js客户端php之问题有点难
- PHP code
<!--Code highlighting produced by Actipro CodeHighlighter (freeware)http://www.CodeHighlighter.com/-->wc();//是一个数据插入自定义函数echo "<script>if(confirm('程序解析的数据正确吗?确定将插入到数据库中,有误请取消本次操作,重新编辑excel文件.')){}else{window.history.go(-1);}</script>";//如果确定则执行wc()函数;如果取消则后退至前一页面,不wc() 函数。wc(插入到数据库中);
我的代码的语句要如何修改?
类似这样的
- JScript code
<!--Code highlighting produced by Actipro CodeHighlighter (freeware)http://www.CodeHighlighter.com/-->return confirm('确定提交吗?/Are you sure?');
能不能执行一个
- PHP code
<!--Code highlighting produced by Actipro CodeHighlighter (freeware)http://www.CodeHighlighter.com/-->exit
------解决方案--------------------
正确流程是
首先客户端提交数据的时候就弹出提示说是否确认
这个时候再form提交给服务器
服务器直接把数据入库。
------解决方案--------------------
<script><br />if(confirm('程序解析的数据正确吗?确定将插入到数据库中,有误请取消本次操作,重新编辑excel文件.')) {<br /> window.location = 'wc.php';<br />}else{<br /> window.history.go(-1);<br />}<br /></script>
在 wc.php 中执行 wc() 函数
------解决方案--------------------
那是因为你的表单数据超出了 post_max_size 的限制

Session in PHP is a mechanism for saving user data on the server side to maintain state between multiple requests. Specifically, 1) the session is started by the session_start() function, and data is stored and read through the $_SESSION super global array; 2) the session data is stored in the server's temporary files by default, but can be optimized through database or memory storage; 3) the session can be used to realize user login status tracking and shopping cart management functions; 4) Pay attention to the secure transmission and performance optimization of the session to ensure the security and efficiency of the application.

Absolute session timeout starts at the time of session creation, while an idle session timeout starts at the time of user's no operation. Absolute session timeout is suitable for scenarios where strict control of the session life cycle is required, such as financial applications; idle session timeout is suitable for applications that want users to keep their session active for a long time, such as social media.

The server session failure can be solved through the following steps: 1. Check the server configuration to ensure that the session is set correctly. 2. Verify client cookies, confirm that the browser supports it and send it correctly. 3. Check session storage services, such as Redis, to ensure that they are running normally. 4. Review the application code to ensure the correct session logic. Through these steps, conversation problems can be effectively diagnosed and repaired and user experience can be improved.
