[Solved] My modules does not load the template to render


Recommended Posts

Hello :)


I created and installed a module and I can see it in the live edit position window, but it does not render any content.


This is my module.


if (!defined('_PS_VERSION_')) {
require __DIR__ . '/DbManager.class.php';
class AdvancedSearchModule extends Module
public function __construct()
	$this->name		  = 'advancedsearchmodule';
	$this->tab		   = 'Search';
	$this->version	   = 1.0;
	$this->author		= 'Egidio Caprino';
	$this->need_instance = 0;
	$this->displayName = $this->l('Advanced Search');
	$this->description = $this->l('Allow user to search for attributes.');
public function install()
	if (!parent::install() || !$this->registerHook('top') || !$this->registerHook('displayHome')) {
		return false;
	return true;
public function hookTop($params)
	global $smarty;
	$smarty->assign('features', $this->getFeatures());
	return $this->display(__FILE__, 'top.tpl');
public function hookDisplayHome($params)
	global $smarty;
	$features = $this->getFeatures();
	$smarty->assign('features', $features);
	$this->display(__FILE__, 'home.tpl');
public function uninstall()
	if (!parent::uninstall())
		Db::getInstance()->Execute('DELETE FROM ' . _DB_PREFIX_ . 'advancedsearchmodule');
private function getFeatures()
	$lang = (int) $this->context->language->id;
	$db	 = DbManager::getInstance();
	$query  = 'SELECT id_feature, name FROM ' . _DB_PREFIX_
			. 'feature_lang WHERE id_lang = ' . $lang
			. ' ORDER BY name ASC';
	$result = $db->query($query);
	$features = array();
	while ($row = mysql_fetch_array($result, MYSQL_NUM)) {
		$features[$row[0]] = array(
			'name'   => $row[1],
			'values' => array()
	$query = 'SELECT ' . _DB_PREFIX_ . 'feature_value.id_feature_value, '
		   . _DB_PREFIX_ . 'feature_value_lang.value FROM '
		   . _DB_PREFIX_ . 'feature_value INNER JOIN '
		   . _DB_PREFIX_ . 'feature_value_lang ON ' . _DB_PREFIX_
		   . 'feature_value.id_feature_value = ' . _DB_PREFIX_
		   . 'feature_value_lang.id_feature_value WHERE id_lang = '
		   . $lang . ' AND ' . _DB_PREFIX_
		   . 'feature_value.id_feature = %s ORDER BY '
		   . _DB_PREFIX_ . 'feature_value_lang.value ASC';
	foreach ($features as $id_feature => $name) {
		$result = $db->query(sprintf($query, $id_feature));
		while ($row = mysql_fetch_array($result, MYSQL_NUM)) {
			$features[$id_feature]['values'][$row[0]] = $row[1];
	return $features;


This is my home.tpl file placed in the same root of the file above.


<h1> HOOK HOME </h1>

I did it. I can transplant the module in the header and in the top. I cannot transplant it the center column (displayHome).


I checked and the code under the hookDisplayHome function is executed. It just does not dysplay the home.tpl. This file is in the module dir. Is that position correct? I don't understand.

I did it but it still not working. The code in that function is executed but the home.tpl is not diplayed.


Is the problem in this line '$this->display(__FILE__, 'home.tpl');'? The home.tpl file is in the same directory of the module class.
