Is there a way to only do a section of code on a template if the post has just been published or updated?

What do I need to wrap around that code?

**UPDATE:**

I need to check if any of my custom-post types called "members" have been saved. The template I'm using to display the posts is single-members.php.

If the post has been saved, then on my single-members.php template, I need to call `get_template_part('geocode');` - **but only if the post has been saved**.

**I DON'T WANT THIS TO HAPPEN IN THE ADMIN AREA, THIS NEEDS TO HAPPEN FRONT-END OF THE WEBSITE. OBVIOUSLY THE ONLY THING I WANT TO DO IN THE ADMIN AREA IS TO CLICK PUBLISH/UPDATE.**

Here's what's in the geocode.php file:

    <?php

    {
        die('Could not connect: ' . mysql_error());
    }
    
    mysql_select_db("medicom_wp", $con);
    
    
        $company = get_field('company_name');
        $address = get_field('address');
        $city = get_field('city');
        $post_code = get_field('post_code');
    
        $sql = sprintf("select count('x') as cnt from markers where `name` = '%s'", mysql_real_escape_string($company));
        $row_dup = mysql_fetch_assoc(mysql_query($sql,$con));
        if ($row_dup['cnt'] == 0) {
            mysql_query("INSERT INTO markers (`name`, `address`, `lat`, `lng`, `type`) VALUES ('".$company."', '".$address.", ".$city.", ".$post_code."', '0.0', '0.0', '')");
