How to open link in a new tab using custom field in wordpress using php

Question

I'm trying to redirect all wordpress post permalinks to a custm field value instead of wordpress url with the below funciton:

function get_custom_permalink() {
global $wp_rewrite,$post;
$custom_field = get_post_meta($post->ID, 'my_custom_field', true);
$field =  $custom_field;
if (!empty($custom_field)) {
    return str_ireplace('<a', '<a target="_blank"', $field);
 } else {
    return false;
 }
}
add_filter('post_link', 'get_custom_permalink', 10, 4);

The function works great but I'm not able to open in a new tab do you have any suggestion? Thank you.
