Is there a way to manually configure the contents of the <head> section of the site in Joomla 3.1? I want to use the templating system for the entire markup of the page, including everything between <html></html>.
I just read this: http://forum.joomla.org/viewtopic.php?f=466&t=230787 and I am astonished at the response. Surely this is template/data separation 101. Has this been fixed in the latest Joomla release?
If you are planning for a template development and you need all your template data get separated from Joomla libraries or core file (the head section).
Normally the head section include will works like
<jdoc:include type="head" />
it loads the content from libraries libraries\joomla\document\html\renderer\head.php
If you want to override the content of head you can make a module for your task.
Just create a module and include that module instead of this head make sure that have all required codes added to work $document Class otherwise it miss a lot off features of Joomla regarding document class
As explained by the answer from Jobin, normally, you would include the head data by using the <jdoc:include type="head" /> tag, but if you want more control over this, you can use the JDocument.
Example code in your template's PHP:
$doc = JFactory::getDocument();
$my_head_data = $doc->getHeadData();
This will give you an array of the data that JDocument would normally print, so that you can completely choose what to print and how.
To make jQuery load from CDN and get it on top of the script list, I made a little patch just after the $doc = JFactory::getDocument(); that manipulates the header array directly inside the $this object as follows:
$my_jquery = "//ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js";
$my_jquery_ui = "//ajax.googleapis.com/ajax/libs/jqueryui/1.11.2/jquery-ui.min.js";
$my_jquery_cx = $this->baseurl."/media/jui/js/jquery-noconflict.js ";
foreach($this->_scripts as $k=>$v) {
// put own jquery.conflict && jquery-ui && jquery on top of list
if( strpos($k,'jquery.min.js')) {
unset($this->_scripts[$k]);
$r = array( $my_jquery_cx => $v);
$this->_scripts = $r + $this->_scripts;
$r = array( $my_jquery_ui => $v);
$this->_scripts = $r + $this->_scripts;
$r = array( $my_jquery => $v);
$this->_scripts = $r + $this->_scripts;
}
else if( strpos($k,'jquery.ui.min.js')) {
unset($this->_scripts[$k]);
}
else if( strpos($k,'jquery-noconflict.js')) {
unset($this->_scripts[$k]);
}
}
Replace $my_jquery_xxx with editable config parameters in your templateDetails.xml file

I have use codeiginter pagination functionality. But I want pagination url with out href url link in codeiginter. how can possible please help?
you can play with Pagination library , create your own library like so
application/libraries/Pagination.php
and copy the content of CI native pagination library file into the file that you just created from
system/libraries/Pagination.php
so this way you don't touch core files
then search for "here we go..." in my version it is on line 225
underneath you can see how those links are rendered and you can change them as you wish
// And here we go...
$output = '';
// Render the "First" link
if ($this->first_link !== FALSE AND $this->cur_page > ($this->num_links + 1))
{
$first_url = ($this->first_url == '') ? $this->base_url : $this->first_url;
$output .= $this->first_tag_open.'<a '.$this->anchor_class.'href="'.$first_url.'">'.$this->first_link.'</a>'.$this->first_tag_close;
}
.... etc
you can read more about Replacing and extending Native Libraries with Your Versions here http://www.codeigniter.com/userguide2/general/creating_libraries.htmll
hope that helps!
In my component view, I can show a module by this code:
$module = JModuleHelper::getModule('mod_login');
$html = JModuleHelper::renderModule($module);
echo $html;
or
echo JHtml::_('content.prepare', '{loadmodule login}');
But that will usually place the module in the middle of the screen in the main-content div.
How can I place the module in the position defined in the module params?
Take a look at how the admin template Isis renders the quickicons module on the home page or at how the error page in protostar renders the search modules.
$this->searchmodules = JModuleHelper::getModules('position-0');
foreach ($this->searchmodules as $searchmodule)
{
$output = JModuleHelper::renderModule($searchmodule, array('style' => 'none'));
$params = new JRegistry;
$params->loadString($searchmodule->params);
echo $output;
}
You just want one module, but you get the basic idea.
Try This.
You can Pass the module parameters too.
