I would like to close page after submitting the form. After running the above code the page is closed after clicking submit button, but the SQL doesn't execute.

Remove onsubmitfrom the formtag. Change this:
onsubmit从form标签中删除。改变这个：
<input type="submit" value="submit" />
To:
到：
<input type="submit" value="submit" name='btnSub' />
And write this:
并写下这个：
if(isset($_POST['btnSub']))
echo "<script>window.close();</script>";

Window.close( ) does not work as it used to. Can be seen here:
Window.close() 不像以前那样工作了。可以在这里看到：
window.close and self.close do not close the window in Chrome
window.close 和 self.close 不会关闭 Chrome 中的窗口
In my case, I realized that I didn't need to close the page. So you can redirect the user to another page with:
就我而言，我意识到我不需要关闭页面。因此，您可以使用以下命令将用户重定向到另一个页面：
window.location.replace("https://stackoverflow.com/");

try onsubmit="submit(); window.close()"
尝试 onsubmit="submit(); window.close()"

If you haveto use the same page as the action, you cannot use onSubmit="window.close();"as it will close the window before the response is received. You have to dinamycally output a JS snippet that closes the window after the SQL data is processed. It would however be far more elegant to use another page as the form action.
如果您必须使用与操作相同的页面，则不能使用，onSubmit="window.close();"因为它会在收到响应之前关闭窗口。您必须在处理 SQL 数据后以动态方式输出关闭窗口的 JS 代码段。然而，使用另一个页面作为表单操作会优雅得多。

That's because the event onsubmitis triggered before the form is submitted.
那是因为该事件onsubmit是在提交表单之前触发的。
Remove your onSubmitand output that JavaScript in your PHP script after you have processed the request. You are closing the window right now, and cancelling the request to your server.
onSubmit处理完请求后，删除并在 PHP 脚本中输出该 JavaScript。您现在正在关闭窗口，并取消对您的服务器的请求。

This worked brilliantly for me, :
这对我来说非常有效，：
$query = "INSERT INTO `table` (...or put your preferred sql stuff)"
$result = mysqli_query($connect, $query);
if($result){
// If everything runs fine with your sql query you will see a message and then the window
//closes
echo '<script language="javascript">';
echo 'alert("Successful!")';
echo '</script>';
echo "<script>window.close();</script>";
}
else {
echo '<script language="javascript">';
echo 'alert("Problem with database or something!")';
echo '</script>';
}
