Yeah, ‘ I’ve ma ed a mistake with that example code. It should be
'post_type' => 'post',
post_status' => 'publish'
I think I solved my problem with using:
wp_redirect(add_query_arg( 'error', 'true', get_permalink($submit_page_id)));
in the _action_ssd_acf_submit_post_pre_save function in the following hook:
add_action( 'acf/pre_save_post', '_action_ssd_acf_submit_post_pre_save', 1 );
This way I don’t use the return of the acf_form() function and redirect to the same page with the form but the parameters in the URL which I can get to show the error notice on that page.
Don’t know if this is the right way though.
