What does a Loop mean to a Blogger in WordPress
Loop is a very important function of WordPress. It’s basically like a PHP code that you are using in WordPress when you’re displaying posts. So if you have a page and you want to have ten blog posts displayed, this is a sort of process that says “On this page they’re going to be 10 blog post displayed” in a sort of queries where the system doesn’t need to get those posts there. And there are obviously tags that are specifically used within the posts or within the loop to get to function.
So before the loop goes into action, WordPress verifies that all the files it needs are present, collects all the default settings in the dashboard under Settings. It will fetch the data only that the users are asking for instead of fetching everything which is pretty essential to ensure fast page loading in WordPress. After all, each query to the database does take some time! The information from the database is stored in the variable which is used in the loop. The loop uses this variable and displays the content whatever it may be, blog past or page.
How does a loop work?
The loop starts with code that checks to see if the current page is supposed to display a listing of multiple posts or a single post or page. If the page is supposed to list blog posts then it will list out a title and excerpt for each post which can be customized to display featured images or other content. If the page is a single page or single post then the loop will just display the content for that page.
A basic loop to display a blog list
<?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?> <h2><?php the_title() ;?></h2> <?php the_post_thumbnail(); ?> <?php the_excerpt(); ?> <?php endwhile; else: ?> <p>Sorry, no posts to list</p> <?php endif; ?>
What does the loop do for pages that don’t exist?
If no posts are available or someone accesses a page that does not exist, the loop has an option to display a custom message informing the visitor there are no posts or the page does not exist (similar to what a 404 page does except customized to specific types of content).
Can you use multiple loops for one-page display?
There are also ways that you can use multiple loops on one page to display different types of content or format content in different ways. For example, you can have the latest blog post with a featured image display larger at the top of the site and then have older posts listed below with just a title and excerpt.
What can the Loop Display?
There are a number of elements that the loop can display, such as the title, excerpt, main content. You can see a list of these common functions along with a short description and a link to more information about each function. The loop can also use conditional statements to display different content based on a number of factors.
Loop is a very powerful function and a very important aspect of WordPress blogs. It’s impossible to build a WordPress site without using the WordPress loop. However, it can also be greatly customized using a range of tags, conditionals, and the WP_Query function.
