That is going to require some customization. You may want post something on our Job Board or look for some help here. I’ll leave it open in case anyone has an idea to share. Thank you.
We (Gravity Wiz) have an early-access plugin available called GF Populate Anything that will handle populating a Drop Down field with a list of users and also populating the Name field with the selected users’s name.
If you’re a Gravity Perks customer, drop us a line via the support form and we’ll be happy to send you a copy of the plugin.
Soo… this is older, but if you are still looking, this is how I solved it for myself:
<?php
add_filter( 'gform_column_input_{form_id}_{field_id}_{column_number}', 'column_name', 10, 5 );
function column_name( $input_info, $field, $column, $value, $form_id ) {
//Form ID that you are getting the entries from
$form_id = 45;
$entries = GFAPI::get_entries( $form_id );
$items = array();
if (is_array($entries))
{
foreach ($entries as &$entry){
//Field ID of the entries you want to pre populate
$items[] = array("value" => $entry['2'], "text" => $entry['2']);
}
return array( 'type' => 'select', 'choices' => $items );
}
die();
}
