Introduction BetaUserPoints - API integration in a Third party component (advanced)

This documentation is dedicated to developers and anyone with a sufficient knowledge of the PHP language and Joomla 4 component development. Licence: BetaUserPoints is released under license GNU/GPL License. Author: Bernard Gilly – Adrien Roussel - Martin Brampton. This project started as AlphaUserPoints back in 2008.

A plugin creation (new rule creation for a 3rd party component) is done in 2 steps

Just insert the following API in the component code where needed. The best way is to make it follow a user action that could give the users some points or take some. For example : in a comment system component or in a forum, just add the API after the comment or topic INSERT query in the database.

    $api_BUP = JPATH_SITE.'/components/com_betauserpoints/helper.php';
    if ( file_exists($api_BUP))
    {
        require_once $api_BUP; BetaUserPointsHelper::newpoints( 'function_name' );
    }

function_name is the name of the rule that will be used to attribute points to the current user (if logged in). For each BetaUserPoints integrated rule (system rules), names syntax is as follows:

example: sysplgbup_newregistered for new users points attribution

It is convenient to keep the same name syntax for third party components plugin as follows:

plgbup_functionname

Example: plgbup_newcomment or plgbup_newtopic for a comment system or forum API integration. To name a rule that would give points when adding a new topic in Kunena: plgbup_kunena_topic_create.

Keep in mind that this method only gives points to the current user logged in. This is the Basic API.

To give points to anothe user than the one connected, only the user id is required. To get his BetaUserPoints (BUPID) Identity, we just need to use the getAnyUserReferreID(). This method is the one used to give points to an article author when the article is being read by someone on the site.

    $api_BUP = JPATH_SITE.'/components/com_betauserpoints/helper.php'; 
    if ( file_exists($api_BUP))
    { 
        require_once $api_BUP;
        $bupid = BetaUserPointsHelper::getAnyUserReferreID( $userID );
        if ( $bupid ) BetaUserPointsHelper::newpoints( 'function_name', $bupid ); 
    }

To avoid a user getting points many times for something already done, we can add a reference key. When calling the BetaUserPointsHelper::newpoints function, a precheck is done on this reference key. This method is used in the rule where a user reading an article would give points to the author.

    $api_BUP = JPATH_SITE.'/components/com_betauserpoints/helper.php';
    if ( file_exists($api_BUP))
    {
        require_once $api_BUP;  
        $keyreference = BetaUserPointsHelper::buildKeyreference('function_name', 'item id' );  
        BetaUserPointsHelper::newpoints( 'function_name', '', $keyreference);  
    }

To add information datas to be displayed in the action details, just add a new parameter as follows:

    $api_BUP = JPATH_SITE.'/components/com_betauserpoints/helper.php';
    if ( file_exists($api_BUP)) 
    {
        require_once $api_BUP;  
        $keyreference = BetaUserPointsHelper::buildKeyreference('function_name', 'item id' );  
        BetaUserPointsHelper::newpoints( function_name','', $keyreference,'information_datas');  
    }

A component might also need to add or to take points for different amounts. For example, when buying goods with points. Products have different prices, a fixed amount in the rule would'nt make it. The API $randompoints parameter comes instead of the amount of points set in the rule. It can be negative in case of purchases or penalities.

    $api_BUP = JPATH_SITE.'/components/com_betauserpoints/helper.php';
    if ( file_exists($api_BUP))
    {
        require_once $api_BUP;  
        $keyreference = BetaUserPointsHelper::buildKeyreference('function_name', 'item id' );  
        BetaUserPointsHelper::newpoints( function_name','', $keyreference,'',-1450);  
    }

In a more advanced code, if the component routine needs to know if the operation has been successful or not, (enough amount of points for a purchase in a user account), we can add a 'feedback' parameter. It has a Boolean type value. Code example:

