To open a modal box in Joomla using Javascript, first make sure the modal behavior is loaded:

JHTML::_('behavior.modal');

Then, open an external resource with an iframe handler:

SqueezeBox.setContent( 'iframe', 'http://google.com' );

I always forget the command to reconfigure Plesk after adding a vhost.conf file.

The command to reconfigure Plesk for one site is:

/usr/local/psa/admin/sbin/websrvmng -u --vhost-name=domain.com

or the command I use reconfigures all sites:

/usr/local/psa/admin/bin/websrvmng -a

The Joomla frameworks offers an easy solution to insert a date field with a pop-up calender select box, to easily select a date. The pop-up is Mootools operated.

Virtuemart has a multiple currency feature where users can select from a pre-defined set of currencies for checkout.

This is very useful, but has a major bug when checking out with Paypal. The final order logged in Virtuemart is correct, and has the correct currency. However, when the user is redirected to Paypal, the transaction will be done in the default currency of the Virtuemart shop.

This problem has existed since 2009, and in 2011 I would have expected it to be resolved already.

I would class this as a major problem as it results in incorrect transactions.

You can rename projects in Netbeans however, if you keep the NetBeans metadata files separate from your source files, you can not change the source directory from the Netbeans interface.

Luckily the NetBeans project files are simple text files, so we can easily change it there. Close NetBeans (so that you don’t accidentally overwrite the new project file). Find the project directory and open the directory called nbproject. Then open the file project.properties.

Change this:

src.dir=<old path>

To:

src.dir=<new path>

In Joomla 1.7 (and I assume Joomla 1.6) you can very easily execute content plugins on a string.

$text = JHTML::_('content.prepare', $text );

This is much simpler than the previous method in Joomla 1.5:

$Item = JTable::getInstance('content');
$dispatcher = JDispatcher::getInstance();
$params = new JParameter('');
JPluginHelper::importPlugin('content');
$Item->parameters = new JParameter('');
$Item->id = "";
$Item->state = "";
$Item->catid = "";
$Item->sectionid "";
$Item->title "";
$Item->text = "Your text with {content plugin code}";

// Apply content plugins to custom text
$results = $dispatcher->trigger('onPrepareContent', array (&$Item, &$params, 0));

I have many email accounts setup in Thunderbird, and I star message which I want to give more attention to later. Unfortunately, thunderbird does have an option to view all "starred" messages.

Google have taken the decision to drop h.264 and adopt the WebM (VP8) & Theora video codecs for Chrome’s HTML5 <video> support. The Chronium Blog post on January 11, 2011 sets out their current position on the subject and further complicates the long running HTML5 video codec debate.

Flash does not load browser cookies when sending HTTP requests (except in Internet Explorer where persistent cookies are loaded). Any requests from Flash will be processed as a new user agent.

This raised a problem for me when trying to perform an AJAX request from a Flash object which required session data from Joomla. The session data of the user performing the request was not passed.

Obviously, I'm not the first to experience this issue and it is widely discussed elsewhere, but not so much when it comes to Joomla.

The "send to friend" feature in Joomla allows you to recommend pages to your friends by emailing them directly from Joomla. One common cause of the E-mail could not be sent error message is the anti-spam measure enforced by Joomla. If you try to send an email within 20 seconds of opening the page, Joomla will produce this error message.
