Introduction:

WordPress is a popular and user-friendly content management system that enables bloggers and website owners to publish and manage their content seamlessly. One of its key features is the ability to display posts in a loop, allowing users to showcase their content in a systematic and engaging manner. In this article, we will explore how to display any number of posts in a loop using WordPress and create a list of tag words associated with each post.

Step 1: Setting up WordPress Loop

Before we dive into the process of displaying posts in a loop, ensure that you have a functional WordPress installation with an active theme. WordPress provides built-in functions and template tags that simplify the process of displaying posts in a loop. To begin, navigate to the template file where you want to display the posts.

Step 2: Understanding The Loop

The WordPress Loop is the core concept responsible for fetching and displaying posts from the database. To initiate the loop, add the following code within your template file:

<?php if (have_posts()) : while (have_posts()) : the_post(); ?>
<!-- Your post content goes here -->
<?php endwhile; endif; ?>

The above code checks if there are any posts available in the database. If posts are found, it starts the loop and iterates through each post, allowing you to display content within the loop.

Step 3: Displaying Post Content

Within the loop, you can access various elements of each post, including the title, content, date, author, and tags. To display the title and content of each post, add the following code inside the loop:

<h2><?php the_title(); ?></h2>
<div><?php the_content(); ?></div>

Step 4: Listing Tags

To list the tag words associated with each post, we will retrieve the post's tag information using the get_the_tags() function. This function returns an array of tag objects for the current post. To display the tags, add the following code within the loop:

<?php
$tags = get_the_tags();
if ($tags) {
echo '<ul class="post-tags">';
foreach ($tags as $tag) {
echo '<li class="tag">' . $tag->name . '</li>';
}
echo '</ul>';
}
?>

The above code checks if the post has any tags and then iterates through them to list each tag as a separate list item within an unordered list.

Step 5: Controlling the Number of Posts

To control the number of posts displayed on a page, you can use the pre_get_posts filter in WordPress. By adding this filter to your theme's functions.php file, you can modify the number of posts displayed per page. For example, to show 10 posts per page, use the following code:

function custom_posts_per_page($query) {
if ($query->is_archive() && $query->is_main_query()) {
$query->set('posts_per_page', 10);
}
}
add_action('pre_get_posts', 'custom_posts_per_page');

Conclusion:

In this article, we've explored how to display any number of posts using the WordPress loop and how to create a list of tag words associated with each post. The WordPress loop is a powerful tool that allows users to present their content in an organized and visually appealing manner. By following the steps outlined in this guide, you can effortlessly display posts and enhance your website's user experience while effectively showcasing relevant tag words for each post.
