Update Lead Meta

Hi
I am looking at ways of updating saved leads after the initial lead has been saved. I have been digging around forms_model.php and came up with the following code:

@include_once(WP_PLUGIN_DIR . "/gravityforms/gravityforms.php");
@include_once(WP_PLUGIN_DIR . "/gravityforms/forms_model.php");
$rg = new RGFormsModel();

$lead_id = 12;

$rg->update_lead_property($lead_id, 'custom', 200);

If I am trying to adjust a field within the rg_lead table (starred, ip, etc) then it would appear to work. However I cannot get it to update any value in the rg_lead_detail table - the custom field data for my form.

Is there a function or class available for interacting with the rg_lead_detail table. Something like:

$rg->update_lead_property_meta($lead_id, 'custom', 200);

Thanks

Hi Alex
Thanks for getting back. I have written the following code and it works well. My form redirects the user to a URL with a unique GET variable. This unique ID is used to retrieve the form information and then update the download counter. Only a certain number of downloads are permitted. Hopefully the code will be of use to others:

global $wpdb;

// get gravity forms
$rg = new RGFormsModel();

// search for this UID on form 2
$download = $rg->get_leads(2, 0, 'DESC', $_GET['uid'], 0, 1000);

// invalid UID
if (!$download) { wp_die(__('Invalid download link.','oo').' <a href="'.get_bloginfo('url').'">'.__('Get me out of here »','oo').'</a>'); }

// counter
$counter = $download[0][5];
if ($counter >= 2) { wp_die(__('File download limit exceeded.','oo').' <a href="'.get_bloginfo('url').'">'.__('Get me out of here »','oo').'</a>'); }

// update the counter (form 2, field 5)
$lead_detail_table = $rg->get_lead_details_table_name();
$count = $counter + 1;
$save = $wpdb->update($lead_detail_table, array("value" => $count), array("lead_id" => $download[0]["id"], "form_id" => 2, "field_number" => 5));

It would be useful for a having a few template functions for working with form data. Simple update, edit, retrieve, delete functions. While this goes beyond just data collection and the core of Gravity Forms it would massively increase the flexibility of the plugin.

Thank again

+1 for a GFFormsModel::save_input() like function for updating lead details without form input.
