Anyway I used copied the Symfony code for objects_for_select and made
my own helper out of it. Its like this...
/**
* Accepts a container of objects, the method name to use for the
value,
* and the method name to use for the display.
* It returns a string of option tags.
*
* Default text to be displayed in the drop-down list can be passed.
* $defaultValue: value of default option
* $defaultText: display text of default option
*
* NOTE: Only the option tags are returned, you have to wrap this call
in a regular HTML select tag.
*/
function custom_objects_for_select($options, $value_method,
$text_method = null, $selected = null, $defaultValue = null,
$defaultText = null, $html_options = array())
{
$select_options = array();
// Added the following if condition
if($defaultValue != null && $defaultText != null)
{
$select_options[$defaultValue] = $defaultText;
}
foreach ($options as $option)
{
// text method exists?
$method_exists = ($text_method == '__toString') ? method_exists
($option, $text_method) : is_callable(array($option, $text_method));
if ($text_method && !$method_exists)
{
throw new sfViewException(sprintf('Method "%s" doesn\'t exist
for object of class "%s".', $text_method, _get_class_decorated
($option)));
}
// value method exists?
$method_exists = ($value_method == '__toString') ? method_exists
($option, $value_method) : is_callable(array($option, $value_method));
if (!$method_exists)
{
throw new sfViewException(sprintf('Method "%s" doesn\'t exist
for object of class "%s".', $value_method, _get_class_decorated
($option)));
}
$value = $option->$value_method();
$key = ($text_method != null) ? $option->$text_method() : $value;
$select_options[$value] = $key;
}
return options_for_select($select_options, $selected,
$html_options);
}
Thanks and Regards
