Creating a module with both front-end and back-end controllers
Creating a new data table
Add a new table to your PrestaShop database. Name this table ps_opinion.
id_opinion | int(10) unsignedid_customer | int(10) unsignedopinion | enum('AVERAGE','GOOD','VERY_GOOD')active | tinyint(1) unsigned
Creating the model
Variables
/* models/opinion.php */class Opinion extends ObjectModel{ public $id_opinion; public $id_customer; public $opinion; public $active;
Model definition
public static $definition = array( 'table' => 'opinion', 'primary' => 'id_opinion', 'multilang' => false, 'fields' => array( 'id_opinion' => array( 'type' => ObjectModel :: TYPE_INT ), 'id_customer' => array( 'type' => ObjectModel :: TYPE_INT, 'required' => true ), 'opinion' => array( 'type' => ObjectModel :: TYPE_STRING, 'required' => true ), 'active' => array( 'type' => ObjectModel :: TYPE_BOOL, required' => true ) ));
Functions
public static function findAll() { $sql = 'select * from ' . _DB_PREFIX_ . 'opinion where active = 1'; if ($rows = Db :: getInstance(_PS_USE_SQL_SLAVE_)->ExecuteS($sql)) { return ObjectModel :: hydrateCollection(__CLASS__, $rows); } return array(); } public function getCustomerName() { $customer = new Customer($this->id_customer); return $customer->firstname . ' ' . $customer->lastname; }}
Creating the module's bootstrap file
<?phprequire_once dirname(__FILE__) . '/models/Opinion.php';class CustomerOpinion extends Module{ public function __construct() { $this->name = 'customeropinion'; $this->tab = 'front_office_features'; $this->version = 1.0; $this->author = 'Me'; $this->displayName = $this->l('Customer Opinion'); $this->description = $this->l('Customer Opinion'); parent::__construct(); } public function install() { return parent::install() && $this->registerHook('leftColumn'); } public function hookDisplayLeftColumn($params) { return $this->display(__FILE__, 'left-column.tpl'); }}
Creating the hook's view
The left-column.tpl file is located in the /views/templates/hook folder.
{* Filename: left-column.tpl *}<a href="{$link->getModuleLink('customeropinion')}">{l s='Give my opinion' mod='customeropinion'}</a>
The getModuleLink() function makes it possible to add a link to the module's controller.
Here is its signature: $link->getModuleLink($module, $controller = 'default', array $params = array(), $ssl = false, $id_lang = null)
Creating the front-office controller
The module's controller, default.php, is located in the /controllers/front folder.
class helloWorldDefaultModuleFrontController extends ModuleFrontController{ public function initContent() { parent::initContent(); if ($_SERVER['REQUEST_METHOD'] == 'POST') { if ($opinion = Tools::getValue('opinion', false)) { $opinionObj = new Opinion(); $opinionObj->id_customer = $this->context->customer->id; $opinionObj->active = false; $opinionObj->opinion = $opinion; $opinionObj->add(); $link = new Link(); Tools::redirect($link->getModuleLink('customeropinion', 'default')); } } $opinions = Opinion::findAll(); $this->context->smarty->assign('opinions', $opinions); $this->setTemplate('form.tpl'); }}
The template for the controller, form.tpl, is located in the /views/templates/front folder.
<h2>{l s='Give your opinion' mod='customeropinion'}</h2><form method="post" class="std"> <fieldset> <label for="opinion" id="opinion">{l s='Our website is...' mod='customeropinion'}</label> <select name="opinion"> <option>--</option> <option value="VERY_GOOD">{l s='Very Good' mod='customeropinion'}</option> <option value="GOOD">{l s='Good' mod='customeropinion'}</option> <option value="AVERAGE">{l s='Average' mod='customeropinion'}</option> </select> <input type="submit" class="button" value="{l s='Give my opinion' mod='customeropinion'}" /> </fieldset></form><hr /><h3>{l s='What people think' mod='customeropinion'}</h3><table style="width: 100%;"> {foreach from=$opinions item=opinion} <tr> <td>{$opinion->getCustomerName()}</td> <td>{$opinion->opinion}</td> </tr> {/foreach}</table>
Creating the back-office controller
The module's controller, AdminOpinion.php, is located in the /controllers/admin folder.
By convention, all back-office controllers should be named with the "Admin" prefix.
class AdminOpinionController extends ModuleAdminController{ public function __construct() { $this->table = 'opinion'; $this->className = 'Opinion'; parent::__construct(); $this->fields_list = array( 'id_opinion' => array( 'title' => '#' ), 'id_customer' => array( 'title' => $this->module->l('Customer'), 'callback' => 'getCustomerName' ), 'opinion' => array( 'title' => $this->module->l('Opinion') ), 'active' => array( 'title' => $this->module->l('Valider'), 'active' => 'status' ) ); $this->actions = array('delete'); } public function getCustomerName($echo, $row) { $id_customer = $row['id_customer']; $customer = new Customer($id_customer); return $customer->firstname . ' ' . $customer->lastname; }}
Adding the controller to the back-office
In its current state, the module's controller will not appear automatically in the back-office interface: you have to add it yourself, manually.
This is done using the tool in the "Menus" pages, under the "Administration" menu. See the documentation for this page in the PrestaShop 1.5 User Guide.
