In the part 4, I will present and explain the purpose FlexicontentViewItems that will allows us to achieve our template for Item. And so I will detail all the variables that can be helpful in building your own templates.

I will also talk about a lot of functions that can be found with the class flexicontent_html.

This tutorial is always built around my example will display information about a football stadium.

The FLEXIcontentViewItems

This object is usable in all template in Item view, and will allow you to bring up all the information related to content.
It is accessible through the variable $this.
I now resume my item.php file (created in the part1 of this tutorial) and I will begin by reviewing the header of my.

// interdit l'accés direct au fichier
 defined( '_JEXEC' ) or die( 'Restricted access' );
 // on définit ici le nom du template, dans notre cas :.items.stade
 $tmpl = $this->tmpl

We will then introduce our template set with a div tag by adding customized css class depending on the stadium and type of content. For this I use:
$this->item->id = returns the identifier of the content
$this->item->type_id = returns the identifier of the type of content

It gives that :

<div id="stade_contenu" class="stade_contenu itemitem->id; ?> typeitem->type_id; ?>">

Display a set of content field at a specific position
