Hello,
I have a form in frontend

The code below is working well to calculate price and save it in database :

function my_acf_update_totalprice( $post_id )
{

// bail early if not a reservation post
if( get_post_type($post_id) !== ‘reservation’ ) {
return;
}

$total = get_field( ‘prix_chambre_simple’, $post_id) * get_field( ‘nombre_de_chambres_simples’, $post_id );
$value = $total;
$field_name = “prix_total”;
update_field($field_name, $value, $post_id);
}
add_action(‘acf/save_post’, ‘my_acf_update_totalprice’);

I want to add a total_field before the submit button. How to display the total in this field before form is submitted ?

Can you help me to do it please ?

Thank you

Hi @dweb

For something like that, you need to use JavaScript code to get the values and calculate the total. This page should give you more idea about it: http://stackoverflow.com/questions/2157252/get-total-of-all-input-values-with-jquery.

because this is more related to JavaScript and jQuery, kindly visit their community for further support.

I hope this helps 🙂
