joomla how to remove js

By default joomla have some default js. Some time we need to remove the default js. last week my friend asked me to remove mootools.js in his project i searched via the Best Friend (Google) and i got some idea. Here is the solution to remove mootools from joomla

$document =& JFactory::getDocument();
foreach ($document->_scripts as $key=>$val) {
if (stripos($key, 'mootools.js') !== false) {
unset($document->_scripts[$key]);
}
}

Similar way we can remove any js , just replace with 'mootools.js' with 'yourjsname'.

Filelist params in joomla

In joomla we have the options to add the params in all extension, based on this params setting we can controll our extenstion output. Here we going to see about list your component layouts using file list params

<param name="layout_file" type="filelist" default="default" label="Select a layout" description="" directory="administrator/components/your_component/views/your_view/tmpl" filter="" exclude="" stripext="" />

This will list your layouts in that view.

stripext : set to 1 to strip the file extension in that list

exclude  : a regular expression will exclude the files from the list.

filter   : a regular expression to filter on lists all files based on extension.

(eg) filter=?\.html$?

Dynamic positions in joomla template

In joomla one of the best extension is template, in template we can add number of position based on our site requirements. Here i am going to explain how we add/remove positions dynamically based on content. if you need to display the position only in that position module have content. Here is the easy way to do it

$doc =& JFactory::getDocument(); 

$buffer=$doc->getBuffer( 'modules', 'positionname', array());

if (!empty($buffer)) {

<jdoc:include type="modules" name="positionname" />

}

based on the above code you can easily enable or disable the position dynamically in joomla template.

(ex)

$doc =& JFactory::getDocument();
$buffer=$doc->getBuffer( 'modules', 'right', array());

if (!empty($buffer)) {
<jdoc:include type="modules" name="right" />
}

if the right position modules content not empty mean right position will load in your template similar to other postion.

Joomla1.6 installer xml changes

Compare to joomla 1.6 with joomla 1.5 they changed the parameters defined way in xml file. These changes apply to all extensions modules, plugins, component etc..

1. <params> replaced with <config><fields name="params"><fieldset name="basic">
2. <param> replaced with <field>
3. <install replaced with <extension
   (ex) <extension type="module" version="1.6.0" client="site" method="upgrade">

Remove lock in joomla articles

In joomla some time we get lock image in article ,category , modules etc..

if it locked mean some one other than you using it or it not closed by prober way. In joomla 1.6 have option as "Check in" button at the top of the listing page, we can just check what are the things need to unlock it and click the button then the lock will removed.

In joomla1.5 we don't have that option but we can do it by a query , just rest the 'checked_out' filed to '0', then the lock will removed.

for example if you got your article locked but no one accessed that mean , just run this query

update jos_content set checked_out=0 where id = your_article_id;


if you want to apply this to all mean just remove the where that's it.

Three important position in joomla template

There are four main extensions in joomla.

1.  Component
2. Module
3. Plugins
4. Template

Here i am going to discuss about template. Template change the way of presenting your sites. You can split the page with number columns (left, right, middle) and rows (header, content, middle). In joomla we have a future to load the content using jdoc. Using jdoc you can position the above there extensions(Component, module and plugin) output. Using jdoc you can easily set it.

How to add jdoc?
            There is no magic for this , you can add it via a simple HTML type notation.

<jdoc:include type=”specifictype”/>

Here I list out what are the important jdoc types

1.      Head

2.      Message

3.      Component

These three element should appear only one time in page.

Head:
            Header jdoc this will add with in <head>….</head> tag. This will load the meatadata, style and scripts.

<jdoc:include type=”head”/>

Message:
            This will used to render errors in each request. Using this we can display the error, notice and warning messages from mainframe redirect/enque messages.

<jdoc:include type=”message”/>

Component:
            Component act a main roll in joomla. You can render the component output using this jdoc

<jdoc:include type=”component”/>
