enough, if not, I can try to clarify.
EDIT: Just so it’s clear, I want to be able to list the posts wherever I want. Any template.

Method 1
get_posts() is for ‘secondary’ loops – ones that exist along-side the main Loop, usually in a side-bar or at the bottom listing ‘related’ posts etc. get_posts() is called from within a template page. So it is the wrong thing to use here.
You’ll want to alter the main query as outlined in: When to use WP_query(), query_posts() and pre_get_posts
add_action('pre_get_posts','wpse50857_alter_query');
function wpse50857_alter_query($query){
//Check other conditionals depending on when you want to alter the loop
if( $query->is_main_query() && is_home() ){
$tax_query = array(array(
'taxonomy' => 'post_tag',
'field' => 'slug',
'terms' => 'my-tag'
));
$query->set('tax_query',$tax_query);
$query->set('posts_per_page',5);
}
}
Note this over-rides any previous tax_query (this doesn’t matter in this context – but if it should you can get the previous tax_query and merge it with the new one…)
Other conditionals available here.
To edit how the posts are display, you’ll need to edit the appropriate template page (home.php?, front-page.php?).
The loop will be something like:
if( have_posts() ):
while( have_posts() ): the_post();
//The loop
?>
<h1 class="entry-title"><a href="<?php the_permalink(); ?>" rel="nofollow noreferrer noopener" rel="nofollow noreferrer noopener" rel="nofollow noreferrer noopener" rel="nofollow noreferrer noopener"><?php the_title(); ?></a></h1>
<?php
endwhile;
endif;
and you can edit that the display whatever you like.
Method 2
I don’t know PHP, so’ll try to explain after showing you the example PHP code that’s needed to do what’s asked in the question.
CODE:
<!-- Featured Posts -->
<div id="featured-posts">
<?php
$count = 0;
$some_featured_posts = new WP_Query(array('tag' => 'example2', 'posts_per_page' => 7));
while ($some_featured_posts->have_posts()):
$some_featured_posts->the_post();
$count++;
?>
<div class="featured-posts-wrapper<?php echo $count; ?> featured-posts-wrapper<?php echo ($count == 7) ? ' no-margin-right' : ''; ?>">
<a href="<?php the_permalink(); ?>" rel="nofollow noreferrer noopener" rel="nofollow noreferrer noopener" rel="nofollow noreferrer noopener" rel="nofollow noreferrer noopener" title="<?php the_title_attribute(); ?>"><img id="featured<?php echo $count; ?>" class="featured" alt="<?php the_title_attribute(); ?>" src="<?php echo get_post_meta($post->ID, 'image', true); ?>" /></a>
<a id="featured-text<?php echo $count; ?>" href="<?php the_permalink(); ?>" rel="nofollow noreferrer noopener" rel="nofollow noreferrer noopener" rel="nofollow noreferrer noopener" rel="nofollow noreferrer noopener" title="<?php the_title_attribute(); ?>"><?php the_title(); ?></a>
</div>
<?php
endwhile;
wp_reset_postdata();
?>
</div>
<!-- Featured Posts -->
PS: I’ve included the div tags and classes hoping that they’ll help the clueless. So, first put the code in a template, and check how and what it outputs, to get a better idea.
EXPLANATION:
- Add the code in any template of your choice (header.php, index.php, home.php, archive.php, search.php, content.php, or any other). That’s where you’ll see the output.
-
Change the number (
7) in this line to a number that’s equal to the number of posts you want it to show:$some_featured_posts = new WP_Query(array('tag' => 'example2', 'posts_per_page' => 7));In the above code, the
'tag' => 'example2'says that the latest posts tagged “example2” are to be shown. If you want to have a category instead, use'category_name' => 'example2' -
In this line:
<div class="featured-posts-wrapper<?php echo $count; ?> featured-posts-wrapper<?php echo ($count == 7) ? ' no-margin-right' : ''; ?>">
I use
class="featured-posts-wrapper<?php echo $count; ?>so that I can have a different class for each post that’s output. To be specific, the code above outputs asclass="featured-posts-wrapper1"for the first post,class="featured-posts-wrapper2"for the second post, and so on.On the other hand,
<?php echo ($count == 7) ? ' no-margin-right' : ''; ?>allows you to set a specific class for the last entry (as per the example, the 7th post). The code above, addsno-margin-rightclass to the last post in the output. -
In this line:
<a href="<?php the_permalink(); ?>" rel="nofollow noreferrer noopener" rel="nofollow noreferrer noopener" rel="nofollow noreferrer noopener" rel="nofollow noreferrer noopener" title="<?php the_title_attribute(); ?>"><img id="featured<?php echo $count; ?>" class="featured" alt="<?php the_title_attribute(); ?>" src="<?php echo get_post_meta($post->ID, 'image', true); ?>" /></a>
<?php echo get_post_meta($post->ID, 'image', true); ?>outputs the image URL you assigned to the post using the “image” custom field and its value (an image URL). -
Rest of the values I used are pretty standard.
<?php the_permalink(); ?>outputs the permalink URL,<?php the_title_attribute(); ?>and<?php the_title(); ?>output the title of the post.
