How to retreive the value of system configuration?

In "Joomla -> Administrator -> Site -> System", the admin can specify a value for "Path to Media Folder". What PHP code can I put in my template that would allow me to retrieve that value?

Searching through the code, I found a few places that do something like this:

.../templates/beez/html/com_content/category/blog.php

Code:

$cparams = JComponentHelper::getParams ('com_media');
...
$cparams->get('image_path');

I think the parameter you want is file_path:
.../administrator/components/com_media/config.xml

So you would do something like:

Code:

$cparams = JComponentHelper::getParams ('com_media');
...
$cparams->get('file_path');

Let me know if you get it working. I haven't tested it myself.

It works. Thanks.

I used a more concise form ...

Code:

JComponentHelper::getParams('com_media')->get('file_path');

Cool. Glad it worked!

Hoping you can help with similar request. I am trying to use image set in the menu to display elsewhere, but for the life of me I can't find it. I can see the param in MySQL table jos_menu, but I can't get it directly from com_menu ... the following doesn't work:

Code:

$article_image = &JComponentHelper::getParams( 'com_menus' )->get( 'menu_image' );

but this does, with custom param in com_content (from viewtopic.php?f=178&t=320017):

Code:

$article_image = &JComponentHelper::getParams( 'com_content' )->get( 'article_image' );

Thanks!

I'm guessing that the menu_image parameter is associated with the menu item and not the actual component. If you let me know where you are trying to use this, I might be able to help.

For a reference, I would look at the mod_mainmenu code:
.../modules/mod_mainmenu/helper.php

Code:

$iParams = new JParameter($tmp->params);
if ($params->get('menu_images') && $iParams->get('menu_image') && $iParams->get('menu_image') != -1) {
...
   $image = '<img src="'.JURI::base(true).'/images/stories/'.$iParams->get('menu_image').'" '.$imgalign.' alt="'.$item->alias.'" />';

Let me know if you need more help figuring it out.

Really appreciate the help! You are correct, what I am after is associated with the menu item param menu_image. I want to display it in the root template index.php file \templates\custom\index.php (I have modified the ja_purity template thinking it would be easy to support and update going forward).

I'm very familiar with php and MySQL so this simple function is very frustrating for me. I'm new to joomla and so far unable to find anything to help me query the database in the documents / forums. I need to know how to query the database and I'm thinking that joomla has an easier method than making standard mysql_query ... am I right?

You are correct:
http://api.joomla.org/Joomla-Framework/Database/JDatabase.html

And there are some other classes that might have functions that would interest you:
http://api.joomla.org/Joomla-Framework/Application/JApplication.html#getMenu

I would really suggest looking through the mod_mainmenu to see how they are doing things and try to borrow from them.

If you have any specific questions or need more help, let me know.

Thank You! You really know how to point a guy in the right direction. I found the answer I was looking for by searching jmenu, though the documantaion is pretty much empty it pointed me to /libraries/joomla/application/menu.php - which is the same as the Developer API link you provided.... and then it all came together with the forum post and solution here viewtopic.php?f=304&t=259391&start=0

The following code in the template root index.php file will get the active menu_image. This code along with the code for getting custom article images is my ideal soultion as I now have a header picture for every page either from the menu or the articles themselves. It's a beautiful thing!

Code:

$menu       =& JSite::getMenu();
$item       =  $menu->getActive();
$params     =& $menu->getParams($item->id);
$menu_image =  $params->get( 'menu_image' );

Awesome. Glad I could help.

I use the api.joomla.org site a lot to quickly see function definitions, but it's nice to just be able to open the files themselves and look directly at the code. One of the many benefits of Open Source!
