[英]How to sent id from one page to another when click on submit?
问题描述
I have a database which consists of question_id, question, and options. 
我有一个由question_id，问题和选项组成的数据库。 Where I'll display the question and options. 我将在其中显示问题和选项。 When the user clicked on submit I want to store the option they clicked and the question_id. 当用户单击提交时，我要存储他们单击的选项和question_id。 I am able to store the option they clicked but want to know how to store the question_id. 我能够存储他们单击的选项，但想知道如何存储question_id。
$user_email = $_SESSION['email'];
$query1="SELECT * FROM votes WHERE user_email='$user_email'";
$query2="SELECT * FROM poll_question WHERE status='1'";
$fetch2 = mysqli_query($con,$query2);

<script type="text/javascript">
$(document).ready(function(){
$(".poll_form").submit(function(event){
event.preventDefault(); //prevents the form from submitting normally
var poll_option = '';
$('button.poll_option').each(function(){
if($(this).prop("checked"))
{
poll_option = $(this).val();
var option=poll_option;
}
var url = '<?php echo SITE_URL; ?>';
});
$.post("poll_vote.php",$('.poll_form').serialize(),
function(data)
{
if(data=="User Created Success"){
window.setTimeout(function () {
location.href ="<?php echo SITE_URL; ?>poll.php";
}, 100);
}
else{
$("#result").html(data);
}
}
);
//to reset form data
});
});
<? } ?>
</script>
</html>
Using th below function I am sending the poll_option to other where I kept the inset operation. 使用下面的函数，我将poll_option发送到其他保留插入操作的位置。 Now I want to send the question_id also 现在我也要发送question_id
