Using the modules "Note" parameter

The Note field of a Joomla module is intended to display some comment for admin use in the back end, but it's such a handy parameter that it would be a real shame to just waste it on the back end.

One handy use I have for the note field is to use it to display some information on the front end, essentially turning it into a custom field. I quite commonly use it to create a button, using the note field to store the URL link, although it can for virtually any purpose.

The following is an example of how it can be incorporated into the module template file:

<?php

$menuitemid = JRequest::getInt('Itemid');
$db =& JFactory::getDBO();
$query = "SELECT note FROM #__modules WHERE id = '".$module->id."' ";
$db->setQuery($query);
$note = $db->loadResult();

echo $note;
?>

Displaying a module title

Occasionaly it's neccessary to display a module title in a different position within your module overide. I've found that I most commonly need to do this with joomla's built in Custom HTML module. The solution is rather easy:

<?php if ($module->showtitle) {
echo '<h3>' .$module->title .'</h3>';
} ?>

Module positions anywhere

Using this code, you can place a module position inside any php file in joomla:

<?php
$myblurb_modules = &JModuleHelper::getModules( 'my-new-position' );
foreach ($myblurb_modules as $myblurb) {
$_options = array( 'style' => 'xhtml' );
echo JModuleHelper::renderModule( $myblurb, $_options );
}
?>

Using PHP include to navigate up a folder

On occassion I've needed to include a file that was outside the current the directory. To do so use the following:

<?php
include(dirname(__FILE__)."/../../blocks/mod_events.php");
?>

The include(dirname(_FILE_) returns the current path.

The following is a conditional to do something if the post is contained within wither of these three categories:

<?php if (in_category( array( gallery,this,another ) )) {
echo 'BINGO!!';
} ?>
Published in Blog

Before you proceed, please note that the code below will remove featured images from all posts on your WordPress site by simply just pasting. Also note that this code will not delete any of your uploaded images, they will still be available in Media Library and you can reuse them anytime.

All you need to do is copy and paste this code in your theme’s functions.php file.

global $wpdb;
$wpdb->query( "
    DELETE FROM $wpdb->postmeta 
    WHERE meta_key = '_thumbnail_id'
" );

As soon as you save your functions.php file this script will run a database query and remove featured images from all posts.

Important: Please remove this code immediately after saving your functions.php file. You will not be able to set featured images in WordPress as this code will keep removing featured images from posts.

Adding a favicon to the Joomla T3 framework

One of the annoying bugs of the T3 framework is that it over writes the favicon everytime the framework is updates. To fix this, upload the favicon outside of your template directory. In decided to upload it directly into th root template folder.

Firstly, I put the variable $path at the top of the head. This is only neccassary if you want to dynamically insert the URL - But it's handy to do so, and I suggest you do, otherwise you would have to type the full absolute path.

<?php
$app = JFactory::getApplication();
$path = JURI::base(true).'/templates/'.$app->getTemplate().'/';
?>

 

Put the following into the head block, but make sure it comes after the call to load the T3 head:

<link rel="shortcut icon" href="<?php echo $path; ?>../favicon.ico" />

 

My head block looks something like this:

<?php
// T3 BASE HEAD
$this->addHead();
?>

<link rel="shortcut icon" href="<?php echo $path; ?>../favicon.ico" />
