如何将PHP代码放入wordpress分页功能（previous_post_link，next_post_link等）中？

Question

I want to put PHP code in my pagination:

<?php next_post_link('%link','<div class="nav-next" title="<?php the_title();?>">Next Post</div>')?>

However, the result is I got a text: "" instead of the real title post when I hover my pagination link.

How to get my php code works inside that wordpress parameter?

Thanks.

Answer 1

There is no need for get_the_title. next_post_link already makes the title of the next post available, via %title

 next_post_link( '%link', '<div class="nav-next" title="%title">Next Post</div>' )

Answer 2

Use string concatenation and get_the_title() which returns the value rather than echoing it:

<?php 
  next_post_link(
           '%link',
           '<div class="nav-next" title="'.get_the_title().'">Next Post</div>'
 )?>
