Only show if var exists

[OhTheNoes]

I apologize in advance for any misuse of terminology. I find that I am rather ignorant in such things.

 

I'm working on a WordPress theme. Specifically on the part that shows the "next: link-to-next-post" and "previous: link-to-prev-post" links.

 

Here is the code that I have:

<?php
  $nextvar=next_post_link('%link');
  $prevvar=previous_post_link('%link');
?>

<?php if (isset($nextvar)) { ?>
<h3>Next</h3>
<p><?php next_post_link('%link'); ?></p>
<? } ?>

<?php if (isset($prevvar)) { ?>
<h3>Previous</h3>
<p><?php previous_post_link('%link'); ?></p>
<? } ?>

 

The first part intends to check if the links exist. And this works fine.

 

However, the only output I'm getting are the values of $nextvar and $prevvar. The headers are nonexistent. What's wrong?

 

Any help is much appreciated, and I thank you in advance.

Your code works for me, but only if I put the full php tag '<?php' not just '<?'.. I didn't use the next_post_link() functions, I just made each of those variables equal to a string, so as to force the set or unset state. And echoed accordingly.. So just try changing the php tags before the ending curley braces.

Oh shoot, I can't believe I missed that. Shouldn't have been working at 5am really =/

 

Thank you, Denno!
