Check if message queue is empty

[Allon Moritz]

hello

how can I check if the message queue is empty? Google didn't help much on this topic :-)

[Kannan Naidu]

I use this .. it displays the error message when the message is not empty

<?php if(count(JFactory::getApplication()->getMessageQueue())):?>
  bla..bla..bla
<?php endif; ?>

But this empties the queue? After that the messages will not be displayed in the messages part of the template anymore...

[laoneo]

Does somebody have any hint how to detect if the message queue is empty without getting all the messages out of it?

Thanks.

What if you would duplicate the JApplication::getMessageQueue method, just without emptying the queue?

https://github.com/joomla/joomla-cms/blob/master/libraries/legacy/application/application.php#L424

$session = JFactory::getSession();

$sessionQueue = $session->get('application.queue');

$isEmpty = !count($sessionQueue));

It's not forward-compatible/ safe against the session key change, but it's probably the only way now.

IMHO better way would be adding new parameter to the method:

/**

 * @param   boolean  $flush  Flushes the queue. Defaults to true for backward compatibility.

 */

getMessageQueue($flush = true)

I think duplicating it is not an option because the messages are cached in an array after the first access. But I like the idea of adding an extra parameter. Do you think a pull request would be accepted?

It's really hard to tell, it's been a while since my PR has been merged. But this issue omes back once a time and IMHO optional parameter is way out

[Michael Babker]

To retrieve the message queue without clearing it, your best option most likely is to basically hack the API via Reflection.  The queue is stored in a protected access internal array within JApplication and only set to the session when requests are made.

 

$reflection = new ReflectionClass(JFactory::getApplication());
$queueProp = $reflection->getProperty('_messageQueue');
$queueProp->setAccessible(true);
$messageQueue = $queueProp->getValue(JFactory::getApplication());
