菜鸟求助 怎么在其他字段不变的情况下修改某个字段内容,我现在想修改'部门责任人审核:'这个字段里面的内容,但一直写不进去
while($row = mysql_fetch_assoc($query))
{
echo '日期:'.$row[time].' ';
echo '部门:'.$row[bumen].' ';
echo '姓名:'.$row[name].' ';
echo ' 职务:'.$row[zhiwu].'
';
echo '未打卡时间:'.$row[wdktime].'
';
echo '未打卡原因:'.$row[wdkyy].'
';
echo '部门责任人审核:'.$row[bmshtime].' ';
echo '人事行政部/总经理审批:'.$row[rsshtime].'
';
echo '';
echo '
';
}
echo '';
mysql_query('UPDATE wdksm SET
bmshtime = \'' . $_POST['test'] . '\'
WHERE time = \'' .$row[id] . '\'
');
?>
回复讨论(解决方案)
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);
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);
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。

The best way to send emails is to use the PHPMailer library. 1) Using the mail() function is simple but unreliable, which may cause emails to enter spam or cannot be delivered. 2) PHPMailer provides better control and reliability, and supports HTML mail, attachments and SMTP authentication. 3) Make sure SMTP settings are configured correctly and encryption (such as STARTTLS or SSL/TLS) is used to enhance security. 4) For large amounts of emails, consider using a mail queue system to optimize performance.

Sending mail using PHP and SMTP can be achieved through the PHPMailer library. 1) Install and configure PHPMailer, 2) Set SMTP server details, 3) Define the email content, 4) Send emails and handle errors. Use this method to ensure the reliability and security of emails.

The reason for using Dependency Injection (DI) is that it promotes loose coupling, testability, and maintainability of the code. 1) Use constructor to inject dependencies, 2) Avoid using service locators, 3) Use dependency injection containers to manage dependencies, 4) Improve testability through injecting dependencies, 5) Avoid over-injection dependencies, 6) Consider the impact of DI on performance.
