这个出了什么问题???

注意列名称前面可以试试加 `

time = \'' .$row[id]   确定?不是 time = \'' .$row[time] ?

n处错误.
修改后的代码如下:

$con=mysqli_connect('localhost','数据库用户名','数据库密码','数据库名');$re=mysqli_query($con,'SELECT * FROM wdksm');while($row = mysqli_fetch_assoc($re)){$id=$row['id'];    echo '日期:'.$row['time'].'  ';echo '部门:'.$row['bumen'].'  ';echo '姓名:'.$row["name"].'  ';echo ' 职务:'.$row["zhiwu"].'<br />';echo '未打卡时间:'.$row["wdktime"].'<br />';echo '未打卡原因:'.$row["wdkyy"].'<br />';echo '部门责任人审核:'.$row["bmshtime"].'  ';echo '人事行政部/总经理审批:'.$row["rsshtime"].'<br />';echo '<hr /><br />'; }echo '<form name="bc" method="post" action=""> ';echo '<input id="test" name="test" type="text" value="审核" />';echo '<input type="submit" value="审核"/>';echo '</form>';$sql='UPDATE wdksm SET bmshtime = \'' . $_POST['test']  . '\'WHERE id = \'' .$id . '\' ';mysqli_query($con,$sql);
Copy after login

把 '数据库用户名','数据库密码','数据库名' 这三项补上就行了.其他没什么问题

如果你想要mysql连接方式的话,可使用如下对你的源代码进行分析过后的代码:

$query = mysql_query('SELECT * FROM wdksm ');while($row = mysql_fetch_assoc($query)){$id=$row['id'];            //要修改的id号没有被取得,应该在此处获取echo '日期:'.$row["time"].'  ';echo '部门:'.$row["bumen"].'  ';echo '姓名:'.$row["name"].'  ';echo ' 职务:'.$row["zhiwu"].'<br />';echo '未打卡时间:'.$row["wdktime"].'<br />';echo '未打卡原因:'.$row["wdkyy"].'<br />';echo '部门责任人审核:'.$row["bmshtime"].'  ';echo '人事行政部/总经理审批:'.$row["rsshtime"].'<br />';//echo '<input name="" type="button" value="审核" onclick="" />'; //提交按钮放置在表单外,导致表单无法提交echo '<hr /><br />'; }echo '<form name="bc" method="post" action=""> ';echo '<input id="test" name="test" type="text" value="审核" />';echo '<input type="submit" value="审核"/>';   //应在此处加上提交按钮,表单才能成功提交echo '</form>';/*mysql_query('UPDATE wdksm SET bmshtime = \'' . $_POST['test']  . '\'WHERE time = \'' .$row[id] . '\'          //严重错误的sql语句            ');*///正确的sql语句$sql='UPDATE wdksm SET bmshtime = \'' . $_POST['test']  . '\'WHERE id = \'' .$id . '\' ';mysql_query($sql);
Copy after login


执行的结果是成功修改'部门责任人审核'.

主要是sql语句的问题,单引号,双引号一定要区分好,还有就是数据库中的字段的类型,有的需要加引号的不能少

可以使用了,谢谢了。
