How to Change Previous and Next Link Text from a Single Blog Post?

Sometimes you might need to change the navigation (Previous and Next ) links to text on the single blog post. Default strings for navigation links will be – Previous Post and Next Post. You can change it using the following filters.

1. Replace default navigation strings with next/previous post titles

The following filter will fetch the Previous and Next post title and will display them as navigation links.

add_filter( 'astra_single_post_navigation', 'astra_change_next_prev_text' );

/**
 * Function to change the Next Post/ Previous post text.
 *
 * @param array $args Arguments for next post / previous post links.
 * @return array
 */
function astra_change_next_prev_text( $args ) {
	$next_post = get_next_post();
	$prev_post = get_previous_post();
	$next_text = false;
	if ( $next_post ) {
		$next_text = sprintf(
			'%s <span class="ast-right-arrow">→</span>',
			$next_post->post_title
		);
	}
	$prev_text = false;
	if ( $prev_post ) {
		$prev_text = sprintf(
			'<span class="ast-left-arrow">←</span> %s',
			$prev_post->post_title
		);
	}
	$args['next_text'] = $next_text;
	$args['prev_text'] = $prev_text;
	return $args;
}

2. Replace default navigation strings with custom text

The following filter will replace Previous and Next links with your custom text. You can replace your text with – ‘My Previous Custom Text’ and ‘My Next Custom Text’ in the following filter code.

add_filter( 'astra_single_post_navigation', 'astra_change_next_prev_text' );
 
/**
 * Function to change the Next Post/ Previous post text.
 *
 * @param array $args Arguments for next post / previous post links.
 * @return array
 */
function astra_change_next_prev_text( $args ) {
    $next_post = get_next_post();
    $prev_post = get_previous_post();
    $next_text = false;
    if ( $next_post ) {
        $next_text = sprintf(
            '%s <span class="ast-right-arrow">→</span>',
            'My Next Custom Text'
        );
    }
    $prev_text = false;
    if ( $prev_post ) {
        $prev_text = sprintf(
            '<span class="ast-left-arrow">←</span> %s',
            'My Previous Custom Text'
        );
    }
    $args['next_text'] = $next_text;
    $args['prev_text'] = $prev_text;
    return $args;
}

Note: Add the above code in the child theme’s functions.php file.