$document = &JFactory::getDocument();
$renderer = $document->loadRenderer('module');
$Module = &JModuleHelper::getModule('mod_fmDataGrid');
$Params = "param1=bruno\n\rparam2=chris";
$Module->params = $Params;
echo $renderer->render($Module);
This may help you..
You can't, jdoc includes in the template are processed after the component has finished producing its output.
Why not let Joomla render the modules in the right positions? that should be one of the reasons for using it, i.e. taking care of placement and order of modules.
If you have other reasons for doing this, please explain further.
Because pagination is using getUserStateFromRequest method to get the limit and limitstart variable, I'm having a problem where as I navigate from one component to another, I'm shown a no items found message.
To clarify, I have a products component that has 3 pages worth of products listed. Then I have a branches component with 2 pages worth of branch information. So if I navigate to the third page in the products list, and then go to the branches component, nothing is displayed.
Has anyone any idea how to stop this from happening? Any way to maybe clear the session data?
What I ended up doing was this,
in line 624 in libraries/joomla/application/application.php file I added the following lines
$this->setUserState('option','default');
$curr_comp = JRequest::getCmd( 'option' );;
if($this->getUserState('option') != $curr_comp)
{
$this->setUserState($option . 'limitstart',0);
$this->setUserState('option',$curr_comp);
}
so the whole function reads this,
public function getUserStateFromRequest($key, $request, $default = null, $type = 'none')
{
$this->setUserState('option','default');
$curr_comp = JRequest::getCmd( 'option' );
if($this->getUserState('option') != $curr_comp)
{
$this->setUserState($option . 'limitstart',0);
$this->setUserState('option',$curr_comp);
}
$cur_state = $this->getUserState($key, $default);
$new_state = JRequest::getVar($request, null, 'default', $type);
// Save the new value only if it was set in this request.
if ($new_state !== null)
{
$this->setUserState($key, $new_state);
}
else
{
$new_state = $cur_state;
}
return $new_state;
}
This seems to be working fine at the moment. But please test before implementing on a live site
To prevent editing the core files, but with the effect limited to your extension (so other extensions could load at the wrong page, but not yours), and if your model extends modellist, override the getStart() method:
public function getStart()
{
$store = $this->getStoreId('getstart');
$input = JFactory::getApplication()->input;
$start = $limitstart = $input->getInt('limitstart', 0);
$this->setState('list.start', $limitstart); // maybe redundant
$limit = $this->getState('list.limit');
$total = $this->getTotal();
if ($start > $total - $limit)
{
$start = max(0, (int) (ceil($total / $limit) - 1) * $limit);
}
// Add the total to the internal cache.
$this->cache[$store] = $start;
return $this->cache[$store];
}
If you want a solution that works system-wide and for all extensions, you should be able to override modellist with your implementation in a plugin. Start here.
This is an old question, but I just had the same issue as the OP, but in my case with Joomla 3.4.3.
After a lot of digging and testing, I discovered a solution for this that doesn't involve any plugin or core change:
If you put limitstart=0 in the URL, the pagination will restart for that page, and this solves the problem between menus.
The way to implement this could be either with javascript, or by overriding the menu module, I chose the override:
I just need this in some menus, so I placed a CSS class into the
menu link (edit the menu, and in the "Link Type" tab, place the CSS
class in the "Link CSS Style" field), in my case it was "
video-area" (without the quotes).
Add override (add the module to the html folder of your template,
in my case it was the menu module, so it was a matter of adding the
mod_menu folder: templatefolder/html/mod_menu)
In the override of the component part of the module
(default_component.php), check to see if we have the CSS class, if
so, add the extra query to the URL (I edited case 0):
case 0: $paginationLinks = ""; if(isset($class) && strpos($class, '
video-area') !== false){ $paginationLinks =
"?limitstart=0&limit=12"; } ?><a <?php echo $class; ?>href="<?php
echo $item->flink; ?><?php echo $paginationLinks;?>" <?php echo
$title; ?>><span><?php echo $linktype; ?></span></a><?php break;
That's it! it solved my problem, and even the pagination links have the extra query :)
BONUS: notice that I have &limit=12, this changes the limit for the pagination into 12 per page, without any extra code!, (before, I had a lot of code to implement this, and by adding this to the menu it calculates the correct page number and totals, and filters the query, nice one Joomla!)
please help, I've a problem with Joomla's function renderModule.. I am trying to render module with this function, but it unfortunately strips javascript from the the rendered module.
