Just another WordPress weblog

Using following code component parameters can be retrieved in plugins and modules.

If component has parameters in its Global Configurations use following:

$params = &JComponentHelper::getParams( 'component_name' );
$parammeter = $usersConfig->get( 'parameter_name' );

Use following if component have configurations inside component page:

$params = $mainframe->getParams('component_name');
parammeter  = $params->get('parameter_name');

Change the umask in ‘/etc/proftpd.conf’ from ’022′ to ’002′.

Then, update the directory permissions by running the following at the command line:

cd /var/www/vhosts/[domain.com]
chown -R [username]:psacln httpdocs
chmod -R g+w httpdocs
find httpdocs -type d -exec chmod g+s {} \;

Add the ‘apache’ user to the ‘psacln’ group by editing ‘/etc/group’.

psacln:x:2524:apache

You can use a plugins functions from another plugin or component using following codes.
These are for Joomla 1.5

$Plugin =& JPluginHelper::getPlugin('system', 'saleslogix');
$dispatcher =& JDispatcher::getInstance();
$plg = array("type"=>"system","name"=>"saleslogix","params"=>$Plugin->params);
$saleslogixPlg = new plgSystemSaleslogix( $dispatcher, $plg );
//$resultHere = $saleslogixPlg->myFunction();

OR

JPluginHelper::importPlugin('system');
$app = &JFactory::getApplication();
$app->triggerEvent('onAfterInitialise');

You can enter your website urls with a www or with no www. Which is better I leave for you to google and find out yourself. Using both is not a good idea as search engines and Facebook will not treat them same and will cause problems.

Solution is to force one of them to be used and not both. So if a users enters http://www.youtsite.com gets to http://yoursite.com and vice versa.

Solutions 1: Using Mod Rewrite
Following code should be placed in htaccess file in root directory of your website.

If your want to http://www.yoursite.com use following code:

<IfModule mod_rewrite.c>
   Options +FollowSymLinks
   Options +Indexes
   RewriteEngine On
   RewriteBase /
   RewriteCond %{HTTP_HOST} ^domain\.com$
   RewriteRule ^(.*)$ http://www.domain.com/$1 [R=301,L]
</IfModule>

If your want to http://yoursite.com use following code:

<IfModule mod_rewrite.c>
   Options +FollowSymLinks
   Options +Indexes
   RewriteEngine On
   RewriteBase /
   RewriteCond %{HTTP_HOST} ^www\.domain\.com$
   RewriteRule ^(.*)$ http://domain.com/$1 [R=301,L]
</IfModule>

Joomla website users:
You can use following free plugin from JED

<?php
function CreateNewUser($name, $username, $email, $password, $registerDate = NULL, $usertype = 'Registered', $block = '0', $sendEmail = '1', $gid = '18') {
        global $db;

        $db = & JFactory::getDBO();
        jimport('joomla.user.helper');

        //Make the joomla password hash
        $salt = JUserHelper::genRandomPassword(32);
        $crypt = JUserHelper::getCryptedPassword($password, $salt);
        $joomlapassword = $crypt . ':' . $salt;

        //Table #__users
        //Informations about the user
        $user = new stdClass;
        $user->id = NULL;
        $user->name = $name;
        $user->username = $username;
        $user->email = $email;
        $user->password = $joomlapassword;
        $user->registerDate = registerDate;
        $user->usertype = $usertype;
        $user->block = $block;
        $user->sendEmail = $sendEmail;
        $user->gid = $gid;

        if (!$db->insertObject('#__users', $user, 'id')) {
            echo $db->stderr();
            return false;
        }

        //Table #__core_acl_aro
        //Discover what is the last value of value in #__core_acl_aro
        $query = "SELECT value FROM #__core_acl_aro ORDER BY id DESC LIMIT 1";
        $db->setQuery($query);
        $coreaclarolastvalue = $db->loadResult();

        $coreaclaro = new stdClass;
        $coreaclaro->id = NULL;
        $coreaclaro->section_value = 'users';
        $coreaclaro->value = $coreaclarolastvalue + 1;
        $coreaclaro->order_value = NULL;
        $coreaclaro->name = $name;
        $coreaclaro->hidden = NULL;

        if (!$db->insertObject('#__core_acl_aro', $coreaclaro, 'id')) {
            echo $db->stderr();
            return false;
        }

        //Table #__core_acl_groups_aro_map
        $coreaclmap = new stdClass;
        $coreaclmap->group_id = $gid;
        $coreaclmap->section_value = NULL;
        $coreaclmap->aro_id = $coreaclaro->id; // maybe just $user->id ?

        if (!$db->insertObject('#__core_acl_groups_aro_map', $coreaclmap)) {
            echo $db->stderr();
            return false;
        }

        $CreateNewUserInfo = array($user->id, $user->name, $user->username, $user->email);
        return $CreateNewUserInfo;
}

Implementation

//This exemple will take data from one post, for example
$username = JRequest::getVar('username');
$name = JRequest::getvar('name');
$email = JRequest::getVar('email');
$password = JRequest::getVar('password');

//This code will call your funcion, then register with your data
$NewUserInfo = CreateNewUser($name, $username, $email, $password, $registerDate);

Gives current menu:

$currentMenuName = JSite::getMenu()->getActive()->name ;

Current Menu ID:

$currentMenuId = JSite::getMenu()->getActive()->id ;

Gives menu status, published (1) and unpublished (0)

$currentMenuStatus = JSite::getMenu()->getActive()->published ;

Non SEO URL of current menu:

$currentMenuLink = JSite::getMenu()->getActive()->link ;

Current menus parent ID:

$currentMenuParent = JSite::getMenu()->getActive()->parent ;

Current Menu’s Access Level Value.(Public = 0, Registered = 1, Special= 2)

$currentMenuAccess = JSite::getMenu()->getActive()->access ;
