Hi,

We will answer both of your tickets here.

So our team add the navigation using the following code :

add_action( 'woocommerce_after_single_product_summary', 'woocommerce_output_navigation_link', 10 );
function woocommerce_output_navigation_link(){
    
    
    ob_start();?>
<div class="single_product_navigation"><!--?php $next = get_permalink(get_adjacent_post(false,'',true)); if ($next != get_permalink()) { ?--><a href="<?php echo esc_url($next); ?>" class="previous_product"><!--?php echo __('Previous', 'thefoxwp'); ?--></a><!--?php } ?--><!--?php $prev = get_permalink(get_adjacent_post(false,'',false)); if ($prev != get_permalink()) { ?--><a href="<?php echo esc_url($prev); ?>" class="next_product"><!--?php echo __('Next', 'thefoxwp'); ?--></a><!--?php } ?--></div>
<!--?php
$output = ob_get_clean();
echo !empty( 6;output ) ? $output : '';
        
}

so what you would need to do is remove this action

remove_action( 'woocommerce_after_single_product_summary', 'woocommerce_output_navigation_link', 20 );

and re-use the same code we sent 

add_action( 'woocommerce_before_single_product', 'new_woocommerce_output_navigation_link', 1 );
function new_woocommerce_output_navigation_link(){
    
    
    ob_start();?>
<div class="single_product_navigation"><!--?php $next = get_permalink(get_adjacent_post(true,'',true)); if ($next != get_permalink()) { ?--><a href="<?php echo esc_url($next); ?>" class="previous_product"><!--?php echo __('Previous', 'thefoxwp'); ?--></a><!--?php } ?--><!--?php $prev = get_permalink(get_adjacent_post(true,'',false)); if ($prev != get_permalink()) { ?--><a href="<?php echo esc_url($prev); ?>" class="next_product"><!--?php echo __('Next', 'thefoxwp'); ?--></a><!--?php } ?--></div>
<!--?php
$output = ob_get_clean();
echo !empty( 6;output ) ? $output : '';
        
}

This should put the navigation on the top and make it in the same category only.

Usually our team doesn't provide code snippet like this but it seems that our devs had some free time.

Hello,

I am sorry but I don't know, I think you are supposed to use the code they give us in your child theme functions.php

If you need customization please contact https://wpbuilders.co/request-service/

Sorry for not being able to help you this time.

Best regards

Hello Jfung,

Try to see if there isn't an error in the code when you copy / paste it.

We had some conversion errors when pasting code in the forum threads in the past, that might be the source of the error.

Sorry to not being able to help you more than that

Do not hesitate to contact us if you have more questions.

Have a nice day!

Best Regards.
