推荐答案

如果没有页面提交，这是不可能的！除非您以某种方式将表单字段提交回服务器，即在没有使用jQuery等的页面刷新的情况下进行某种形式的自动保存表单脚本.

This in not possible without a page submit in the first place! Unless you somehow submitted the form fields back to the server i.e. Without Page Refresh using jQuery etc. Somesort of Auto Save Form script.

如果这是用于验证检查，则不需要按照建议进行会话.

If this is for validation checks no need for sessions as suggested.

用户填写表格并提交回自我 服务器端验证失败

User fills in the form and submits back to self Sever side validation fails

$ _ GET

    <input type="hidden" name="first" 
   value="<?php echo htmlspecialchars($first, ENT_QUOTES); ?>" />

验证消息，结束.

或者按照建议将整个帖子保存在一个会话中，类似这样，但是必须再次提交才能上班....

alternatively as suggested save the whole post in a session, something like this, but again has to be first submitted to work....

$ _ POST

if(isset($_POST) & count($_POST)) { $_SESSION['post'] = $_POST; }
if(isset($_SESSION['post']) && count($_SESSION['post'])) { $_POST = $_SESSION['post']; }
