Hi! I'm trying to format a price number to get the text field look like "4 200 000" in the frontend.
I try to use the custom sanitize callback as you mentioned here

I added formatage_prix in the callback field of my price text field and this code:

<?php 
add_filter( 'rwmb_meta_boxes', function( $meta_boxes ) {
    $meta_boxes[] = [
        'title' => 'formatage_prix',
        'fields' => [
            [
                'type'              => 'text',
                'id'                => 'prix_vente_bien',
                'name'              => 'Prix de vente',
                'sanitize_callback' => 'formatage_prix',
            ]
        ],
    ];
    return $meta_boxes;
} );
function formatage_prix( $value, $field, $old_value, $object_id ) {
    $number = rwmb_meta( 'prix_vente_bien' );
 // French notation
 $nombre_format_francais = number_format( $number, 2, ',', ' ' );
 echo $nombre_format_francais;
}

It doesn't work. Would you be able to help me figure that out? THanks a lot and happy new year!

I don't see how to delete my post. SO here is how I finally made it work:

<?php
$number = rwmb_meta( 'prix_vente_bien' );
$nombre_format_francais = number_format( $number, 0, ',', ' ' );
echo $nombre_format_francais;
?>

in the output field. I still wish I could make it work with the sanitize callback though, so if you can spot my mistake I would be very grateful!

Hello Jo,

To use the sanitize callback, please read more on the documentation https://docs.metabox.io/sanitization/#custom-sanitize-callback

The callback function will look like this

function formatage_prix( $value, $field, $old_value, $object_id ) {
 // French notation
 $value = number_format( $value, 2, ',', ' ' ); // use $value to get the field value
 return $value; // and return the field value after formatting
}
