php和html:form重新加载并显示为空白，并且不提交到数据库

我设计了一个提交到数据库的表单。但当提交时，表格返回空白并重新加载表格。如果你们能帮助我的项目工作，我会很高兴。

我现在是php初学者。我正在努力做一个学校项目。html表单将在哪里查询php表单

我上传了文件，然后尝试了表格。我一直看到一个返回的空白页面，表格没有进入下一页，但返回了空白

表单操作属性为空。

创建一个文件form-action.php(可能在同一个文件夹中(并粘贴代码的第二部分。

然后，在表单动作属性中添加动作页面

action="form action.php">

记住，每个帖子请求都有一个行动页面。当点击继续时，根据输入的名称从表单页面传递到动作页面。

单击"继续"时，将表单数据传递到表单操作页面，并加载form-action.php页面。

如果您想在不重定向新页面(formaction.php(的情况下传递post数据，可以使用jquery-ajax。此次访问

使用PHP 的jQuery Ajax POST示例

您的选择查询无法正常工作，这就是表单无法提交的原因。您的选择查询不会将数据返回到您的输入字段中。因此，请仔细检查您的选择查询，并再次测试输入字段中的数据。您可以使用调试工具来验证数据是否到来，

var_dump(put_variable_name_here);
