James Fuller has a new post to his blog today showing how to use flash messaging in the Lithium PHP framework.

In my case, I needed to display to the user a "flash message" after redirecting them to another page. CakePHP has this as part of the framework by default but Lithium will ask you to do a bit more work. Luckily, Lithium framework lead developer Nate Abele has created a handy extension to the Lithium session helper will will give us exactly what we need.

For those not familiar with what a "flash message" is, he defines it as a message available to the next page load with relevant information about the previous page. He includes the instructions on how to get the extension for this working in Lithium - downloading, configuring and adding the output variable for the flash messaging to your layout. He also includes an example of how to set the message so it'll be saved into the current session.
