Hello!

With the next code, in the WordPress admin, I can generate the value of the field "email-comercial-asociado" depending on the relationship field "comercial-expediente". But now, I want to do the same but when creating the post from a front-end form.

add_action( 'save_post', 'copy_relation_to_field_email_for_recomendado', 100, 3 );
function copy_relation_to_field_email_for_recomendado( $post_id, $post, $update ) {
if ( $post->post_status == 'publish' && $post->post_type == 'recomendado' ) {
$recomendado_id = $post_id;
// Get ID from CPT "comercial" parent of CPT "recomendado"
$comercial_id = toolset_get_related_post( $recomendado_id, 'comercial-expediente', 'parent');
$author_comercial_id = get_post_field( 'post_author', $comercial_id );
$author_coemrcial_email = get_the_author_meta( 'email', $author_comercial_id );
// Update custom field
update_post_meta( $post_id, 'wpcf-email-comercial-asociado', $author_coemrcial_email );
}
}

Thanks!

Hi Jesus,

Thank you for getting in touch. If the above code works on the backend, then the only thing you need to do is to use the Hook for our frontend form.

The Hook that is equivalent to this would be the one in the link below.

Thanks,

The first code run ok, but I modify it to use it with the front-end form and it doesn't work:

But I modify it to use it from the form and it doesn't work:

add_action('cred_save_data', 'copy_relation_to_field_email_for_recomendado_frontend',999,2);
function copy_relation_to_field_email_for_recomendado_frontend($post_id, $form_data)
{
// if a specific form
if ($form_data['id']==335)
{
if (isset($_POST['@comercial-expediente.parent']))
{
$recomendado_id = $post_id;
// Cogemos el ID del CPT comercial padre del recomendado
$comercial_id = toolset_get_related_post( $recomendado_id, 'comercial-expediente', 'parent');
$author_comercial_id = get_post_field( 'post_author', $comercial_id );
$author_coemrcial_email = get_the_author_meta( 'email', $author_comercial_id );
// add it to saved post meta
add_post_meta($post_id, 'wpcf-email-comercial-asociado', $author_coemrcial_email);
}
}
}

Hi Jesus,

I'm not seeing any reason why this shouldn't work.

Would you mind allowing me to have admin access to the site as well as a link to the page where you are testing this so that I can do a firsthand check ?

Thanks,
Shane

I have already found the error. The line of code to verify that the relationship field is defined is not correct.

if (isset($_POST['@comercial-expediente.parent']))

If I delete the line the field change is done correctly, but I need to evaluate if the relationship field is defined to avoid errors.

I need to know how the relationship field value is stored in the variable $ _POST

Any ideas to fix it? Thanks!

Hi Jesusm

I believe the . is replaced by an underscore.

Try using this below.

if (isset($_POST['@comercial-expediente_parent']))

If the above doesn't work then please try the one below.

if (isset($_POST['@comercial-expediente-parent']))

Failing both of these you can dump the post_data variable unto the page when you submit the form

var_dump($form_data);

Then you should be able to see the entire payload of the form data and see exactly what exactly is the identifier for the field.

Thanks,
Shane
