Several questions regarding online ordering form

Hi everyone.

I'm currently working on a form for a food home delivery service.
I created a multi page form to split the "address" section from the "ordering" section.

I'm stuck now at some points and was wondering if you guys could maybe help me out.

1.)
My first question is regarding the address field.
Is there any possibilty to realize the zip code input with a dropdown menu because the delivery service is only delivering to some defined zip codes. That's why I would like to change the "open" text field to a dropdown menu.

2.)
For the food ordering I created 3 fields, "product", "quantity" and "option".
Is there any way to link the "option" text field with the equal "product" field?
Because the "option" fields are not listed in the "ordering" table in the confirmation email the admin receives after sending the form.

3.)
Is there any way to categories the products in the "product" dropdownmenu?
For example:
Starter:
- Product 1
- Product 2
Main:
- Product 3
- Product 4
Dessert:
- Product 5
- Product 6

4.)
And the last question is regarding the confirmation text the costumer should see after sending the form. Unfortunately I can't see anything after sending...

I hope I could describe my questions clearly.
For better understanding, here is a link to my current ordering form (sorry, the whole form is in german):

Thanks in advance for your help.

Hey Rob. Thank you for your quick reply.

Regarding 1 - I think I found a workaround for that. I created a zip code selection as the first step of the form. That is the easiest way for that at the moment I think.
Is there maybe any way to "transport" the zip code selection from step one to the zip code field of the address field in step 2?

Regarding 2 - I found the "option" field for the products. But there is now way to change the "style" of that field to a text file were the costumer can write down his own option, right? I'm talking abou options like "without onions" etc.
I think it is too difficult to create a options dropdown menu for a food delivery service.

Regarding 3 - Great idea... I will try that :)

Regarding 4 - After sending the form I only see the 100 % "status bar", but nothing else. In my options I created a comfirmation message, but I can't see that.
In the Wordpress backend / form preview mode, the confirmation message is displayed correctly after sending the form.

I can't explain why you wasn't able to reach the server but here is the link to the form again.
Hope it will work this time.

Hi Rob.

Thanks again for you quick help.

Regarding 1 - I found a snippit posted by wsnider28 (http://www.gravityhelp.com/forums/topic/populate-field-from-previous-field#post-48722)

and edited the code as written in the descriptions:
- form ID to "2"
- page number to "2" (target field is on the second page)
- target field ID to "14" (address field on the second page)
- source field ID to "input_2_25" (radio buttons on the first page)

but it isn't working at all. I also checked the "Allow field to be populated dynamically" option of the address field on the second page but didn't fill out the parameter boxes yet. I don't really know how to do that.

I'm sorry but my coding skills are quiet low, so maybe you can help me with that.

<?php

// update "108" to the ID of your form
add_filter("gform_pre_render_2", "populate_previous_page_data");
function populate_previous_page_data($form){

    $page_number = rgpost("gform_target_page_number_{$form["id"]}");
    $page_number = !is_numeric($page_number) ? 2 : $page_number;

    foreach($form['fields'] as &$field) {

        if($field['id'] != 14) // update "15" to the ID of the field you wish to be populated;

        $field_page = rgar($field, 'pageNumber');

        if($page_number > $field_page)
            continue;

        // update this to the ID of the field whose value you wish to call
        // '16.3' = example, first name of a Name field
        // '16.6' = example, last name of a Name field
        $field['defaultValue'] = rgpost('input_2_25'); 

    }

    return $form;
}

Regarding 2-4 - I couldn't solve everything yet, but I think I'm fine so far with all your advices.

Thank you.
Best regards,

Dominik, like I said above, because of how the address field is structured, you won't be able to use built-in dynamic population. If you had split fields (independent fields) that make up the Address then you could pass the Zip into a single line text field.

Glad you are making some progress with everything though. Menu/Food/Restaurant Ordering Forms are always beasts!