    $api_BUP = JPATH_SITE.'/components/com_betauserpoints/helper.php';
    if ( file_exists($api_BUP))
    {
        require_once $api_BUP;
        $keyreference=BetaUserPointsHelper::buildKeyreference('plgbup_purchasewithvirtuemart', $transactionID );
        if (BetaUserPointsHelper::newpoints( 'plgbup_purchasewithvirtuemart', '', $keyreference, 'Product reference: AM-5245', -1290, true))
        {
            [... code continued ...]
        }
    }

In a customized code component, you can force and remove the constraint on a rule to the user level by adding the parameter _force = 1_. The existing rule will be available now for _guest, registered_ and _special_.

you can display a specific message on frontend by adding the parameter frontmessage=”You custom message”. API full implementation

    BetaUserPointsHelper::newpoints(
        string$pluginfunction,
        [string$BUPIDotheruser = ''],
        [string$keyreference = ''],
        [string$data = ''],
        [integer$randompoints = 0],
        [boolean$feedback = false],
        [integer$force=0],
        [string$frontmessage='']
    );

Note: If the operation is a points substraction, the account has to have at least the same amount of points. If not, a notice warns the user that he doe'snt have enough points to complete the action (by default). You can set up general parameter in the configuration of BetaUserPoints, in backend administrator to allows your users to have a negative account.

Then developers have to create an xml file to make easier the installation process in the BetaUserPoints component. This xml file has to be utf-8 encoded (required). All developers of third party extensions for Joomla! can add directly at the root of their frontend component a unique xml file containing all the rules for a single component. Deveoper has to respect the ordering and tags: structure example: [betauserpoints_rule.xml](images/stories/documentation/betauserpoints/betauserpoints_rule.xml) Tag “component” is the name of the third component like “com_kunena” or other. As it is the same component, it is worth repeating for each rule in the tag “rule”. Administrator of the website which install a third component with this xml file can autodetect directly from the button “auto-detect plugins” in control panel of BetaUserPoints. This xml file has to be utf-8 encoded (required) but not be zipped! Just put this file at the root of frontend component folder or plugin or module and include this file in your installer extension. This file must be named exactly as follows: betauserpoints_rule.xml

ar -> articles
cd -> coupons
co -> community
fo -> forums/comments
li -> links
mu -> music
ot -> other
ph -> photo
po -> polls
pu -> purchase
re -> recommend/send to a friend
sh -> shopping
su -> private
sy -> system rules
us -> users
vi -> video

NOTE : Optionally, you can avoid this step manually by filling all the fields in the creation of a new rule directly in the rule manager (button 'New' in toolbar).

- auto-detect xml file at the root of frontend component: Click on the button “Auto-detect plugins” in the control panel of BetaUserPoints after installation of third component, plugin or module. Check regularly or periodically by clicking on this button.

You can use easily the profil informations of a user directly in a third component. ⇒ Before using a function, you must include the API at least once in your page like this:

$api_BUP = JPATH_SITE.'/components/com_betauserpoints/helper.php'; if ( file_exists($api_BUP)) { require_once $api_BUP; }

To get the entire profil information, just use the function getUserInfo(); Just use the referreid of BetaUserPoints user or the joomla ID of the user (Id of Joomla users table).

Use the first method with the referreid to get user Information profile like this :

BetaUserPointsHelper::getUserInfo($referrerid );

If you do not have the referreid, you can use the ID of user in second parameter like this :

$user = JFactory::getUser(); $userid = $user->id ; $profil = BetaUserPointsHelper::getUserInfo ( '', $user->id );

Then you can get the following user informations:

$profil->name
$profil->username
$profil->registerDate
$profil->lastvisitDate
$profil->email
$profil->referreid
$profil->points
$profil->max_points
$profil->last_update
$profil->referraluser
$profil->referrees
$profil->blocked
$profil->birthdate
$profil->avatar
$profil->levelrank
$profil->leveldate
$profil->gender
$profil->aboutme
$profil->website
$profil->phonehome
$profil->phonemobile
$profil->address
$profil->zipcode
$profil->city
$profil->country
$profil->education
$profil->graduationyear
$profil->job
$profil->facebook
$profil->twitter
$profil->icq
$profil->aim
$profil->yim
$profil->msn
$profil->skype
$profil->gtalk
$profil->xfire
$profil->profileviews

Display the image of avatar from BetaUserPoints.

