Further to this I have been examining the Code to try and get at a property
to see if it already exists:
I see this in: abstract class
Zend_View_Helper_Placeholder_Container_Standalone
/**
* Overloading: retrieve property
*
* @param string $key
* @return mixed
*/
public function __get($key)
{
$container = $this->getContainer();
if (isset($container[$key])) {
return $container[$key];
}
return null;
}
However as the Container is a sequential object it would be lucky to get the
property I want based on the key wouldn't it as I need to pass in an int
value
Zend_View_Helper_Placeholder_Container Object ( [0] => stdClass Object (
[type] => name [name] => title [content] => Content. [modifiers] => Array (
) ) [2] => stdClass Object ( [type] => name [name] => keywords [content] =>
keywords [modifiers] => Array ( ) ) [3] => stdClass Object ( [type] => name
[name] => description [content] => description [modifiers] => Array ( ) ) )
What i want is the property based on the name.
Sorry if I am missing a trick here but just need to see if Description is
already set if it is then do not set again.
