覆盖Prestashop模块控制器:哪里放置php文件?

[英]Override Prestashop Module Controller: Where to place php file?

我试图覆盖Prestashop中的模块。 我已经成功覆盖了模块的模板,但是无法成功覆盖模块的控制器。

新的控制器类文件应放在何处?

我尝试了以下位置,但它们未添加新行为(更改任何内容):

〜/ overrides / modules / blockwishlist / controllers / front / mywishlist.php
〜/ themes / MY_THEME / modules / blockwishlist / controllers / front / mywishlist.php

根据我之前的问题,我可以通过编辑核心类(由u / Sergii P推荐)来做到这一点,但是我确定有一种标准方法可以实现,而无需编辑核心类?

以供参考; 这是mywishlist.php的内容:

<?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');
    }

}

编辑:我有一个可能的解决方法,无法覆盖ModuleFrontController类。 目的是在“我的愿望清单”页面上添加一个“导出到CSV”按钮,单击该按钮时,服务器将生成一个包含该愿望清单中所有产品的CSV文件。 在我完成所有工作之前,您能否提供关于是否可行的建议?

  • 将挂钩放置在将调用定制挂钩并链接到定制模块的模板文件中{hook h='displayExportToCsvColumn' mod='myCustomModule'}
  • 创建一个注册新钩子的自定义模块,创建一个呈现表列和按钮的方法,并生成一个CSV文件。
  • 大问题:您可以在模块内部有一个模块吗? 我正在编辑的模板文件位于模块BlockWishlist〜/ themes / MY_THEME / modules / blockwishlist / controllers / front / mywishlist.php ),然后我的钩子将调用我的自定义模块。 这可能吗?

据我ModuleFrontController ,您目前无法覆盖ModuleFrontController (对不起)。 线索位于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;

它仅检查/modules/?/controllers/目录。 您不能覆盖ModuleFrontController类,但是如果您足够聪明,则可以覆盖Dispatcher类并使它扫描ModuleFrontController覆盖。

通常,在最坏的情况下,有一种方法可以用钩子来更改所需的东西-通过钩子注入javascript并更改内容。

嘿,我也在这个问题上苦苦挣扎。 我最终在prestashop论坛上发现了一个解决方案: https : //www.prestashop.com/forums/topic/480523-override-front-controller-of-modules/

用户Alex已为Dispatcher创建一个替代,它将检查是否有任何模块控制器替代。

该文件似乎不再在论坛上可用,但是您仍然可以在这里找到它,以及有关其工作原理的一些解释: http : //nemops.com/overriding-modules-controllers-in-prestashop-1-6/ #.XDR7HHX0muU

如果这些都不起作用,则代码如下:

            $this->controller = $this->useDefaultController();
        }
        // Dispatch with right front controller
        switch ($this->front_controller) {
            // Dispatch front office controller

            $e->displayMessage();

}
  • 将此文件添加到override / classes目录
  • 删除cache / class_index.php文件

此后,可以通过将替代文件放入以下位置来替代模块控制器:

override/modules/{moduleName}/controllers/{front/admin}/{filename}.php

在此文件中,您必须定义一个名称与要覆盖的类完全相同的类,并在类名的末尾附加“ Override”。

我希望这有帮助
