I am writing a code where I can get notifications everytime a post is edited on a custom post type.
It is working fine, but ACF's repeater field is not rendering its subfields on the email.
I wonder what I could be doing wrong. The email comes with the exact number of rows in the post, only the fields are not being displayed.
Everything else seems to be working fine.
function send_mails_on_update( $new_status, $old_status, $post )
{
if ( $new_status != $old_status or 'form_caravanas' !== get_post_type( $post ) )
return 'text/html';
$subscribers = get_users( array ( 'role' => 'administrator' ) );
$emails = array ();
foreach ( $subscribers as $subscriber )
$emails[] = $subscriber->user_email;
$nome = get_field('nome', $post);
$sobrenome = get_field('sobrenome', $post);
$ddd_celular = get_field('ddd_celular', $post);
$email = get_field('email', $post);
$nome_da_igreja = get_field('nome_da_igreja', $post);
$tipo_de_transporte = get_field('tipo_de_transporte', $post);
$cidade_e_estado_de_origem = get_field('cidade_e_estado_de_origem', $post);
$repeater = get_field('participantes', $post);
$participantes = '';
if( have_rows('participantes', $post) ):
while( have_rows('participantes', $post) ): the_row();
$nome_participante = the_sub_field('nome', $post);
$sobrenome_participante = the_sub_field('sobrenome', $post);
$ddd_celular_participante = the_sub_field('telefone', $post);
$email_participante = the_sub_field('email', $post);
$participantes.= sprintf( '<ul>
<li>Nome: ' . $nome_participante . '</li>
<li>Sobrenome: ' . $sobrenome_participante . '</li>
<li>Celular: ' . $ddd_celular_participante . '</li>
<li>Email: ' . $email_participante . '</li>
</ul>' ); endwhile; endif;
$participantes.= '';
$body = sprintf( '<html><head><link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" integrity="sha384-BVYiiSIFeK1dGmJRAkycuHAHRg32OmUcww7on3RYdg4Va+PmSTsz/K68vbdEjh4u" crossorigin="anonymous"></head><body>

wp_mail( $emails, 'A caravana "' . get_the_title( $post ) . '" foi atualizada!', $body );
}
First, make sure that participantes is the name of the repeater. Then, remove the $post variable in every the_sub_field().
Change
$nome_participante = the_sub_field('nome', $post);
$sobrenome_participante = the_sub_field('sobrenome', $post);
$ddd_celular_participante = the_sub_field('telefone', $post);
$email_participante = the_sub_field('email', $post);
To
$nome_participante = the_sub_field('nome');
$sobrenome_participante = the_sub_field('sobrenome');
$ddd_celular_participante = the_sub_field('telefone');
$email_participante = the_sub_field('email');
You already mentioned which repeater's values to fetch(and you are in that repeater's while loop) so you don't need to insert that again on the sub field.
Also, you might need to use get_sub_field() and not the_sub_field(). The difference is that the_sub_field() echoes the value and get_sub_field() doesn't.