$avatar = BetaUserPointsHelper:: getAupAvatar( $userid, [$linktoprofil=0], [ $width=48], [$height=48], [$class=''], [$otherprofileurl=''] ) echo $avatar ;

if $linktoprofil set to 1, display avatar with the link to the BUP profil of this user.

Get the url to show the profil of user.

$linktoBUPprofil = BetaUserPointsHelper::getAupLinkToProfil($userid);

Get the url to show the list of users with points etc…

$linktoBUPusersList = BetaUserPointsHelper:: getAupUsersURL();

Get the path avatar path of a specific user

$avatarPath = BetaUserPointsHelper:: getAvatarPath( $userid );

Get the live url avatar path of a specific user

$avatarLivePath = BetaUserPointsHelper:: getAvatarLivePath( $userid );

$medalslistuser = getUserMedals($referrerid);

or

$medalslistuser = getUserMedals('', $userid);

return $medallistuser->id
return $medallistuser->rank (name of medal)
return $medallistuser->description (reason for awarded)
return $medallistuser->icon (name file icon)
return $medallistuser->image (name file image) Complete example to display large image of medals:

    $user = JFactory::getUser();
    $userid = $user->id;
    if(!defined("_BUP_MEDALS_PATH"))
    {
        define('_BUP_MEDALS_PATH', JURI::root() . 'components/com_betauserpoints/assets/images/awards/large/');
    }
    if(!defined("_BUP_MEDALS_LIVE_PATH"))
    {
        define('_BUP_ MEDALS _LIVE_PATH', JURI::base(true) . '/components/com_betauserpoints/assets/images/awards /large/');
    }
    $medalslistuser = BetaUserPointsHelper::getUserMedals( '', $userid );
    for each ( $medalslistuser as $medallistuser )
    {
        echo '<img src="'. _BUP_MEDALS_LIVE_PATH'.$medallistuser->image . '" alt="" />';
    }

$referreid = BetaUserPointsHelper::getAnyUserReferreID( $userID );

Use the first method with the referreid to get the total of points

$totalPoints = BetaUserPointsHelper::getCurrentTotalPoints( $referrerid );

If you have not the referreid, you can use the ID of user (joomla) in second parameter like this :

$user = JFactory::getUser(); $userid = $user->id ; $totalPoints = BetaUserPointsHelper::getCurrentTotalPoints( '', $userid );

$listActivities = BetaUserPointsHelper::getListActivity($type='all', $userid='all', $numrows=0); 

$params $type = all | positive | negative
$params $userid = all or unique userID
$params $limit = int (0 by default)
example-1 -> -------------------------------------------------------------------------
example-1 -> $listActivities = BetaUserPointsHelper::getListActivity('all', 'all');
example-1 SAME AS -> $listActivities = BetaUserPointsHelper::getListActivity();
example-1 -> show all activities with pagination, positive and negative points of activity for all users
-----------------------------------------------------------------------------------
example-2 -> -------------------------------------------------------------------------
example-2 -> $user = JFactory::getUser();
example-2 -> $userID = $user->id;
example-2 -> $listActivities = BetaUserPointsHelper::getListActivity('positive',$userID,20);
example-2 -> show only positive points of activity for the current user logged in and show only 20 rows of recent activities

Returns an array or $rows

List of available fields :

insert_date
referreid
points (of this activity)
datareference
rule_name
plugin_function
category

$nextrankinfo = BetaUserPointsHelper::getNextUserRank($referrerid='', $userid='0', currentrank);

return $nextrankinfo->id
return $nextrankinfo->rank (name of rank)
return $nextrankinfo->description (description of rank)
return $nextrankinfo->levelpoints (level points to reach this rank)
return $nextrankinfo->typerank (return 0)
return $nextrankinfo->icon (name file icon)
return $nextrankinfo->image (name file image)

$num_bup_version = BetaUserPointsHelper::getBupVersion();

Returns the current version of BetaUserPoints like → 4.0.0
