在Header.tpl文件中有一个钩子{$HOOK_TOP}，其中包含所有标题部分，包括菜单、搜索等...您可以在此 URL 中检查
在FrontController它显示... 'HOOK_TOP' => Hook::exec('displayTop')，这意味着在 Hook 页面中有一个名为 的函数exec()。但我无法正确理解exec()通话中的代码。
它告诉它为指定的钩子执行模块。当我搜索“ displayTop ”时，我得到了一个名为blocktopmenu.php.
执行仅通过 2 个功能：
public function hookDisplayTop($param)
{
$this->user_groups = ($this->context->customer->isLogged() ? $this->context->customer->getGroups() : array(Configuration::get('PS_UNIDENTIFIED_GROUP')));
$this->page_name = Dispatcher::getInstance()->getController();
if (!$this->isCached('blocktopmenu.tpl', $this->getCacheId()))
{
$this->makeMenu();
$this->smarty->assign('MENU_SEARCH', Configuration::get('MOD_BLOCKTOPMENU_SEARCH'));
$this->smarty->assign('MENU', $this->_menu);
$this->smarty->assign('this_path', $this->_path);
}
$this->context->controller->addJS($this->_path.'js/hoverIntent.js');
$this->context->controller->addJS($this->_path.'js/superfish-modified.js');
$this->context->controller->addCSS($this->_path.'css/superfish-modified.css');
$html = $this->display(__FILE__, 'blocktopmenu.tpl', $this->getCacheId());
//print_r($html);//exit;
return $html;
}
和
protected function getCacheId($name = null)
{//echo"asdasdsad";exit;
parent::getCacheId($name);
$page_name = in_array($this->page_name, array('category', 'supplier', 'manufacturer', 'cms', 'product')) ? $this->page_name : 'index';
return 'blocktopmenu|'.(int)Tools::usingSecureMode().'|'.$page_name.'|'.(int)$this->context->shop->id.'|'.implode(', ',$this->user_groups).'|'.(int)$this->context->language->id.'|'.(int)Tools::getValue('id_category').'|'.(int)Tools::getValue('id_manufacturer').'|'.(int)Tools::getValue('id_supplier').'|'.(int)Tools::getValue('id_cms').'|'.(int)Tools::getValue('id_product');
}
但是这个公共函数hookDisplayTop($param)永远不会在任何地方的整个文件夹中被调用。我搜索了它，但从未在任何文件中找到它。
exec()功能如下图
public static function exec($hook_name, $hook_args = array(), $id_module = null, $array_return = false, $check_exceptions = true)
{
// Check arguments validity

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'] = $context->cookie;
if (!isset($hook_args['cart']) || !$hook_args['cart'])
$hook_args['cart'] = $context->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 && $id_module != $array['id_module'])
continue;

continue;
// Check permissions
if ($check_exceptions)
{

if (isset($matching_name[$controller]) && in_array($matching_name[$controller], $exceptions))
continue;
if (Validate::isLoadedObject($context->employee) && !$moduleInstance->getPermission('view', $context->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 || $hook_retro_callable) && Module::preCall($moduleInstance->name))
{
$hook_args['altern'] = ++$altern;

{
$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 ? '<script type="text/javascript">hooks_list.push(\''.$hook_name.'\'); </script>
<div id="'.$hook_name.'" class="dndHook" style="min-height:50px">' : '').$output.($live_edit ? '</div>' : '');// Return html string
