I think this is something that is going to be considered in version 1 or
beyond.
However, if you can't wait heres an example of how you can easily achieve
this.
== Extending core classes ==
* !BaseView - Get the Flash Class and automatically sets to Attribute
for template
== Flash Class ==
* Simple parameter holder, gets any flash messages from session in the
constructor.
== Usage ==
=== Before the View ===
* Either pass in the $rd and in the view write to a message - could be
automated
* Add to the session i.e.:
{{{
$storage->write('agavi.org.flash', array($message, $style));
}}}
=== View ===
{{{
$this->flash->write($message, $style);
}}}
=== Master Template ===
{{{
<?php if ($t['flash']->hasFlash()): ?>
<?php $flash = $t['flash']->read();?>
<div class='flash <?php echo $flash['1']; ?>'><?php echo $flash['0'];
?></div>
<?php endif; ?>
}}}
== Caveats ==
* Flash messages are destroyed as soon as the flash->read(); method is
called.
* Flash messages will live in the session until flash->read() is called.
* Only allows a single flash message.
* Not integrated so mulitple interfaces i.e. add via the session before
the view and via $this->flash in the view.
Comment (by ross):
Updated Class - made standalone - so session only based.
Added hasFlashType - thanks André.