I use the function in my own module which includes other modules according to current article..
The code is as following:
<?php
$moduleType = "j15html";
$moduleName = "test";
$option = JRequest::getVar( 'option', '' );
$view = JRequest::getVar( 'view', '' );
$id = JRequest::getInt( 'id', 0 );
$moduleName .= $id;
//echo $view;
if ( $option == "com_content" && $view == "article" ) {
//echo $moduleName;
$module = JModuleHelper::getModule($moduleType, $moduleName);
//print_r($module);
if ( ! empty( $module ) ) {
$attribs = array();
echo JModuleHelper::renderModule( $module, $attribs );
}
}
When I set the position of the included module to any position used in my template and set it to displat in particular menu section, it renders properly even with javascript and so on..
Any advices how to make this thing working?
You didn't mention which version of Joomla you're using - but you may want to check out SOURCERER it keeps coding how you put it and does not strip out extra coding.
Make sure you read the how-to so you know how to use it because it can seem a little confusing at first, but it has a button to 'change the tags' from < to << or [ which do not get stripped out by the WYSIWYG editor in Joomla!.
Of course, that could be your issue also, if your WYSIWYG editor is on (by default it is) and you're inputting code - it strips it. An easy way is to just turn it off under global options, then when you save the code doesn't get stripped. Just turning off the WYSIWYG editor is the quick/easy/simple solution - but if you turn it back on and open that module again, the code will be gone. So it can be a tricky solution if others may like using the editor or if you're using lots of custom code around your side. In that case the plugin I mentioned above is a great solution.
Folks, I am trying to implement a rudimentary feature in Joomla but having no luck getting my head around it.
My client has setup Joomla with several sections; each section having its own categories and eventually content underneath.
I need each section to have a slightly different color component (e.g. Section A and its all subsequent child pages red, Section B - blue, etc); certain borders and backgrounds need to be unique according to each section.
I have one theme which is used by all sections. Somewhere in the theme file, I need to detect which section I am on, and based on that set a css variable accordingly:
<html>
<body class="cars-section">
</body>
</html>
All I need is to set my body's class to the right section, and all my coloring has been setup to work magically.
Any ideas how this can be done in the Joomla world? Is there another way of doing such a thing.
You need to pick the section ID up from the request.
Use this to get the relevant request variables:
<?php
$option = JRequest::getWord('option', null);
$view = JRequest::getWord('view', null);
$idalias = JRequest::getVar('id', null);
if (strpos($idalias, ":") != false) {
$idandalias = explode(":", $idalias);
$id = $idandalias[0];
} else {
$id = JRequest::getInt ('id' , 0);
}
Then use something like this to see what section you are in, if you are on a section page:
if ( $option=="com_content" && $view=="section" ) {
$sectid = $id;
}
In section pages you can just use the request, but in other pages you need to do a database query as well:
else {
$database =& JFactory::getDBO();
if ( $option=="com_content" && $view=="category" ) {
$query = "SELECT section FROM jos_categories WHERE id=$id";
}
if ( $option=="com_content" && $view=="article" } {
$query = "SELECT sectionid FROM jos_content WHERE id=$id";
}
$database->setQuery($query);
$sectid = $database->loadResult();
}
When you have the section ID you can use it to set and insert the right class.
if ( $sectid == '3' ) {
$my_cars_section_class = 'three';
}
?>
<body class="<?php echo $my_cars_section_class; ?>">
Something like that should do it.
There are a couple of ways to achieve body css-classing:
Utilize Joomla's menu page class suffix system.
Output the class based on the selected menu link from within the template. Of course, if you plan to do this, you'll need to modify your template a bit.
$menu = &JSite::getMenu();
$active = $menu->getActive();
<body <?php if($active->alias) echo 'class="' .$active->alias .'"' ?>>
