Hello there, I created a shortcode to MB Frontend Submission like this below:
[mb_frontend_form id="celulas" post_fields="endereco,mapa,dia_da_semana,hora_celula,thumbnail" label_thumbnail="Foto da fachada" submit_button="Cadastrar célula" edit="false" allow_delete="false" post_status="publish" redirect="/perfil" confirmation="Muito obrigado"]
Then after submission of the form everything is ok except it using the WP user ID instead of Display name (image bellow)
I have setup the Custom Field as follow in image bellow:
The thing is, I couldn't figure a way to make it save as User Display Name instead of User ID.
