Wordpress: Check if there are previous posts before displaying link

Question

I\'m using the following code to display a \'previous posts\' link on my Wordpress blog.

     

            

                
&         


        

Answer 1

Just to be clear:

Colin's answer isn't correct in my opinion. get_previous_post is not deprecated, previous_post is.

http://codex.wordpress.org/Function_Reference/get_previous_post http://codex.wordpress.org/Function_Reference/previous_post

For me the use of get_next_post works still fine for me.

if(get_next_post()) {  }
if(get_previous_post()) {  }

Answer 2

None of the answers worked for me. I solved it this way:

$next = get_permalink(get_adjacent_post(false,'',false)); //next post url
$prev= get_permalink(get_adjacent_post(false,'',true)); //previous post url
<?php if (get_the_permalink()!=$prev): ?>
    <a href='<?php echo $prev ?>'>Previous</a>
<?php endif; ?>
<?php if (get_the_permalink()!=$next): ?>
    <a href="<?php echo $next ?>">Next</a>
<?php endif; ?>

Answer 3

for people checking this in 2013, get_previous_post has been depreciated.

http://codex.wordpress.org/Next_and_Previous_Links http://codex.wordpress.org/Function_Reference/previous_post

I used to use this :/

if(get_next_post()) { echo 'next'; }
if(get_previous_post()) { echo 'last'; }

But now I use this :)

if(get_next_posts_link()) { echo 'next'; }
if(get_previous_posts_link()) { echo 'last'; }

Answer 4

You can try something like this

<?php
    if($link = get_previous_posts_link()) {
        echo '<ul><li>'.$link.'</li></ul>';
?>

get_previous_posts_link returns null (falsy value) if there isn't any previous post.
