WordPress是一种使用PHP语言开发的免费开源博客平台,用户可以在支持PHP和MySQL数据库的服务器上架设自己的站点,也可以把WordPress当作一个内容管理系统(CMS)使用。 WordPress 4.9.8 英文版 更新日志:2018-08-03 修复了46处bug、改进,包括自带的2017主题;最大的亮点是「呼吁」用户使用古腾堡编辑器。

SQL 串写错了
$insert=mysql_query("update tb_book set pwd='$xpwd',section='$section',name='$section' where id='$user' AND pwd='pwd'",$conn);
改了之后还是没反应,,,
SQL 串写错了
$insert=mysql_query("update tb_book set pwd='$xpwd',section='$section',name='$section' where id='$user' AND pwd='pwd'",$conn);
请你打开 php 的错误显示功能
请你打开 php 的错误显示功能
开启了 但是还是空白一片
<p class="yy"> <p class="yy"> <p class="yy"> <td><input type="submit" id="xiugai" value="确认修改"/> </td> if(isset($_POST['Submit']) and $_POST['Submit']=="提交"){ 不用解释了吧。。。 </p>已改 但是还是空白。,。 </p> 你没进if if(isset($_POST['xiugai']) and $_POST['xiugai']=="确认修改"){ </p> ... php.ini 中
display_errors = On
重启 web 服务器
你的错误实际产生于 conn/conn.php
如果你的错误显示是打开的话
$insert=mysql_query("update tb_book set pwd='$xpwd',section='$section',name='$section' where id='$user' pwd='pwd'",$conn); //执行更新操作
echo mysql_error(); //这里一定是有输出的,因为 sql 指令错了
conn
<?php$conn=mysql_connect("localhost","root",""); //连接数据库服务器mysql_select_db("db_book",$conn); //连接数据库mysql_query("set names utf8"); //对数据库中编码格式进行转换,避免出现中文乱码的问题?> Object not found!

print_r($_POST); 就能发现是个空数组,怎么都不可能进入if里面。肯定为空了。
把你的form 定义改一改。
