Checkboxes pre_render and populated dynamic

Hi,

I have not problem creating a dynamic checkboxes with this code.

add_filter("gform_pre_render", "populate_dropdown_users");

function populate_dropdown_users($form)
{
	// recollim usuaris registrats
	global $wpdb;
	$allAuthorIds = $wpdb->get_col( "SELECT ID FROM {$wpdb->users}" );
	$authorsInfo = array();
	$items = array();
	foreach( $allAuthorIds as $authorId ) {
  		$authorsInfo[$authorId] = get_userdata($authorId);
  		if($authorsInfo[$authorId]->user_level==0)
  		{
  			$items[] = array("value" => $authorId, "text" => "<img src=\"http://www.gravatar.com/avatar/".md5($authorsInfo[$authorId]->user_email)."?s=30\" class=\"img_avatar\">".$authorsInfo[$authorId]->display_name);
  		}
	}

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

		// buscarem els que tenen cssClass == custom_field_usuaris
	 	 if(strpos($field['cssClass'],'custom_field_usuaris')===false)
            continue;

          $field["choices"] = $items;

	}

	 return $form; // retornem el formulari

}

But when I tried to create a form with this checkboxes and populated dynamically a content, only first element is selected.

Example.

$field_values = array();
$field_values['projProfe'] = "2,3";
gravity_form(2, false, false, $display_inactive=false, $field_values, false);

Only checkboxes with 2 value is checked not, checbox with value 3 is checked. If I do this with a checkbox with no pre_render content work correctly.

Any idea?

thanks.

My problem not is in email notification, entry list, entry detail, because in this case not use.

I think that the problem is that an incompatible problem with populated dynamically and a checkbox that is filled dynamically.

David.

Alex, this work, but is not a solutio for me. I need to select checkbox from a dynamic value. I can know $field_values inside gform_pre_render hook?

$field_values = array();
$field_values['projProfe'] = "2,3";
gravity_form(2, false, false, $display_inactive=false, $field_values, false);
