Forms: Field visibility rules on a hidden field

[Natali_Talevski]

Hi guys,

Is there a way to stop a hidden field on a form from prepopulating when a certain value is selected? I'm essentially looking to replicate the way the visibility rules will hide a field, for example, a form has Country and State; if Canada is selected, hide the State field.

Can you do something similar with a hidden field? The hidden field I'm trying to block prepopulates with a timestamp - I want this timestamp not to pass through if a certain value is selected in the form.

Thanks

Natali

Hi Natali,

You will have to use some Javascript to do this.

MktoForms2.whenReady(function(form){
  form.onSubmit(function(form){
    if ( form.getValues()['YourVisibleFieldName'] == 'YourCertainValue' ) {
      form.setValues({
        'YourHiddenFieldName' :null
      });
    }
  });
});

Thanks so much. I'll give it a go
