Vertical Response - got a cURL set-up working with a GF hook

Wasn't able to post to the existing Vertical Response post, so opened a new one. This isn't a plugin add-on, so not super elegant and requires a little more sleuthing in your own set-up, but is working for us using cURL.

I used the cURL part of this solution about a year ago, inspired by this information:
http://www.focal55.com/blog/vertical-response-tutorial-auto-submit-contact-information

To integrate that into a Gravity Form, wrote a function that can be added to the theme functions.php file and used by the GF post submission hook:
http://www.gravityhelp.com/documentation/page/Gform_post_submission

Things you need to know to make this work:
* Your Vertical Response form id
* Gravity Form field ids (findable in the blue title bar of each field when editing your form)

Add this function to your theme's functions.php file:
http://pastebin.com/M5KMtYUA

Notes:
* You don't have to send all of the gf fields to VR, just put the ones you want in the $postFields
* The gravity form (gf) fields that you're wanting to post to VR need to match up to fields in a VR opt-in form
* Just because you have xyz field in your VR general field list doesn't mean it will take it from your gf. The VR opt-in form has to have the fields you want to post to in it or it will cause an invalid form error from VR
* If it's successfully posting with cURL but not showing up in VR (check the $response form output and post - might be an invalid form error)- you may need to make a new opt-in form instead of using an existing one
* The gf field ids need to be in quotes when defined if you reference something like a checkbox: $gf_field_id_optin = '11.1';

If you work out an improvment to this or have a better approach, please share!

Thanks!

Thanks also from me! I'm using this now and it works a treat.

Does anyone know how we could grab the gform fields by name (rather than hardcoding IDs from a particular form) so that this same function could be used across many different forms?

You can access the form data with the array $form, and the fields specifically with $form['fields'].

Then you could do a loop through each field and look for type=email.

Here is the output of just $form['fields'][8] which is the email field in a form I'm using.

adminLabel =>
adminOnly =>
allowsPrepopulate =>
defaultValue =>
description =>
content =>
cssClass => gf_left_half
errorMessage =>
id => 9
inputName =>
isRequired => 1
label => Email
noDuplicates =>
size => medium
type => email
postCustomFieldName =>
displayAllCategories =>
displayCaption =>
displayDescription =>
displayTitle =>
inputType =>
rangeMin =>
rangeMax =>
calendarIconType =>
calendarIconUrl =>
dateType =>
dateFormat =>
phoneFormat =>
addressType =>
defaultCountry =>
defaultProvince =>
defaultState =>
hideAddress2 =>
hideCountry =>
hideState =>
inputs =>
nameFormat =>
allowedExtensions =>
captchaType =>
page_number =>
captchaTheme =>
simpleCaptchaSize =>
simpleCaptchaFontColor =>
simpleCaptchaBackgroundColor =>
failed_validation =>
productField =>
enablePasswordInput =>
maxLength =>
enablePrice =>
basePrice =>
calculationFormula =>
calculationRounding =>
enableCalculation =>
disableQuantity =>
inputMask =>
inputMaskValue =>
formId => 3
pageNumber => 1
descriptionPlacement => below
validation_message =>
9
adminLabel =>
adminOnly =>
allowsPrepopulate =>
defaultValue =>
description =>
content =>
cssClass => gf_right_half
errorMessage =>

So maybe something like:

if(is_array($form['fields'])){
        foreach($form['fields'] as $key=>$fieldinfo){
            foreach($fieldinfo as $key2=>$fielddata){
                if($key2=='type' && $fielddata=='email'){
                    $gf_field_id_email = $fieldinfo['id'];
                }
            }
        }
    }

and then you can access the entry data (email address) with this:
$entry[$gf_field_id_email]

Hope this helps!
