我正在使用smarty模板。我从表单模板的Smarty代码如下：当表单的action属性保持空白时提交表单？

当我点击提交按钮的形式被重定向到view_users.php页面。但是我没有看到这个页面在表单的action属性中。然后我没有得到这个表格如何重定向到view_users.php。任何人都可以在这方面帮助我，并清除我的疑惑。提前致谢。
：那么页面在表单提交后如何被重定向到页面view_users.ph？ – PHPLover
..你是正确的，但是可能会有一些JS在某个地方在稍后阶段改变动作指向'view_users.php' – naththedeveloper
检查是否有任何提交处理程序在提交时会更改'form action'形成。 –
