Messages

Messages are used to display status messages to the user, usually after a form is submitted.

Message Types

There are 5 types of messages

• Error

  

• Warning

  

• Success

  

• Info

  

• Purple Info

  

Each type is internally stored using an array, which means that each message can contain more than one line.

PHP Usage

Using Messages is very simple, and similar to how the global $wgOut variable is used with mediawiki. Messages uses a global variable $wgMessage, and messages can be added by using the following 5 methods:

global $wgMessage;

$wgMessage->addError("This is an error message");
$wgMessage->addWarning("This is a warning message");
$wgMessage->addSuccess("This is a success message");
$wgMessage->addInfo("This is an info message");
$wgMessage->addPurpleInfo("This is a purple info message");

Messages will always be display in the same order, regardless of when each method was called.

Messages can also be cleared by calling the following methods:

global $wgMessage;

$wgMessage->clearError();
$wgMessage->clearWarning();
$wgMessage->clearSuccess();
$wgMessage->clearInfo();
$wgMessage->clearPurpleInfo();

Javascript Usage

Messages can also be added using the javascript interface.

addError("This is an error message");
addWarning("This is a warning message");
addSuccess("This is a success message");
addInfo("This is an info message");
addPurpleInfo("This is a purple info message");

clearError();
clearWarning();
clearSuccess();
clearInfo();
clearPurpleInfo();
clearAllMessages();
