Hi,
is there a way to populate a CTP title from different custom fields?
I've tried to set up a text field with "post_title" ID, with this kind of value:
{mb_bien_taxonomy_type_bien} {mb_bien_taxonomy_type_offre_bien} T{mb_bien_nb_pieces_bien} {mb_bien_commune_bien}

but in the "all post view", the fields are not populated with the values. Hope that makes sense.
I've tried to search in the past post here but may not be searching the right terms...

Thanks in advance if you can point me in the right direction,
regards,
Jo

Hi,

Meta Box does not support adding the field ID variable to the post title like that. If you are familiar with coding, please follow this topic to know how to update the post title from the field value https://support.metabox.io/topic/adding-metabox-field-data-to-the-post-title

Let me know how it goes.

Thanks a lot!
It works, however, it doesn't if I try to add several fields. Is it possible to do that?
I wrote it :
```
function update_post_title( $post_id ) {
    // Get the field value
    $my_meta = rwmb_meta( 'nb_pieces_bien', 'type_offre_bien', $post_id );
```

Hi Jo,

You should get the field value separately and concatenate them later. For example:
```
$my_meta1 = rwmb_meta( 'nb_pieces_bien', '', $post_id );
$my_meta2 = rwmb_meta( 'type_offre_bien', '', $post_id );

$my_post = array(
    'ID' => $post_id,
    'post_title' => $my_post_title . ' ' . $my_meta1 . ' ' . $my_meta2,
);
```
