Looking in the docs I found to use this:

<?php
 
function my_acf_update_value( $value, $post_id, $field  )
{
    $value = "Custom value";
 
    // do something else to the $post object via the $post_id
 
    return $value;
}
 
// acf/update_value - filter for every field
add_filter('acf/update_value', 'my_acf_load_field', 10, 3);
 
// acf/update_value/type={$field_type} - filter for a specific field based on it's type
add_filter('acf/update_value/type=select', 'my_acf_load_field', 10, 3);
 
// acf/update_value/name={$field_name} - filter for a specific field based on it's name
add_filter('acf/update_value/name=my_select', 'my_acf_load_field', 10, 3);
 
// acf/update_value/key={$field_key} - filter for a specific field based on it's name
add_filter('acf/update_value/key=field_508a263b40457', 'my_acf_load_field', 10, 3);
 
?>

However, adding just that to my functions.php causes a bunch of errors when trying to publish a post:

Warning: call_user_func_array() expects parameter 1 to be a valid callback, function 'heading2' not found or invalid function name in /home/movies9/public_html/msv6/wp-includes/plugin.php on line 199

If I just want this to effect the “heading2” custom field. How would I edit it?
