Use this package to display info/warning/error messages to the user on a web page. Using the SessionMessageService class, you register messages to be displayed. Using the MessageWidget class, you display the error messages in your templates.
This service allows to implement user oriented messaging. It relies on a simple function that will add a message with a given level, and an HTML block that will render user's messages when the page is loaded.
When the package is installed, a block is added to the template's content. When rendered, this block will dump the messages that were stored into the session.
Add a message :
$messageService->setMessage("User <b>foo bar</b> has been successfully cerated", UserMessageInterface::SUCCESS);
UserMessageInterface defines 4 types of message :
By default, the message will be displayed in the header block. But you are free to insert this block anywhere.
