Joomla’s Breezing Form data variables:

// fallback if no template exists

if ($this->record_id != '')
$body .= BFText::_('PROCESS_RECORDSAVEDID')." ".$this->record_id.nl().nl();
$body .=
BFText::_('PROCESS_FORMID').": ".$this->form.nl().
BFText::_('PROCESS_FORMTITLE').": ".$this->formrow->title.nl().
BFText::_('PROCESS_FORMNAME').": ".$this->formrow->name.nl().nl().
BFText::_('PROCESS_SUBMITTEDAT').": ".$this->submitted.nl().
BFText::_('PROCESS_SUBMITTERIP').": ".$this->ip.nl().
BFText::_('PROCESS_PROVIDER').": ".$this->provider.nl().
BFText::_('PROCESS_BROWSER').": ".$this->browser.nl().
BFText::_('PROCESS_OPSYS').": ".$this->opsys.nl().nl();
if (count($this->maildata)) foreach ($this->maildata as $data)
$body .= $data[_FF_DATA_TITLE].": ".$data[_FF_DATA_VALUE].nl();
}

$attachment = NULL;
if ($this->formrow->emailxml>0) {
$attachment = $this->expxml();
if ($this->status != _FF_STATUS_OK) return;
} // if

for($i = 0; $i < $recipientsSize;$i++){
$this->sendMail($from, $fromname, $recipients[$i], $subject, $body, $attachment, $isHtml);
}
echo "test";
} // sendEmailNotification

Using following code we can get joomla’s language and use it in our extensions code.

$lg = &JFactory::getLanguage();
$language = $lg->getBackwardLang();

$language will give us the current language selected.

$uri is global variable which holds current SEF url in Joomla 1.0

global $uri;
$thisurl = 'http://'.$_SERVER['SERVER_NAME'].DS.'component'.DS.$uri[1];

Some useful Ubuntu command lines I use often:

Restart Appache

/etc/init.d/apache2 restart

Restart MySQL

/etc/init.d/mysql restart

Find Ubuntu Server Specs

cat /etc/lsb-release

Update the directory permissions

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

Collect Statictics data:

/usr/local/psa/admin/sbin/statistics >/dev/null 2>&1

Following is a template that can be used to develop plugins to inert code into Joomla head section.

Use following code to turn off/remove Mootools in Joomla template on frontend.

$user =& JFactory::getUser();
if($user->get('guest') == 1) {
	$search = array('mootools', 'caption.js');
	// remove the js files
	foreach($this->_scripts as $key => $script) {
		foreach($search as $findme) {
			if(stristr($key, $findme) !== false) {
				unset($this->_scripts[$key]);
			}
		}
	}
}

JavaScript:
Use inline JavaScript to send user back to previous page.

<input type="button" value="Go Back" onclick="history.back(-1)" />

Can also send user two steps back as well.

<input type="button" value="Go Back" onclick="history.back(-2)" />

PHP:
PHP code to send user back.

<?php
  $url = htmlspecialchars($_SERVER['HTTP_REFERER']);
  echo "<a href='$url'>back</a>";
?>

Input elements can be targeted by assigning tags to the same input types. It is possible that we want to style input elements as text input fields, text areas and select boxes to have different widths while button input elements to have a different style.

<input type="text" class="text" />
<input type="checkbox" class="checkbox" />
<input type="radio" class="radio" />
<input type="button" class="button" />

Can also use multiple classes:

<input type="password" class="password text" />

Now using following in css we can target each type separately.

input[type="button"] { border:2px solid #ccc; padding:3px}
