# Configuration

new GW_Populate_Entries( array(

    'target_form_id' => 449,        // the form that contains the field to be populated
    'source_form_id' => 414,        // the form from which entry data should be retrieved
    'value' => '{entry_id}',        // specifies the data that should be populated for the choice's 'value'; can be a field ID (i.e. 12) or a 'template' string with merge tag support (i.e. '{entry_id}')
    'label' => '{:1.3} {:1.6} ({entry_id})', // same as 'value' but used to populate the label of the choice
    'query_args' => array(          // specifies which entries should be pulled for display
        'status' => 'trash',
        'field_id' => '1.3',

I'm looking for something like this but for the List Field drop down. I can get it to work for user meta, but not for Gravity Entries:

add_filter( 'gform_column_input_42_1_3', 'business_column', 10, 5 );
function business_column( $input_info, $field, $column, $value, $form_id ) {

  $items = array();
// Get the custom field values stored in the array

// If editing this lookup where you would like to get your data from
// this example loads through all users of the website
$metas = get_users( array( 'role' => 'company' ) );

if (is_array($metas))
{
// in this example we just load the display_name for each user into our drop-down field
foreach($metas as $meta) $items[] = array("value" => $meta->display_name, "text" => $meta->display_name);
}

return array( 'type' => 'select', 'choices' => $items );

}

Any thoughts?

How do you change this to alphabetical order? I see :
'order_by' => '1.3
What's that mean? What do I need to change in the config?

Somebody has the solution to auto populate fields based on the selection from the drop down box?
@WesternWebDoc commented one year ago this question, and nobody reply it.
Thanks a lot!
