Hi @phylaxis,

I have a custom validation message save in custom field settings.
It’s maybe not the best solution but it’s works fine for me!

add_action('acf/render_field_settings', '_pit_add_field_setting_for_error_message');
function _pit_add_field_setting_for_error_message( $field ) {

    $args = array(
        'type' => 'text',
        'label' => 'Erreur formulaire',
        'name' => 'error_form',
        'instructions'	=> 'Erreur affiché a l\'utilisateur lors du remplissage du formulaire',
        'required' => 0,
        'default_value' => "Veuillez remplir ce champ"
    );
    acf_render_field_setting($field, $args, false);

}

add_filter('acf/validate_value', '_pit_acf_form_error_message', 10, 4);
function _pit_acf_form_error_message( $valid, $value, $field, $input ){

    if(!$valid)
        $valid = $field['error_form'];

    return $valid;

}

The first hook set the field and the second one print the error if the field is not valid. It’s works for me in AJAX form. I hope this code will help you. If you have a best way to to it I’m more than interrested!

I have try to set the field only when is required but it was a fail for me.. It’s works only when the field is save one time.

Sorry @pooledge I have try with the basic uploader and it’s doesn’t works for me too.

Thanks! 😉
