我在哪里可以找到 prestashop 控制器以及如何扩展它们?

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
