Simplifying Code for Custom Text for 'Previous/Next Post' Links in Single Posts

Existing code:
if ( ! function_exists( 'generate_content_nav' ) ) :
/**
* Display navigation to next/previous pages when applicable
*/
function generate_content_nav( $nav_id ) {
global $wp_query, $post;
// Don't print empty markup on single pages if there's nowhere to navigate.
if ( is_single() ) {
$previous = ( is_attachment() ) ? get_post( $post->post_parent ) : get_adjacent_post( false, '', true );
$next = get_adjacent_post( false, '', false );
if ( ! $next && ! $previous )
return;
}
// Don't print empty markup in archives if there's only one page.
if ( $wp_query->max_num_pages < 2 && ( is_home() || is_archive() || is_search() ) )
return;
$nav_class = ( is_single() ) ? 'post-navigation' : 'paging-navigation';
?>
<nav role="navigation" id="<?php echo esc_attr( $nav_id ); ?>" class="<?php echo $nav_class; ?>">
<h6 class="screen-reader-text"><?php _e( 'Post navigation', 'generate' ); ?></h6>
<?php if ( is_single() ) : // navigation links for single posts ?>
<?php
$prev_post = get_adjacent_post( false, '', true );
previous_post_link(
'<div class="nav-previous"><span class="prev" title="' . esc_attr( $prev_post->post_title ) . '">%link</span></div>',
esc_attr__( 'Previous', 'generatepress' )
);
$next_post = get_adjacent_post( false, '', false );
next_post_link(
'<div class="nav-next"><span class="next" title="' . esc_attr( $next_post->post_title ) . '">%link</span></div>',
esc_attr__( 'Next', 'generatepress' )
);
?>
<?php elseif ( $wp_query->max_num_pages > 1 && ( is_home() || is_archive() || is_search() ) ) : // navigation links for home, archive, and search pages ?>
<?php if ( get_next_posts_link() ) : ?>
<div class="nav-previous"><span class="prev" title="<?php _e('Previous','generate');?>"><?php next_posts_link( __( 'Older posts', 'generate' ) ); ?></span></div>
<?php endif; ?>
<?php if ( get_previous_posts_link() ) : ?>
<div class="nav-next"><span class="next" title="<?php _e('Next','generate');?>"><?php previous_posts_link( __( 'Newer posts', 'generate' ) ); ?></span></div>
<?php endif; ?>
<?php generate_paging_nav(); ?>
<?php do_action('generate_paging_navigation'); ?>
<?php endif; ?>
</nav><!-- #<?php echo esc_html( $nav_id ); ?> -->
<?php
}
endif; // generate_content_navGoal: changing linking texts to "Previous post" and "Next post" from "Post Title", without affecting the HTML "title" attribute of the 'a' tag (should still have title="Post Title").
Can this be simplified using filters instead of overwriting the whole function (as suggested by you)?
Hi there,
So instead of overwriting that function, we should be able to filter into the core WP code like this:
add_filter( 'next_post_link', function( $output, $format, $link, $post, $adjacent ) {
$next_post = get_adjacent_post( false, '', false );
return sprintf(
'<div class="nav-next"><span class="next" title="%1$s"><a href="%3$s">%2$s</a></span></div>',
esc_attr( $next_post->post_title ),
__( 'Next' ),
get_permalink( $next_post->ID )
);
}, 10, 5 );
add_filter( 'previous_post_link', function( $output, $format, $link, $post, $adjacent ) {
$prev_post = get_adjacent_post( false, '', true );
return sprintf(
'<div class="nav-previous"><span class="prev" title="%1$s"><a href="%3$s">%2$s</a></span></div>',
esc_attr( $prev_post->post_title ),
__( 'Previous' ),
get_permalink( $prev_post->ID )
);
}, 10, 5 );Let me know :)
Worked perfectly! Thanks again!
You're welcome :)
Based on this Tom code, how can I change the text written in Next and Prev? I tried but I didn't succeed ... I want a function for that.
Hi there,
if you want to simply to chenge the next prev labels - then you simply change the strings in these two lines:
__( 'Next' ),
and
__( 'Previous' ),
