Body
Smarty is a PHP template engine for PHP, which facilitates the separation of presentation (XHTML/CSS) from the PrestaShop's core functions/controllers. A template file (usually with a .tpl extension in PrestaShop) is always called by a PHP controller file (it can be a Front-end core controller or a module controller). Example: <code>/prestashop/controllers/front/ContactController.php</code> <pre><code>$this->context->smarty->assign(array( 'contacts' => Contact::getContacts($this->context->language->id), 'message' => html_entity_decode(Tools::getValue('message')) )); $this->setTemplate(_PS_THEME_DIR_.'contact-form.tpl'); </code></pre> We can see that this file is retrieving information from the database and assigning it to Smarty. Then, the 'contact-form.tpl' template will display it to the visitors. The syntax is pretty similar for modules, example:<code>/prestashop/modules/blocklink/blocklink.php</code> <pre><code>public function hookLeftColumn($params) { $this->smarty->assign('blocklink_links', $this->getLinks()); return $this->display(__FILE__, 'blocklink.tpl'); } </code></pre> Also, to store values in Smarty variables, you can use the 'assign' function in two ways: <ol> <li><code>$this->context->smarty->assign('my_smarty_variable_name', $my_value);</code> or if you have several variables:</li> <li><code>$this->context->smarty->assign(array('my_smarty_variable_name1' => $my_value1), ('my_smarty_variable_name2' => $my_value2));</code></li> </ol> And then in the Smarty template: <pre><code>The value of my variable is {$my_smarty_variable_name|escape:'htmlall':'UTF-8'}. </code></pre> The 'escape' modifier is used to avoid XSS security issues.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
