是的，您应该在模块帮助程序类中进行表单处理.将任何逻辑排除在模板文件之外，您可以使用mod_mymodule.php调用帮助程序方法并在包含视图文件之前分配变量.

Yes, you should do form processing in module helper class. Keep any logic out of the template file, and you can use mod_mymodule.php to call helper methods and assign variables before including the view file.

请勿设置为表单动作帮助文件！我认为在您的情况下，操作应该在同一页面上，因此您也可以省略操作网址.

Do not set as form action helper file! I think in your case action should be the same page, so you can also ommit action url.

根据评论的要求，这就是您的mod_mymodule.php

As requested in the comments, this would be the content of your mod_mymodule.php

// include helper file
require_once dirname(__FILE__).'/helper.php';
// call some method of the helper class
$items = modMymoduleHelper::getItems();

$moduleclass_sfx = htmlspecialchars($params->get('moduleclass_sfx'));
// render view file from mod_mymodule/tmpl/default.php, $items is available in the view file
require JModuleHelper::getLayoutPath('mod_mymodule', $params->get('layout', 'default'));
