WP: 5. Guide to Implement Next Previous Post Navigation in WP

 

Today I ran into a problem, I need to implement to post previous and next navigation and found this solution.

And nonetheless, It's better to fix the thing with some bunch of code rather than uploading one more bulky plugin on your website that will end up making your site heavy.

Just follow the steps below and avoid heading up into any malicious or bulky plugin for this particular problem from now on forever.

Step 1: Go ahead and paste the following code in your active theme's single.php

//To return the URL of the previous page, use the following php code:

$prev = get_permalink(get_adjacent_post(false,'',false));

//To return the URL of the next page, use the following php code:

$next = get_permalink(get_adjacent_post(false,'',true));

//To use them, simply echo the variables $prev and $next where you need them.

<a href="<?php echo $prev; ?>">Previous Post</a> and the 

<a href="<?php echo $next; ?>">Next Post</a>

//What if there isn’t a previous or next post?

//Since our functions will automatically return either the adjacent post’s URL if there is one or the current post’s own URL if you’re on the first or last post. Use the following code to make it conditional whether to display the previous or next post link:

<?php $prev = get_permalink(get_adjacent_post(false,'',false)); 

    if ($prev != get_permalink()) { ?>

        <a href="<?php echo $prev; ?>">Previous Post Only Displaying If Available</a>

<?php } ?>

//There you have it — hope it saved you a headache. 

Now Cheers !😊
