        $this->renderLayout();
        //exit($product_id);
    }
    public function saveAction()
    {
        exit("Save");
    }
}

请在Form.php退出中查看不起作用，我认为它的意思是这个形式没有被称为，我不知道为什么。

Answer 1

我在edit.php档案

中遇到了同样的错误

现在位于 _construct（）功能

内

添加以下行：

$this->_blockGroup = 'your block group here';

希望这会有用

感谢

Answer 2

在此处仔细检查您的阻止名称： edit.php

$ this-＆gt; _blockGroup ='your_block_group / group_name';

如果您没有此行，请将其添加到您的edit.php

享受编码....

感谢
