我在哪里可以找到 prestashop 控制器以及如何扩展它们? [英] where can I find prestashop controllers and how can i extend them?

问题描述

我是 prestashop 的新手，所以如果我问一个非常简单的问题，请耐心等待.我正在创建模块，在我的任务中，我必须扩展由 javascript 中的 ajaxcart.add() 函数调用的购物车控制器.我想知道，响应这个ajax请求的控制器在哪里，我如何在我的模块中扩展这个控制器.有关于这方面的任何好的文档吗?谢谢

I am new to prestashop, so please bear with me if I am asking a very simple question. I am into creating module, and in my task I have to extend the cart controller that is being called by the ajaxcart.add() function in the javascript. I want to know, where is the controller that responds to this ajax request is located, and how can i extend this controller in my module. Are there any good documentation regarding this? thanks

推荐答案

我找到了一种在模块内扩展 prestashop 默认控制器的方法.我查看了 classes/Dispatcher.php 的内部，并在 dispatch() 方法中找到了它

I found a way to extending the prestashop default controllers inside a module. I looked iniside the classes/Dispatcher.php and found this inside the dispatch() method

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);

所以，控制器的命名约定是

So, The naming convention for the controller is

<modulename><controllername>ModuleFrontController

控制器的路径应该是

and the path to the controller should be

module/<module name>/cotrollers/front/<controllername>.php

areacalc 模块中的示例 mycart 控制器

Example mycart controller inside an areacalc module

class areacalcmycartModuleFrontController extends CartController {

areacalc 模块中 mycart 控制器的文件路径

File path to the mycart controller inside an areacalc module

/modules/areacalc/controllers/front/mycart.php

网址是

http://localhost:8080/index.php?fc=module&module=areacalc&controller=mycart
