Message:

I am currently using the WordPress previous_post_link and next_post_link, which work as expected. The issue is that I have imported tons of posts via CSV file, so now most posts have the same date/timestamp, and WP doesn't pick the right prev/next post as it is based on date by default I believe.
I have searched other answers which show how to search the ID, but I can't seem to implement it into a link, it only returns a plain ID. For sure I'm getting it wrong as I do not have much PHP knowledge.

I am using this code:

<div class="prev"><?php previous_post_link( '%link', '%title', TRUE ); ?>&nbsp;</div>

<div class="next"><?php next_post_link( '%link', '%title', TRUE ); ?>&nbsp;</div>

I have found the code below but I don't know how to turn it into the code format above.

<?php

function get_previous_post_id( $post_id ) {

    global $post;

    $oldGlobal = $post;

    $post = get_post( $post_id );

    $previous_post = get_previous_post();

    $post = $oldGlobal;

    if ( '' == $previous_post ) 

        return 0;

    return $previous_post->ID; 

} 



echo get_previous_post_id( $current_id );

An answer that can provide a working code is much appreciated. Thanks

My Answer:
You can modify your code to use the function `get_previous_post_id` to get the previous post ID and then use that ID to generate the link. Here's how you can do it:

php

$previous_post_id = get_previous_post_id( $post->ID );
if ( $previous_post_id ) {
$previous_post_link = get_permalink( $previous_post_id );
$previous_post_title = get_the_title( $previous_post_id );
echo '' . $previous_post_title . '';
}
?>
 

$next_post_id = get_next_post_id( $post->ID );
if ( $next_post_id ) {
$next_post_link = get_permalink( $next_post_id );
$next_post_title = get_the_title( $next_post_id );
echo '' . $next_post_title . '';
}
?>
 

Make sure to add the `get_next_post_id` function as well:

php
function get_next_post_id( $post_id ) {
global $post;
$oldGlobal = $post;
$post = get_post( $post_id );
$next_post = get_next_post();
$post = $oldGlobal;
if ( '' == $next_post )
return 0;
return $next_post->ID;
}


This code will get the previous and next post IDs based on the current post ID and then generate the links for them.
