[英]Override Prestashop Module Controller: Where to place php file?
我試圖覆蓋Prestashop中的模塊。 我已經成功覆蓋了模塊的模板,但是無法成功覆蓋模塊的控制器。
新的控制器類文件應放在何處?
我嘗試了以下位置,但它們未添加新行為(更改任何內容):
〜/ overrides / modules / blockwishlist / controllers / front / mywishlist.php
〜/ themes / MY_THEME / modules / blockwishlist / controllers / front / mywishlist.php
根據我之前的問題,我可以通過編輯核心類(由u / Sergii P推薦)來做到這一點,但是我確定有一種標准方法可以實現,而無需編輯核心類?
以供參考; 這是mywishlist.php
的內容:
<?php
if (!defined('_CAN_LOAD_FILES_'))
exit;
//class BlockWishListMyWishListModuleFrontController extends BlockWishListMyWishListModuleFrontControllerCore // extends ModuleFrontController
class BlockWishListMyWishListModuleFrontControllerOverride extends BlockWishListMyWishListModuleFrontController
{
public function __construct()
{
parent::__construct();
}
/**
* Assign wishlist template
*/
public function assign()
{
$errors = array();
....
$this->setTemplate('mywishlist.tpl');
}
}
編輯:我有一個可能的解決方法,無法覆蓋ModuleFrontController
類。 目的是在“我的願望清單”頁面上添加一個“導出到CSV”按鈕,單擊該按鈕時,服務器將生成一個包含該願望清單中所有產品的CSV文件。 在我完成所有工作之前,您能否提供關於是否可行的建議?
{hook h='displayExportToCsvColumn' mod='myCustomModule'}
BlockWishlist
( 〜/ themes / MY_THEME / modules / blockwishlist / controllers / front / mywishlist.php ),然后我的鈎子將調用我的自定義模塊。 這可能嗎? 據我ModuleFrontController
,您目前無法覆蓋ModuleFrontController
(對不起)。 線索位於Dispatcher::dispatch()
:
case self::FC_MODULE :
$module_name = Validate::isModuleName(Tools::getValue('module')) ? Tools::getValue('module') : '';
$module = Module::getInstanceByName($module_name);
$controller_class = 'PageNotFoundController';
if (Validate::isLoadedObject($module) && $module->active) {
$controllers = Dispatcher::getControllers(_PS_MODULE_DIR_.$module_name.'/controllers/front/');
if (isset($controllers[strtolower($this->controller)])) {
include_once(_PS_MODULE_DIR_.$module_name.'/controllers/front/'.$this->controller.'.php');
$controller_class = $module_name.$this->controller.'ModuleFrontController';
}
}
$params_hook_action_dispatcher = array('controller_type' => self::FC_FRONT, 'controller_class' => $controller_class, 'is_module' => 1);
break;
它僅檢查/modules/?/controllers/
目錄。 您不能覆蓋ModuleFrontController
類,但是如果您足夠聰明,則可以覆蓋Dispatcher
類並使它掃描ModuleFrontController
覆蓋。
通常,在最壞的情況下,有一種方法可以用鈎子來更改所需的東西-通過鈎子注入javascript並更改內容。
嘿,我也在這個問題上苦苦掙扎。 我最終在prestashop論壇上發現了一個解決方案: https : //www.prestashop.com/forums/topic/480523-override-front-controller-of-modules/
用戶Alex已為Dispatcher創建一個替代,它將檢查是否有任何模塊控制器替代。
該文件似乎不再在論壇上可用,但是您仍然可以在這里找到它,以及有關其工作原理的一些解釋: http : //nemops.com/overriding-modules-controllers-in-prestashop-1-6/ #.XDR7HHX0muU
如果這些都不起作用,則代碼如下:
<?php
if (!defined('_PS_VERSION_')) {
exit;
}
class Dispatcher extends DispatcherCore
{
public function dispatch()
{
$controller_class = '';
// Get current controller
$this->getController();
if (!$this->controller) {
$this->controller = $this->useDefaultController();
}
// Dispatch with right front controller
switch ($this->front_controller) {
// Dispatch front office controller
case self::FC_FRONT :
$controllers = Dispatcher::getControllers(
array(_PS_FRONT_CONTROLLER_DIR_, _PS_OVERRIDE_DIR_.'controllers/front/')
);
$controllers['index'] = 'IndexController';
if (isset($controllers['auth'])) {
$controllers['authentication'] = $controllers['auth'];
}
if (isset($controllers['compare'])) {
$controllers['productscomparison'] = $controllers['compare'];
}
if (isset($controllers['contact'])) {
$controllers['contactform'] = $controllers['contact'];
}
if (!isset($controllers[strtolower($this->controller)])) {
$this->controller = $this->controller_not_found;
}
$controller_class = $controllers[strtolower($this->controller)];
$params_hook_action_dispatcher = array(
'controller_type' => self::FC_FRONT,
'controller_class' => $controller_class,
'is_module' => 0,
);
break;
// Dispatch module controller for front office
case self::FC_MODULE :
$module_name = Validate::isModuleName(Tools::getValue('module')) ? Tools::getValue('module') : '';
$module = Module::getInstanceByName($module_name);
$controller_class = 'PageNotFoundController';
if (Validate::isLoadedObject($module) && $module->active) {
