Question

当我在字段（部分，文档标题等）上输入值然后单击提交时，它会显示一个弹出的对话框，它已被发送到数据库（我的php文件中没有错误database-displayQM.php）。当我点击“确定”时，它会重定向到我的主要php文件的表单操作上的另一个页面。它如何保持在同一页面而不是重定向？

这是我的代码：

将操作值保持为空

$qry="SELECT distinct course as c, (SELECT lecturer from courses where course=c limit 1) as l FROM courses";
$results=mysql_query($qry);
if($results)
{
if(mysql_num_rows($results) > 0)
{    
while ($rows = mysql_fetch_array($results))
{
echo "<center><table width=400 border=1>";
echo "<tr><td><b> Course Name : </b></td><td>". $rows["c"]."</td></tr>
<tr><td><b> Lecturer Name : </b></td><td>". $rows["l"]."</td></tr>
<tr><td><b> Time : </b></td>"

    $qry2="SELECT time FROM courses WHERE courses.course='".$rows['c']."' and courses.lecturer='".$rows['l']."'";
    $results2=mysql_query($qry2);
    if($results2)
    {
    while($rows2 = mysql_fetch_array($results2))
    {
    echo"<td>".$rows2['time']."</td>";
    }
    }
    echo"</tr>";
}
echo "</center></table><br>"
}
else {echo "<center>not available</center>";}
}
