Merge tags in multistep Gravity Form?

Question

I want to use a multi-step form where the user enters their name in step one, then on step two the form will say "Hello, [name]" with the rest of the content and steps to follow.

Any ideas?

EDIT: I want to use data entered in step one on step 2. Reading GF documentation I think something like {[Field Name]:[field_id]} should work, but it does not. Digging further I found that this would only work once a form has been submitted already. So my question is, is there a way that will enable me to use the merge tags within the current form from data being submitted in a previous step?

Answer 1

This is possible with Live Merge Tags, a feature of Gravity Forms Populate Anything.

If you're looking to get your hands dirty with some code, Gravity Forms has an example of how this might work with a snippet on their docs for the gform_pre_render filter:

Answer 2

It's pretty easy to extend the GF_Field_HTML class to do this then register it at the gform_loaded action. You'll want to override the get_field_input method and where the original has this:

$content = GFCommon::replace_variables_prepopulate( $content );

your replacement should have this:

$lead = GFFormsModel::get_current_lead();
$content = GFCommon::replace_variables( $this->content, $form, $lead );
