    <p>In the <code>Header.tpl</code> file there is a hook <code>{$HOOK_TOP}</code> which contains all the header part including menu, search etc... You can check that in this URL </p> <p>In the <code>FrontController</code> it shows... <code>'HOOK_TOP' =&gt; Hook::exec('displayTop')</code>, it means in the Hook page there is a function called <code>exec()</code>. But I cannot understand the code properly in the <code>exec()</code> call.</p> <p>It tells it <em>Execute modules for specified hook</em>. When I searched for "<em>displayTop</em>" I got a module name called <code>blocktopmenu.php</code>.</p> <p>Execution only goes through 2 functions:</p> <pre><code> public function hookDisplayTop($param) { $this-&gt;user_groups = ($this-&gt;context-&gt;customer-&gt;isLogged() ? $this-&gt;context-&gt;customer-&gt;getGroups() : array(Configuration::get('PS_UNIDENTIFIED_GROUP'))); $this-&gt;page_name = Dispatcher::getInstance()-&gt;getController(); if (!$this-&gt;isCached('blocktopmenu.tpl', $this-&gt;getCacheId())) { $this-&gt;makeMenu(); $this-&gt;smarty-&gt;assign('MENU_SEARCH', Configuration::get('MOD_BLOCKTOPMENU_SEARCH')); $this-&gt;smarty-&gt;assign('MENU', $this-&gt;_menu); $this-&gt;smarty-&gt;assign('this_path', $this-&gt;_path); } $this-&gt;context-&gt;controller-&gt;addJS($this-&gt;_path.'js/hoverIntent.js'); $this-&gt;context-&gt;controller-&gt;addJS($this-&gt;_path.'js/superfish-modified.js'); $this-&gt;context-&gt;controller-&gt;addCSS($this-&gt;_path.'css/superfish-modified.css'); $html = $this-&gt;display(__FILE__, 'blocktopmenu.tpl', $this-&gt;getCacheId()); //print_r($html);//exit; return $html; } </code></pre> <p>and</p> <pre><code>protected function getCacheId($name = null) {//echo"asdasdsad";exit; parent::getCacheId($name); $page_name = in_array($this-&gt;page_name, array('category', 'supplier', 'manufacturer', 'cms', 'product')) ? $this-&gt;page_name : 'index'; return 'blocktopmenu|'.(int)Tools::usingSecureMode().'|'.$page_name.'|'.(int)$this-&gt;context-&gt;shop-&gt;id.'|'.implode(', ',$this-&gt;user_groups).'|'.(int)$this-&gt;context-&gt;language-&gt;id.'|'.(int)Tools::getValue('id_category').'|'.(int)Tools::getValue('id_manufacturer').'|'.(int)Tools::getValue('id_supplier').'|'.(int)Tools::getValue('id_cms').'|'.(int)Tools::getValue('id_product'); } </code></pre> <p>But this public function <code>hookDisplayTop($param)</code> never gets called in the whole folder anywhere. I searched it but never found it in any file.</p> <p>The <code>exec()</code> function shows below</p> <pre><code>public static function exec($hook_name, $hook_args = array(), $id_module = null, $array_return = false, $check_exceptions = true) { // Check arguments validity if (($id_module &amp;&amp; !is_numeric($id_module)) || !Validate::isHookName($hook_name)) throw new PrestaShopException('Invalid id_module or hook_name'); // If no modules associated to hook_name or recompatible hook name, we stop the function if (!$module_list = Hook::getHookModuleExecList($hook_name)) return ''; // Check if hook exists if (!$id_hook = Hook::getIdByName($hook_name)) return false; // Store list of executed hooks on this page Hook::$executed_hooks[$id_hook] = $hook_name; // print_r(Hook::$executed_hooks);exit; $live_edit = false; $context = Context::getContext(); if (!isset($hook_args['cookie']) || !$hook_args['cookie']) $hook_args['cookie'] = $context-&gt;cookie; if (!isset($hook_args['cart']) || !$hook_args['cart']) $hook_args['cart'] = $context-&gt;cart; $retro_hook_name = Hook::getRetroHookName($hook_name); //print_r($hook_name);exit; // Look on modules list $altern = 0; $output = ''; foreach ($module_list as $array) { // Check errors if ($id_module &amp;&amp; $id_module != $array['id_module']) continue; if (!($moduleInstance = Module::getInstanceByName($array['module']))) continue; // Check permissions if ($check_exceptions) { $exceptions = $moduleInstance-&gt;getExceptions($array['id_hook']); $controller = Dispatcher::getInstance()-&gt;getController(); if (in_array($controller, $exceptions)) continue; //retro compat of controller names $matching_name = array( 'authentication' =&gt; 'auth', 'compare' =&gt; 'products-comparison', ); if (isset($matching_name[$controller]) &amp;&amp; in_array($matching_name[$controller], $exceptions)) continue; if (Validate::isLoadedObject($context-&gt;employee) &amp;&amp; !$moduleInstance-&gt;getPermission('view', $context-&gt;employee)) continue; } // Check which / if method is callable $hook_callable = is_callable(array($moduleInstance, 'hook'.$hook_name)); $hook_retro_callable = is_callable(array($moduleInstance, 'hook'.$retro_hook_name)); if (($hook_callable || $hook_retro_callable) &amp;&amp; Module::preCall($moduleInstance-&gt;name)) { $hook_args['altern'] = ++$altern; // Call hook method if ($hook_callable) $display = $moduleInstance-&gt;{'hook'.$hook_name}($hook_args); else if ($hook_retro_callable) $display = $moduleInstance-&gt;{'hook'.$retro_hook_name}($hook_args); // Live edit if (!$array_return &amp;&amp; $array['live_edit'] &amp;&amp; Tools::isSubmit('live_edit') &amp;&amp; Tools::getValue('ad') &amp;&amp; Tools::getValue('liveToken') == Tools::getAdminToken('AdminModulesPositions'.(int)Tab::getIdFromClassName('AdminModulesPositions').(int)Tools::getValue('id_employee'))) { $live_edit = true; $output .= self::wrapLiveEdit($display, $moduleInstance, $array['id_hook']); } else if ($array_return) $output[] = $display; else $output .= $display; } } if ($array_return) return $output; else return ($live_edit ?

    1. COprobably the hook method is being called dynamically in the exec() method you already mentioned. Just post the contents of the exec() method and I'll give it a shot

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.
