Home Handlers

What is a handler.

A handler is a server script, that returns data (usually in XML format) to the application upon request. For example, it can return user profile information or user authorization information.

All handlers can be edited in the application main settings file /flashcoms/updater/settings/main.xml, however, make sure you ’re not removing markers, like: {ROOT}, {NAME} and {UID}. These are system markers in which the application inserts the appropriate values.

Depending on the application and handler you may find several different markers. The most commonly used markers are:

ROOT root folder for all flashcoms applications (PROJECT_HTTP_ROOT/flashcoms/).
NAME user name.
UID user identifier (used  when site authorization is not session/cookies based)

{ROOT} marker value ends with “ / ”, so if you change the path of the handler file to, for example, /avatar.php located in the PROJECT_HTTP_ROOT folder, then the new address path should look like this: {ROOT}../avatar.php

Updater handler

Updater handler can be edited in the handlers sections of the main settings file (/flashcoms/updater/settings/main.xml):


Authorization handler allows you to integrate the Community Messenger with your web site users' database.


UID - optional parameter which receives user identifier that has been passed to the application. Used for non session/cookies based authorization.

If authorization is passed successfully:

<auth error="">


Node name Description
userName Required. User login name.
gender User's gender. Can take 'male', 'female' or 'couple' value.
level User's authorization level. Required when limitation plugin is installed.

If not authorized:

<auth error="AUTH_ERROR" />

 Example code below illustrates the handler logic:

//check if is set session variable

echo '< auth error="AUTH_ERROR" />';
//connect to users database

$db = mysql_connect(DB_HOST,DB_USER,DB_PASSWORD) or die(mysql_error());
mysql_select_db(DB_NAME,$db) or die(mysql_error());

//select information for current user from database

$sql = "SELECT * FROM users_table WHERE user_id=".$_SESSION["user_id"];
$result = mysql_query($sql,$db);
$users_row = mysql_fetch_array($result);

//return information about user in xml format to the updater

echo '< auth error="">';
echo '< userName>'.$users_row['user_name'].< /userName>';
echo '< /auth>';
//where $_SESSION["user_id"] is a session variable which is initialized when a user logged in to your site