$controllers = Dispatcher::getControllers(_PS_MODULE_DIR_.$module_name.'/controllers/front/');
if (isset($controllers[strtolower($this->controller)])) {
include_once(_PS_MODULE_DIR_.$module_name.'/controllers/front/'.$this->controller.'.php');
if (file_exists(
_PS_OVERRIDE_DIR_.'modules/'.$module_name.'/controllers/front/'.$this->controller.'.php'
)) {
include_once(_PS_OVERRIDE_DIR_.'modules/'.$module_name.'/controllers/front/'.$this->controller.'.php');
$controller_class = $module_name.$this->controller.'ModuleFrontControllerOverride';
} else {
$controller_class = $module_name.$this->controller.'ModuleFrontController';
}
}
}
$params_hook_action_dispatcher = array(
'controller_type' => self::FC_FRONT,
'controller_class' => $controller_class,
'is_module' => 1,
);
break;
// Dispatch back office controller + module back office controller
case self::FC_ADMIN :
if ($this->use_default_controller && !Tools::getValue('token') && Validate::isLoadedObject(
Context::getContext()->employee
) && Context::getContext()->employee->isLoggedBack()) {
Tools::redirectAdmin(
'index.php?controller='.$this->controller.'&token='.Tools::getAdminTokenLite($this->controller)
);
}
$tab = Tab::getInstanceFromClassName($this->controller, Configuration::get('PS_LANG_DEFAULT'));
$retrocompatibility_admin_tab = null;
if ($tab->module) {
if (file_exists(_PS_MODULE_DIR_.$tab->module.'/'.$tab->class_name.'.php')) {
$retrocompatibility_admin_tab = _PS_MODULE_DIR_.$tab->module.'/'.$tab->class_name.'.php';
} else {
$controllers = Dispatcher::getControllers(_PS_MODULE_DIR_.$tab->module.'/controllers/admin/');
if (!isset($controllers[strtolower($this->controller)])) {
$this->controller = $this->controller_not_found;
$controller_class = 'AdminNotFoundController';
} else {
// Controllers in modules can be named AdminXXX.php or AdminXXXController.php
include_once(_PS_MODULE_DIR_.$tab->module.'/controllers/admin/'.$controllers[strtolower(
$this->controller
)].'.php');
$controller_class = $controllers[strtolower($this->controller)].(strpos(
$controllers[strtolower($this->controller)],
'Controller'
) ? '' : 'Controller');
}
}
$params_hook_action_dispatcher = array(
'controller_type' => self::FC_ADMIN,
'controller_class' => $controller_class,
'is_module' => 1,
);
} else {
$controllers = Dispatcher::getControllers(
array(
_PS_ADMIN_DIR_.'/tabs/',
_PS_ADMIN_CONTROLLER_DIR_,
_PS_OVERRIDE_DIR_.'controllers/admin/',
)
);
if (!isset($controllers[strtolower($this->controller)])) {
// If this is a parent tab, load the first child
if (Validate::isLoadedObject($tab) && $tab->id_parent == 0 && ($tabs = Tab::getTabs(
Context::getContext()->language->id,
$tab->id
)) && isset($tabs[0])) {
Tools::redirectAdmin(Context::getContext()->link->getAdminLink($tabs[0]['class_name']));
}
$this->controller = $this->controller_not_found;
}
$controller_class = $controllers[strtolower($this->controller)];
$params_hook_action_dispatcher = array(
'controller_type' => self::FC_ADMIN,
'controller_class' => $controller_class,
'is_module' => 0,
);
if (file_exists(_PS_ADMIN_DIR_.'/tabs/'.$controller_class.'.php')) {
$retrocompatibility_admin_tab = _PS_ADMIN_DIR_.'/tabs/'.$controller_class.'.php';
}
}
// @retrocompatibility with admin/tabs/ old system
if ($retrocompatibility_admin_tab) {
include_once($retrocompatibility_admin_tab);
include_once(_PS_ADMIN_DIR_.'/functions.php');
runAdminTab($this->controller, !empty($_REQUEST['ajaxMode']));
return;
}
break;
default :
throw new PrestaShopException('Bad front controller chosen');
}
// Instantiate controller
try {
// Loading controller
$controller = Controller::getController($controller_class);
// Execute hook dispatcher
if (isset($params_hook_action_dispatcher)) {
Hook::exec('actionDispatcher', $params_hook_action_dispatcher);
}
// Running controller
$controller->run();
} catch (PrestaShopException $e) {
$e->displayMessage();
}
}
}
此后,可以通過將替代文件放入以下位置來替代模塊控制器:
override/modules/{moduleName}/controllers/{front/admin}/{filename}.php
在此文件中,您必須定義一個名稱與要覆蓋的類完全相同的類,並在類名的末尾附加“ Override”。
我希望這有幫助
