Joomla Featured Image PHP Call - templates

I'm developing my templates for Joomla and I'm needing to get the URL of the 'Featured Image' of an article. Is there a special Joomla PHP call to get this as a variable?

AFAIK, You cannot get this directly in the template's index.php file, but you can access it using the template's overrides. So start by creating a HTML folder within your template, then within that folder copy the folders you wish to override.
So for the image url, copy the following file
components/com_content/views/article/tmpl/default.php
to
templates/yourtemplatename/html/com_content/article/default.php
and then within that file you can access use / access the image url.

Simple answer is No, an Articles image and URL's values are part of the articles params and are stored as a JSON string. You can find more about accessing them in this answer
The article content (or main component content) of a page in Joomla is displayed by the component, so to display the article content in a custom way a template needs to create it's own overrides for each component or module that it wants to change the appearance of. This is what #mozami was talking about.

Typo3 / blank Templates

I'm a greenhorn with typo3 templating. Actually I'm using "bootstrap_package" (standard layout). I would like to create a sub-page without logo, menu and footnote. I just want to have the content elements on a blank page. How do I do this? Can anyone help me?
Best regards

You should give some more information why you need such a special rendering to get some more detailed help.
The usual reasons for such a page are design flaws as there are more suitable solutions inside TYPO3.
In general: You need to create a new page rendering, where you switch off the generation of the HTML header.
add on:
make a page where you collect all the pages which should be available in this special rendering. This page should be a subpage from your root-page. regarding relaurl: [x] exclude from path
in this page create a typoscript template record.
as these pages need only one rendering I propose to modify the default page object instead of creating a new page object (with a new typeNum).
in the setup field of this template record remove all headers with:
config.disableAllHeaderCode = 1
You might need to disable further CSS and JS, especially if they are loaded at the end of the page.
if you need another html-markup than the default you can modify the configuration here: wraps, (fluid-)templates, ...
Then add your special pages with content.

How can I create a plugin to insert templated html within a text plugin in Django CMS

I'm fairly new to Django CMS so please forgive me if my terminology isn't right.
I have a page with a placeholder within which I have added some html using the Text plugin. Within that, I would like to be able to add one or many pre-templated pieces of html.
I have looked into building my own plugin but the documentation that I've been reading here only allows the plugin to be added from outside the actual text plugin page and renders the result beneath my text plugin content. I've found the section on Nested Plugins, but I'm trying to nest my plugin within the built-in Text plugin which that doesn't seem to cover.
What I'm looking for is to be able to build something so that it places block-level html elements within the content like the Link or Image plugins (in my case, it would be some block-level html content).
How can I do this, or where can I find some more information on how this can be done?

Joomla 3 Template override a plugin

I could not find any info on overriding a Joomla plugin in my template.
Some forums claimed there was no plugin override, and the Joomla documentation (being the menacing forest that it is) either has nothing on the subject, or the page is hard to find.
So how can we override the output of a Joomla plugin in the same was we override the output of com_content or mod_contact?
I have found a way to do this:
Navigate to <joomla_homefolder>/administrator/language/<your_language>/
Search for the plugin's corresponding language file.
Copy the file name, EXCLUDING the language prefix (ie en-GB.) and the .ini suffix.
In your template create a folder named html (a common practice for template overrides).
In the html folder create a subfolder and name with the language file name as you copied it in step 3.
Navigate to the tmpl subfolder in the plugin's path: <joomla_homefolder>/plugins/<plugin_type>/<plugin_name>/tmpl
Copy the view file you wish to override into the folder you've created in step 5.
Modify the copied file to override the plugins output.
For example -
To change the page navigation buttons - modify the output of <joomla_homefolder>/plugins/content/pagenavigation:
Go into <joomla_homefolder>/administrator/language/en-GB/ and find the file named en-GB.plg_content_pagenavigation.ini.
From the filename copy only plg_content_pagenavigation.
Create a folder named html (If it does not exist already) in your theme, inside it create a subfolder and name it plg_content_pagenavigation.
Copy the view file <joomla_homefolder>/plugins/content/pagenavigation/tmpl/default.php into the plg_content_pagenavigation folder you just created.
Modify the file.
Note: I have tried it only with Joomla 3.1.
The method may not work with some plugins.
Good Luck.
In joomla 3 you can override plugins output only, that's why the origin plugin must be implemented with a tmpl.
The naming convention of the folder in you [template]/html is
plg_[type*]_[pluginElement]
Template overridden native joomla plugins is only the pagenavigation.
type* : obviously there's no sense to be other than content but if it's custom plugin no one can stop you.
On a Joomla 3.1 install, I am using the Simple Image Gallery plugin and I felt the need to override it in order to add extra functionality to each thumbnail of the gallery.
I copied all of the contents of <joomla_homefolder>/plugins/content/jw_sig/jw_sig/tmpl/ into the folder <joomla_homefolder>/templates/protostar/html/jw_sig/ and I was then able to modify both the default.php file for output modifications, and the accompanying template.css file for styling modifications. This successfully overrides the plugin's output without risking issues during future updates.
Of course, this will not work with all plugins, but it offers another alternative if you have a plugin that was nice enough to be developed with a tmpl folder.
No you can't override the same way because there is not tmpl folder because plugins really should not be rendering though of course a lot do. You probably need to clone the plugin and make a the layout your want possibly using a jlayout to make it easier to manage.
Elin's answer is not quite correct for Joomla 2.5-3.x. Some plugins do render screen output and have /tmpl folders that you may be able to override. See http://docs.joomla.org/Layout_Overrides_in_Joomla
In some cases you may need to create alternative views within the plugin /tmpl folder. For example, some of the simple, newer custom content components that use JForms let you add fields to com_content articles and select a view template for each field. Then overrides for com_content are generated dynamically to display the custom fields. Each field type can be displayed in the component area through plugins, or in a module, or within the template code, but it will use the /tmpl file you selected for the field in the CCK component. If there is a way to override the different field views from within the template folder, it must require an arcane menu structure I haven't been able to discover.

Change Joomla Template parameters

Im developing an e-commerce with Joomla 2.5 using a template which has a slideshow embedded (not a module).
I want to create an article where the client himself can easily upload images and their descriptions and urls for the slideshow.
I've managed to load a file uploader module in an article and it works. But I don't know how to change the descriptions and urls.
The descriptions and urls are template parameters and I don't know how to set them from the article.
The params.ini file in template folder is blank.. The .xml shows the 's for them but not their current value.
You are getting two functions to work, but you're missing the whole logic that links images to pages, and assigns them names, possibly manage a little security.
Why do you want to build this from scratch? You'd be so much better off with a ready-made, free, tested and supported CCK (e.g. contentbuilder, k2, sobi, zoo just to name a few).

How to correctly modify <HEAD> in Django-CMS for custom plugins?

Django-CMS custom plugins and navigation extenders allow to create any content HTML in some part of the HTML . However I frequently have some JavaScripts required for some specific plugins, like a photo album viewer plugin that requires a JS in the .
My current solution is to let the user specify a specific template for that. I could do some checking in the template render() to use a specific placeholder or use placeholder restrictions but that doesn't seem right: It's still in the "body" placeholder.
Any suggestion?
Nothing wrong with including Javascript in the body - in fact, some consider it best practice.
