Using Twig for templating

For more complex elements you might want to use a html template. WPooW comes embedded with the twig template engine (which is used to render the predefined elements). The template engine can also be used to render your custom elements.

Using the examples above we could the change the ReadView and the EditView to the following:-

// Example
function ReadView($post)
{
    echo $this->twigTemplate->render('/read_view.twig',
                                    ["value" => $this->GetDatabaseValue($post)]);
}


function EditView( $post)
{
   parent::EditView($post);
   echo $this->twigTemplate->render('/edit_view.twig', [
       "id" => $this->id,
       "label" => $this->label,
       "value" => $this->GetDatabaseValue($post)
   ]);
}

In the examples above we are saying use the template read_view.twig / edit_view.twig to render this elements with the parameters value...etc. The location of the template files is relative to the php file of your custom element (unless in the construction of the element you specify a different elementPath See Elements Overview Above)
