Hi Laurent,

I just saw your post about calculating the sum of a number field for a CPT and was wondering if you got it to work and if you could please share the code with me. I am not a programmer and am having a hard time figuring it out.

My custom post type is ‘investment_project’
Number field is ‘dashboard_value’

I need to show the sum of ‘dashboard_value’ through a shortcode in my home page.

Therefore, my code should look like this?:

function get_total_investment_value($query_args) {
$total = 0;
$posts = get_posts($query_args=’-1′);
foreach ($posts as $post) {
$total += get_field(‘dashboard_value’, $post->ID);
}
return $total;
}

function show_total_investment_value() {
print get_total_investment_value(array(‘post_type’=>’investment_project’));
}
add_shortcode(‘show_the_total_investment_value’, ‘show_total_investment_value’);

And do I just add this directly as is in the functions.php of my child theme?

Any help at all will be greatly appreciated!

Thank you
