I am trying to change the functionality of the arrows so that they will only cycle through the current portfolio category rather than all portfolio posts. I have found the following code on other similar support threads, but when I try it, the arrows do not render at all.

function x_entry_navigation() {

  $stack = x_get_stack();

  if ( $stack == 'integrity' ) {
    $left_icon  = '<i class="x-icon-chevron-left" data-x-icon=""></i>';
    $right_icon = '<i class="x-icon-chevron-right" data-x-icon=""></i>';
  } else {
    $left_icon  = '<i class="x-icon-arrow-left" data-x-icon=""></i>';
    $right_icon = '<i class="x-icon-arrow-right" data-x-icon=""></i>';
  }

  $is_ltr    = ! is_rtl();
  $prev_post = get_adjacent_post( true, '', false );
  $next_post = get_adjacent_post( true, '', true );
  $prev_icon = ( $is_ltr ) ? $left_icon : $right_icon;
  $next_icon = ( $is_ltr ) ? $right_icon : $left_icon;

  ?>

  <div class="x-nav-articles">

    <?php if ( $prev_post ) : ?>
      <a href="<?php echo get_permalink( $prev_post ); ?>" title="<?php __( 'Previous Post', '__x__' ); ?>" class="prev">
        <?php echo $prev_icon; ?>
      </a>
    <?php endif; ?>

    <?php if ( $next_post ) : ?>
      <a href="<?php echo get_permalink( $next_post ); ?>" title="<?php __( 'Next Post', '__x__' ); ?>" class="next">
        <?php echo $next_icon; ?>
      </a>
    <?php endif; ?>

  </div>

  <?php

  }

Hi there,

Can you enable WP_DEBUG mode? You can do this by opening wp-config.php and adding
define( 'WP_DEBUG' , true ); just above /* That's all, stop editing! Happy blogging. */ For example:

define('WP_DEBUG', true);

/* That's all, stop editing! Happy blogging. */

When you revisit the page with the white screen, you should have some error output describing the issue in more detail.

I have done that. But I didn’t say anything about a white screen? The arrows do not appear everything else is fine.

Hi there,

Your stack is ethos while the code has the condition for integrity. Hence, it will not display. Try changing this line,

if ( $stack == 'integrity' ) {

to this,

if ( $stack == 'ethos' ) {

It was originally made for ethos, the one you copied could be custom code for integrity.

Thanks!

[rosstm]

No my stack is integrity. I have tried both just for fun. Doesn’t work.

Any other ideas?

Hi there,

In that case, you don’t need to add this custom code. Integrity has its own nav arrows along with the breadcrumbs. But, I just found out that it’s only applicable for the built-in post type and taxonomy.

Some did it here http://stackoverflow.com/questions/10376891/make-get-adjacent-post-work-across-custom-post-types

But that is just for post type’s query, custom taxonomy like portfolio category isn’t even included. Hence, it’s a long customization in which I can’t cover. You may hire a developer that could do it.

This is not a theme limitation, but WordPress’s function limitation ( https://codex.wordpress.org/Function_Reference/get_adjacent_post )

Thanks for understanding.
